    MEMORANDUM OPINION
    I.    INTRODUCTION
    In 2008, in the context of a dispute over whether the Committee on the Judiciary
    of the House of Representatives (“the Judiciary Committee”) had the power to compel
    former White House Counsel Harriet Miers and then-White House Chief of Staff Joshua
    Bolten to testify and produce documents in connection with a congressional
    investigation, the Department of Justice (“DOJ”) made three legal contentions of
    “extraordinary constitutional significance.” Comm. on Judiciary, U.S. House of
    Representatives v. Miers, 
    558 F. Supp. 2d 53
    , 55 (D.D.C. 2008) (Bates, J.). First, DOJ
    argued that a duly authorized committee of Congress acting on behalf of the House of
    Representatives cannot invoke judicial process to compel the appearance of senior-level
    aides of the President for the purpose of receiving sworn testimony. See 
    id. at 66–67,
    78. Second, DOJ maintained that a President can demand that his aides (both current
    and former) ignore a subpoena that Congress issues, on the basis of alleged absolute
    testimonial immunity. See 
    id. at 100.
    And, third, DOJ asserted that the federal courts
    cannot exercise subject-matter jurisdiction over any such subpoena-related stalemate
    between the Legislature and the Executive branch, on separation of powers grounds.
    See 
    id. at 72–73,
    93–94. The district court that considered these propositions rejected
    each one in a lengthy opinion that thoroughly explained why the federal courts have
    subject-matter jurisdiction over such disputes, see 
    id. at 64–65;
    why the Judiciary
    Committee had standing to sue and a cause of action to proceed in federal court, see 
    id. at 65–94;
    and why the claim that a President’s senior-level aides have absolute
    testimonial immunity is meritless, see 
    id. at 99–107.
    Most importantly, the Miers
    opinion also persuasively demonstrated that DOJ’s conception of the limited power of
    both Congress and the federal courts relative to the expansive authority of the
    President—which, purportedly, includes the power to shield himself and his aides from
    being questioned about any aspect of their present or former White House work—is not
    grounded in the Constitution or in any other federal law. See 
    id. at 99,
    106–07; cf.
    Comm. on Oversight & Gov’t Reform v. Holder, 
    979 F. Supp. 2d 1
    , 10–11 (D.D.C.
    2013).
    The more things change, the more they stay the same. On May 20, 2019,
    President Donald J. Trump directed former White House Counsel Donald F. McGahn II
    to decline to appear before the Judiciary Committee in response to a subpoena that the
    Committee had issued to McGahn in connection with its investigation of Russia’s
    interference into the 2016 presidential election and the Special Counsel’s findings of
    fact concerning potential obstruction of justice by the President. (See Letter from Pat
    A. Cipollone, Counsel to the President, to William A. Burck (May 20, 2019), Ex. E to
    Decl. of Michael M. Purpura (“Purpura Decl.”), ECF No. 32-3, at 46–47.) 1 Months of
    negotiations ensued, which produced no testimony from McGahn, and on August 7,
    2019, the Judiciary Committee filed the instant lawsuit. Invoking Article I of the U.S.
    Constitution, the Judiciary Committee implores this Court to “[d]eclare that McGahn’s
    refusal to appear before the Committee in response to the subpoena issued to him was
    without legal justification” (Compl., ECF No. 1, at 53), and it also seeks an “injunction
    ordering McGahn to appear and testify forthwith before the Committee” (id.).
    1
    Page number citations to the documents that the parties have filed refer to those that the Court’s
    electronic case filing system automatically assigns.
    2
    The Judiciary Committee and DOJ (which is representing McGahn in the instant
    legal action) have now filed the cross-motions for summary judgment, which are before
    this Court at present. (See Pl.’s Mot. for Prelim. Inj. or, in the alternative, for
    Expedited Partial Summ. J. (“Pl.’s Mot.”), ECF No. 22; Def.’s Mot. for Summ. J.
    (“Def.’s Mot.”), ECF No. 32.) In its motion, the Judiciary Committee reiterates the
    basic contention that, having received a subpoena from a duly authorized committee of
    Congress exercising its investigative powers under Article I of the Constitution,
    “McGahn is legally obligated to testify” (Mem. in Supp. of Pl.’s Mot. (“Pl.’s Mem.”),
    ECF No. 22-1, at 14), and “has no valid interest in defying the Committee’s subpoena”
    (
    id. at 54).
    In response, DOJ renews its (previously unsuccessful) threshold objections
    to the standing and right of the Judiciary Committee to seek to enforce its subpoenas to
    senior-level presidential aides in federal court, and it also robustly denies that federal
    courts have the authority to exercise subject-matter jurisdiction over subpoena-
    enforcement claims brought by House committees with respect to such Executive
    branch officials. (See Def.’s Mot. at 32–33, 43, 53); see also 
    Miers, 558 F. Supp. 2d at 65
    –94. DOJ further insists that the Judiciary Committee’s claim that McGahn is legally
    obligated to testify fails on its merits, primarily because DOJ’s Office of Legal Counsel
    (“OLC”) has long maintained that present and former senior-level aides to the
    President, such as McGahn, are absolutely immune from being compelled to testify
    before Congress if the President orders them not to do so. (See Def.’s Mot. at 60–74.)
    For the reasons explained in this Memorandum Opinion, as well as those laid out
    in Miers, the Judiciary Committee’s motion for partial summary judgment is
    GRANTED, and DOJ’s cross-motion for summary judgment is DENIED. In short, this
    3
    Court agrees with Judge Bates’s conclusion that federal courts have subject-matter
    jurisdiction to resolve legal disputes that arise between the Legislature and the
    Executive branch concerning the scope of each branch’s subpoena-related rights and
    duties, under section 1331 of Title 28 of the United States Code and the Constitution.
    See 
    Miers, 558 F. Supp. 2d at 64
    –65. Jurisdiction exists because the Judiciary
    Committee’s claim presents a legal question, and it is “emphatically” the role of the
    Judiciary to say what the law is. Marbury v. Madison, 5 U.S. (1 Cranch) 137, 177
    (1803). It also plainly advances constitutional separation-of-powers principles, rather
    than subverts them, when a federal court decides the question of whether a legislative
    subpoena that a duly authorized committee of the House of Representatives has issued
    to a senior-level aide of the President is valid and enforceable, or, alternatively, is
    subject to the President’s invocation of absolute testimonial immunity. Furthermore,
    Miers was correct to conclude that, given the indisputable Article I power of the House
    of Representatives to conduct investigations of potential abuses of power and subpoena
    witnesses to testify at hearings concerning such investigations, the Judiciary Committee
    has both standing and a cause of action to file an enforcement lawsuit in federal court if
    the Executive branch blocks a current or former presidential aides’ performance of his
    duty to respond to a legislative subpoena. See 
    id. at 65–75,
    78–94.
    DOJ’s arguments to the contrary are rooted in “the Executive’s interest in
    ‘autonomy[,]’” and, therefore, “rest[] upon a discredited notion of executive power and
    privilege.” 
    Id. at 103.
    Indeed, when DOJ insists that Presidents can lawfully prevent
    their senior-level aides from responding to compelled congressional process and that
    neither the federal courts nor Congress has the power to do anything about it, DOJ
    4
    promotes a conception of separation-of-powers principles that gets these constitutional
    commands exactly backwards. In reality, it is a core tenet of this Nation’s founding
    that the powers of a monarch must be split between the branches of the government to
    prevent tyranny. See The Federalist No. 51 (James Madison); see also Buckley v.
    Valeo, 
    424 U.S. 1
    , 120 (1976). Thus, when presented with a case or controversy, it is
    the Judiciary’s duty under the Constitution to interpret the law and to declare
    government overreaches unlawful. Similarly, the House of Representatives has the
    constitutionally vested responsibility to conduct investigations of suspected abuses of
    power within the government, and to act to curb those improprieties, if required.
    Accordingly, DOJ’s conceptual claim to unreviewable absolute testimonial immunity on
    separation-of-powers grounds—essentially, that the Constitution’s scheme
    countenances unassailable Executive branch authority—is baseless, and as such, cannot
    be sustained.
    During the hearing that this Court held regarding the parties’ cross-motions for
    summary judgment, the Court asked DOJ’s counsel whether its absolute immunity
    assertion with respect to McGahn was somehow different than the absolute immunity
    that former White House Counsel Harriet Miers had claimed, or whether it was DOJ’s
    position that the Miers case was simply wrong to conclude that absolute testimonial
    immunity is not an available legal basis for thwarting compelled congressional process
    with respect to senior-level presidential aides. Counsel answered “both.” (Hr’g Tr.,
    ECF No. 44, at 31:5–10.) Upon review of the motions and the relevant law, however, it
    is clear to this Court that the correct response to its inquiry is “neither.” That is, the
    United States District Court for the District of Columbia has seen these same facts and
    5
    these same legal arguments before, and DOJ has done little to persuade this Court that
    the case should turn out differently in the end. Instead, this Court concurs with the
    thrust of Miers’s conclusion that, whatever the scope of the President’s executive
    privilege with respect to the information that Congress seeks to compel, and whatever
    the merits of DOJ’s assertion that senior-level aides are the President’s “alter egos” for
    the purpose of invoking an immunity, DOJ has failed to bridge the yawning gap
    between a presidential aide’s right to withhold privileged information in the context of
    his or her compelled congressional testimony (which no one disputes), and the
    President’s purported power to direct such aides to refuse to show up and be questioned
    at all (which appears only in a string of OLC opinions that do not themselves constitute
    legal precedents and are manifestly inconsistent with the constitutional jurisprudence of
    the Supreme Court and the D.C. Circuit in many respects).
    Thus—to be crystal clear—what is at issue in this case is solely whether senior-
    level presidential aides, such as McGahn, are legally required to respond to a subpoena
    that a committee of Congress has issued, by appearing before the committee for
    testimony despite any presidential directive prohibiting such a response. The Court
    distinguishes this issue from the very different question of whether the specific
    information that high-level presidential aides may be asked to provide in the context of
    such questioning can be withheld from the committee on the basis of a valid privilege.
    In other words, “the Court only resolves, and again rejects, the claim by the Executive
    to absolute immunity from compelled congressional process for senior presidential
    aides.” 
    Miers, 558 F. Supp. 2d at 56
    ; see also 
    id. (noting that
    “[t]he specific claims of
    executive privilege that [a subpoenaed presidential aide] may assert are not addressed—
    6
    and the Court expresses no view on such claims”). And in reaching this conclusion,
    “[t]he Court holds only that [McGahn] (and other senior presidential advisors) do not
    have absolute immunity from compelled congressional process in the context of this
    particular subpoena dispute.” 
    Id. at 105–06.
    Accordingly, just as with Harriet Miers
    before him, Donald McGahn “must appear before the Committee to provide testimony,
    and invoke executive privilege where appropriate.” 
    Id. at 106.
    II.    BACKGROUND
    A.      Factual Background
    The material facts that underlie this lawsuit are not in dispute. On March 4,
    2019, the Judiciary Committee opened an investigation into allegations that President
    Trump and his associates had engaged in various forms of misconduct during the lead
    up to the 2016 presidential election and in the years since. (See Pl.’s Stmt. of Material
    Facts Not in Dispute (“Pl.’s Stmt. of Facts”), ECF No. 22-4, ¶ 75 (citing Press Release,
    H. Comm. on the Judiciary, House Judiciary Committee Unveils Investigation Into
    Threats Against the Rule of Law (Mar. 4, 2019)); see also H.R. Rep. No. 116-105, at 13
    (2019) (announcing an investigation into “possible malfeasance, abuse of power,
    corruption, obstruction of justice, or other misconduct on the part of the President or
    other members of his Administration”).) 2 In its complaint, the Judiciary Committee
    alleges that one of the driving forces behind its investigation is the separate
    investigation that Special Counsel Robert S. Mueller III conducted between 2017 and
    2019 regarding alleged Russian interference in the 2016 presidential election, the
    2
    This investigation pre-dates the formal impeachment inquiry that the Speaker of the House announced
    on September 24, 2019. See Press Release, Speaker Nancy Pelosi, Pelosi Remarks Announcing
    Impeachment Inquiry (Sept. 24, 2019), https://www.speaker.gov/newsroom/92419-0.
    7
    results of which are memorialized in a 448-page report that the Special Counsel’s
    Office issued on March 22, 2019. (See Compl., ECF No. 1, ¶¶ 1–3 (citing Robert S.
    Mueller III, Report On The Investigation Into Russian Interference In The 2016
    Presidential Election (March 2019) (“Mueller Report”).) In the complaint, the
    Judiciary Committee invokes the Mueller Report when describing the purposes of its
    investigation, which allegedly include determining “whether the conduct uncovered
    may warrant amending or creating new federal authorities, including among other
    things, relating to election security, campaign finance, misuse of electronic data, and
    the types of obstructive conduct that the Mueller Report describes”; and “whether any
    of the conduct described in the Special Counsel’s Report warrants the Committee in
    taking any further steps under Congress’ Article I powers . . . includ[ing] whether to
    approve articles of impeachment with respect to the President or any other
    Administration official.” (Compl. ¶ 61 (quoting H.R. Rep. No. 116-105, at 13 (internal
    quotation marks omitted)).)
    The Special Counsel’s investigation and findings have been summarized
    elsewhere, see, e.g., In re Application of Comm. on Judiciary, U.S. House of
    Representatives, for an Order Authorizing Release of Certain Grand Jury Materials,
    No. 19-gj-48, 
    2019 WL 5485221
    , at *2–7 (D.D.C. Oct. 25, 2019). In any event, this
    Court need not detail them here. It suffices to note that investigators from the Special
    Counsel’s office interviewed McGahn on several separate occasions—the Mueller
    Report indicates that the interviews with McGahn took place on at least five different
    dates (see Compl. ¶ 94)—and it is also noteworthy that McGahn’s statements to those
    investigators are specifically mentioned in the Mueller Report multiple times and in
    8
    connection with various topics, including the resignation of National Security Advisor
    Michael Flynn (see 
    id. ¶ 35);
    the termination of FBI Director James Comey (see 
    id. at 65–69);
    the decision by Attorney General Jefferson B. Sessions III to recuse himself
    from overseeing the Special Counsel’s investigation (see 
    id. ¶ 36);
    and President
    Trump’s alleged attempts to remove Special Counsel Mueller (see 
    id. ¶ 35).
    Following
    the release of the Mueller Report, President Trump made a number of comments in
    which he appeared to call into question the veracity of what McGahn had told the
    Special Counsel. (See Pl.’s Stmt. of Facts ¶¶ 70–74 (citations omitted).)
    On March 4, 2019, in conjunction with the Judiciary Committee’s investigation,
    Jerrold Nadler, the Chairman of the Judiciary Committee, sent a letter to McGahn
    asking that he voluntarily provide the Committee with certain documents delineated in
    an attachment to his letter. (See Letter from Jerrold Nadler, Chairman H. Comm. on the
    Judiciary, to Donald F. McGahn II (Mar. 4, 2019), Ex. R to Decl. of Todd B. Tatelman
    (“Tatelman Decl.”), ECF No. 22-3.) In response to this request, McGahn’s private
    attorney, William Burck, sent a letter to Chairman Nadler on March 18, 2019,
    indicating that Burck had forwarded the document request to the White House and to
    the Trump Campaign, because those entities “are the appropriate authorities to decide
    the scope of access to these documents, including whether a claim of executive,
    attorney-client and/or attorney work product privilege would protect such information
    from disclosure.” (Letter from William A. Burck to Jerrold Nadler, Chairman H.
    Comm. on the Judiciary (Mar. 18, 2019), Ex. S to Compl., ECF No. 1-19.) When the
    Judiciary Committee had not received a response to its voluntary document request as
    of April 22, 2019, it issued a subpoena ad testificandum to McGahn (see Subpoena to
    9
    Donald F. McGahn II (“Subpoena”), Ex. U to Tatelman Decl., ECF No. 22-3 at 497–
    508), pursuant to a resolution that the Committee had adopted on April 3, 2019,
    authorizing the issuance of subpoenas in conjunction with its investigation (see Pl.’s
    Stmt. of Facts ¶ 84). The subpoena instructed McGahn to produce documents
    pertaining to 36 specific topics, including the FBI’s investigation of Michael Flynn, the
    termination of James Comey, Jeff Sessions’s recusal decision, and the Special
    Counsel’s investigation, by no later than May 7, 2019 (see Subpoena at 497, 499–501),
    and it also called for McGahn to appear to testify before the Judiciary Committee on
    May 21, 2019 (id. at 497).
    On May 7, 2019, White House Counsel Pat Cipollone sent a letter to Burck in
    which he relayed instructions to McGahn from the Acting Chief of Staff to the
    President, Mick Mulvaney. (See Letter from Pat A. Cipollone, Counsel to the
    President, to William A. Burck (May 7, 2019), Ex. C to Purpura Decl., ECF No. 32-3, at
    30.) The letter explained that McGahn was “not to produce White House records in
    response to the Committee’s April 22 subpoena” on the grounds that the requested
    records “remain legally protected from disclosure under longstanding constitutional
    principles, because they implicate significant Executive Branch confidentiality interests
    and executive privilege.” (Id.) Cipollone contemporaneously sent Judiciary Committee
    Chairman Nadler a letter making the same points about the protected nature of the
    documents, and informing him of the instructions that the White House had provided to
    McGahn. (See Letter from Pat A. Cipollone, Counsel to the President, to Jerrold
    Nadler, Chairman H. Comm. on the Judiciary (May 7, 2019), Ex. C to Purpura Decl.,
    ECF No. 32-3, at 31.) Cipollone’s letter to Nadler indicated that the White House
    10
    Counsel’s Office would be making the decision as to whether or not McGahn would
    respond to the Committee’s subpoena. (See 
    id. (asserting that
    the White House
    Counsel’s Office “will respond to the Committee concerning its interest in the
    records”).)
    On that same day, Chairman Nadler sent a letter to Burck in which he
    emphasized that, absent a court order directing otherwise, McGahn must appear before
    the Committee and testify on May 21, 2019, or the Committee would hold him in
    contempt. (See Letter from Jerrold Nadler, Chairman H. Comm. on the Judiciary, to
    William A. Burck (May 7, 2019), Ex. II to Compl., ECF No. 1-35, at 3.) Chairman
    Nadler followed up on May 17, 2019, with a letter to McGahn, via his counsel,
    reemphasizing that it was the Committee’s expectation that he appear, and explaining
    that, because the Committee intended “to focus on the very topics covered in the
    Special Counsel’s Report . . . there can be no valid assertion of executive privilege
    given that President Trump declined to assert any privilege over Mr. McGahn’s
    testimony, or over any portion of the Report itself.” (See Letter from Jerrold Nadler,
    Chairman H. Comm. on the Judiciary, to Donald F. McGahn II (May 17, 2019), Ex. W
    to Compl., ECF No. 1-23, at 2 (internal quotation marks and citation omitted).) Nadler
    closed this letter by stating that “even if the President . . . invokes executive privilege
    over your testimony, and you decide to abide by that improper assertion, you are still
    required under the law and the penalty of contempt to ‘appear before the Committee to
    provide testimony, and invoke executive privilege where appropriate.’” (Id. at 2
    (quoting 
    Miers, 558 F. Supp. 2d at 106
    ).)
    11
    On May 20, 2019, the day before McGahn was to testify before the Committee,
    Cipollone sent a letter to Burck stating that President Trump was instructing McGahn
    not to appear at the scheduled hearing. (See Letter from Pat A. Cipollone, Counsel to
    the President, to William A. Burck (May 20, 2019), Ex. E to Purpura Decl., ECF No.
    32-3, at 46–47.) Cipollone attached to his letter a memorandum from the Office of
    Legal Counsel which opines that, as a former “senior advisor” to the President, McGahn
    is protected by “testimonial immunity” and that “Congress may not constitutionally
    compel [him] to testify about [his] official duties.” (Id. at 48.) 3 Cipollone also sent a
    letter to Chairman Nadler informing him of the instructions that had been provided to
    McGahn. (See Letter from Pat A. Cipollone, Counsel to the President, to Jerrold
    Nadler, Chairman H. Comm. on the Judiciary (May 20, 2019), Ex. 2 to Decl. of Barry
    H. Berke (“Berke Decl.”), ECF No. 22-2, at 21–22.) That same day, Burck sent a letter
    to Chairman Nadler informing him of this development and stating that, as a result of
    the President’s instructions, McGahn was “facing contradictory instructions from two
    co-equal branches of government.” (Letter from William A. Burck to Jerrold Nadler,
    Chairman H. Comm. on the Judiciary (May 20, 2019), Ex. X to Tatelman Decl., ECF
    No. 22-3, at 510.) Burck further explained that he found the OLC’s opinion
    “persuasive” and that, “[u]nder these circumstances, and also conscious of the duties
    [McGahn], as an attorney, owes to his former client, Mr. McGahn must decline to
    appear at the hearing tomorrow.” (Id.) Burck concluded his letter by stating that
    McGahn “remains obligated to maintain the status quo and respect the President’s
    3
    This memorandum would later be published as an OLC slip opinion. See Testimonial Immunity
    Before Cong. of the Former Counsel to the President, 43 Op. O.L.C. ___, Slip. Op. (May 20, 2019)
    (“McGahn OLC Mem.”).
    12
    instruction[,]” but that if the Committee and Executive were to reach an
    accommodation, McGahn “would of course comply with that accommodation.” (Id. at
    511.)
    Nadler responded immediately to McGahn, via his counsel, with a letter in which
    he described President Trump’s command to McGahn not to appear as “unprecedented”
    and insufficient “to excuse your obligation to appear before the Committee.” (Letter
    from Jerrold Nadler, Chairman H. Comm. on the Judiciary, to Donald F. McGahn II
    (May 20, 2019), Ex. Z to Tatelman Decl., ECF No. 22-3, at 544.) In his letter, Nadler
    noted that the Miers case had rejected the contention that a former White House
    Counsel could refuse to appear in response to a congressional subpoena by virtue of
    absolute testimonial immunity (see id.), and he informed McGahn that it was the
    Committee’s position that McGahn was “‘not excused from compliance with the
    Committee’s subpoena by virtue of a claim of executive privilege that may ultimately
    be made’” (id. at 546 (quoting 
    Miers, 558 F. Supp. 2d at 106
    )). Rather, the Committee
    expected McGahn to appear at the hearing and invoke executive privilege where
    appropriate, as Judge Bates had ordered former White House Counsel Harriet Miers to
    do. (See id.)
    Ultimately, as a result of the White House’s invocation of absolute testimonial
    immunity, McGahn did not appear to testify on May 21 (see Pl.’s Stmt. of Facts ¶¶ 91,
    93), and on May 31, 2019, Nadler sent a letter to McGahn and Cipollone in which the
    Committee offered to accept a modified privilege log with respect to subpoenaed
    documents being withheld on the basis of privilege, and belated production of non-
    privileged documents. (See Letter from Jerrold Nadler, Chairman H. Comm. on the
    13
    Judiciary, to Donald F. McGahn II and Pat A. Cipollone, Counsel to the President (May
    31, 2019), Ex. Z to Tatelman Decl., ECF No. 22-3, at 536.) Nadler also offered “to
    discuss any reasonable accommodation(s) that would facilitate Mr. McGahn’s
    appearance before the Committee,” and he proposed a number of options “including
    limiting the testimony to the specific events detailed in the Special Counsel’s report,
    identifying with greater specificity the precise areas of intended inquiry, and agreeing
    to the presence of White House counsel during any testimony, so that Mr. McGahn may
    consult regarding the assertion of executive privilege.” (Id. at 537.) The Judiciary
    Committee did not receive any response to this letter. (See Pl.’s Stmt. of Facts ¶ 96.)
    On June 17, 2019, a call took place between representatives of the Judiciary
    Committee and the White House, during which the Committee once again offered to
    limit the scope of any testimony from McGahn. (See Berke Decl. ¶ 8.) Follow-up calls
    regarding potential accommodations took place on June 18, 2019, and on June 21, 2019,
    and there was an in-person meeting on June 25, 2019, but no resolution was reached.
    (See 
    id. ¶¶ 9–11.)
    During a subsequent call on July 1, 2019, the White House indicated
    that it “was not willing to accept any accommodation involving Mr. McGahn’s public
    testimony.” (Id. ¶ 12.) However, the White House did offer “to consider allowing Mr.
    McGahn to appear for a private interview rather than for public testimony, subject to
    appropriate conditions that the parties would have to negotiate.” (Purpura Decl. ¶ 18.)
    In response, the Judiciary Committee indicated that it “was not willing to consider
    anything other than testimony at a public hearing.” (Id. ¶ 19.) Another call took place
    on July 12, 2019, during which the Committee reiterated its slate of proposed
    accommodations, including limiting McGahn’s testimony to the Mueller Report and
    14
    allowing White House counsel to sit behind McGahn during his testimony, and it also
    offered to negotiate any issues that arose during his testimony. (See Berke Decl. ¶ 13.)
    The White House rejected this proposal during a subsequent call that took place on July
    17, 2019 (see 
    id. ¶ 14),
    and, separately, McGahn’s counsel reaffirmed that McGahn
    would continue to comply with the President’s directive not to testify (id. ¶ 15–16).
    Although the White House and the Committee were not able to resolve their
    differences with respect to McGahn’s testimony, they did reach an agreement regarding
    his production of the subpoenaed documents. (See Purpura Decl. ¶ 21.) Under this
    agreement, the White House would make responsive documents available to the
    Judiciary Committee after privilege review, subject to certain terms and conditions
    regarding access to and dissemination of the documents. (See id.) 4
    B.      Committee on Judiciary, U.S. House of Representatives v. Miers
    One who doubts that history repeats itself need look back no further than an
    investigation that the Judiciary Committee conducted in 2007, with respect to the forced
    resignation of seven United States Attorneys, to prove the point. In that dispute, the
    Executive branch likewise refused to comply with voluntary requests, and following an
    authorizing vote, the Judiciary Committee issued a subpoena to Harriet Miers, former
    White House Counsel to President George W. Bush. The Judiciary Committee’s
    subpoena required that Miers produce documents and appear before the Committee to
    give testimony regarding any influence that the White House may have exerted over
    4
    The White House also initially asserted testimonial immunity with respect to former aide Hope Hicks,
    (see Letter from Pat A. Cipollone, Counsel to the President, to Jerrold Nadler, Chairman H. Comm. on
    the Judiciary (June 18, 2019), Ex. CC to Compl., ECF No. 1-29), but Hicks ultimately appeared for a
    voluntary interview, during which White House and OLC objected to her answering numerous questions
    on the basis of “absolute immunity” (see, e.g., Transcribed Interview of Hope Hicks, H. Comm. on the
    Judiciary, 116th Cong. (June 19, 2019), Ex. EE to Compl., ECF No. at 12, 15–16).
    15
    DOJ’s decision to request the resignations of various United States Attorneys, some of
    whom were in the process of investigating prominent politicians or had rebuffed
    requests from Republican officials to undertake certain investigations. Miers, 558 F.
    Supp. 2d at 57–63. In response to the Judiciary Committee’s subpoena, the Executive
    branch asserted that all of the documents sought were protected by executive privilege,
    and, accordingly, the White House informed the Committee that no documents would be
    forthcoming. See 
    id. at 62.
    5 With respect Miers’s testimony, President Bush initially
    asserted executive privilege as well, but the White House ultimately took the position
    that “Miers was absolutely immune from compelled congressional testimony[.]” 
    Id. In support
    of this legal position, the White House proffered an OLC opinion to this effect.
    See id.; see also Immunity of Former Counsel to the President from Compelled
    Congressional Testimony, 
    31 Op. O.L.C. 191
    (2007).
    Thereafter, the Judiciary Committee filed a lawsuit seeking a court order and a
    declaration that, among other things, “Miers must comply with a subpoena and appear
    before the Committee to testify[.]” 
    Miers, 558 F. Supp. 2d at 55
    . In response, the
    Executive branch “moved to dismiss this action in its entirety on the grounds that the
    Committee lacks standing and a proper cause of action, that disputes of this kind are
    non-justiciable, and that the Court should exercise its discretion to decline jurisdiction.”
    
    Id. at 55–56.
    On the merits, the Executive branch asserted that “sound principles of
    separation of powers and presidential autonomy dictate that the President’s closest
    advisors must be absolutely immune from compelled testimony before Congress[.]” 
    Id. 5 The
    Committee also issued a subpoena seeking the production of documents to then-current White
    House Chief of Staff Joshua Bolten. 
    Miers, 558 F. Supp. 2d at 61
    .
    16
    at 56. For its part, the Judiciary Committee filed a cross-motion for partial summary
    judgment that argued that Miers had no legal right to refuse to appear and that there was
    no legal basis for the assertion of absolute testimonial immunity. See 
    id. at 99.
    Judge Bates resolved the parties’ contentions in a detailed, 93-page slip opinion
    that ultimately denied the Executive branch’s motion and granted the Committee’s
    motion, thereby requiring Miers to appear and testify. 
    Id. at 108.
    At the outset of his
    opinion, Judge Bates addressed the question of federal question subject-matter
    jurisdiction under 28 U.S.C. § 1331 (even though both parties conceded its existence)
    and found that section 1331 was the source of the court’s subject-matter jurisdiction
    over the dispute. See 
    id. 64–65. Turning
    to the question of standing, Judge Bates found
    that a prior decision from the D.C. Circuit—United States v. AT & T, 
    551 F.2d 384
    (D.C. Cir. 1976) (“AT & T I”)—was “on point and establishe[d] that the Committee has
    standing to enforce its duly issued subpoena through a civil suit.” 
    Id. at 68.
    Noting
    that general subpoena enforcement disputes are common in federal courts, Judge Bates
    further concluded that “this sort of dispute is traditionally amenable to judicial
    resolution and consequently justiciable[,]” 
    id. at 68,
    71, and that “courts have
    entertained subpoena enforcement actions (or motions to quash subpoenas) where the
    political branches have clashed over congressional subpoenas[,]” 
    id. at 71;
    see also 
    id. at 70
    (explaining that “the [Supreme] Court has never held that an institution, such as
    the House of Representatives, cannot file suit to address an institutional harm”).
    Turning next to the Executive branch’s contentions regarding the lack of a cause
    of action, Judge Bates found that, through the Declaratory Judgment Act, the Judiciary
    Committee could enforce the House’s constitutional “‘power of inquiry[,]’” and that the
    17
    associated “‘process to enforce’” that constitutional interest was “‘an essential and
    appropriate auxiliary to the legislative function.’” 
    Id. at 75
    (quoting McGrain v.
    Daugherty, 
    273 U.S. 135
    , 174 (1927)). Judge Bates also concluded that the Judiciary
    Committee had a limited “implied cause of action . . . to seek a declaratory judgment
    concerning the exercise of its subpoena power[,]” which derived from the House’s
    Article I legislative functions. 
    Id. at 95.
    With respect to whether the court should exercise its equitable discretion and
    thus decline to decide the parties’ dispute based on separation-of-powers concerns,
    Judge Bates rejected “the contention that judicial intervention in this arena at the
    request of Congress would be unprecedented in the nation’s history[,]” 
    id. at 95–96,
    and
    also found that, because the Judiciary is the ultimate arbiter when it comes to claims of
    executive privilege, declining to consider the case would be more harmful to the
    balance of powers between the three Branches than deciding the case, see 
    id. at 96.
    Judge Bates further dismissed the Executive branch’s argument that a ruling would
    open the floodgates of litigation, noting that the possibility for such litigation has
    existed since the Nixon era. See 
    id. Having resolved
    the threshold issues, Judge Bates then turned to the merits of the
    case. See 
    id. at 99.
    He “reject[ed] the Executive’s claim of absolute immunity for
    senior presidential aides” and began his discussion of such immunity by noting that
    “[t]he Executive cannot identify a single judicial opinion that recognizes absolute
    immunity for senior presidential advisors in this or any other context.” 
    Id. Judge Bates
    explained that the Supreme Court’s decision in Harlow v. Fitzgerald, 
    457 U.S. 800
    (1982)—in which the Court rejected absolute immunity for Executive aides in the
    18
    context of civil lawsuits seeking monetary damages, except possibly where the aides
    were involved in the areas of national security or foreign policy—“virtually foreclosed”
    the absolute testimonial immunity argument that the defendants were advancing. 
    Id. at 100.
    And Judge Bates found it telling that “the only authority that the Executive can
    muster in support of its absolute immunity assertion are two OLC, which he found to be
    “for the most part[,] conclusory and recursive.” 
    Id. at 104.
    6 Thus, Judge Bates
    declared that Miers was not immune from compelled congressional process, and
    therefore, was legally required to “appear before the Committee to provide testimony,
    and invoke executive privilege where appropriate.” 
    Id. at 106;
    see also 
    id. at 108.
    The coda to the Miers case is that the Executive branch appealed Judge Bates’s
    decision, but the parties reached a settlement, and the Executive branch subsequently
    dismissed its appeal. Notably, as an explicit condition of the settlement agreement, the
    Executive branch agreed not to request that Judge Bates vacate or set aside his opinion.
    See Letter from Irvin B. Nathan to Michael F. Hertz (Mar. 5, 2009), Comm. on
    Judiciary, U.S. House of Representatives v. Miers, No. 08-cv-0409, ECF No. 68-1, at 8–
    9 (Oct. 22, 2019). Consequently, the Miers Memorandum Opinion and Order remained
    in effect, and as it turns out, that case represents the only definitive legal ruling on the
    question of whether senior-level presidential aides are absolutely immune to compelled
    congressional process between 2008 and the present.
    6
    Judge Bates went on to consider and reject a claim of qualified immunity for Miers, an argument that
    is not made in the instant case. 
    Miers, 558 F. Supp. 2d at 105
    .
    19
    C.     Procedural History
    Despite Miers, the Judiciary Committee and the White House found themselves
    at a subpoena-related impasse once again, when, on May 20, 2019, President Trump
    directed Don McGahn not to appear before the Judiciary Committee, as previously
    described. The Judiciary Committee filed the instant lawsuit on August 7, 2019, and it
    asserts a single cause of action: “Article I of the Constitution[.]” (Compl. at 52.) Just
    as in Miers, the Committee in the instant case claims that “[t]here is no lawful basis for
    McGahn’s refusal to appear before the Judiciary Committee” (id. ¶ 110); that he
    “enjoys no absolute immunity from appearing before the Judiciary Committee” (id.
    ¶ 111); and that “McGahn has violated . . . his legal obligations by refusing to appear
    before the Judiciary Committee . . . [and] by refusing to answer questions where there
    has been no assertion of executive or other privilege or where executive privilege has
    been waived” (id. ¶ 113). The Committee also alleges that, with respect to McGahn’s
    testimony in particular, “[t]he President has waived executive privilege as to the
    subpoenaed testimony that relates to matters and information discussed in the [Mueller]
    Report.” (Id. ¶ 112.) As a remedy for these alleged violation, the Judiciary Committee
    specifically asks this Court to award the following declaratory and injunctive relief:
    1.     Declare that McGahn’s refusal to appear before the
    Committee in response to the subpoena issued to him was
    without legal justification;
    2.     Issue an injunction ordering McGahn to appear and testify
    forthwith before the Committee; and
    3.     Issue an injunction ordering McGahn to testify as to
    matters and information discussed in the Special
    Counsel’s Report and any other matters and information
    over which executive privilege has been waived or is not
    asserted.
    20
    (Id. at 53.)
    On August 26, 2019, almost three weeks after it filed the complaint, the
    Judiciary Committee filed a motion that requested a preliminary injunction or,
    alternatively, expedited partial summary judgment. (See Pl.’s Mot.) The parties
    subsequently agreed to have the Court treat this motion as one seeking expedited partial
    summary judgment. (See Min. Order of Sept. 3, 2019.) 7 The Judiciary Committee and
    DOJ then negotiated a schedule for the briefing of legal issues related to whether this
    Court has jurisdiction to declare that McGahn’s refusal to appear is unlawful and to
    compel him to appear before the Committee—i.e., the first two prongs of the
    Committee’s request for relief (see Def.’s Mot.; Reply in Supp. of Pl.’s Mot. and Opp’n
    to Def.’s Mot. (“Pl.’s Reply”), ECF No. 37; Reply in Supp. of Def.’s Mot. (“Def.’s
    Reply”), ECF No. 40))—and the parties also briefed the merits of the question of the
    validity of DOJ’s claim of absolute testimonial immunity. Importantly, the issue of
    whether McGahn must answer any particular question that the Judiciary Committee
    poses and/or whether executive privilege applies to the answers McGahn might be
    compelled to give with respect to questions about the Mueller Report or otherwise (i.e.,
    the third prong of the Committee’s request for relief) is not currently before this Court.
    In its motion for summary judgment, the Judiciary Committee relies heavily on
    Judge Bates’s decision in Miers, and argues that this Court has subject-matter
    jurisdiction over the claims raised in the complaint by virtue of 28 U.S.C. § 1331. (See
    Pl.’s Mem. at 33).) The Judiciary Committee also asserts that it has standing to bring
    7
    As mentioned previously, although the Judiciary Committee has named McGahn individually as the
    sole defendant in this lawsuit, DOJ is representing McGahn in the context of the instant case, and its
    arguments are made on behalf of the Executive branch.
    21
    this lawsuit (see 
    id. at 33–35),
    and that Article I of the Constitution and the Declaratory
    Judgment Act provide it with the means to vindicate its right to enforce the subpoena
    (see 
    id. at 35–36).
    The Judiciary Committee further maintains that “[t]his case is
    justiciable and appropriate for this Court’s review” even though it arises from a conflict
    between the two political branches of the federal government. (Id. at 36–37.) With
    respect to the merits of the contention that McGahn has absolute testimonial immunity,
    the Judiciary Committee argues that there is no support for such a claim anywhere in
    the caselaw (see 
    id. at 39–45),
    and that McGahn must instead appear before the
    Judiciary Committee (see 
    id. at 54).
    DOJ’s cross-motion responds that Miers was “wrongly decided” and that “[t]his
    Court should not repeat [Judge Bates’s] errors.” (Def.’s Mot. at 48.) It argues, as a
    threshold matter, that this Court lacks subject-matter jurisdiction over the Judiciary
    Committee’s complaint, both because this type of inter-branch political dispute is not
    one that courts have traditionally adjudicated in light of separation-of-power principles
    (see 
    id. at 32–33;
    see also 
    id. at 40
    (arguing that “[s]uits of this kind threaten the
    separation of powers and its system of checks and balances that has served the Nation
    well for 230 years”), and because the Judiciary Committee lacks a cognizable injury for
    standing purposes (id. at 36–37). DOJ further maintains that neither 28 U.S.C. § 1331
    nor any other statute vests this Court with statutory subject-matter jurisdiction over the
    Judiciary Committee’s complaint (see 
    id. at 43–46),
    and likewise, that no substantive
    cause of action exists that allows the Judiciary Committee to sue in federal court to
    22
    enforce its subpoena (see 
    id. at 52–56).
    8 Regarding the merits of the dispute, DOJ
    references OLC opinions and contends that the President is absolutely immune from
    providing compelled testimony to Congress. See 
    id. at 60,
    63. Moreover, as a
    derivative matter, DOJ argues that the President’s immediate advisors—whom DOJ
    calls his “alter egos”—enjoy this same absolute testimonial immunity. (See 
    id. at 64–
    66.) DOJ further maintains that current and former White House Counsels are the kinds
    of immediate advisors who are covered by this blanket immunity. (See 
    id. at 68–71.)
    This Court held a motions hearing on the parties’ cross-motions for summary
    judgment on October 31, 2019. (See Min. Entry of Oct. 31, 2019.)
    III.   LEGAL STANDARDS
    A.      Cross-Motions For Summary Judgment Under Federal Rule of Civil
    Procedure 56
    The Federal Rules of Civil Procedure provide the procedural parameters for the
    Court’s consideration of the motions that the parties have presented in this case.
    Federal Rule of Civil Procedure 56 requires a court to grant summary judgment “if the
    movant shows that there is no genuine dispute as to any material fact and the movant is
    entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). In general, this means
    that the movant must demonstrate that there are no triable issues of fact in the case,
    such that the court can determine the outcome as a matter of law. Thus, in a typical
    8
    DOJ’s brief also contends that this Court should exercise its equitable discretion to refrain from
    adjudicating this dispute based on separation-of-powers concerns, and should instead allow the inter-
    branch accommodation process to play out to its conclusion. (See Def.’s Mem. at 56–57). However, in
    response to a Notice that the Judiciary Committee filed on October 29, 2019, notifying the Court that
    the parties had reached an impasse (see ECF No. 41), DOJ expressly withdrew its accommodations
    argument (see Def.’s Resp. to Pl.’s Notice Regarding Status of Accommodation Process (“Def.’s
    Accommodation Resp.”, ECF No. 42, at 2).
    23
    case, the Rule 56 question is whether the moving party has met its burden of
    demonstrating the absence of a genuine dispute as to any material fact, or whether there
    is a genuine issue of fact that will need to be resolved at trial. See, e.g., Hoyte v.
    District of Columbia, No. 13-cv-569, 
    2019 WL 3779570
    , at *7 (D.D.C. Aug. 12, 2019)
    (denying in part cross-motions for summary judgment because there were genuine
    disputes of material fact and allowing certain claims to “proceed to trial”).
    The instant matter presents a different scenario. In this case, neither party
    suggests that there are material questions of fact that must be decided by a jury.
    Instead, it is understood and undisputed that the question of whether or not the
    Constitution empowers one of the branches of government “to act in a certain way is a
    pure question of law[.]” Ctr. for Biological Diversity v. McAleenan, No. 18-cv-0655,
    
    2019 WL 4228362
    , at *8 (D.D.C. Sept. 4, 2019) (quotation marks and citation omitted).
    In such a circumstance, this Court is not concerned about the evidence pertaining to
    facts; rather, it must review and resolve the conflict between the parties regarding their
    respective interpretations of the law. A court reviewing a question of law on cross-
    motions for summary judgment decides the legal issues presented and grants summary
    judgment to the party who, based on the court’s conclusions, is entitled to judgment as
    a matter of law.
    B.     Common Law Adherence To Precedent
    In addition to applying the Federal Rules of Civil Procedure, this Court also
    relies on a basic juridical norm that is applicable to the legal issues presented in this
    case. “Under the principles of the American system, common law jurisprudence serves
    as the source of background legal principles for judicial interpretation.” Andrew C.
    Spiropoulos, Just Not Who We Are: A Critique of Common Law Constitutionalism, 54
    24
    Vill. L. Rev. 181, 183 (2009). In this regard, it is clear beyond cavil that judges should
    “abide by former precedents, where the same points come again in litigation[.]” 1
    William Blackstone, Commentaries *69; see also Michigan v. Bay Mills Indian Cmty.,
    
    134 S. Ct. 2024
    , 2036 (2014) (noting that following precedent is “a foundation stone of
    the rule of law”).
    This “rule of adherence to judicial precedents finds its expression in the doctrine
    of stare decisis[,]” which is Latin for “to stand by things decided.” Stare Decisis,
    Black’s Law Dictionary (11th ed. 2019) (quotation marks and citation omitted). This
    doctrine provides that, “‘when a point or principle of law has been once officially
    decided or settled by the ruling of a competent court in a case in which it is directly and
    necessarily involved,’” then that legal principle “‘will no longer be considered as open
    to examination or to a new ruling by the same tribunal, or by those which are bound to
    follow its adjudications, unless it be for urgent reasons and in exceptional cases.’” 
    Id. (quoting William
    M. Lile et al., Brief Making and the Use of Law Books 321 (Roger W.
    Cooley & Charles Lesley Ames eds., 3d ed. 1914)); see also Kimble v. Marvel Entm’t,
    LLC, 
    135 S. Ct. 2401
    , 2409 (2015) (explaining that, under the doctrine of stare decisis,
    “today’s Court should stand by yesterday’s decisions”). The vertical form of stare
    decisis—as between higher and lower courts within the same jurisdiction—is well
    known and generally accepted, but stare decisis also exists in horizontal form, and
    applies to courts of equal rank that are within, or outside, the same jurisdiction. See
    Richard W. Murphy, Separation of Powers and the Horizontal Force of Precedent, 78
    Notre Dame L. Rev. 1075, 1085–86 (2003). Notably, however, where a prior on-point
    precedent is not binding, stare decisis doctrine does not compel a court to follow a prior
    25
    decision that it believes erroneous; in that circumstance the later court should confront
    the prior case and “correct the error.” Gamble v. United States, 
    139 S. Ct. 1960
    , 1984
    (2019) (Thomas, J., concurring); see also Hart v. Massanari, 
    266 F.3d 1155
    , 1170 (9th
    Cir. 2001) (explaining that it would be “bad form to ignore contrary authority by failing
    even to acknowledge its existence”). And while the stare decisis doctrine is “not an
    inexorable command,” it generally is the “preferred course because it promotes the
    evenhanded, predictable, and consistent development of legal principles, fosters
    reliance on judicial decisions, and contributes to the actual and perceived integrity of
    the judicial process.” Payne v. Tennessee, 
    501 U.S. 808
    , 827–28 (1991).
    It is interesting to note that the doctrine of stare decisis performs a limiting
    function that reflects the foundational principles that undergird the federal
    government’s tripartite constitutional system. This is because deciding a legal issue
    anew each time that same question is presented, without any reference to what has been
    done before, nudges a court outside of its established domain of “say[ing] what the law
    is[,]” 
    Marbury, 5 U.S. at 177
    , and into the realm of legislating what the law should be,
    see 
    Gamble, 139 S. Ct. at 1983
    (Thomas, J., concurring) (asserting that “even common-
    law judges did not act as legislators, inserting their own preferences into the law as it
    developed”). Commentators have noted that such an unconstrained evolution in legal
    decision-making can undermine faith in the judicial system by creating the impression
    that judges are improperly enforcing their own “private sentiments” rather than working
    within a structured system in which similarly situated parties are treated similarly. 1
    William Blackstone, Commentaries *69. It might also result in the Judiciary
    improperly enhancing its own powers to the detriment of the other branches. See
    26
    
    Murphy, supra, at 1101
    (explaining that “[o]ne theme to be found in [the Framers’]
    remarks is that adherence to precedent forestalls the accumulation of arbitrary power in
    the courts—which is also a primary function of separation of powers”).
    C.     Subpoena-Related Rights, Duties, Privileges, And Immunities
    Finally, in analyzing the arguments and issues that have been presented in this
    case, this Court draws from the well-established substantive legal standards that pertain
    to subpoenas generally, both those that apply in the context of standard civil cases that
    involve the issuance of subpoenas by parties seeking information and also those that
    House committees issue in the course of congressional investigations. As it turns out, a
    general sense of such subpoena-related standards provides a helpful key to
    understanding many of this Court’s legal conclusions. For example, it is important to
    understand that subpoenas are creatures of law, that these instruments have particular
    legal significance, and that court orders are typically provided to enforce them. Such
    realizations shed substantial light on the reasons why this Court has rejected DOJ’s
    contentions regarding the subpoena dispute at bar.
    In Latin, the term “subpoena” means “under penalty.” Subpoena, Black’s Law
    Dictionary (11th ed. 2019). Simply put, a subpoena is a written mandate (also
    sometimes known as “a writ”) that creates a legally enforceable procedural obligation to
    produce or provide documents or testimony, and it does so through an appeal to some
    authoritative body’s power to sanction noncompliance. See William Mark Ormrod, The
    Origins of the Sub Pena Writ, 61 Hist. Research 11, 11, 16 (1988); see also Frederic W.
    Maitland, Equity, also, the Forms of Action at Common Law 5 (1909) (noting that the
    writ was so named “because it orders the man to appear upon pain of forfeiting a sum of
    money, e.g. subpoena centum librarum”); Oliver Wendell Holmes, Early English
    27
    Equity, 1 L. Quart. Rev. 162, 162 n.2 (1885) (noting that, at common law, the penalty
    for failing to comply with a subpoena “was usually money, but might be life and
    limb”). 9 To be properly issued, a subpoena must be imposed by an authorized person or
    entity. See Arthur R. Miller, 9A Federal Practice and Procedure § 2451 (3d ed.). In
    essence, one who has the authority to issue a subpoena possesses the right to obligate
    another person to provide testimony and/or documents—i.e., the issuer can mandate the
    performance of another with respect to the production of such information. See
    Universal Airline v. E. Air Lines, 
    188 F.2d 993
    , 999 (D.C. Cir. 1951) (explaining that
    “[t]he function of the subpoena is to compel” the production of documents or the
    provision of testimony). Moreover, because subpoenas operate by compulsion, an
    authorized issuer of a valid subpoena also has the right to enforce the production
    obligation that a subpoena creates, consistent with the law. See, e.g., Fairholme Funds,
    Inc. v. Fed. Hous. Fin. Agency, No. 13-cv-1053, 
    2019 WL 5864595
    , at *2 (D.D.C. Nov.
    8, 2019); BuzzFeed, Inc. v. U.S. Dep’t of Justice, 
    318 F. Supp. 3d 347
    , 364–65 (D.D.C.
    2018).
    9
    The historical roots of the concept of a “subpoena” go back to the times of ancient Rome and Athens.
    “[I]n the Athenian court, the witnesses who were summoned to attend the trial had their choice of three
    things: either to swear to the truth of the fact in question, to deny or abjure it, or else to pay a fine of a
    thousand drachmas.” 3 William Blackstone, Commentaries *369. Later, with respect to old English
    common law, historians have noted that “[t]he specific use of the sub pena clause in writs summoning
    men before [the Privy] council and Chancery probably . . . developed out of administrative orders used
    in the first half of the fourteenth century.” William M. Ormrod, The Origins of the Sub Pena Writ, 61
    Historical Research 11, 16 (1988). Fast forwarding a few decades, to the 1380s, the “writ of subpoena”
    was introduced by John Waltham, Chancellor to King Richard II. 3 William Blackstone, Commentaries
    *52; see also Erasmus Darwin Parker, The Origin and History of the Chancery Division, 29 L. Mag.
    Rev. 164, 170 (1904) (explaining that, before the creation of the writ of subpoena, other writs
    “threatened punishment for disobedience in indefinite terms,” but the writ of subpoena involved “the
    substitution of a definite for an indefinite penalty”). By the 1450s, “the process by bill and subpoena
    [had] become the daily practice of the court.” 3 William Blackstone, Commentaries *53; see also 
    id. at *369
    (noting that “[t]his compulsory process, to bring in unwilling witnesses, and the additional terrors
    of an attachment in case of disobedience, [was] of excellent use in the thorough investigation of truth”).
    28
    Consequently, a valid subpoena carries with it at least two legally recognized
    rights: (1) the right to direct the performance of another with respect to the production
    of documents and testimony, and (2) the right to enforce the performance obligation
    that is so imposed. For his part, the recipient of a valid subpoena has a presumptive
    duty to perform in accordance with the subpoena’s requirements. See, e.g., GFL
    Advantage Fund, Ltd. v. Colkitt, 
    216 F.R.D. 189
    , 194–96 (D.D.C. 2003) (granting a
    motion to compel compliance with a subpoena where the material sought by the
    subpoena was not privileged and the subpoena was not overbroad or issued for improper
    purposes). These well-established rights and duties are, of course, what distinguishes a
    subpoena from the requests for voluntary production of documents, testimony, or
    tangible things that typically precede a the issuance of a subpoena.
    1.     Subpoenas In Standard Civil Actions
    In the typical civil case, an attorney acting on behalf of a party and as an officer
    of the court can secure information for use in an existing federal lawsuit by issuing a
    subpoena to the custodian of the records or to the person from whom testimony is
    sought. See Fed. R. Civ. P. 45. Although private parties ordinarily do not have the
    authority to mandate others’ performance, with respect to subpoenas the right to compel
    the recipient to provide documents and/or testimony derives from the Article III power
    of the court that is presiding over the underlying case. Indeed, the party issues its
    subpoenas in the name of the court, and typically does so after unsuccessful
    negotiations over a requested voluntary production. And, ultimately, whatever the
    status of the negotiations over the requested information, the party’s issuance of an
    enforceable subpoena triggers a legal duty on the part of the recipient to perform in
    accordance with the subpoena, by providing the requested testimony and/or materials.
    29
    These rights and duties operate as a matter of law—that is, in the ordinary
    course, without a court’s intervention—during the pretrial, preparatory phase of a civil
    case. A subpoena-enforcement legal action only becomes necessary if the recipient
    refuses to provide documents or testimony despite having received a subpoena. See
    Fed. R. Civ. P. 45(g) (authorizing a court to hold in contempt “a person who, having
    been served, fails without adequate excuse to obey the subpoena”). In that
    circumstance, under the Federal Rules of Civil Procedure, the subpoena’s issuer can file
    a separate civil lawsuit in the district court in which compliance has been mandated,
    see, e.g., Fairholme Funds, 
    2019 WL 5864595
    , at *2, and in the context of that lawsuit,
    a federal judge determines various legal issues pertaining to the enforceability of the
    subpoena and disputed scope of the required response. Common legal issues are those
    that pertain to the validity of the subpoena—e.g., whether the issuer was actually
    authorized to issue subpoenas, and whether this particular subpoena contains the
    necessary terms to give rise to an enforceable duty to perform—and also the extent of
    the recipient’s duty to respond. See, e.g., Truex v. Allstate Ins. Co., No. 05-mc-0439,
    
    2006 WL 241228
    , at *1 (D.D.C. Jan. 26, 2006) (denying an issuer’s motion to compel
    performance where the subpoena at issue was invalid); Weiss v. Mentor Corp., No. 92-
    mc-0203, 
    1992 WL 235889
    , at *2 (D.D.C. July 10, 1992) (evaluating claim of attorney
    work product privilege in the context of a motion to compel compliance with a
    subpoena).
    Significantly for present purposes, if a subpoena is valid and the recipient is not
    otherwise privileged to ignore it, then some response is due by ordinary operation of the
    law. Put another way, as explained above, a valid subpoena ordinarily gives rise to a
    30
    legally enforceable duty to perform in the requested manner. And a court order is the
    well-established mechanism for the enforcement of that obligation: if the court finds
    that the recipient has breached the duty to perform that the subpoena creates, it issues
    an order that compels the recipient to comply with the subpoena. See, e.g., In re
    Denture Cream Prod. Liab. Litig., 
    292 F.R.D. 120
    , 129 (D.D.C. 2013) (granting in part
    motion to compel compliance with a subpoena and requiring the corporations involved
    to produce business records). Moreover, in deciding whether the subpoena-enforcement
    claim at issue is properly before it, the court usually does not inquire as to whether or
    not the subpoena’s issuer had other ways to get the requested information. Rather,
    assuming that the subpoena-enforcement claim is properly before it (because a party
    with standing seeks resolution of the subpoena dispute in the correct venue with respect
    to an existing federal case), the court that is called upon to review a subpoena-
    enforcement dispute resolves the legal issues that are raised by the claims presented.
    It is also important to recognize that the question of whether or not the recipient
    of a subpoena has to disclose, or may withhold, the particular information that the
    subpoena requests is entirely distinct from the question of whether the recipient of a
    subpoena has the legally enforceable duty to perform in response to a subpoena at all.
    As a general matter, the disclosure-of-information issue will be determined by the court
    based on its assessment of whether the documentary information that the subpoena
    requests, or the answers to the particular questions that a subpoenaed witness will be
    asked, can be withheld as subject to an applicable privilege, or whether the subpoena is
    improper for other reasons, such as overbreadth or undue burden. In standard civil
    cases, common law privileges such as the attorney-client privilege, the attorney work-
    31
    product privilege, and the marital privilege are often invoked to withhold subpoenaed
    information, and the privileged information is omitted from the testimony and/or
    redacted from the documents at issue. See, e.g., BuzzFeed, 
    Inc., 318 F. Supp. 3d at 361
    –62 (assessing whether information sought by subpoena was protected by the
    federal law enforcement privilege); GFL Advantage 
    Fund, 216 F.R.D. at 194
    –95
    (evaluating whether subpoenaed materials were covered by the attorney-client
    privilege); Weiss, 
    1992 WL 235889
    , at *2 (considering a work-product privilege
    objection to producing subpoenaed materials). The Constitution establishes other
    privileges that can attach to prevent certain disclosures. See, e.g., United States Sec. &
    Exch. Comm’n v. Brown, No. 09-cv-1423, 
    2010 WL 11602637
    , at *1–2 (D.D.C. Sept.
    29, 2010) (evaluating whether production of documents would violate an individual’s
    Fifth Amendment right against self-incrimination).
    By contrast, it is relatively rare for the law to recognize an “immunity” to
    compulsory legal process—i.e., the right of the recipient of a valid subpoena to decline
    to produce any documents or provide any testimony. In effect, such an immunity is
    enormously powerful, because it operates to nullify the legal obligation to perform that
    a valid subpoena creates. The sole immunity to compulsory process that DOJ
    specifically identifies in its briefs, outside of the instant context, is the Constitution’s
    Speech and Debate Clause. (See Def’s Mot. at 68.) Article I provides that, with respect
    to “any Speech or Debate in either House,” any U.S. Senator or Representative “shall
    not be questioned in any other Place[.]” U.S. Const. art. I, § 6, cl. 1. The Supreme
    Court has interpreted this provision to immunize members of Congress and their aides
    from having to appear and to provide testimony regarding “anything generally done in a
    32
    session of the House by one of its members in relation to the business before it.”
    Gravel v. United States, 
    408 U.S. 606
    , 624 (1972) (internal quotation marks and citation
    omitted).
    2.      Legislative Subpoenas
    Legislative subpoenas that are issued by congressional committees in the course
    of investigations derive from the Article I authority of the Congress, rather than the
    Article III auspices of the federal courts. It is reasonably clear that “legislative
    subpoenas are older than our country itself[,]” Trump v. Mazars USA, LLP, 
    940 F.3d 710
    , 718 (D.C. Cir. 2019); moreover, and the power of committees of the House of
    Representatives to conduct investigations that involve issuing subpoenas to witnesses
    for documents and testimony is similarly well established, see Watkins v. United States,
    
    354 U.S. 178
    , 187–95 (1957); see also Eastland v. U. S. Servicemen’s Fund, 
    421 U.S. 491
    , 504–05 (1975); Barenblatt v. United States, 
    360 U.S. 109
    , 111–12 (1959); Quinn
    v. United States, 
    349 U.S. 155
    , 160 (1955); Sinclair v. United States, 
    279 U.S. 263
    , 291
    (1929), overruled on other grounds by United States v. Gaudin, 
    515 U.S. 506
    (1995). 10
    The duty of the recipient of a valid legislative subpoena to respond to that authorized
    call of action for the good of the country is also indisputable. In this regard, the
    Supreme Court has stated that “persons summoned as witnesses by competent authority
    have certain minimum duties and obligations which are necessary concessions to the
    public interest in the orderly operation of legislative and judicial machinery[,]” United
    10
    Even before the ratification of the Constitution in 1787, “[t]he colonial assemblies, like the House of
    Commons, very early assumed, usually without question, the right to investigate . . . [and] [t]hese
    investigations were sometimes conducted by the House itself and sometimes by committees clothed
    with authority to send for ‘persons, papers, and records.’” C. S. Potts, Power of Legislative Bodies to
    Punish for Contempt, 74 U. Pa. L. Rev. 691, 708 (1926).
    33
    States v. Bryan, 
    339 U.S. 323
    , 331 (1950), and has further noted that the Court itself
    has “often iterated the importance of this public duty, which every person within the
    jurisdiction of the Government is bound to perform when properly summoned” 
    id. Indeed, the
    Supreme Court has specifically stated, in the most direct and eloquent
    terms, that “[i]t is unquestionably the duty of all citizens to cooperate with the Congress
    in its efforts to obtain the facts needed for intelligent legislative action. It is their
    unremitting obligation to respond to subpoenas, to respect the dignity of the Congress
    and its committees and to testify fully with respect to matters within the province of
    proper investigation.” 
    Watkins, 354 U.S. at 187
    –88. Thus, for all intents and purposes,
    legislative subpoenas give rise to the same rights (i.e., the right to compel the
    performance of another and the right of enforcement) and the same duties (i.e., the
    obligation to respond in the absence of a privilege) that exist in the civil action context.
    It should come as no surprise that the rights and duties that attach when a duly
    authorized committee of Congress issues a subpoena are ordinarily reverentially
    observed, or that subpoena-backed requests for information to be provided to the House
    in the context of its Article I investigations have traditionally been respected, consistent
    with core democratic and constitutional norms. See, e.g., 
    Mazars, 940 F.3d at 721
    (noting that, in response to a legislative request for information during the investigation
    of “the Iran-Contra Affair, including the role of the President,” President Ronald
    Reagan “declined to assert executive privilege, going so far as to furnish relevant
    excerpts of his personal diaries to Congress” (internal quotation marks and citation
    omitted)); see also Letter from Tobias Lear, Sec’y to the President, to Henry Knox,
    Sec’y of War (April 4, 1792) (on file with the Library of Congress) (communicating to
    34
    Secretary Knox that he “will lay before the House of Representatives such papers, from
    [his] department, as are requested by the enclosed resolution,” which empowered a
    House committee “to inquire into the causes of the failure of the late expedition under
    Major General St. Clair . . . [and] to call for such persons, papers, and records, as may
    be necessary to assist their inquiries.”). Moreover, when disputes over congressional
    subpoenas do arise, the conflict is typically resolved through negotiations between
    House committee representatives and the person or persons to whom the subpoena is
    directed—a process commonly known as “accommodation”—and, thus, committees of
    Congress rarely have had to resort to the implementation of enforcement mechanisms.
    See 
    Mazars, 940 F.3d at 721
    (“Presidents, too, have often been the subjects of
    Congress’s legislative investigations, though fewer of these have required judicial
    intervention”); see, e.g., 
    id. at 721–22
    ( “Thanks to a last-minute compromise between
    the White House and the Senate, the courts were kept out of a dispute” over whether a
    select committee investigating “the Whitewater land deal and related matters” during
    the Clinton administration “could subpoena meeting notes taken by President Clinton’s
    former lawyer”).
    That said, enforcement comes with the territory, as explained above. It is
    generally accepted that the Legislature has at its disposal additional means of enforcing
    its subpoenas as compared to those that are available to private parties who impose
    duties to perform by issuing subpoenas in the context of civil cases. See 
    Eastland, 421 U.S. at 504
    –05. Those additional tools include the power of inherent contempt. See
    
    Watkins, 354 U.S. at 216
    (citing Anderson v. Dunn, 
    19 U.S. 204
    (1821)). “[T]he long
    dormant inherent contempt power permits Congress to rely on its own constitutional
    35
    authority to detain and imprison [one who defies a subpoena and is found in contempt]
    until the individual complies with congressional demands.” See Todd Garvey,
    Congressional Research Service, RL 34097, Congress’s Contempt Power and the
    Enforcement of Congressional Subpoenas: Law, History, Practice, and Procedure 1
    (May 12, 2017); see also 
    id. at 10
    (explaining that “[u]nder the inherent contempt
    power[,] the individual is brought before the House or Senate by the Sergeant-at-Arms,
    tried at the bar of the body, and can be imprisoned or detained in the Capitol or perhaps
    elsewhere”). Congress can also issue a contempt citation, and then certify this finding
    to the Executive branch for potential criminal prosecution. See 2 U.S.C. §§ 192, 194.
    DOJ has also traditionally accepted that a committee of Congress can rely on the
    standard enforcement mechanism that is available to others who issue valid and legally
    enforceable subpoenas: it can bring a civil action in federal court. See Response to
    Cong. Requests for Info. Regarding Decisions Made Under the Indep. Counsel Act, 
    10 Op. O.L.C. 68
    , 87 (1986) (“The most likely route for Congress to take would be to file a
    civil action seeking enforcement of the subpoena.”); see also Prosecution for Contempt
    of Congress of an Executive Branch Official Who Has Asserted a Claim of Executive
    Privilege, 
    8 Op. O.L.C. 101
    , 137 & n.36 (1984).
    Notably, on those occasions when legislative subpoena disputes have been
    brought to court, the related civil actions involve the same questions about relevance,
    subpoena validity, the allegedly privileged nature of the material requested, and the
    purported immunity of the recipient as courts consider in other cases of this kind. See,
    e.g., 
    Mazars, 940 F.3d at 732
    –40 (assessing whether legislative subpoena was valid and
    whether documents sought were relevant to the underlying congressional investigation);
    36
    Senate Select Comm. on Ethics v. Packwood, 
    845 F. Supp. 17
    , 21–23 (D.D.C. 1994)
    (evaluating whether compliance with a legislative subpoena would violate an
    individual’s Fourth and Fifth Amendment rights).
    IV.    ANALYSIS
    In this case, the fact that duly authorized committees of Congress have the power
    to issue enforceable legislative subpoenas pursuant to Congress’s authority to conduct
    oversight investigations under Article I of the Constitution is not in dispute. That is,
    DOJ does not appear to challenge the Judiciary Committee’s compulsory process power,
    as a general matter. Instead, here as in Miers, DOJ contends that, nevertheless, the
    President can selectively block any House committee’s exercise of its subpoena-related
    rights with respect to certain persons who qualify as the President’s “alter egos”—
    namely, current and former senior-level presidential aides—because, in DOJ’s view,
    such persons are absolutely immune from compelled congressional process. (See, e.g.,
    Def.’s Mot. at 64.) DOJ argues further that House committees cannot file lawsuits in
    federal court to seek enforcement of subpoenas that have been issued to aides whom the
    President has ordered not to testify (id. at 52–59), and that, in any event, the federal
    courts have no subject-matter jurisdiction to review any subpoena-enforcement action
    that a House committee files if a senior-level presidential aide does not respond as
    directed (see 
    id. at 31–52).
    Setting aside the implications of these arguments for the law that governs
    subpoenas generally 
    (see supra
    Part III.C), it is important to recognize that DOJ’s
    contentions rely on basic assumptions about the relative power of the three branches of
    the federal government under our constitutional scheme. Indeed, as DOJ describes it,
    37
    the Constitution of the United States strictly segregates the power of the federal
    government and sets its branches in perfect equipoise—i.e., the Legislature, the
    Executive, and the Judiciary are entirely distinct, completely independent, and
    unfailingly co-equal (a dynamic that DOJ calls “the separation of powers”)—and this
    constitutional construct is such a driving force behind DOJ’s legal analysis that other
    foundational tenets of the Constitution, as well as the widely accepted common law
    principles that pertain to subpoenas and subpoena enforcement, are cast aside.
    For example, notwithstanding the background fact that federal courts routinely
    adjudicate subpoena-related disputes in the context of civil actions, DOJ vigorously
    asserts that federal courts lack subject-matter jurisdiction to adjudicate subpoena-
    related disputes that arise between Congress and the Executive branch. (See Hr’g Tr. at
    75:17–18 (DOJ counsel asserting that the federal courts “absolutely have th[e] authority
    [to say what the law is] in any case or controversy under Article III” but “[t]his just
    isn’t one”).) DOJ also insists that, despite the fact that ordinary citizens bring
    subpoena-enforcement claims in the federal courts all the time, duly authorized
    committees of the House of Representatives cannot proceed against the Executive
    branch in court to seek enforcement of subpoenas for testimony and information issued
    to recalcitrant government officials in the context of congressional investigations. (See
    
    id. at 74:5–7
    (“I’m making the argument that the Constitution does not allow . . . the
    House and the Executive Branch to sue each other in court[.]”).) Meanwhile, says DOJ,
    the President has the authority to make unilateral determinations regarding whether he
    and his senior-level aides (both current and former) will respond to, or defy, the
    subpoenas that authorized House committees issue during constitutionally authorized
    38
    investigations of potential wrongdoing within his administration. (See 
    id. at 125:3–6
    (counsel asserting that “if the person has testimonial immunity, and the President has
    asserted it, not the person—it’s the President’s to assert—then, yes, [Congress]
    wouldn’t be able to compel the person”). 11
    Unfortunately for DOJ, and as explained fully below, these contentions about the
    relative power of the federal courts, congressional committees, and the President distort
    established separation-of-powers principles beyond all recognition. Thus, ultimately,
    the arguments that DOJ advances to support its claim of absolute testimonial immunity
    for senior-level presidential aides transgress core constitutional truths (notwithstanding
    OLC’s persistent heralding of these and similar propositions). By contrast, textbook
    constitutional law readily reveals that, precisely because the Constitution bestows upon
    the Judiciary the power to demarcate the boundaries of lawful conduct by government
    officials, the federal courts have subject-matter jurisdiction to entertain subpoena-
    enforcement disputes concerning legislative subpoenas that have been issued to
    Executive branch officials. It is similarly well established that, because the
    Constitution vests the Legislature with the power to investigate potential abuses of
    official authority—when necessary to hold government officials (up to, and including,
    the President) accountable, as representatives of the People of the United States—then
    House committees have both Article III standing and a cause of action to pursue judicial
    enforcement of their duly authorized and legally enforceable requests for information.
    What is missing from the Constitution’s framework as the Framers envisioned it is the

    For a similar vantagepoint, see the circumstances described by George Orwell in the acclaimed book
    Animal Farm. See George Orwell, Animal Farm 141 (Otbe Book Publishing 2018) (“All animals are
    equal but some animals are more equal than others.”) (capitalization altered).
    39
    President’s purported power to kneecap House investigations of Executive branch
    operations by demanding that his senior-level aides breach their legal duty to respond to
    compelled congressional process.
    Luckily for this Court, an existing precedent that is on all fours with the instant
    matter (Miers) already systematically dismantles the edifice that DOJ appears to have
    erected over the years to enshrine the proposition that a President’s senior-level aides
    have absolute immunity with respect to legislative subpoenas that Congress issues in
    the course of its investigations; Miers does this by squarely refuting each of the
    threshold and merits arguments that DOJ seeks to advance in the instant case. This
    Court finds Miers’s analysis compelling (albeit, admittedly, not controlling) and,
    consistent with stare decisis principles, the Court adopts Judge Bates’s precedential
    reasoning herein, where referenced in the discussion below. Consequently, the Court
    cannot accept DOJ’s present reliance on carefully curated rhetoric concerning historical
    accommodations practices. Nor can it abide DOJ’s less-than-subtle suggestion that,
    under our constitutional scheme, the Legislature and the Judiciary are both hopelessly
    stymied when it comes to addressing alleged abuses by the Executive branch, such that,
    ultimately, the President wields virtually unchecked power.
    Instead, with deference to the Supreme Court’s foundational pronouncements of
    law concerning the intended intersectionality of our separate and co-equal branches of
    government, see, e.g., INS v. Chada, 
    462 U.S. 919
    , 951 (1983); Youngstown Sheet &
    Tube Co. v. Sawyer, 
    343 U.S. 579
    , 635 (1952) (Jackson, J., concurring); 
    Marbury, 5 U.S. at 176
    –77, this Court reiterates Miers’s well-sourced and thoroughly explained
    bottom-line conclusion: that, as a matter of law, senior-level current and former
    40
    presidential aides, including White House Counsels, must appear before Congress if
    compelled by legislative process to do so. This means that such aides cannot defy a
    congressional subpoena on the basis of absolute testimonial immunity, even if the
    President for whom they work (or worked) demands that response.
    A.     Federal Courts Have The Power To Adjudicate Subpoena-Related
    Disputes Between Congress And The Executive Branch
    In the Miers case, DOJ “concede[d]” that “28 U.S.C. § 1331 provides subject
    matter jurisdiction” over the Judiciary Committee’s subpoena-enforcement lawsuit, a
    conclusion with which Judge Bates agreed. 
    Miers, 558 F. Supp. 2d at 64
    . Miers also
    rejected DOJ’s jurisdictional claim that “this dispute is not one traditionally thought to
    be amenable to judicial resolution[,]” 
    id. at 67,
    and that, therefore, the House’s
    subpoena-enforcement claim should not be permitted to proceed, 
    id. at 71–73.
    In this
    regard, the Miers opinion stands for the proposition that courts have federal question
    jurisdiction over subpoena enforcement disputes between the Legislature and the
    Executive branch, and that such disputes are justiciable, regardless of the fact that the
    other two branches of government occupy places on the opposite side of the “v” in the
    case caption. This Court agrees with Miers’s analysis and conclusions for the reasons
    that follow in this section of this Memorandum Opinion, as well as those in Part IV.B.
    1.     Federal Courts Routinely Exercise Subject-Matter Jurisdiction Over
    Subpoena-Enforcement Claims Under 28 U.S.C. § 1331
    Federal courts are courts of limited jurisdiction, see Spokeo, Inc. v. Robins, 
    136 S. Ct. 1540
    , 1547 (2016), which means that their power to adjudicate legal disputes
    must be affirmatively established by law. As a general matter, under section 1331 of
    Title 28 of the United States Code, federal courts have statutory authority to entertain
    legal claims that arise under the Constitution and the laws of the United States. See
    41
    Arbaugh v. Y&H Corp., 
    546 U.S. 500
    , 513 (2006) (explaining that “[a] plaintiff
    properly invokes § 1331 jurisdiction when she pleads a colorable claim ‘arising under’
    the Constitution or laws of the United States”) (citation omitted). Miers reasoned that a
    claim by the Judiciary Committee that an Executive branch official “failed to comply
    with duly issued congressional subpoenas” fits this category, because the House
    “subpoena power derives implicitly from Article I of the Constitution[.]” Miers, 558 F.
    Supp. 2d at 64. Judge Bates also observed that the D.C. Circuit had addressed the
    question of the federal courts’ statutory subject-matter jurisdiction with respect to a
    controversy similar to the one at issue in the Miers case (and here): a dispute over a
    House committee’s issuance of a subpoena to AT & T concerning certain documents
    that the company possessed in relation to an FBI wiretapping program. The Circuit had
    conclusively determined that the federal courts have jurisdiction under 28 U.S.C.
    § 1331 because of the “fundamental constitutional rights involved[,]” AT & T 
    I, 551 F.2d at 389
    , which was enough for Judge Bates to conclude that claims that the
    Judiciary Committee made in the Miers case “arise[] under the Constitution for
    purposes of § 1331[,]” 
    Miers, 558 F. Supp. 2d at 64
    .
    This conclusion is not at all surprising. Indeed, if electronic searches of popular
    case databases are any guide, the power of the federal courts to review and resolve
    subpoena-enforcement claims in standard civil actions is rarely challenged, and federal
    courts routinely exercise subject-matter jurisdiction over disputes concerning subpoenas
    that arise in the context of cases in which federal claims are being litigated. See, e.g.,
    Fairholme Funds, 
    2019 WL 5864595
    , at *2; BuzzFeed, 
    Inc., 318 F. Supp. 3d at 364
    –65;
    Truex, 
    2006 WL 241228
    , at *1; GFL Advantage 
    Fund, 216 F.R.D. at 194
    –96; Weiss,
    42
    
    1992 WL 235889
    , at *2; see also Fed. R. Civ. P. 45. Thus, Courts appear to have
    determined that these miscellaneous lawsuits that are filed for the purpose of seeking a
    court order to enforce a subpoena, arise under federal law for the purpose of section
    1331 where the underlying case is, itself, federal in nature. The Court concludes that
    this same analysis concerning the applicability of section 1331 to the legal claim at
    issue applies here. Thus, insofar as the Judiciary Committee’s power to issue
    subpoenas “derives implicitly from Article I of the Constitution,” Miers, 
    558 F. Supp. 2d
    at 64, which it appears that DOJ does not contest, the subpoena-enforcement claim
    that the Judiciary Committee has brought to this Court for resolution likewise arises
    under the Constitution for the purpose of section 1331.
    As a reminder, DOJ conceded as much in the matter before Judge Bates. It
    retreats from that concession now, however, and launches an attack on this Court’s
    statutory subject-matter jurisdiction, by deflecting attention away from the well-
    accepted scope of a federal court’s authority under 28 U.S.C. § 1331 and homing in on
    another statutory provision: 28 U.S.C. § 1365. Pointing to that statute, DOJ maintains
    that the federal courts do not, in fact, have statutory subject-matter jurisdiction to
    entertain subpoena-enforcement claims brought by committees of the House. (See
    Def.’s Mot. at 45–46 (asserting that section 1365 establishes federal court “jurisdiction
    over some congressional subpoena-enforcement actions [i.e., those brought by the
    Senate] but not others [i.e., those brought by the House]”).) It is interesting to note that
    DOJ appears to have rejected OLC’s internal advice about the viability of this legal
    argument, for it presses this jurisdictional contention here despite the fact that,
    according to OLC, “[t]he legislative history of these statutes . . . counsels against th[e]
    43
    conclusion” that section 1365 impacts the jurisdiction of federal courts to entertain
    subpoena-enforcement lawsuits that involve subpoenas issued to Executive branch
    officials. Response to Cong. Requests for Info., 
    10 Op. O.L.C. 68
    , 87 n.31 (1986).
    Regardless, another precedential opinion from this district (which concerned
    whether a different House committee could sue to enforce a legislative subpoena for
    documents that it had issued to the Attorney General) addressed precisely the same
    statutory jurisdictional argument that DOJ brings here, and unequivocally rejected it.
    See Holder, 
    979 F. Supp. 2d 1
    . In Holder, Judge Amy Berman Jackson first noted that
    section 1365, on its face, did not apply to the dispute before it. See 
    id. at 17
    (explaining that “section 1365 specifically states that it does not have anything to do
    with cases involving a legislative effort to enforce a subpoena against an official of the
    executive branch withholding records on the grounds of a governmental privilege”).
    She then went on to thoroughly evaluate the “chronology of events surrounding the
    enactment of section 1365” and ultimately concluded that “the jurisdictional gap that it
    was meant to cure was not a lack of jurisdiction over actions like this one” but rather
    problems related to the amount-in-controversy requirements for federal jurisdiction that
    were in place in the 1970s, which were first identified in a case involving enforcement
    of a Watergate Senate subpoena, Senate Select Committee on Presidential Campaign
    Activities v. Nixon, 
    366 F. Supp. 51
    (D.D.C. 1973), and follow-on issues related to
    jurisdiction over suits against officers brought in their personal versus official
    capacities, Holder, 
    979 F. Supp. 2d
    . at 18–19; see also 
    id. (explaining that
    the
    legislative history indicates that the language of section 1365 “‘is not intended to be a
    Congressional finding that the Federal courts do not now have the authority to hear a
    44
    civil action to enforce a subpoena against an officer or employee of the Federal
    government’” (alteration omitted) (quoting S. Rep. No. 95-170, at 91–92 (1977));
    Response to Cong. Requests for Info. Regarding Decisions Made Under the Indep.
    Counsel 
    Act, 10 Op. O.L.C. at 87
    n.31 (noting the same legislative history as support
    for its conclusion the Legislature likely can enforce subpoenas against Executive branch
    officials through a civil action).
    This Court agrees with Judge Berman Jackson’s analysis in this regard, and sees
    no reason to reach a contrary conclusion. Indeed, “redundancies across statutes[,]”
    jurisdictional or otherwise, “are not unusual events in drafting[,]” and the Supreme
    Court has commanded that, in such circumstances, a court “must give effect to both”
    provisions provided that “there is no ‘positive repugnancy’ between the two laws[.]”
    Conn. Nat’l Bank v. Germain, 
    503 U.S. 249
    , 253 (1992) (quoting Wood v. United
    States, 
    16 Pet. 342
    , 363 (1842)). Indeed, courts must be cautious when evaluating an
    argument that a subsequently enacted statute, by implication and overlap, limits the
    scope of jurisdiction that section 1331 confers, Mims v. Arrow Financial Servs., LLC,
    
    565 U.S. 368
    , 383 (2012), particularly because Congress is well-aware of how to
    expressly strip jurisdiction from federal courts, see EEOC v. Lutheran Social Servs.,
    
    186 F.3d 959
    , 963 (D.C. Cir. 1999); I.A.M. Nat. Pension Fund Ben. Plan C. v. Stockton
    TRI Indus., 
    727 F.2d 1204
    , 1209 (D.C. Cir. 1984). This Court’s adoption of holdings of
    Miers and Holder is sufficient to explain why the Court rejects DOJ’s statutory subject-
    matter arguments in this case.
    45
    2.      Separation-Of-Powers Principles Do Not Compel The Conclusion
    That This Court Lacks Subject-Matter Jurisdiction Over The Instant
    Dispute
    DOJ’s primary reason for insisting that the federal courts lack subject-matter
    jurisdiction to review the Judiciary Committee’s subpoena-enforcement claim relates to
    its views of the Constitution’s limits on the exercise of judicial authority. In its briefs,
    DOJ asserts repeatedly, in various ways and at different points, that it is the
    Constitution’s separation-of-powers principles that preclude this Court’s consideration
    of the instant subpoena-enforcement lawsuit. (See, e.g., Def.’s Mot. at 18–23.) And
    while it is difficult to ferret out the differences between the various separation-of-
    powers-related arguments that DOJ makes in this regard, it appears that this battle is
    being waged on two related fronts. First of all, DOJ insists that “[t]his dispute is not of
    the type traditionally thought capable of resolution through the judicial process[.]”
    (Def.’s Mot. at 32 (capitalization altered).) It further maintains that “[l]awsuits of this
    kind imperil the Constitution’s allocation of power among the Branches of the Federal
    Government.” (Id. at 40.) 12
    Boiled to bare essence, and much like the absolute testimonial immunity claim
    that DOJ makes with respect to the merits of the Judiciary Committee’s case, these
    threshold contentions about the limited scope of the Judiciary’s power to hear the claim
    12
    In its opposition and cross-motion brief (ECF No. 32), DOJ also argues that, even if Article III’s
    prerequisites to the Court’s subject-matter jurisdiction and the Judiciary Committee’s standing are
    satisfied, a federal court should “stay its hand” with respect to resolving disputes between the
    Legislature and the Executive branch over congressional subpoenas, due to “the acute separation-of-
    powers concerns presented by judicial intervention in political disputes between the elected branches.”
    (Id. at 56.) As noted previously, DOJ has expressly withdrawn this argument by Notice (see Def.’s
    Accommodation Resp. at 2), conceding that the parties are now at an impasse over whether or not
    McGahn has a legal duty to appear before the Judiciary Committee for testimony (id.). Therefore, this
    Court has not reached, or ruled upon, the “accommodations” species of DOJ’s separation-of-powers
    argument.
    46
    at issue under the Constitution are based on “the Executive’s interest in ‘autonomy[,]’”
    Miers, 
    558 F. Supp. 2d
    at 103, and that interest, in turn, “rests upon a discredited notion
    of executive power and privilege[,]” 
    id., as explained
    below. Consequently, none of
    DOJ’s purported constitutional concerns about the exercise of jurisdiction by the
    federal courts under the circumstances presented here is persuasive.
    a.     The legal claim at issue here is not non-justiciable
    The first of DOJ’s assertions has the subtle overtones of a justiciability
    argument. For example, DOJ suggests that what is at issue when the other two branches
    of government look to the Judiciary to resolve inter-branch disputes over the
    enforceability of a subpoena is a “‘political turf war’” (Def.’s Mot. at 32 (quoting U.S.
    House of Representatives v. Mnuchin, 
    379 F. Supp. 3d 8
    , 10 (D.D.C. 2019)), and that
    “to preserve the independence and autonomy of all three co-equal branches, the
    political branches must do battle in the political arena, not appeal to the Judiciary as a
    superior branch of government for a definitive resolution” (Def.’s Mot. at 32; see also
    
    id. at 35
    (noting that, “even outside the context of disputes between the political
    Branches, the House itself has questioned whether its demands for information are ever
    justiciable”); 
    id. at 41
    (arguing that “[t]he process of negotiation and accommodation
    protects the political branches from excessive judicial interference and the Judiciary
    from the undue politicization and risk to its long-term independence”)). Whatever the
    scope or scale of the other inter-branch disputes that DOJ is referencing with this
    argument, this assertion is plainly misplaced with respect to the instant action, since, as
    noted above, a subpoena-enforcement dispute is not a “political” battle at all. Instead,
    claims regarding the enforceability of a subpoena raise garden-variety legal questions
    47
    that the federal courts address routinely and are well-equipped to handle. See Miers,
    
    558 F. Supp. 2d
    at 71.
    Consider the particular claim that the Judiciary Committee makes in the instant
    action. Its complaint specifically alleges that, in the course of a congressional
    investigation, the Committee issued a duly authorized legislative subpoena to former
    White House Counsel Donald F. McGahn II pursuant to its Article I powers (Compl.
    ¶ 72), and that “[t]here is no lawful basis for McGahn’s refusal to appear” (id. ¶ 110).
    Thus, the Judiciary Committee’s pleading presents pure questions of law for the Court’s
    resolution: in essence, the Committee is asking this Court to determine what the law
    establishes with respect to its right to compel McGahn’s testimony per the subpoena it
    has issued, and also what the law says about his duty to respond, as the recipient of the
    Committee’s directive. There is nothing non-justiciable about such legal questions.
    Indeed, federal courts across the country address these very inquiries in the context of
    enforcement actions involving private parties all the time. 
    (See supra
    Part III.C.1.)
    DOJ’s talk of “political turf war[s]” and its soaring protestations about the Committee’s
    claim being not “capable of judicial resolution” (Def.’s Mot. at 32–33) obscure the fact
    that issues such as whether a particular subpoena is valid and enforceable, and whether
    and to what extent the recipient of such a subpoena has a legal duty to respond, are
    straightforward, fully justiciable questions of law. See Miers, 
    558 F. Supp. 2d
    at 71.
    Notably, the mere fact that a committee of Congress, as opposed to some other
    litigant, has brought the instant subpoena-enforcement claim at bar has nothing
    whatsoever to do with whether this Court has subject-matter jurisdiction to entertain it.
    In general, federal courts assess their subject-matter jurisdiction on the basis of the
    48
    claims that are presented, not on the identity of the parties. See Freedom from Religion
    Found., Inc. v. Geithner, 
    644 F.3d 836
    , 844 (9th Cir. 2011) (“[I]n federal-question
    cases, the identity of the parties is irrelevant and the district court’s jurisdiction is
    grounded in the federal question(s) raised by the plaintiff.”); Teamsters, Chauffeurs,
    Warehousemen & Helpers, Local 764 v. Greenawalt, 
    880 F. Supp. 1076
    , 1081 (M.D.
    Pa. 1995) (“Rarely, if ever, does the existence or non-existence of federal question
    jurisdiction turn on the identity of the parties to the lawsuit.”). And the Supreme Court
    has specifically confirmed that not all legal claims that impact the political branches are
    properly deemed non-justiciable political questions. See, e.g., Zivotofsky ex rel.
    Zivotofsky v. Clinton, 
    566 U.S. 189
    , 196 (2012) (explaining that, although the legal
    claim at issue implicated the political status of Jerusalem as the capital of Israel,
    “Zivotofsky requests that the courts enforce a specific statutory right. To resolve his
    claim, the Judiciary must decide if Zivotofsky’s interpretation of the statute is correct,
    and whether the statute is constitutional. This is a familiar judicial exercise.”); see also
    
    Chada, 462 U.S. at 942
    (explaining that “the presence of constitutional issues with
    significant political overtones does not automatically invoke the political question
    doctrine” and that “[r]esolution of litigation challenging the constitutional authority of
    one of the three branches cannot be evaded by the courts because the issue have
    political implications”). Put another way, for the purpose of evaluating subject-matter
    jurisdiction, standard legal claims do not automatically transform into non-justiciable
    policy decisions just because they concern a political entity.
    The veritable death-knell with respect to DOJ’s present non-justiciability
    suggestions is the D.C. Circuit’s jurisdictional analysis in AT & T I, a case that
    49
    involved a “clash of the powers of the legislative and executive branches of the United
    States” under circumstances that are not dissimilar to the subpoena-enforcement
    conflict at issue here. 13 AT & T 
    I, 551 F.2d at 389
    . The D.C. Circuit specifically
    acknowledged that, like one of the Watergate cases that had proceeded it, the lawsuit
    “present[ed] a clash of congressional subpoena power and executive privilege.” 
    Id. at 390
    (referencing Senate Select Committee on Presidential Campaign Activities v. Nixon,
    
    498 F.2d 725
    (D.C. Cir. 1974) and United States v. Nixon, 
    418 U.S. 683
    (1974)). The
    panel nonetheless determined that the federal courts have subject-matter jurisdiction
    over the conflict under 28 U.S.C. § 1331, and it also expressly noted that the issue
    presented in the case—i.e., the enforceability of a House subcommittee’s subpoena
    seeking certain documents relating to a warrantless wiretapping program—was a fully
    justiciable one. 
    Id. at 389–91.
    Significantly for present purposes, the Circuit observed
    that, “at a minimum, the mere fact that there is a conflict between the legislative and
    executive branches over a congressional subpoena does not preclude judicial resolution
    of the conflict. United States v. Nixon . . . resolved an analogous conflict between the
    executive and judicial branches and stands for the justiciability of such a case.” 
    Id. at 390
    (citing United States v. Nixon, 
    418 U.S. 683
    ). In the wake of the AT & T I
    decision, DOJ’s insistence that the instant dispute over the enforceability of the House’s
    legislative subpoena is not of the type of claim that the federal courts can resolve
    13
    In AT & T I, a House subcommittee had issued a legislative subpoena to a private entity (AT & T)
    demanding documents that concerned warrantless wiretapping that the company had undertaken at the
    request of the FBI. 
    See 551 F.2d at 385
    . The Executive branch interceded by directing AT & T—“as
    an agent of the United States”—to refuse to comply with the subpoena. 
    Id. at 387.
    When it appeared
    that AT & T would, in fact, comply despite this command from the President, DOJ filed suit against AT
    & T, and the chairman of the House subcommittee that issued the subpoena was permitted to intervene
    as a defendant. 
    Id. 50 without
    doing violence to the Constitution (Def.’s Mot. at 32–33) cannot be
    sustained. 14
    b.      The historical record indicates that the Judiciary has long
    entertained subpoena-enforcement actions concerning
    compelled congressional process
    Pivoting to the second variation of their separation-of-powers argument, DOJ
    calls upon history and asserts that “centuries of historical practice” (id. at 32) plainly
    demonstrates that the U.S. Constitution does not contemplate that the federal courts
    have the power to exercise jurisdiction over subpoena-related disputes between the
    Congress and the Executive branch. (See 
    id. at 33
    (interpreting Raines v. Byrd, 
    521 U.S. 811
    (1997), as having established that “[t]he fact that past Congresses never
    resorted to the courts to resolve these and other inter-branch disputes underscored that
    the suit was not one traditionally thought to be capable of resolution through the
    judicial process.” (internal quotation marks omitted)).) While it appears to be true that
    “for two hundred years after the Founding” lawsuits between the Congress and the
    Executive branch “did not exist, even though disputes between the Legislative and
    Executive Branches over congressional requests for information have arisen since the
    beginning of the Republic” (
    id. at 33
    ), the jurisdictional lesson that DOJ appears to
    14
    DOJ’s effort to minimize the impact of the D.C. Circuit’s holding in this regard is unpersuasive.
    (See Tr. at 50:12–16 (“[T]o the extent that [AT & T I] addresses jurisdiction, it’s in a drive-by. And the
    Supreme Court has said many times that courts are not bound by drive-by jurisdictional holdings. So I
    don’t think AT & T is in any sense binding on the jurisdictional question.”). AT & T’s jurisdictional
    and justiciability pronouncements are not drive-by rulings by any stretch of the imagination; indeed,
    the D.C. Circuit sua sponte raised the issue of jurisdiction under section 1331. See 
    id. at n.7
    (“We are
    aware that 28 U.S.C. § 1331 was not alleged as the basis for jurisdiction. Although Fed. R. Civ. P.
    8(a)(1) requires plaintiffs to make an allegation of the basis asserted for the district court's jurisdiction,
    courts are not restricted to the statutory basis alleged if the factual allegations fairly support an
    alternative basis in a more proper or simple manner.”). Thus, unless and until that case is overturned, it
    is binding precedent in this Circuit. 
    (See supra
    Part III.B.)
    51
    have learned from the historical record seems to be at odds with the Supreme Court’s
    own recounting of the relevant facts.
    In the case of Watkins v. United States, 
    354 U.S. 178
    (1957), Chief Justice Earl
    Warren tells a detailed and remarkable story of the legislative power of inquiry as it
    existed in seventeenth century England, and in particular, of Parliament’s “broad and
    varied use of the contempt power” to enforce its own mandates, as well as its
    reservation unto itself of “absolute and plenary authority over . . . privileges[,]” 
    id. at 188.
    Fatefully, and importantly, the Houses of Parliament expressly decided that
    “judicial review of the exercise of the contempt power or the assertion of privilege”
    would be “precluded[,]” 
    id. at 188.
    And apparently as a direct consequence of
    Parliament’s determination “that no court had jurisdiction to consider such questions[,]”
    the unreviewable contempt power that Parliament had claimed was, predictably,
    “abused.” 
    Id. at 188,
    189.
    Significantly for present purposes, Chief Justice Warren takes care to emphasize
    that, “[i]n the early days of the United States, there lingered direct knowledge of the
    evil effects of absolute power[,]” 
    id. at 192,
    and thus, “[f]rom the very outset the use of
    contempt power by the legislature was deemed subject to judicial review[,]” 
    id. (emphasis added).
    This is a much different narrative about the historical understanding
    of the ability of the courts to entertain claims concerning the enforceability of a
    legislative subpoena than DOJ offers here. And the Court’s acknowledgement that
    DOJ’s particular argument is that the federal courts do not have subject-matter
    jurisdiction to adjudicate a dispute over a legislative subpoena at Congress’ behest, and
    that it has not made direct representations about whether the federal courts historically
    52
    entertained claims that private citizens brought to challenge compelled congressional
    process, does not diminish that divergence. Regardless, the historical record plainly
    reflects that, since the Revolution, judicial review has been available to ensure that the
    use of compulsory congressional process and/or the invocation of a privilege with
    respect to compelled performance is consistent with the law. See 
    id. at 193–94
    (discussing Kilbourne v. Thompson, 
    103 U.S. 168
    (1881), in which the Supreme Court
    found, in 1881, that “the House had . . . exceeded the limits of its own authority” when
    it initiated an inquiry that was judicial, and not legislative, in nature); see also 
    Mazars, 940 F.3d at 718
    –21 (describing at length a series of cases throughout history in which
    the Supreme Court adjudicated challenges to legislative subpoenas issued by Congress).
    Watkins also touched upon the fact that the Supreme Court had previously considered
    the competing interests of the Executive and the Legislature with respect to subpoenas
    pertaining to legislative investigations, and had suggested caution with respect to the
    merits of claims that the Congress had overstepped its bounds, given “the danger to
    effective and honest conduct of the Government if the legislature’s power to probe
    corruption in the executive branch were unduly hampered.” 
    Id. at 194–95
    (first citing
    
    McGrain, 273 U.S. at 194
    –95, and then 
    Sinclair, 279 U.S. at 263
    ). This, too, indicates
    that the Supreme Court’s primary concern about the exercise of judicial authority was
    that judges might be too aggressive concerning the remedies they ordered with respect
    to adjudicating challenges to compelled congressional process, not that the federal
    courts lacked the authority to even entertain such claims.
    Consequently, DOJ’s present suggestion that the history of our constitutional
    Republic simply does not contemplate that the other branches of government would
    53
    enlist the Judiciary to resolve disputes over the scope of compelled congressional
    process in the context of legislative investigations—and thus that a federal court
    oversteps its bounds if it exercises subject-matter jurisdiction over a claim like the one
    the Judiciary Committee brings here (see Def.’s Mot. at 32–36)—seems inconsistent
    with Watkins’s clear assessment that the federal courts of the United States have always
    had to power to review legal claims with respect to subpoena-enforcement actions, and
    once again, it is well established that subject-matter jurisdiction generally turns on the
    legal claim being asserted regardless of who makes it. Indeed, the Watkins Court
    specifically noted that federal courts possess a “responsibility placed by the
    Constitution upon the judiciary to insure that the Congress does not unjustifiably
    encroach upon an individual’s right to privacy nor abridge his liberty of speech, press,
    religion or assembly[,]” 
    id. at 198–99,
    while at the same time, they must take care to
    provide “ample scope . . . to the Congress as the sole constitutional depository of
    legislative power[,]” 
    id. at 215;
    see also, e.g., 
    id. at 216.
    And DOJ does not, and
    apparently cannot, explain why this constitutional duty disappears, or is neutralized, if
    the subpoena-related dispute arises between branches of government, rather than
    between Congress and an individual party who contends that the Legislature’s
    compelled congressional process is unlawful.
    Watkins also seems to explain the dearth of cases during the two-century period
    in which DOJ says that lawsuits concerning “Congress’ access to information held by
    the Executive Branch . . . did not exist[.]” (Def.’s Mot. at 33.) DOJ lays out a
    chronology of recorded conflicts between Presidents and the House of Representatives
    with respect to Congress’s access to information between 1792 and 2008 (see Def.’s
    54
    Mot. at 33–35), and because “for nearly two hundred years the Legislative Branch never
    sought to invoke the power of the Judiciary to decide which side should prevail in a
    political battle with the Executive” concerning congressional requests for information
    (
    id. at 35
    ), DOJ implies that courts must have had the view that their power to
    adjudicate legal disputes between the branches was unauthorized. It might well be so
    that courts were not engaged in resolving such conflicts. But Watkins suggests a
    different implication: Congress “so sparingly employed the power to conduct
    investigations, . . . [that] there [were] few cases requiring judicial review of the
    power.” 
    Watkins, 354 U.S. at 193
    (emphasis added).
    To be sure, there was an uptick in Congress’ use of its investigative power in the
    late nineteenth century, and yet, as DOJ emphasizes, “there were [still] very few cases
    dealing with the investigative power.” 
    Id. at 194.
    But that dearth of court decisions
    hardly establishes that “zero-sum litigation in federal court” had been categorically
    ruled out as a matter of constitutional law, as DOJ suggests. (Def.’s Mot. at 36.) It is
    just as logical, and perhaps even more so, to conclude that the Executive branch
    understood from prior case law the slim odds of successfully resisting the primary tool
    that the Congress had to check its abuses—a subpoena issued in the context of an
    authorized investigation—if its challenges were litigated in federal court, and thus, it
    routinely consented to negotiate the terms of its performance. As the Supreme Court
    suggested in Watkins, even early on in the history of our Nation, there were “several
    basic premises on which there [was] general agreement” including the fact that “[t]he
    power of the Congress to conduct investigations is inherent in the legislative process”
    and that “[t]hat power is broad.” 
    Watkins, 354 U.S. at 187
    . Moreover, it was
    55
    uncontroversial that Congress’s investigatory authority “encompasses inquiries
    concerning the administration of existing laws as well as proposed or possibly needed
    statutes”; that “[i]t includes surveys of defects in our social, economic or political
    system for the purpose of enabling the Congress to remedy them”; and that it also
    “comprehends probes into departments of the Federal Government to expose corruption,
    inefficiency or waste.” 
    Id. Thus, rather
    than shedding light on the accepted scope of
    the federal courts’ authority to resolve inter-branch disputes over compelled
    congressional process, the absence of recorded federal cases concerning the myriad
    “clashes between the two political Branches over congressional attempts to obtain
    testimony” that DOJ’s brief identifies (Def.’s Mot. at 34) better supports the far less
    sensational conclusion that, with respect to legislative subpoena fights, the Executive
    branch wisely picked its battles.
    Consequently, and somewhat ironically, DOJ’s main historical assertions
    dovetail in a manner that ultimately counteracts its own conclusions. That is, “[t]he
    fact that past Congresses never resorted to the courts to resolve” to inter-branch
    disputes concerning the congressional requests for information (Def.’s Mot. at 33)
    merely means that, unlike the Judiciary Committee of today, they did not have to,
    because instead of reaching an impasse over the Executive branch’s rank refusal to
    cooperate with congressional investigations, the Executive branch’s concerns about the
    scope and intrusiveness of Congress’ requests for information were resolved through
    “the centuries-old process of political negotiation” (id. at 36). See also 
    Mazars, 940 F.3d at 721
    (explaining that “Presidents, too, have often been the subjects of Congress’s
    legislative interventions,” but, in contrast to disputes between House committees and
    56
    private-citizen recipients of legislative subpoenas, “fewer of these have required
    judicial intervention”).
    Finally, this Court notes that DOJ’s contention that the Constitution’s separation
    of powers bars the judiciary from adjudicating disputes between Congress and the
    Executive concerning the enforceability of legislative subpoenas is an argument that it
    has not consistently maintained, even in modern times. For example, a review of the
    publicly available dockets in Trump v. Committee on Ways & Means, U.S. House of
    Representatives, No. 19-cv-2173 (Nichols, J.), Trump v. Committee on Oversight &
    Reform of U.S. House of Representatives, No. 19-cv-1136 (Mehta, J.), and Trump v.
    Mazars USA, LLP, No. 19-5142 (D.C. Cir.), indicates that DOJ stood silent with respect
    to the jurisdictional question, as President Trump (in his personal capacity) has invoked
    the authority of the federal courts, on more than one occasion, seeking resolution of a
    dispute over the enforceability of a legislative subpoena concerning his tax returns. A
    lawsuit that asserts that a legislative subpoena should be quashed as unlawful is merely
    the flip side of a lawsuit that argues that a legislative subpoena should be enforced.
    And it is either DOJ’s position that the federal courts have jurisdiction to review such
    subpoena-enforcement claims or that they do not. By arguing vigorously here that the
    federal courts have no subject-matter jurisdiction to entertain the Judiciary Committee’s
    subpoena-enforcement action, yet taking no position on the jurisdictional basis for the
    President’s maintenance of lawsuits to prevent Congress from accessing his personal
    records by legislative subpoena, DOJ implicitly suggests that (much like absolute
    57
    testimonial immunity) the subject-matter jurisdiction of the federal courts is properly
    invoked only at the pleasure of the President. 15
    The fact that DOJ has also recently expressly declined to press a jurisdictional
    argument in another subpoena-enforcement case that is currently pending before the
    D.C. Circuit is instructive. See In re Application of Comm. on Judiciary, U.S. House of
    Representatives, for an Order Authorizing Release of Certain Grand Jury Materials,
    No. 19-gj-48, 
    2019 WL 5485221
    (D.D.C. Oct. 25, 2019), appeal docketed, No. 19-5288
    (D.C. Cir. Oct. 28, 2019) (hereinafter In re Application for Grand Jury Materials).
    Pending on appeal in the D.C. Circuit is a ruling concerning an application that the
    Judiciary Committee submitted to the Chief Judge of this Court, requesting that grand
    jury information in DOJ’s possession concerning the Mueller Report be released to the
    Committee, over DOJ’s objection. (The Committee had previously sent a subpoena to
    Attorney General William Barr requesting the information, but that legislative
    command was ignored.) Chief Judge Howell issued a Memorandum Opinion and Order
    granting the Committee’s request for all of the portions of the Mueller Report that had
    been redacted to preserve grand jury secrecy and any underlying transcripts or exhibits
    referenced in the redactions. 
    Id. at *38.
    DOJ proceeded to seek an emergency stay of
    Chief Judge Howell’s ruling in the D.C. Circuit. See Emergency Mot. for Stay Pending
    Appeal (“DOJ Stay Br.”), In re Application of Comm. on Judiciary, U.S. House of
    15
    To be fair, in these lawsuits, President Trump argued that the congressional committee subpoenas are
    unenforceable in his personal capacity. But when DOJ was invited file an amicus brief at the appellate
    level in Mazars, it did not raise an objection to the courts’ jurisdiction; instead, it emphasized that
    federal courts “must” determine—after a “searching evaluation”—whether the legislative subpoena
    ought to be quashed because, for instance, it is “impermissibly attempting to interfere with or harass
    the Head of the Executive Branch.” Amicus Brief of the United States at 1–2, Trump v. Mazars USA,
    LLP,

    Representatives, for an Order Authorizing Release of Certain Grand Jury Materials,
    No. 19-5288 (D.C. Cir.).
    During oral argument, when one of the panelists asked DOJ about the district
    court’s subject-matter jurisdiction to entertain the House’s legal action, DOJ counsel
    remarked that, while the Executive branch was “not advancing that argument[,]” it
    believed that DOJ “certainly has both standing and jurisdiction” to seek review of the
    district court’s injunction. Hr’g Tr. at 17:5–9, In re Application of Comm. on Judiciary,
    U.S. House of Representatives, for an Order Authorizing Release of Certain Grand Jury
    Materials, No. 19-5288 (D.C. Cir.). And, indeed, DOJ did not challenge Chief Judge
    Howell’s jurisdiction to consider the House’s application in any of its briefs or during
    any of the hearings in front of either the District Court or the Circuit. But if DOJ’s
    position is that the federal courts have the authority to entertain a legal claim
    concerning the House’s contested request for allegedly privileged grand jury materials,
    how can it be heard to argue, nearly simultaneously, that the instant Court has no
    jurisdiction to entertain a legal claim concerning the enforceability of a House
    committee’s subpoena compelling the testimony of senior-level presidential aides?
    Both of these requests for information were made by the Judiciary Committee in the
    context of ongoing investigations. Compare DOJ Stay Br. at 10, with In re Application
    for Grand Jury Materials, 
    2019 WL 5485221
    , at *28, and 
    Mazars, 940 F.3d at 714
    .
    And any differences between the instant case and the case on appeal before the Circuit
    appear to relate simply and solely to the merits of the parties’ respective legal
    arguments regarding the enforceability of the House’s mandate that the information be
    59
    disclosed. 16 Such differences have nothing to do with the threshold question of the
    court’s constitutional power to entertain the House’s legal claim that it is entitled to
    access the requested (or subpoenaed) information over the Executive branch’s
    objection; therefore, one would expect that DOJ’s jurisdictional position would not
    vary.
    c.      Traditional separation-of-powers principles do not support
    DOJ’s suggestion that the federal courts cannot resolve
    legal disputes between the other branches of government
    If the point of DOJ’s historical practice arguments is to emphasize that, for
    centuries, significant inter-branch conflicts have, in fact, been resolved without the
    need for court involvement (and thereby place its marker on the seemingly radical
    notion that the federal courts do not have the constitutional authority to resolve any
    direct dispute between the Executive and the Legislature (see, e.g., Hr’g Tr. at 60:18)),
    then DOJ must contend with, and somehow reconcile, the fact that the federal courts
    have adjudicated disputes that impact the divergent interests of the other branches of
    government for centuries. See, e.g., Ex parte Merryman, 
    17 F. Cas. 144
    , 148 (C.C.D.
    Md. 1861) (Taney, C.J.) (holding that Congress, and not the President, can suspend the
    writ of habeas corpus); see also Bowsher v. Synar, 
    478 U.S. 714
    (1986) (evaluating
    whether Congress improperly assigned executive powers to the Comptroller General);
    16
    Though the circumstances that have given rise to these two legal actions surely differ, there appear
    to be only two relevant distinctions between the legal claims that the Judiciary Committee is making in
    these two cases. In the In re Application for Grand Jury Materials litigation, the Committee’s
    purported right to the materials at issue (grand jury information) arguably derives both from its own
    Article I authority to conduct investigations pursuant to its impeachment powers, and also from the
    court’s limited authority to make exceptions to grand jury secrecy under Federal Rule of Criminal
    Procedure 6(e). See 
    2019 WL 5485221
    , at *11. Rule 6(e) is not a source of authority in the case at bar.
    In addition, the Committee’s grand jury document request concerns materials that are purportedly
    protected from disclosure under Rule 6(e), while, in the instant case, the President has invoked
    executive privilege on the grounds that McGahn has absolute testimonial immunity. Both of these
    distinctions pertain to the merits issues in these cases, not to the Court’s subject-matter jurisdiction.

    Chadha, 462 U.S. at 919
    (considering whether the House could veto an Executive
    branch deportation order); Nixon v. Sirica, 
    487 F.2d 700
    , 715 (D.C. Cir. 1973)
    (“Throughout our history, there have frequently been conflicts between independent
    organs of the federal government, as well as between the state and federal governments.
    When such conflicts arise in justiciable cases, our constitutional system provides a
    means for resolving them—one Supreme Court.”). DOJ must also face at least two
    other inconvenient facts: the widely accepted contentions that (1) the Constitution of
    the United States empowers each branch of the federal government to be a check upon
    the others, and (2) the Judiciary’s constitutional check is the power to tell the other
    branches what the law is. See 
    Chada, 462 U.S. at 962
    –63; 
    Buckley, 424 U.S. at 121
    –23;
    
    Marbury, 5 U.S. at 177
    . The Supreme Court has never suggested that the Judiciary has
    the power to perform its constitutionally assigned function only when it speaks to
    private citizens, or when it is called upon to resolve a legal dispute between a private
    citizen and one of the branches of government. And DOJ’s odd idea that federal courts’
    indisputable power to adjudicate questions of law evaporates if the requested
    pronouncement of law happens to occur in the context of a dispute between branches
    appears nowhere in the annals of established constitutional law.
    To the contrary, the Framers spoke specifically to the importance of maintaining
    an established rule of law to regulate government conduct—and, thus, to the
    significance of the judicial function—when they explained why a system that separates
    the powers of government and includes checks on the exercise of government power is
    crucial to sustaining a democracy:
    61
    [T]he great security against a gradual concentration of the several
    powers in the same department, consists in giving to those who
    administer each department the necessary constitutional means
    and personal motives to resist encroachments of the others. The
    provision for defense must in this, as in all other cases, be made
    commensurate to the danger of the attack. . . . It may be a
    reflection on human nature, that such devices should be necessary
    to control the abuses of government. But what is government
    itself, but the greatest of all reflections on human nature? If men
    were angels, no government would be necessary. If angels were
    to govern men, neither external nor internal controls on
    government would be necessary. In framing a government which
    is to be administered by men over men, the great difficulty lies
    in this: you must first enable the government to control the
    governed; and in the next place oblige it to control itself.
    The Federalist No. 51 (James Madison). The Framer’s specific reference to providing
    government officials in each of the separate branches with “the necessary constitutional
    means and personal motives to resist the encroachments of the others[,]” 
    id., is especially
    noteworthy, because, here, DOJ’s artificial limit on the federal courts’
    jurisdiction to consider disputes between the branches seemingly decreases the
    incentive for the Legislature or the Executive branch to behave lawfully, rather than
    bolsters it, by dramatically reducing the potential that a federal court will have occasion
    to declare conduct that violates the Constitution unlawful. And there can be no doubt
    that providing the branches with the power to limit each other’s behavior, for the
    protection of the People, was the original intent of the Framers, as evidenced both by
    the constitutional scheme they adopted and by the remarks they made to explain the
    separation-of-powers construct. Indeed, far from DOJ’s present suggestion that the
    separation-of-powers construct means that the political branches must resolve their
    disputes in the political arena and never head to federal court, Federalist No. 51
    proceeds to explain that political checks are not the sole solution, and that the branches
    themselves must also be vested with the power to police the abuses of the others. See
    62
    
    id. (“A dependence
    on the people is, no doubt, the primary control on the government;
    but experience has taught mankind the necessity of auxiliary precautions. . . . We see it
    particularly displayed in all the subordinate distributions of power, where the constant
    aim is to divide and arrange the several offices in such a manner as that each may be a
    check on the other that the private interest of every individual may be a sentinel over
    the public rights.”).
    Nor is it the case that the separate and co-equal stature of the three branches of
    government means that the Judiciary cannot comment on the lawfulness of other
    branches’ conduct. Cf. Ex parte 
    Merryman, 17 F. Cas. at 148
    (holding that, by
    suspending the writ of habeas corpus, “the president has exercised a power which he
    does not possess under the Constitution,” and sending the ruling to the President “in
    order that he might perform his constitutional duty, to enforce the laws, by securing
    obedience”); see also 
    Marbury, 5 U.S. at 177
    . In the seminal case of Buckley v. Valeo,
    
    424 U.S. 1
    (1976), the Supreme Court further observed that, while “the men who met in
    Philadelphia in the summer of 1787 were practical statesmen, experienced in politics,
    who viewed the separation of powers as a vital check against tyranny[,] . . . they
    likewise saw that a hermetic sealing off of the three branches of Government from one
    another would preclude the establishment of a Nation capable of governing itself
    effectively.” 
    Id. at 121;
    see also 
    Youngstown, 343 U.S. at 635
    (Jackson, J., concurring)
    (“While the Constitution diffuses power to better secure liberty, it also contemplates
    that practice will integrate the dispersed powers into a workable government. It enjoins
    upon its branches separateness but interdependence, autonomy but reciprocity.”). And
    where, as here, the Executive branch and the Legislature are at loggerheads over an
    63
    issue of law that the courts are well-equipped to decide, the notion that the Judiciary
    loses its established authority to say what the law is seems implausible. It is far more
    likely that the better view of constitutional separation-of-powers principles is that they
    deem the exercise of judicial authority with respect to the dispute at issue even more
    important, if not crucial, for the continued functioning of the government.
    To the extent that more recent case law could be read to cast doubt on this
    Court’s conclusion that the federal courts have the constitutional power to adjudicate
    legal disputes between the Legislature and the Executive branch (see Def. Mem. at 32–
    36), it is worth noting that such cases actually comport quite well with the Framers’
    conceptions of the true separation-of-powers problems discussed above. For example,
    binding case law rightly indicates that federal courts do overstep the bounds of their
    authority if they entertain a claim in a dispute between the other branches that does not
    actually involve a question of law. See 
    Zivotosfy, 132 S. Ct. at 1432
    (Sotomayor, J.,
    concurring) (explaining that judicial forbearance is required in “circumstances in which
    a dispute calls for decisionmaking beyond courts’ competence”). Likewise, there is a
    separation-of-powers violation if the Judiciary proceeds when the Constitution itself
    expressly vests the power in another branch of government to decide the issue in
    question. See 
    id. at 1431
    (“When a case would require a court to decide an issue whose
    resolution is textually committed to a coordinate political department . . . abstention is
    warranted because the court lacks authority to resolve that issue.”); see also, e.g., Nixon
    v. United States, 
    506 U.S. 224
    (1993) (holding that a claim regarding the validity of a
    Senate impeachment rule was non-justiciable because the Constitution vests the Senate
    with the sole power to try impeachments). In these narrow circumstances, the Judiciary
    64
    plainly transgresses the boundaries of its constitutional authority, either because it has
    entertained a claim that does not raise a legal issue and thus was never in its province to
    decide, or because it has undertaken to decide certain claims despite a direct
    constitutional command to desist. Neither is the case with respect to the subpoena-
    enforcement claims at issue here, as the Court’s previous discussion plainly establishes.
    
    (See supra
    Part IV.A.2.a.) 17
    The bottom line is this: even when the question of this Court’s constitutional
    authority to entertain the Judiciary Committee’s subpoena-enforcement claim is viewed
    through the rose-colored lenses of DOJ’s separation-of-powers filter, history and past
    practice plainly support judicial resolution of stalemates between the Legislature and
    the Executive branch with respect to the rights that the law establishes and the duties
    that the law imposes. The Framers carefully crafted a constitutional scheme that
    contained institutional checks over the exercise of the powers they had divided, and
    thus implicitly endorsed the exercise of authority by the branch that was vested with
    power to break a legal stalemate (and, indeed, without judicial resolution, how else
    17
    The Court finds it noteworthy that DOJ does not provide a single authority that actually stands for
    the proposition that the Constitution is violated whenever the federal courts entertain any kind of
    dispute between the Legislature and the Executive branch. (See Hr’g Tr. at 60:18.) DOJ’s argument in
    this regard appears to rely the position that the Executive branch would be inappropriately rendered
    subordinate to the other two branches of government if the Legislature can file suit against the
    Executive branch in court. (See 
    id. 68:1–10.) But
    in the absence of a case that stands for this
    proposition, it seems a better view of the Executive’s predicament is that, if anything, all of the
    branches are equal in that all are subordinate to the law, and the courts are only the messengers, to the
    extent that the Judiciary has the power to determine what the law is. See Richard H. Fallon,
    Jr., Executive Power and the Political Constitution, 
    2007 Utah L
    . Rev. 1, 17 (2007) (“[I]t is arguable
    that the power to decide cases necessarily implies the power to decide them authoritatively, and
    authority in some cases depends on executive obedience.”). To find otherwise is to flout what is
    unquestionably the most significant tenet that exists in our system of government: that each branch of
    the federal government has limited power under the Constitution, and that no one, not even the head of
    the Executive branch, is above the law. DOJ’s insistence that the Judiciary does not have the power to
    declare the law in the context of an inter-branch legal dispute cannot be easily squared with acceptance
    of these universal constitutional maxims.
    65
    would an impasse between the Legislature and Executive branch concerning compelled
    congressional process be resolved?). Thus, in this Court’s view, rather than demanding
    forbearance by the courts, separation-of-powers principles instead require the federal
    courts to proceed to resolve the instant legal impasse so that the other branches of
    government can function. Put another way, the Framers made clear that the proper
    functioning of a federal government that is consistent with the preservation of
    constitutional rights hinges just as much on the intersectionality of the branches as it
    does on their separation, and it is the assigned role of the Judiciary to exercise the
    adjudicatory power prescribed to them under the Constitution’s framework to address
    the disputed legal issues that are spawned from the resulting friction. See Myers v.
    United States, 
    272 U.S. 52
    , 293 (1926) (Brandeis, J., dissenting) (“The doctrine of the
    separation of powers was adopted by the convention of 1787 not to promote efficiency
    but to preclude the exercise of arbitrary power. The purpose was not to avoid friction,
    but, by means of the inevitable friction incident to the distribution of the governmental
    powers among three departments, to save the people from autocracy.”)
    B.     House Committees Have The Power To Enforce Their Subpoenas In
    Federal Court When Executive Branch Officials Do Not Respond As
    Required
    For all its talk about the limited authority of the Judiciary and the Legislature
    under the Constitution, DOJ does not appear to contest the fact that duly authorized
    committees of Congress have the power under Article I to issue enforceable legislative
    subpoenas—in the sense that, when a House committee issues an authorized legislative
    subpoena in the context of a congressional investigation, that act gives rise to a legal
    66
    right to compel the recipient’s performance. 18 Consequently, and importantly, the
    constitutional arguments that DOJ has made in the context of this case pertain solely to
    its view that the Judiciary Committee lacks the authority to enforce its valid legislative
    subpoenas in federal court. (See, e.g., Def.’s Mot. at 36–40, 52–56.) Here, as in Miers,
    DOJ attempts to shoehorn its emasculating effort to keep House committees from
    turning to the courts as a means of vindicating their constitutional interests into various
    categories of established legal arguments, some of which overlap substantially with
    jurisdictional contentions that the Court has already considered and rejected. (See, e.g.,
    
    id. at 36–40
    (arguing that the Judiciary Committee lacks standing because it has not
    articulated a concrete and particularized injury).)
    In the discussion that follows, this Court focuses, in particular, on DOJ’s
    contention that a House committee does not suffer a cognizable injury for standing
    purposes when a subpoenaed Executive branch official fails to appear for the scheduled
    testimony (
    id. at 36–40
    ), and that, in any event, such committee has no cause of action
    to proceed in federal court (
    id. at 52–56).
    As the Court explains, these arguments about
    the Judiciary Committee’s inability to bring its legal claims in federal court cannot be
    reconciled with how the law ordinarily assesses the type of injury that the Judiciary
    Committee alleges for standing purposes, or with the fact that filing a lawsuit is the
    most common, and least intrusive, means of vindicating the Committee’s thwarted
    investigation rights. The Court also rejects DOJ’s broader assertion that, even if the
    Judiciary Committee has an injury in fact and a cause of action to proceed in federal
    18
    Of course, any protestation would be futile, since this broad power of Congress is well established.
    See, e.g., 
    McGrain, 273 U.S. at 174
    ; 
    Mazars, 940 F.3d at 722

    court, constitutional separation-of-powers principles prevent the Committee from doing
    so.
    1.      Defiance Of A Valid Subpoena Indisputably Qualifies As A
    Cognizable Injury In Fact, And In The Context Of Congressional
    Investigations, The Harm Is Significant And Substantial
    With respect to the Judiciary Committee’s alleged lack of Article III standing to
    bring its subpoena-enforcement claims in federal court, DOJ maintains that “the
    Committee fails to state a cognizable injury[.]” (Def.’s Mot. at 36.) 19 In this regard,
    DOJ insists that the Committee’s allegation that “McGahn’s failure to comply with its
    subpoena for his testimony deprives it of ‘information to which it is entitled’” is not
    enough to give rise to Article III standing (id. at 37 (quoting Pl.’s Mem. at 22, 37)),
    because “Congress has no cognizable institutional interest in obtaining information for
    its own sake” (id.). It also asserts that, other than this non-cognizable “freestanding
    right to information[,]” the Judiciary Committee has only asserted the kinds of abstract
    injuries that the Supreme Court has found to be insufficient to support standing in cases
    like Raines v. Byrd, 
    521 U.S. 811
    (1997). (Def.’s Mot. at 37–38; see also 
    id. (declaring that
    the Judiciary Committee’s stake in the instant litigation is “deficient” for standing
    purposes because “[t]he sole injury arguably stated by the Committee is a theoretical
    impairment of the House’s ability to evaluate proposed articles of impeachment;
    19
    “Because Article III limits the constitutional role of the federal judiciary to resolving cases and
    controversies, a showing of standing is an essential and unchanging predicate to any exercise of our
    jurisdiction.” Fla. Audubon Soc. v. Bentsen, 
    94 F.3d 658
    , 663 (D.C. Cir. 1996) (en banc) (internal
    quotation marks and citations omitted); see also Gill v. Whitford, 
    138 S. Ct. 1916
    , 1929 (2018) (“To
    ensure that the Federal Judiciary respects the proper—and properly limited—role of the courts in a
    democratic society, a plaintiff may not invoke federal-court jurisdiction unless he can show a personal
    stake in the outcome of the controversy.”) (internal quotation marks and citations omitted). And one of
    the requirements to demonstrate Article III standing is that “the plaintiff must have suffered an injury
    in fact—an invasion of a legally protected interest which is (a) concrete and particularized; and (b)
    actual or imminent, not conjectural or hypothetical.” Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560
    (1992) (internal quotation marks and citations omitted).

    proposed legislation concerning election security, campaign finance, and other issues;
    and the adequacy of safeguards to protect the integrity of investigatory matters referred
    by the Special counsel to other components of the Department of Justice (a matter
    purportedly implicating the Committee’s ‘oversight’ responsibilities)” (citations
    omitted)).)
    The first puzzle that surfaces when one undertakes to assess DOJ’s “no
    cognizable injury” argument is how this contention accounts for the fact that an injury-
    in-fact for Article III standing purposes is all but assumed in the myriad subpoena-
    enforcement cases that are filed in federal courts with respect to civil actions every day.
    The harm claimed by a private litigant when his subpoenas are rebuffed, which almost
    presumptively provides a sufficient stake to support his standing, and the injury that the
    Judiciary Committee claims here is not different in kind. Yet this Court could not find
    a single case in which the concreteness or particularity of the injury alleged by a private
    subpoena issuer was effectively challenged. As far as this Court can tell, no federal
    judge has ever held that defiance of a valid subpoena does not amount to a concrete and
    particularized injury in fact; indeed, it appears that no court has ever even considered
    this proposition. And perhaps for good reason: if defiance of duly issued subpoenas
    does not create Article III standing and does not open the doors of the court for
    enforcement purposes, it is hard to see how the wheels of our system of civil and
    criminal justice could keep turning.
    Consequently, some courts have concluded that even the simple impairment of a
    prosecutor’s right to issue a subpoena in the first place is enough to cause a cognizable
    injury. See, e.g., United States v. Colo. Supreme Court, 
    87 F.3d 1161
    , 1165 (10th Cir.
    69
    1996) (finding a concrete, particularized, and actual injury where a Colorado ethics rule
    requires prosecutors to obtain judicial approval of any subpoena that seeks to compel an
    attorney to testify before a grand jury about a client); see also United States v. Supreme
    Court of N.M., 
    839 F.3d 888
    , 899 (10th Cir. 2016) (reaching the same conclusion with
    respect to similar New Mexico ethics rule), cert. denied, 
    138 S. Ct. 130
    (2017). And
    the D.C. Circuit implicitly suggested that interference with an agency’s right to compel
    compliance by subpoena is an injury that must be remedied, at least in the
    administrative context, when it held that courts “must enforce” an agency’s subpoena so
    long as “‘the inquiry is within the authority of the agency, the demand is not too
    indefinite[,] and the information sought is reasonably relevant.’” Resolution Tr. Corp.
    v. Thornton, 
    41 F.3d 1539
    , 1544 (D.C. Cir. 1994) (quoting United States v. Morton Salt
    Co., 
    338 U.S. 632
    , 652 (1950)). If the creation of hurdles to the issuance of
    prosecutorial subpoenas is a cognizable Article III injury, and if courts have no choice
    but to recognize Article III standing for those who seek to enforce reasonable
    administrative subpoenas, it would seem that the law is sufficiently clear that outright
    defiance of any duly issued subpoena, including the subpoena that the Judiciary
    Committee issued to McGahn, qualifies as a concrete, particularized, and actual injury
    for standing purposes.
    This is not to suggest an equivalence between the harm that a private litigant
    experiences when his subpoena rights are thwarted, on the one hand, and the harm
    inflicted on a committee of Congress when a recipient of a legislative subpoena that is
    issued in the context of a congressional investigation defies its mandates, on the other.
    While the nature of the injury—i.e., the denial of the right to compel performance—is
    70
    similarly actual and concrete, the Supreme Court has suggested that the degree of harm
    is an order of magnitude different. This is because, under our constitutional scheme,
    the Legislature is empowered to issue subpoenas in order to conduct the investigations
    that are necessary to perform its crucial functions of enacting legislation and overseeing
    the operations of government, not to further its own private interests. See 
    Watkins, 354 U.S. at 187
    , 200. In this regard, the Supreme Court has long held that Congress must be
    deemed to “possess[] every other power essential to preserve the departments and
    institutions of the general government from impairment or destruction, whether
    threatened by force or by corruption.” Burroughs v. United States, 
    290 U.S. 534
    , 545
    (1934).
    Thus, Article I to the House of Representatives assigns the “sole Power of
    Impeachment”, U.S. Const. art. I, § 2, cl. 5, and it also vests Congress as a whole with
    “[a]ll legislative Powers,” U.S. Const. art. I, § 1. Moreover, it grants to Congress the
    “power of inquiry[,]” 
    McGrain, 273 U.S. at 174
    , which the House and the Senate may
    delegate to their respective committees and subcommittees, and this power is an
    “integral part” of the legislative and impeachment authority. 
    Eastland, 421 U.S. at 505
    ;
    see also Nixon v. Adm’r of Gen. Servs., 
    433 U.S. 425
    , 499 (1977). Additionally, the
    Supreme Court has recognized that “where the legislative body does not itself possess
    the requisite information—which not infrequently is true—recourse must be had to
    others who do possess it.” 
    McGrain, 273 U.S. at 175
    . It specifically observed that
    “[e]xperience has taught that mere requests for such information often are unavailing,
    and also that information which is volunteered is not always accurate or complete; so
    71
    some means of compulsion are essential to obtain what is needed.” 
    Eastland, 421 U.S. at 504
    –05.
    The law also plainly establishes that one of these means of compulsion—known
    as “the subpoena power”—“may be exercised by a committee acting . . . on behalf of
    one of the Houses.” 
    Id. at 505.
    20 And with respect to the duty that a recipient of such a
    subpoena has to perform as Congress has demanded, the Supreme Court has specifically
    noted that “[a] subpoena has never been treated as an invitation to a game of hare and
    hounds, in which the witness must testify only if cornered at the end of the chase.”
    
    Bryan, 339 U.S. at 331
    . “If that were the case, then, indeed, the great power of
    testimonial compulsion, so necessary to the effective functioning of courts and
    legislatures, would be a nullity.” 
    Id. (emphasis added).
    For present purposes, all this means is that, when a committee of Congress seeks
    testimony and records by issuing a valid subpoena in the context of a duly authorized
    investigation, it has the Constitution’s blessing, and ultimately, it is acting not in its
    own interest, but for the benefit of the People of the United States. If there is fraud or
    abuse or waste or corruption in the federal government, it is the constitutional duty of
    Congress to find the facts and, as necessary, take corrective action. Conducting
    investigations is the means that Congress uses to carry out that constitutional
    20
    Thus, the “particularized” injury requirement, 
    Lujan, 504 U.S. at 560
    , is satisfied. Pursuant to the
    House of Representative’s authority to “determine the Rules of its Proceedings,” U.S. Const. art. I, § 5,
    cl. 2, the House has empowered the Judiciary Committee to “conduct at any time such investigations
    and studies as it considers necessary or appropriate in the exercise of its responsibilities,” House Rule
    XI.1(b)(1). Moreover, the Judiciary Committee has been authorized “to require, by subpoena or
    otherwise, the attendance and testimony of such witnesses and the production of such books, records,
    correspondence, memoranda, papers, and documents as it considers necessary.” House Rule
    XI.2(m)(1)(B). The Judiciary Committee alleges that the McGahn subpoena was issued pursuant to this
    authority. (See Compl. ¶¶ 71–72.) Therefore, his defiance of the Committee’s subpoena, “affect[s] the
    plaintiff in a personal and individual way.” 
    Lujan, 504 U.S. at 560
    n.1. It is the House of
    Representative’s particular constitutional rights, privileges, and duties that are being denied.
    72
    obligation. Thus, blatant defiance of Congress’ centuries-old power to compel the
    performance of witnesses is not an abstract injury, nor is it a mere banal insult to our
    democracy. It is an affront to the mechanism for curbing abuses of power that the
    Framers carefully crafted for our protection, and, thereby, recalcitrant witnesses
    actually undermine the broader interests of the People of the United States. Thus,
    DOJ’s hand-waving over the Judiciary Committee’s purported failure to establish a
    “cognizable” injury for standing purposes (Def.’s Mot. at 36–40) masks the substantial
    harm that results from an Executive branch official’s defiance of a congressional
    subpoena. But it is hard to imagine a more significant wound than such alleged
    interference with Congress’ ability to detect and deter abuses of power within the
    Executive branch for the protection of the People of the United States.
    Here, the Judiciary Committee has filed a complaint that alleges that the
    Committee was dutifully attempting to fulfill its constitutional duties when it issued a
    subpoena to former White House Counsel Donald F. McGahn II. (See, e.g., Compl.
    ¶ 1.) According to the Committee, it opened an investigation into potential misconduct
    by President Trump and his associates on March 4, 2019 (see 
    id. ¶ 57),
    and its
    investigation allegedly took on a new dimension after Special Counsel Robert Mueller
    issued his report. 21 The Judiciary Committee further alleges that it has not been able to
    21
    According to the Committee, the Mueller Report found that “‘[t]he Russian government interfered in
    the 2016 presidential election in sweeping and systematic fashion’” (Compl. ¶ 1 (quoting Mueller
    Report Vol. 1 at 1)); that this interference was “intended to benefit the Trump Presidential campaign”
    (id. ¶ 26 (citing Mueller Report Vol. 1 at 1)); and that President Trump “repeatedly attempted to shut
    down the investigation into Russia’s interference in America’s 2016 election and to conceal his own
    involvement and potential misconduct from the public” (id. ¶ 32). The truth or falsity of the Mueller
    Report’s findings and conclusions is immaterial to the present legal action, and neither party suggests
    otherwise. (See Pl.’s Stmt. of Facts at 3 n.1 (“In paragraphs 6-68, the Judiciary Committee does not
    recount information included in the Report to establish the truth of the matters asserted. Rather, the
    Committee relays what the Special Counsel has told Congress and the American people in order to
    explain the basis for the Committee’s investigation.”); see also Def.’s Resp. to Pl.’s Stmt. of Facts,
    73
    complete its mission of getting to the bottom of the facts and circumstances that are
    chronicled in the Mueller Report, partly because McGahn “is the most important fact
    witness in the [Committee’s] consideration of whether to recommend articles of
    impeachment and its related investigation of misconduct by the President, including
    acts of obstruction of justice described in the Special Counsel’s Report” (id. ¶ 97), and
    McGahn has refused to appear before the Committee to provide his testimony, at
    President Trump’s direction (see 
    id. ¶¶ 1,
    7.) Consequently, the Committee requests
    that this Court “declare that McGahn’s refusal to appear before the Committee in
    response to the subpoena issued to him” is unlawful, and that it “issue an injunction
    requiring McGahn to appear forthwith before the Committee[.]” (Compl. at 53.)
    With respect to its evaluation of the sufficiency of the Judiciary Committee’s
    injury allegations, this Court must accept these statements of fact as true. See 
    Lujan, 504 U.S. at 561
    (explaining that, at the pleading stage, allegations regarding standing
    are treated in the same manner as all other factual allegations and must be accepted as
    true). Furthermore, although a heightened evidentiary standard applies to standing
    arguments made in the context of cross-motions of summary judgment, see id.; see also
    Food & Water Watch, Inc. v. Vilsack, 
    808 F.3d 905
    , 912–13 (D.C. Cir. 2015), the
    Judiciary Committee has submitted affidavits and exhibits to substantiate their
    allegations that McGahn has impeded their investigation (see Berke Decl; Tatelman
    Decl.), and DOJ does not appear to contest that the Muller Report did, in fact, contain
    the findings that the Judiciary Committee alleges, or that the Committee has, in fact,
    ECF No. 32-2, ¶¶ 6–68 (maintaining that the Mueller Report itself provides the “complete and accurate
    statement of its contents” and that the Judiciary Committee’s recitation of its contents “is not a material
    fact under Fed. R. Civ. P. 56(c)”).
    74
    undertaken an investigation to evaluate the Report’s claims (see Def.’s Resp. to Pl.’s
    Stmt. of Facts, ¶¶ 6–68, 75–76).
    Moreover, for the purpose of determining whether the Judiciary Committee has
    alleged a sufficient injury-in-fact to generate a concrete interest in the outcome of this
    litigation, it is irrelevant that the Committee already has access to many, if not all, of
    McGahn’s sworn statements on this issue (McGahn’s interviews are referenced
    repeatedly in the text of the Mueller Report (see Compl. ¶¶ 34–51)), nor does it matter
    that the Committee might be able to find out what it seeks to get from McGahn in some
    other fashion (see, e.g., Def.’s Mot. at 79–80). This is because, as a committee of
    Congress, the Judiciary Committee has the “broad power” under Article I of the
    Constitution to conduct its investigations however it sees fit, so long as it does not
    impinge upon the constitutional rights of those it undertakes to question. 
    Watkins, 354 U.S. at 198
    –99. And, here, the Committee avers that, among other things, it wants
    McGahn to appear in person to testify about the events in question so that the
    Committee can evaluate his credibility. (See Pl.’s Mem. at 27 (asserting that
    “McGahn’s testimony is particularly important because, even as President Trump has
    directed McGahn to defy the Committee’s subpoena, the President has waged an
    extensive campaign to discredit the Special Counsel’s investigation, impugn McGahn’s
    credibility, and deny McGahn’s account of the facts” (citation omitted); see also 
    id. 27– 28;
    Pl.’s Reply at 60; Hr’g Tr. at 10:21–11:17.) What matters from the standpoint of
    evaluating the Committee’s Article III standing is that the Judiciary Committee has
    alleged an actual and concrete injury to its right to compel information (like any other
    similarly situated subpoena-issuing plaintiff), that is traceable to McGahn’s defiance at
    75
    the Executive branch’s behest, and that this alleged violation of its interests is fully
    redressable by an order of this Court that requires McGahn to appear and testify.
    Of course, to describe the grave injury that defiance of congressional subpoena
    inflicts on a committee of Congress (and, by extension, on the People of the United
    States) is to demonstrate why DOJ’s reliance on the Raines case is misplaced. (See
    Def.’s Mot. at 36–40.) In Raines, six members of Congress who had voted against the
    Line Item Veto Act filed suit seeking a declaratory judgment that the Act, which was
    enacted and signed into law, was unconstitutional. 
    Raines, 521 U.S. at 814
    –17. The
    plaintiffs claimed that they had been injured by the possible future “dilution of
    institutional legislative power[,]” 
    id. at 826,
    which is a completely different type of
    injury than the harm to established constitutional investigatory rights at issue here.
    Moreover, the members of Congress in Raines invoked a generalized injury; in fact,
    they specifically declared that their injury was the “loss of a political power” that
    affected the entire institution of Congress “not the loss of any private right.” 
    Id. at 821.
    And rather than pointing to a concrete harm that resulted from enactment of the
    legislation, the plaintiffs claimed that the Line Item Veto Act had injured them by
    “alter[ing] the legal and practical effect of [their] votes.” 
    Id. at 836
    (quotation marks
    and citation omitted). The Supreme Court’s conclusion that there was no standing to
    sue under those circumstances is, thus, entirely inapposite to the claims that the
    Judiciary Committee brings today. See also 
    Mnuchin, 379 F. Supp. 3d at 17
    –18 (noting
    that “informational injuries to Congress arise ‘primarily in subpoena enforcement
    cases,’ which hold that the legislature ‘has standing to assert its investigatory power.’”
    76
    (quoting U.S. House of Representatives v. U.S. Dep’t of Commerce, 
    11 F. Supp. 2d 76
    (D.D.C. 1998)). 22
    2.      The Constitution Itself Provides A Cause Of Action For A
    Thwarted House Committee To Proceed In Federal Court
    The next purported barrier to the Judiciary Committee’s ability to enforce its
    subpoenas by filing a legal action in federal court is DOJ’s suggestion that the Judiciary
    Committee lacks a cause of action to do so. It is clear that all litigants who bring their
    claims to federal court for review must have a right to be there. In this regard, DOJ
    asserts that, unlike the Federal Rules of Civil Procedure that expressly authorize a
    person with a pending case to initiate a separate action in the district where compliance
    with a subpoena is required, see Fed. R. Civ. P. 45(g), there is no such provision with
    respect to the enforcement of legislative subpoenas. (Def.’s Mot. at 43.)
    This argument is unavailing because, as Judge Bates recognized in Miers, Article
    I of the Constitution is all the cause that a committee of Congress needs to seek a
    judicial declaration from the court regarding the validity and enforceability of a
    subpoena that it has allegedly issued in furtherance of its constitutional power of
    inquiry. Miers, 
    558 F. Supp. 2d
    at 94; see also Holder, 
    979 F. Supp. 2d
    at 22. This is
    because the Supreme Court has long recognized that the Legislative branch is not only
    22
    DOJ’s appeal to Walker v. Cheney is also unavailing. In Walker, the Comptroller General requested
    certain information from the Vice President on behalf of four 
    Senators. 230 F. Supp. 2d at 57
    –58. The
    Comptroller General sought to obtain withheld documents in order to “aid Congress in considering
    proposed legislation.” 
    Id. at 66–67.
    But, the district court held, the alleged injury to the House’s
    “general interests in legislating and oversight” was “too vague and amorphous to confer standing.”
    That was because Congress itself had “undertaken no effort to obtain the documents at issue, . . . no
    committee had requested the documents, and no congressional subpoena ha[d] been issued.” 
    Id. at 67–
    68. In addition, “the Comptroller General here has not been expressly authorized by Congress to
    represent its interests in this lawsuit.” 
    Id. Hence, “an
    injury with respect to any congressional right to
    information remain[ed] wholly conjectural or hypothetical.” 
    Id. (internal citations
    and quotations
    omitted).
    77
    vested with the broad power to conduct investigations under Article I of the
    Constitution, but it also has “an implied right to compel compliance with that
    investigative power.” Miers, 
    558 F. Supp. 2d
    at 90. Consistent with this Court’s
    observations about the legal significance of subpoena power more generally 
    (see supra
    Part III.C), Miers explains that “[t]he exercise of Congress’s investigative ‘power,’
    which the Executive concedes that Congress has, creates rights,” Miers, 
    558 F. Supp. 2d
    at 91, and that “by utilizing its power to issue subpoenas and proceed with an
    investigation via compulsory process, Congress creates a legal right to the responsive
    information that those subpoenas will yield[,]” 
    id. Importantly, the
    Supreme Court’s analysis of the Legislature’s Article I
    investigative power confirms that a committee of Congress’s right to enforce its
    subpoenas is intrinsic to its constitutional authority to conduct investigations in the first
    place. In McGrain v. Daugherty, 
    273 U.S. 135
    (1927), the Supreme Court stated
    unequivocally that “the power of inquiry—with process to enforce it—is an essential
    and appropriate auxiliary to the legislative function.” 
    McGrain, 273 U.S. at 174
    . Thus,
    it is the precedent of this district, as established in both Miers and in Committee on
    Oversight & Government Reform v. Holder, 
    979 F. Supp. 2d 1
    (D.D.C. 2013), that the
    powers provided to Congress in Article I of the Constitution necessarily include the
    “right to further an investigation by issuing subpoenas and enforcing them in court[.]”
    Holder, 
    979 F. Supp. 2d
    at 22.
    Past precedents also dispose of DOJ’s contention that just because Article I does
    not expressly mention the right of a committee of Congress to enforce its subpoena
    power in court means that the courts are now implying that the Constitution contains
    78
    such right in a manner that contravenes what the Supreme Court has said about implied
    causes of action. The Constitution also does not explicitly convey to Congress the
    specific right to conduct investigations (i.e., what the Supreme Court calls “the power
    of inquiry”), and yet, the Supreme Court found that such power is intrinsic to the
    “legislative Power” that Article I expressly conveys to Congress. Anderson v. Dunn, 
    19 U.S. 204
    , 230 (1821). So it is here. As explained in Anderson v. Dunn, “[t]here is not
    in the whole of [the Constitution], a grant of powers which does not draw after it others,
    not expressed, but vital to their exercise[.]” 
    id. at 225–26.
    And in light of McGrain’s
    conclusion (repeated here for emphasis) that “the power of inquiry—with process to
    enforce it—is an essential and appropriate auxiliary to the legislative function[,]”
    
    McGrain, 273 U.S. at 174
    , DOJ cannot seriously maintain that the power to enforce
    legislative subpoenas is not among these intrinsic rights. It also cannot be seriously
    debated that “‘the judiciary is clearly discernible as the primary means through which
    constitutional rights may be enforced’” Miers, 
    558 F. Supp. 2d
    at 88 (alternations
    omitted) (quoting Davis v. Passman, 
    442 U.S. 228
    , 242 (1979)); see also Bolling v.
    Sharpe, 
    347 U.S. 497
    (1954) (finding that the district court had erred in dismissing a
    suit seeking equitable relief brought directly under the Fifth Amendment, based on
    alleged race discrimination in school admissions); Jacobs v. United States, 
    290 U.S. 13
    ,
    15 (1933) (permitting a plaintiff to bring suit directly under the Fifth Amendment based
    on allegations that the United States had taken his property for public use without just
    compensation). Thus, DOJ’s strident contention that “the [Judiciary] Committee must
    also show that Congress has authorized a cause of action to litigate the Committee’s
    79
    claimed right to compel Mr. McGahn’s testimony” (Def.’s Mot. at 52) is plainly
    meritless. 23
    If Congress does somehow need a statute to authorize it to file a lawsuit to
    enforce its subpoenas in vindication of its thwarted constitutional rights (for the reasons
    explained above, it does not), then the Declaratory Judgment Act plainly serves that
    purpose, as both Judge Bates and Judge Amy Berman Jackson have previously found, in
    parallel contexts. See Miers, 
    558 F. Supp. 2d
    at 78–88; Holder, 
    979 F. Supp. 2d
    at 22.
    This Court, too, concludes that the Judiciary Committee has satisfied the three
    established elements for seeking a declaration of rights under this statute: (1) it has
    established “a case of actual controversy”; (2) it has invoked an “independent basis for
    federal jurisdiction”; and (3) it has filed an “appropriate pleading.” Miers, 
    558 F. Supp. 2d
    at 79 (internal quotation marks and citation omitted); see also 
    id. at 81–82
    (holding
    that where the Constitution creates a right, a plaintiff can use the Declaratory Judgment
    Act to vindicate that right); Holder, 
    979 F. Supp. 2d
    at 22 (finding that the House
    23
    Reed v. County Commissioners of Delaware County, Pa., 
    277 U.S. 376
    (1928), which DOJ cites
    here, is not to the contrary. DOJ characterizes that opinion as holding “that a committee’s power to
    issue subpoenas does not itself include the power to bring suit to enforce a subpoena in federal court”
    (see Def.’s Mot. at 52), but coming just months after the Court had held in McGrain that legislative
    subpoenas are an enforceable right of Congress, and given that Reed involved individual Senators who
    had filed suit to compel compliance with a Senate subpoena under circumstances in which those
    individual plaintiffs had not been authorized to sue on behalf of Congress, it is stretch to interpret the
    Supreme Court’s statement that the suit was not “authorized by law” to stand for the proposition that, if
    Congress authorizes a committee to file a subpoena-enforcement lawsuit, that committee still has no
    cause of action to sue. Similarly unavailing is DOJ’s reliance on Jesner v. Arab Bank, PLC, 
    138 S. Ct. 1386
    (2018) and Ziglar v. Abbassi, 
    137 S. Ct. 1843
    (2017). (See Def.’s Mot. at 53.) Both of those
    cases involved inferring private rights of actions for damages for violations of constitutional rights
    under Bivens v. Six Unkown Fed. Narcotics Agents, 
    403 U.S. 388
    (1971), an area in which the Supreme
    Court has traditionally urged particular caution and deference to Congress, based on separation of
    powers concerns. See 
    Jesner, 138 S. Ct. at 1402
    (finding that courts must defer to Congress regarding
    the creation of a damages remedy “if there are sound reasons to think Congress might doubt the
    efficacy or necessity” of such a remedy). No such concerns are present here—indeed far from it—
    because the Constitution conveys (and thus necessarily endorses) the power of inquiry, and Judiciary
    Committee seeks only declaration and an injunction to vindicate its constitutional rights. See Miers,
    
    558 F. Supp. 2d
    at 89 (“This is not a damages action. Thus, Bivens and its progeny are not strictly on
    point.”).
    80
    Committee “is not looking to the Declaratory Judgment Act as the source of the right it
    is seeking to vindicate in this Court, but rather as the source of the mechanism to
    achieve the vindication of a right derived elsewhere”). That is all the law requires.
    3.     There Is No Separation-Of-Powers Impediment To The Judiciary
    Committee’s Seeking To Vindicate Its Rights In Federal Court
    DOJ’s final argument as to why a duly authorized committee of the House of
    Representatives cannot be permitted to file a subpoena-enforcement lawsuit in federal
    court, even though ordinary civil litigants generally have unfettered access to the
    federal courts for this purpose, relies on a reassertion of constitutional separation-of-
    powers principles. (See Def.’s Mot. at 40–43.) Judge Bates soundly rejected DOJ’s
    separation-of-powers-based lack of standing arguments in Miers. See Miers, 558 F.
    Supp. 3d at 95–99. This Court further addresses most of the conceptual problems with
    DOJ’s arguments restricting the power of the courts to review a claim brought by a
    House committee against the Executive branch elsewhere in this Memorandum Opinion.
    
    (See supra
    Part IV.A.2.) In this section, the Court homes in on the obvious red flag that
    immediately appears with respect to even the most cursory review of DOJ’s arguments
    regarding the constitutional limits of a House committee’s subpoena-enforcement
    authority: the lack of any reason why the Constitution should be construed to
    command, or even countenance, this result, especially when other subpoena issuers
    routinely enlist the aid of the federal courts with respect to enforcing their mandates.
    (See Hr’g Tr. at 57:14–59:12.)
    Apparently undisturbed by the manifest inequity of treating a committee of
    Congress less favorably than a litigating private citizen when it comes to identifying the
    appropriate mechanisms for the vindication of established legal rights, DOJ’s brief
    81
    ignores this problem entirely. And when asked about it during the motions hearing (see
    Hr’g Tr. at 57:20–25 (Court noting that “people can issue subpoenas and they can also
    come to court if the person who receives the subpoena doesn’t provide the information
    that they say they are seeking to compel,” and then asking, “why is the House worse
    off?”)), DOJ’s counsel responded, first, that “the House has never bothered to pass a
    statute giving it the authority to do any of this” (id. at 58:10–11), and, second, that “the
    House doesn’t execute the laws” (id. at 59:1). The first response is of no moment, since
    the power to investigate and to issue subpoenas is vested in the House of
    Representatives by the Constitution itself 
    (see supra
    Part IV.B.2), and thus the
    Judiciary Committee does not need a statute to have the authority to act in vindication
    of its constitutional interests. The second point is likewise unavailing, because no one
    reasonably claims that a private individual who is seeking to have its subpoenas
    enforced in court is executing laws. See Clinton v. Jones, 
    520 U.S. 681
    , 701 (1997)
    (finding that “there is no suggestion that the Federal Judiciary is being asked to perform
    any function that might in some way be described as ‘executive.’ Respondent is merely
    asking the courts to exercise their core Article III jurisdiction to decide cases and
    controversies”).
    DOJ does little else to address this Court’s concerns about the implications of its
    argument that the Constitution requires the Judiciary Committee to go it alone with
    respect to seeking to have its subpoenas enforced, and thus, unlike other civil litigants,
    it cannot seek a court enforcement order. Nevertheless, DOJ is undaunted, and it seems
    to float three arguments concerning this issue. DOJ says (1) that the Judiciary
    Committee is not disadvantaged because it has other non-court options for enforcing its
    82
    subpoenas (see Def.’s Mem. at 41–42); (2) that, regardless, history establishes that the
    Committee does not have the right to sue in court (see 
    id. at 32–36);
    and (3) that there
    is persuasive and precedential case law in this district that holds that a House
    committee has no standing to sue the Executive branch (see 
    id. at 39.)
    For the
    following reasons, none of these arguments persuades this Court to conclude that the
    Judiciary Committee cannot proceed to press the legal claims it has brought in this
    lawsuit.
    First of all, the fact that the Judiciary Committee has “several political arrows in
    its quiver to counter perceived threats to its sphere of power[,]” Mnuchin, 
    379 F. Supp. 3d
    at 22—including, apparently, the manipulation of its appropriations power to starve
    the Executive branch of resources as a sanction for contempt (see Def. Mem. at 42; see
    also Hr’g Tr. at 65:17–20)—and, therefore, “this lawsuit is not a last resort for the
    House[,]” Mnuchin, 
    379 F. Supp. 3d
    at 22, is irrelevant. The elements that courts must
    consider to determine whether a plaintiff has Article III standing are well established
    
    (see supra
    n.19), and they do not include a “last resort” requirement. To the extent that
    federal courts have exercised their equitable powers to stay their own consideration of
    matters that are otherwise ripe for judicial review, it appears that they have done so in
    the relatively unusual circumstance in which the parties are on the brink of reaching a
    negotiated resolution of the conflict, see, e.g., AT & T 
    I, 551 F.2d at 394
    , or in the
    context of evaluating the justiciability of the plaintiff’s claim under the political
    question doctrine; the latter ordinarily involves assessing the series of factors that the
    Supreme Court prescribed in Baker v. Carr¸ 
    369 U.S. 186
    , 217 (1962), see also
    
    Zivotofsky, 132 S. Ct. at 1432
    (Sotomayor, J., concurring) (explaining that “the final
    83
    three Baker factors address circumstances in which prudence may counsel against a
    court’s resolution of an issue presented”). DOJ has disavowed the possibility that the
    parties here will settle (see Def.’s Accommodation Resp. at 2), and a quick review of its
    briefs indicates that it has not engaged with the Baker factors at all.
    What is more, DOJ’s suggestion that a thwarted House committee must eschew
    the courts and, instead, must rely on its “power to withhold appropriations” in order “to
    get the information that it needs” (Hr’g Tr. at 65:18–20) is nearly a practical nullity,
    because an appropriations sanction for non-compliance with a legislative subpoena
    cannot be implemented swiftly enough to preserve the utility of a defiant witness’s
    testimony, and it also cannot be achieved without the cooperation of the entire Congress
    as well as the President whom the Judiciary Committee is investigating and whose
    allegedly unlawful directive to his senior-level aides is the impetus for the Committee’s
    legal claims. It is also quite clear that if the House attempts an appropriations penalty,
    or if it utilizes its sometimes-mentioned inherent power to send the Sergeant at Arms to
    arrest the contemptuous official, those “political arrows” are far more likely to raise
    legitimate separation-of-powers concerns than allowing the Judiciary Committee to file
    a civil action in federal court.
    DOJ’s second contention fares no better. As the Court explained above, the fact
    that there are few recorded instances in the history of our Nation in which Congress has
    filed a legal claim against the Executive branch in court to enforce its subpoena rights
    (see Def.’s Mot. at 34–35), goes to show, at most, that the Legislature has rarely needed
    such assistance 
    (see supra
    Part IV. A.2.b). It says nothing about whether the Judiciary
    Committee can avail itself of the opportunity to file a legal action against the Executive
    84
    branch to protect against alleged transgressions of its Article I power of inquiry,
    consistent with well-established constitutional principles. And, again, DOJ has not
    offered a single case in which a binding authority has embraced the proposition that,
    under the Constitution, the House has no standing to proceed again the Executive
    branch in federal court despite its satisfaction of the well-worn requirements of a
    cognizable injury-in-fact that is redressable in the court. 
    (See supra
    n.19.)
    The only case that DOJ has offered that appears to provide direct support of this
    dubious legal proposition is a recent case from this district in which the court concluded
    that the House lacked standing to proceed in court with respect to its claim that the
    President’s declaration of a national emergency to procure funding for the border wall
    violated the Appropriations Clause of the Constitution and the Administrative
    Procedures Act. See Mnuchin, 
    379 F. Supp. 3d
    at 12; see also 
    id. at 10
    (“This is a case
    about whether one chamber of Congress has the ‘constitutional means’ to conscript the
    Judiciary in a political turf war with the President over the implementation of
    legislation.”). Notably, the Mnuchin case can be, and most likely should be, read to
    stand for the much more modest contention that the House had failed to satisfy the well-
    established injury-in-fact standing requirement, because the harm that it alleged was not
    a cognizable injury. See 
    id. at 13
    (“The Administration concedes, and the Court agrees,
    that only the first prong of the standing analysis—injury that is concrete and
    particularized—is at issue here. Applying the ‘especially rigorous’ analysis required,
    the Court finds that the House has failed to allege such an injury. So the Court must
    deny the House’s [preliminary injunction] motion.” (internal citation omitted)).
    Furthermore, in this regard, the Mnuchin case helpfully and specifically distinguished
    85
    “the supposed harm to Congress’ Appropriations power[,]” 
    id. at 16,
    from the harm to
    Congress’ well founded investigatory interests, 
    id. at 17
    , which is what the Judiciary
    Committee alleges in the instant case (see Pl’s Mem. at 34–35). But if the essential
    holding of Mnuchin is that “[t]he Committee lacks standing foremost because centuries
    of historical practice show that the injury the Committee claims is not one traditionally
    deemed capable of redress through judicial process[,]” as DOJ suggests (Def.’s Mem. at
    32 (citation omitted)), then this Court believes its holding is erroneous.
    Here is why. The assertion that historical practice alone compels the conclusion
    that a dispute between the Executive branch and the Legislature is non-justiciable
    appears to rest on the Supreme Court’s redressability reminder in Raines that a legally
    cognizable injury for standing purposes is an injury that has been “traditionally thought
    to be capable of resolution through the judicial process.” (See Def.’s Mem. at 33
    (quoting 
    Raines, 521 U.S. at 826
    ).) DOJ argues (and Mnuchin appears to accept) that
    Raines “teaches that in evaluating whether a suit between the political Branches is
    justiciable, a federal court must evaluate whether such a suit is consistent with
    historical practice.” (Def.’s Mem. at 32.) A review of Supreme Court case law in the
    more than two decades since Raines was decided casts doubt on DOJ’s conclusion that
    Raines’s historical overview was the primary determinant of the Supreme Court’s
    holding there that the patently amorphous harm that the plaintiffs had alleged was not a
    cognizable injury. But even if Raines implicitly amended the Supreme Court’s
    traditional Article III standing criteria to include an historical-practice element when a
    plaintiff’s injury is assessed for the purpose of determining standing, in this Court’s
    view, that element cannot be satisfied based solely on the fact that there are few
    86
    recorded cases in which that particular injury was previously claimed. As demonstrated
    above, a dearth of similar case law could just as easily be interpreted to mean that the
    political branches have typically been able to find other acceptable ways to resolve their
    disputes, and thus have avoided litigation. (See Part IV.A.2.b.) In other words, where
    the historical record shows that disputes between the Executive branch and the
    Legislature concerning the claimed injury are typically resolved through negotiation,
    the lack of prior cases says nothing about the capability of resolving those kinds of
    legal issues in the courts.
    This Court also notes, as a general matter, that the utility of history depends on
    an assumption that the terms and conditions of the “battle” between the political
    branches now are the same as those that gave rise to similar disputes in the past.
    However, we are at a point in history in which the Executive branch appears to be
    categorically rejecting once-accepted and standard applications of Legislative and
    Judicial branch authority; therefore, federal courts are being called upon to evaluate
    novel exercises of Executive power that allegedly threaten the prerogatives of the other
    branches of government in unique ways. See, e.g., Def.’s Mem. in Opp’n to the Mot.
    for Prelim. Inj., Make the Road N.Y. v. McAleenan, No. 19-cv-2369 (D.D.C.), at 75
    (characterizing the statutorily required remedy for a procedural violation of the
    Administrative Procedure Act as a “nationwide injunction” and, having done so,
    arguing that that courts cannot invalidate unlawful agency rules in their entirety); El
    Paso Cty. v. Trump, No. 19-cv-66, 
    2019 WL 5092396
    (W.D. Tex. Oct. 11, 2019)
    (rejecting the Executive branch argument that transferring funds for border wall
    construction from congressional appropriations made for other purposes is lawful); City
    87
    of Philadelphia v. Attorney Gen. of United States, 
    916 F.3d 276
    (3d Cir. 2019), reh’g
    denied (June 24, 2019) (holding that Executive branch withholding of a congressional
    law enforcement grant because the City failed to comply with certain conditions that
    required greater coordination with federal officials on matters of immigration
    enforcement exceeded the authority granted to the Attorney General by Congress). This
    reality plainly limits the lessons that can properly be drawn from history. It also
    renders unpersuasive DOJ’s assertion that, based on the branches’ lengthy track record
    of negotiated resolutions, today’s Judiciary Committee should be deemed to lack
    standing to protect its vital interests in the courts. In this Court’s view, the fact that
    federal courts throughout history have not had occasion to address the kinds of
    perceived threats to constitutional and procedural norms that are being brought to
    federal courts’ attention regularly in the present day actually says more about the
    unprecedented nature of the challenged actions and legal positions of the Executive
    branch than it does about the nature of the Judiciary Committee’s claim or harm.
    In any event, the federal courts have their own recorded history, and it consists
    of the precedential rulings that prior courts have rendered with respect to similar legal
    issues. 
    (See supra
    Part III.B.) In this regard, the Miers case persuasively determined
    that the Judiciary Committee had Article III standing to file a subpoena-enforcement
    lawsuit seeking to vindicate its investigatory interests when a former White House
    Counsel refused to appear for testimony as directed. See Miers, 
    558 F. Supp. 2d
    at 68–
    78. And that case further noted that “the [Supreme] Court has never held that an
    institution, such as the House of Representatives, cannot file a suit to address an
    institutional harm.” 
    Id. at 70.
    No interim developments have changed the status of the
    88
    law. Additionally, upon review of the Supreme Court’s past jurisprudence on the
    matter, this Court found the following quote that renders dubious the standing and
    cause-of-action arguments that DOJ presses now: “Without the power to investigate—
    including of course the authority to compel testimony, either through its own processes
    or through judicial trial—Congress could be seriously handicapped in its efforts to
    exercise its constitutional function wisely and effectively.” Quinn v. United States, 
    349 U.S. 155
    (1955).
    C.     The President Does Not Have The Power To Prevent His Aides From
    Responding To Legislative Subpoenas On The Basis Of Absolute
    Testimonial Immunity
    The merits legal issues that the instant dispute between the House Judiciary
    Committee and the Executive branch raises are straightforward. The Committee claims
    that it has issued a lawful subpoena to former White House Counsel Donald F. McGahn
    II (see Compl. ¶ 107); that McGahn has refused to appear before the Committee to
    provide testimony as required (id. ¶ 109); and that “[t]here is no lawful basis for
    McGahn’s refusal to appear before the Judiciary Committee” (id. ¶ 110). For its part,
    DOJ asserts that, consistent with its understanding of the longstanding view of the
    Department’s Office of Legal Counsel, there is a lawful basis for McGahn’s defiance of
    the Committee’s valid subpoena: the President has ordered him not to. (See Def.’s
    Mot. at 27.) DOJ asserts that current and former senior-level presidential aides have
    “absolute testimonial immunity” from compelled congressional process, as a matter of
    law; therefore, if the President invokes “executive privilege” over a current or former
    aides’ testimony—as he has done with respect to McGahn—that aide need not accede to
    the lawful demands of Congress. (Id. at 27–28.) Thus, it is important to note at the
    outset, what is not at issue in the instant case. No one contests the lawfulness of the
    89
    Judiciary’s subpoena, and no one maintains that, if McGahn has the legal duty to testify
    before the Committee, that a senior-level aide in his position has no right to invoke
    executive privilege to withhold certain information in the course of his testimony, as
    appropriate. 24
    For the reasons that follow, this Court finds that the President does not have
    (and, thus, cannot lawfully assert) the power to prevent his current and former senior-
    level aides from responding to congressional subpoenas. As Judge Bates explained in
    Miers, as a matter of law, such aides do not have absolute testimonial immunity.
    Therefore, as it relates to them, a valid legislative subpoena issued by a duly authorized
    committee of Congress gives rise to a legally enforceable duty to perform. The
    President cannot override this duty, notwithstanding OLC’s ostensible recognition of
    such power. Accordingly, if a duly authorized committee of Congress issues a valid
    legislative subpoena to a current or former senior-level presidential aide, the law
    requires the aide to appear as directed, and assert executive privilege as appropriate.

    1.      Miers Squarely Rejects The Argument Senior-Level Presidential
    Aides Enjoy Absolute Testimonial Immunity
    Committee on Judiciary, U.S. House of Representatives v. Miers, 
    558 F. Supp. 2d 53
    (D.D.C. 2008), is the only recorded case in our Nation’s history that directly
    addresses the legal argument that a senior-level presidential aide is immune to a
    24
    The astute reader will note that the Judiciary Committee’s complaint does include an allegation that
    “[t]he President has waived executive privilege as to the subpoenaed testimony that relates to matters
    and information discussed in the Report.” (Compl. ¶ 112.) However, by consent of the parties and
    with respect to the Court’s consideration of the pending cross-motions for summary judgment, the
    question of whether and to what extent McGahn can actually invoke executive privilege during his
    testimony before the Committee in light of the President’s alleged waiver has been put on hold.

    legislative subpoena seeking testimony when the President directs him to ignore that
    congressional mandate. The dearth of cases involving compelled congressional process
    issued to Executive branch officials is likely attributable to the fact that subpoena-
    related conflicts between Congress and the Executive branch are usually negotiated,
    rather than litigated, as DOJ points out. (See Def.’s Mot. at 33–36.) In addition, while
    direct subpoena-related disputes between Congress and the Executive branch do exist, it
    appears that such conflicts have been relatively infrequent; the Court suspects that this
    is attributable to the fact that, as a general matter, Congress’s clear constitutional
    prerogative to compel information in furtherance of its legislative and oversight
    functions has been historically recognized and is typically widely respected. See
    Watkins, 
    354 U.S. 187
    –88. Regardless, Miers is precedential with respect to the merits
    of DOJ’s assertion that absolute testimonial immunity shields senior-level presidential
    aides, because Judge Bates squarely confronted the issue of whether the law permits the
    legal duty that arises when a senior-level presidential aide receives a legislative
    subpoena to be, in essence, canceled by the President.
    In Miers, Judge Bates begins by stating his conclusion that “the asserted absolute
    immunity claim here is entirely unsupported by existing case law.” Miers, 
    558 F. Supp. 2d
    at 99. The court explained that it had reached that conclusion primarily because
    “there is Supreme Court authority that is all but conclusive on this question and that
    powerfully suggests that such advisors do not enjoy absolute immunity.” 
    Id. Miers then
    turned to that case law, beginning with United States v. Bryan, 
    339 U.S. 323
    (1950), in which “[t]he Supreme Court has made it abundantly clear that compliance
    with a congressional subpoena is a legal requirement.” 
    Id. (citing Bryan,
    339 U.S. at
    91
    331). 25 The Miers court next explained how, in Harlow v. Fitzgerald, 
    457 U.S. 800
    (1982)—a case in which senior White House aides had been sued for civil damages—
    the Supreme Court had “virtually foreclosed” the argument that senior-level White
    House aides were entitled to absolute testimonial immunity. Miers, 
    558 F. Supp. 2d
    at
    100–01. This was because, according to Miers, Harlow had concluded that such aides
    were, at best, entitled to qualified immunity, notwithstanding the fact that “absolute
    immunity [for civil damages] extended to legislators, judges, prosecutors, and the
    President himself[.]” 
    Id. at 100;
    see also 
    id. (noting that
    , in Harlow, “the Supreme
    Court rejected the analogy to legislative aides that the Executive now invokes here”). 26
    Even with respect to the underlying contention that the President himself is
    entitled to absolute testimonial immunity, Miers found binding Supreme Court cases
    that compelled the opposite conclusion. For example, according to Judge Bates, United
    States v. 
    Nixon, 418 U.S. at 707
    –08, holds that the President “may only be entitled to a
    presumptive, rather than an absolute, privilege[,]” and it would be manifestly
    inconsistent with the Supreme Court’s holding in that regard to accord presidential
    aides a “superior card of immunity.” Miers, 
    558 F. Supp. 2d
    at 103. Judge Bates also
    noted that, in Clinton v. Jones, 
    520 U.S. 681
    (1997), “then-Chief Justice Rehnquist
    joined in the holding that even the demands of the President’s schedule could not
    25
    Miers noted, in particular, Bryan’s classic observation that “[a] subpoena has never been treated as
    an invitation to a game of hare and hounds, in which the witness must testify only if cornered at the end
    of the chase.” Miers, 
    558 F. Supp. 2d
    at 99 (quoting 
    Bryan, 339 U.S. at 33
    ) (internal quotation marks
    omitted).
    26
    Harlow addressed the applicability of the “alter ego” derivative immunity that the Supreme Court
    had determined applied to legislative aides in a case called Gravel v. United States, 
    408 U.S. 606
    (1972), to senior-level presidential aides who worked in the White 
    House. 457 U.S. at 809
    –11. Like
    DOJ in this case (and in Miers), the argument on the table was that senior-level presidential aides
    should be deemed to have the absolute immunity from civil damages that the law confers to their boss.
    
    Id. at 808.
    As Miers pointed out, the Harlow Court rejected that argument. 
    Id. at 813.
    92
    relieve him of the duty to give a civil deposition.” Miers, 
    558 F. Supp. 2d
    at 104
    (citing 
    Clinton, 520 U.S. at 706
    ). And based on this key holding, Judge Bates pointed
    out that “[i]f the President must find time to comply with compulsory process in a civil
    lawsuit, so too must his senior advisors for a congressional subpoena.” 
    Id. at 105.
    Miers also specifically rejected the asserted separation-of-powers basis for
    recognizing absolute testimonial immunity by relying on the D.C. Circuit’s language in
    Nixon v. Sirica, 
    487 F.2d 700
    (D.C. Cir. 1973). There, in the context of a case
    involving the enforcement of a grand jury subpoena duces tecum served on the
    President, the Circuit specifically asserted that, “[i]f the claim of absolute privilege was
    recognized, its mere invocation by the President or his surrogates could deny access to
    all documents in all the Executive departments to all citizens and their representatives,
    including Congress, the courts as well as grand juries, state governments, state officials
    and all state subdivisions.” 
    Sirica, 487 F.2d at 715
    ; see also 
    id. (noting that
    , if absolute
    immunity existed, “[t]he Freedom of Information Act could become nothing more than
    a legislative statement of unenforceable rights[,]” and cogently concluding that
    “[s]upport for this kind of mischief simply cannot be spun from incantation of the
    doctrine of separation of powers”). And Judge Bates ably reasoned that “[t]hat passage
    rather plainly contemplates that executive privilege is not absolute even when
    Congress—rather than a grand jury—is the party requesting the information.” Miers,
    
    558 F. Supp. 2d
    at 103.
    Finally, Miers further recognized that, “[t]ellingly, the only authority that the
    Executive can muster in support of its absolute immunity assertion are two OLC
    opinions authored by Attorney General Janet Reno and Principal Deputy Assistant
    93
    Attorney General Steven Bradbury, respectively.” 
    Id. at 104
    (citing Assertion of
    Executive Privilege With Respect to Clemency Decision, 
    23 Op. O.L.C. 1
    (1999);
    Immunity of the Former Counsel to the President From Compelled Congressional
    Testimony, 
    31 Op. O.L.C. 191
    (2007)). Miers explained that because “[t]hose opinions
    conclude that immediate advisors to the President are immune from compelled
    congressional testimony[,] [t]he question, then, is how much credence to give to those
    opinions.” 
    Id. Ultimately, Miers
    determined that the opinions were not persuasive,
    largely because “[n]either cites to a single judicial opinion recognizing the asserted
    absolute immunity.” 
    Id. Furthermore, “the
    three-page Bradbury OLC opinion was
    hastily issued on the same day that the President instructed Ms. Miers to invoke
    absolute immunity, and it relies almost exclusively upon the conclusory Reno OLC
    opinion and a statement from a memorandum written by then-Assistant Attorney
    General William Rehnquist in 1971.” 
    Id. In this
    Court’s view, Miers employs sound reasoning. And with respect to the
    merits analysis, this Court adopts its absolute testimonial immunity analysis in full. In
    particular, the Court, too, reads the cited cases to support the finding that DOJ’s
    absolute testimonial immunity argument is all but foreclosed by the binding case law
    the Miers cites, coupled with the logical flaws in DOJ’s legal analysis, which is laid out
    in the discussion below. In short, this Court finds that the Miers court rightly
    determined not only that the principle of absolute testimonial immunity for senior-level
    presidential aides has no foundation in law, but also that such a proposition conflicts
    with key tenets of our constitutional order. And, notably, no other court has considered
    94
    the absolute testimonial immunity question that Miers addressed since that case was
    decided. 27
    In the context of the instant case, DOJ responds by asserting that Miers was
    wrongly decided. (See Def.’s Mot. at 48.) Moreover, and in any event, DOJ has
    emphasized that Miers’s sphere of influence is exceedingly limited. (See Hr’g Tr. at
    118:13–118:14.) The thrust of the latter contention is that Miers is only one opinion—
    no binding authority followed—and, implicitly, the law is not established by the word
    of a single district court judge. See 
    id. On the
    other hand, says DOJ, scores of OLC
    attorneys have considered this issue over the past five decades, and in a series of
    opinions, OLC has carefully concluded that senior-level presidential aides do enjoy
    absolute testimonial immunity. (See Def.’s Mot. at 60.) And by minimizing Miers’s
    reach in this way, DOJ suggests that, in the absence of a groundswell of judges
    rejecting the concept, this Court should not readily find that the law is what Miers
    concluded.
    Setting aside the implications of DOJ’s argument for this district court’s
    consideration of these issues, its effort to undercut Miers’s holding is ineffectual,
    primarily because the argument inappropriately downplays both the importance of prior
    precedent in establishing the law as the next court understands it, and also the fact that
    DOJ itself controls whether more courts will have the opportunity to rule on the issue.
    To be sure, Miers is just one non-binding opinion. But, as noted, its analysis with
    27
    In Committee on Oversight & Government Reform v. Holder, District Judge Amy Berman Jackson
    evaluated whether, pursuant to a congressional subpoena, documents over which the Attorney General
    had asserted executive privilege must be turned over to the congressional committee. 
    979 F. Supp. 2d 1
    . Although the Holder opinion adopts Miers’s reasoning with respect to the threshold issues of
    jurisdiction, standing, and cause of action, see 
    id. at 10
    –12, 17–26, that court had no occasion to
    consider the merits of the absolute testimonial immunity claim that DOJ makes here.
    95
    respect to the absolute testimonial immunity issue is directly on point; therefore, it has
    considerable sway in terms of this Court’s conclusions. Moreover, and in any event,
    this Court cannot ignore it and still remain consistent with traditional juridical norms.
    Thus, DOJ’s best chance of persuading this Court to rule differently was to
    counter the various aspects of Miers’s holding directly; a skillful play-by-play of
    Miers’s alleged analytical flaws would have been most useful. Instead, in its briefing,
    DOJ has presented essentially the same threshold and merits arguments that Miers’s
    rejected, almost as if this was a matter of first impression, and thus, it has given the
    Court no reasonable basis to distinguish the circumstances of the instant case, nor any
    principled reason to interpret the law in a different fashion than Judge Bates did, as
    explained above. (See, e.g., Def.’s Mot. at 48–50 (asserting, over the span of two
    pages, that Miers was wrongly decided with respect to the threshold jurisdictional and
    standing issues, before proceeding to draw solely from OLC opinions to support the
    argument that senior-level presidential aides have absolute testimonial immunity).) The
    Court also observes that the lack of other cases on these issues is at least in part
    attributable to DOJ’s prior rational decisions to enter into negotiations over the scope of
    testimony and records when past Executive branch officials received a legislative
    subpoena, rather than proceed to court to litigate the purported scope of those officials’
    purported immunity. (Def.’s Mot. at 32–36.) DOJ further argues here that an
    Executive branch official’s alleged immunity to compelled congressional process is a
    non-justiciable issue. (Def.’s Mot. at 31–52.) Surely, DOJ cannot both act to keep the
    immunity issue away from the courts, and also be heard to suggest that the paucity of
    precedent is itself sufficient proof that the law must countenance the concept.
    96
    2.     OLC’s Long-Held View That Senior-Level Presidential Aides Have
    Absolute Testimonial Immunity Is Neither Precedential Nor
    Persuasive
    That all said, it is certainly true that OLC has long been of the view that senior-
    level presidential aides have absolute testimonial immunity; indeed, as Miers indicates,
    the first recorded statement of the agency that specifically commits this view to writing
    was authored in 1971. See Mem. from William H. Rehnquist, Assistant Attorney
    General, Office of Legal Counsel, to John D. Ehrlichman, Assistant to the President for
    Domestic Affairs, Power of Congressional Committee to Compel Appearance or
    Testimony of “White House Staff” (Feb. 5, 1971) (“1971 Memorandum”). In that year,
    then-Assistant Attorney General William Rehnquist produced a memorandum on the
    point that maintained (without direct citation) that “[t]he President and his immediate
    advisers—that is, those who customarily meet with the President on a regular or
    frequent basis—should be deemed absolutely immune from testimonial compulsion by a
    congressional committee.” 
    Id. at 7.
    This OLC memorandum further indicated that such
    persons “not only may not be examined with respect to their official duties, but they
    may not even be compelled to appear before a congressional committee.” 
    Id. But, of
    course, as definitive as this statement of law sounds, OLC serves as legal counsel to the
    Executive branch, and “the Executive cannot be the judge of its own privilege[.]”
    
    Miers, 558 F. Supp. 2d at 106
    . Consequently, its statement of the law is “entitled to
    only as much weight as the force of [its] reasoning will support.” 
    Id. at 104.
    In this Court’s view, the persuasiveness of OLC opinion that senior-level
    presidential aides enjoy immunity from compelled congressional process turns on two
    familiar factors: the authority that is provided in support of this proposition, and the
    reasons that are provided for why the author reached this conclusion. With respect to
    97
    the first consideration, it cannot be overstated that the 1971 Memorandum does not cite
    to a single case that stands for the asserted proposition, and the ten-plus subsequent
    statements by OLC that DOJ points to in support of this immunity simply reference
    back to the 1971 Memorandum without providing any court authority. It goes without
    saying that longevity alone does not transform an unsupported notion into law.
    As for the logic behind the view, the original memorandum appears to reason by
    by analogy. It begins by recognizing the breadth of Congress’ power of inquiry, which
    admittedly “carries with it the power to compel the testimony of a witness.” 1971 Mem.
    at 1. And then as if providing the solution to a problem that it had not yet identified,
    the memo states that “if White House staff personnel are to be exempt from appearing
    or testifying before a congressional committee, it is because they have some special
    immunity or privilege not accorded others.” 
    Id. at 1.
    The remainder of the 8-page
    document devotes itself to developing potential reasons for such a privilege. It
    suggests, for example, “a certain analogy to judicial proceedings[,]” in which a
    “distinction” is made “between a claim of absolute immunity from even being sworn in
    as a witness, and a right to claim privilege in answering certain questions in the course
    of one’s testimony as a witness.” 
    Id. at 4.
    Ultimately, the 1971 Memorandum pushes for the former, on the basis of a
    handful of historical examples in which former assistants to various Presidents blatantly
    refused to appear before Congress in response to a legislative subpoena. See 
    id. at 5–6.
    At least one of these folks was apparently polite enough to write a letter to the
    committee that “grounded his refusal on the confidential nature of his relationship with
    the President.” 
    Id. at 5.
    But others merely sent congressional subpoenas back with the
    98
    simple statement that “[i]n each instance that President directed me, in view of my
    duties as his Assistant, not to appear before your subcommittee.” 
    Id. at 5;
    see also 
    id. at 6.
    Tellingly, the 1971 Memorandum does not purport to suggest that the law
    already countenanced such behavior. Rather, the posture of the Memorandum appears
    to be a policy piece that provides its client with arguments for why it should be thus.
    Moreover, as Miers notes, Rehnquist admitted that “his conclusions [were] ‘tentative
    and sketchy,’” Miers, 
    558 F. Supp. 2d
    at 104 (quoting 1971 Mem.at 7), and in his later
    role as a Supreme Court Justice, he “apparently recanted those views[,]” 
    id. In one
    especially candid moment in the text of the Memorandum, Rehnquist admits that the
    historical precedents for refusing a congressional subpoena “are obviously quite
    inconclusive” but that “[i]n a strictly tactical sense, the Executive Branch has a
    headstart in any controversy with the Legislative Branch, since the Legislative Branch
    wants something the Executive Branch has, and therefore the initiative lies with the
    former.” 1971 Mem. at 7. He continued: “[a]ll the Executive has to do is maintain the
    status quo and he prevails.” 
    Id. It is
    not surprising that, per this initial internal effort
    to establish the ways in which certain White House staff could prevail in any conflict
    with Congress over their legally enforceable duty to appear for testimony when
    subpoenaed, OLC subsequently developed an entire series of statements, each of which
    references the 1971 Memorandum, but none of which specifically acknowledges that the
    initial basis for this conclusion was seemingly formed out of nothing. 28
    28
    The Executive appears to have adopted a practice of regularly securing a new OLC opinion on the
    existence of testimonial immunity whenever faced with a new Congressional subpoena. See, e.g.,
    Testimonial Immunity Before Congress of the Assistant to the President and Senior Counselor to the
    99
    This inauspicious start does not bode well for this Court’s determination of
    whether OLC’s persistent opinion that senior-level aides to the President are absolutely
    immune from having to respond to compelled congressional process should be credited.
    Additionally, subsequent developments in caselaw have cast doubt on the 1971
    Memorandum’s suggestion that the matter of the President’s own absolute immunity
    was settled because “[e]veryone associated with the Executive Branch from [the
    prosecution of Aaron Burr] until now, so far as I know, has taken the position that the
    President himself is absolutely immune from subpoena by anyone[.]” 1971 Mem. at 3;
    see also Clinton v. Jones, 
    520 U.S. 681
    (1997); United States v. Nixon, 
    418 U.S. 683
    (1974). 29 Moreover, in this first formal floating of the principle of absolute testimonial
    immunity for certain aides of the President, the author was also crystal clear that the
    “absolute immun[ity] from testimonial compulsion by a congressional committee” that
    he was proposing was primarily due to the fact that such “immediate advisors” are
    “presumptively available to the President 24 hours a day, and the necessity of either
    accommodating a congressional committee or persuading a court to arrange a more
    convenient time, could impair that availability.” 1971 Mem. at 7. Of course, that
    analysis does not support the extension of absolute immunity to former senior-level
    aides that DOJ has pressed in recent times.
    President, 43 Op. O.L.C. __, at *1; Immunity of Former Counsel to the President from Compelled
    Cong. Testimony, 
    31 Op. O.L.C. 191
    (2007).
    29
    Miers suggests that the contention that the President enjoys absolute immunity from compelled
    congressional process was dubious as a legal proposition long before the Nixon and Clinton cases. See
    Miers, 
    558 F. Supp. 2d
    at 70. In this regard, Judge Bates points to Chief Justice Marshall’s opinion in
    United States v. Burr, 
    25 F. Cas. 30
    (C.C.D. Va. 1807). In Burr, Chief Justice Marshall explained that
    “the obligation [to comply with a subpoena] . . . is general; and it would seem that no person could
    claim an exemption from [it].” 
    Id. at 34
    (emphasis added). Therefore, in Chief Justice Marshall’s
    view, “[t]he guard, furnished to [the President], to protect him from being harassed by vexatious and
    unnecessary subpoenas, is to be looked for in the conduct of a court after those subpoenas have issued;
    not in any circumstance which is to precede their being issued.” 
    Id. 100 In
    fairness, over time, the initial take on absolute testimonial evolved. It appears
    that OLC’s subsequent statements in support of this proposition were beefed up with
    various other reasons for why one could plausibly assert that certain aides of the
    President should be absolutely immune from having to testify before Congress, which
    reasons largely invoke constitutional separation of powers concerns, including potential
    harassment of the aides (and thus, the President), the risk of disclosure of information
    covered by executive privilege, and the appearance that the Executive branch is
    subordinate to the Legislature. See, e.g., Testimonial Immunity Before Congress of the
    Assistant to the President and Senior Counselor to the President, 43 Op. O.L.C. __, at
    *2 (“Absent immunity, congressional committees could wield their compulsory power
    to attempt to supervise the President’s actions, or to harass those advisers in an effort to
    influence their conduct, retaliate for actions the committee disliked, or embarrass and
    weaken the President for partisan gain.” (quotation marks and citation omitted));
    McGahn OLC Mem., 43 Op. O.L.C.__, at *5 (“The President is a separate branch of
    government. He may not compel congressmen to appear before him. As a matter of
    separation of powers, Congress may not compel him to appear before it.” (quotation
    marks and citation omitted)); Immunity of the Assistant to the President, 38 Op. OLC at
    *4 (“The pressure of compelled live testimony about White House activities in a public
    congressional hearing would . . . create an inherent and substantial risk of inadvertent
    or coerced disclosure of confidential information relating to presidential
    decisionmaking—thereby ultimately threatening the President’s ability to receive
    candid and carefully considered advice from his immediate advisers.”). Many of these
    reasons appear in the brief that DOJ has submitted to support absolute immunity in the
    101
    context of this case. But, unfortunately for DOJ, its mere recantation of these
    aspirational assertions does not make the proposition any more persuasive, and in fact,
    given the history of how OLC’s opinion has developed, it appears that an endorsement
    of the principles that OLC espouses would amount to adopting the absolute testimonial
    immunity for senior-level presidential aides by ipse dixit. Furthermore, because there
    are few, if any, well-formulated justifications for categorically excusing current and
    former senior-level presidential aides from responding to compelled congressional
    process, it would be difficult to do so consistent with existing case law, traditional
    norms of practice under our constitutional system of government, and common sense.
    3.     There Is No Principled Basis For Concluding That Senior-Level
    Presidential Aides Should Have Absolute Testimonial Immunity
    DOJ maintains that its contention that senior-level presidential aides should
    enjoy absolute testimonial immunity plainly follows from two related premises: (1) that
    the President himself has absolute testimonial immunity from compelled congressional
    process, and (2) that, as a derivative matter, so too must his “immediate advisors. . .
    with whom the President customarily meets on a regular or frequent basis.” (Def.’s
    Mot. at 60; see also Hr’g Tr. at 107:12-14 (acknowledging that DOJ is making “purely a
    derivative argument[,]” and that if the Court does not “think the President has absolute
    immunity, then that is a serious problem”).) In Miers, Judge Bates ably explains that
    both of these assumptions stand on shaky footing after United States v. Nixon, Clinton
    v. Jones, and Harlow v. Fitzgerald. See Miers, 
    558 F. Supp. 2d
    at 100–05. This Court
    agrees with Miers’s analysis, and it also observes that none of the differences that DOJ
    has highlighted between the instant case, on the one hand, and Clinton and Nixon, on
    102
    the other, actually matters. 30 The following brief observations further demonstrate that
    the proposition that senior-level presidential aides are entitled to absolute testimonial
    immunity has no principled justification, which further undermines DOJ’s assertion that
    such immunity must exist.
    First of all, the concept of absolute immunity from compelled congressional
    process cannot be gleaned from cases that endorse absolute testimonial immunity for
    legislators, or those that accept absolute immunity from civil damages for a variety of
    public officials. For example, DOJ’s reliance on Gravel v. United States, 
    408 U.S. 606
    (1972) is obviously misplaced, because legislative aides derive their absolute immunity
    from the Constitution’s provision of absolute testimonial immunity to congresspersons
    through the Speech and Debate Clause. See 
    id. at 615–17.
    As Miers explained, the
    Supreme Court in Harlow specifically addressed the argument that such immunity
    applies to senior-level executive aides, then concluded that, in contrast to legislative
    aides, senior-level executive aides are only entitled to qualified immunity.

    Nor can DOJ reasonably rely on the well-established body of case law that
    applies to the very different circumstance of immunity from civil damages. There are
    30
    DOJ attempts to distinguish the Clinton and Nixon cases on the grounds that those cases involved
    subpoenas issued in the context of a private, civil action for damages and in grand jury proceedings,
    respectively, while, here, what is at issue is a legislative subpoena. DOJ further contends that, in
    Nixon, live testimony by the President was not at issue. However, these distinctions are immaterial
    from the standpoint of the Supreme Court’s conclusion that, while presumptively important, a
    President’s confidentiality interests may sometimes be overridden over his objection. Furthermore, in
    this Court’s view, DOJ’s emphasis on the fact that what is at issue here is a legislative subpoena
    undercuts its argument, given the Supreme Court’s long-held reverence for Congress’s broad
    investigative authority. Where the law has not provided absolute immunity for Presidents who are
    facing significant civil damages lawsuits or who have criminal exposure (i.e., compelling claims to the
    need for confidentiality), it seems unlikely that a President would be declared absolutely immune from
    compelled congressional process.
    103
    reasons why courts have determined that judges, and legislators, and presidents cannot
    be held liable for civil damages for discretionary decisions that they make in the course
    of their duties. See, e.g., Forrester v. White, 
    484 U.S. 219
    , 225 (1988) (finding that
    absolute immunity from civil damages for judicial acts protects “the finality of
    judgments[,] discourage[es] inappropriate collateral attacks, [and] protect[s] judicial
    independence by insulating judges from vexatious actions prosecuted by disgruntled
    litigants” (citation omitted)); Nixon v. Fitzgerald, 
    457 U.S. 731
    , 751 (1982) (holding
    that the President is absolutely immune from civil damages due to “the singular
    importance of the President’s duties,” and that “diversion of his energies by concern
    with private lawsuits would raise unique risks to the effective functioning of
    government”); Tenney v. Brandhove, 
    341 U.S. 367
    , 375 (1951) (explaining that
    legislators “must be free to speak and act without fear of criminal and civil liability” as
    the reason for the absolute immunity endowed by the Speech and Debate Clause and
    similar provisions in “[f]orty-one of forty-eight State[]” constitutions); see also Imbler
    v. Pachtman, 
    424 U.S. 409
    , 424 (1976) (explaining the purpose of absolute immunity
    from civil damages for prosecutorial acts is to allow a prosecutor “to exercise his best
    judgment both in deciding which suits to bring and in conducting them in court”). And
    at least one of these justifications does not seem at all applicable to the reasons why
    one might have immunity from compelled congressional process. 31 One cannot simply
    31
    For example, in Mireles v. Waco, 
    502 U.S. 9
    (1991), the Supreme Court found that the district court
    had properly dismissed a case brought against a judge who had allegedly authorized police officers to
    use excessive force in seizing an individual because “a judicial officer, in exercising the authority
    vested in him, [must] be free to act upon his own convictions, without apprehension of personal
    consequences to himself.” 
    Id. at 10.
    By contrast, an executive branch official has no parallel
    expectation that he or she will not be called upon to testify about the operations of their offices.
    Indeed, Congress’s long standing and widely accepted power of inquiry, makes the potential for being
    questioned about one’s work an ever present possibility.
    104
    assume that the same rationale that compels the conclusion that those who hold certain
    civil functions are absolutely immune from civil damages necessitates absolute
    immunity from compelled congressional process, even for those same individuals.
    DOJ’s conception of absolute testimonial immunity for senior-level aides also
    turns out to be overbroad in application, which results in its imposing unwarranted
    societal costs. To understand why this is so, it is helpful to reflect on a hypothetical
    that the Court posed during the motions hearing. The Court posed to DOJ counsel a
    scenario in which an authorized House committee is interested in determining whether
    to appropriate special funding to improve the décor and the infrastructure-related
    working environment inside the White House. (Hr’g Tr. 124:8–20.) The committee
    wishes to evaluate the need for such additional funding, and it wants to talk to everyone
    who works there, and to compel this witness testimony, if needed. The Court asked
    DOJ counsel whether, if subpoenas issue, could the White House Counsel invoke
    absolute testimonial immunity to excuse the participation of senior-level presidential
    aides? (See id.)
    After engaging briefly with the Court in a humorous exchange about the
    Executive branch’s interest in addressing certain issues that currently exist with the
    White House (see 
    id. at 124:21–22),
    DOJ counsel responded that “the President would
    probably allow his most sensitive aides to go testify” but “if the person has testimonial
    immunity and the President has asserted it . . . then, yes, [the committee] wouldn’t be
    able to compel the person.” (Hr’g Tr. at 124:25–125:6.) Upon reflection, looking at it
    logically, one has to wonder why that is the case? Those aides’ status as senior-level
    assistants to the President seems irrelevant—i.e., when it comes to being asked about
    105
    the decor in the White House, either no White House worker should have to be bothered
    with Congress’s questions, or everyone who is called should have to appear. Therefore,
    the distinction between aides with heightened knowledge, access to the President, and
    special responsibilities (i.e., senior-level presidential aides) makes no difference where
    the topic of Congress’s investigation does not even conceivably implicate such
    distinction. Why, then, should senior-level presidential aides always get to play a
    special trump card with respect to such congressional requests? Judge Bates reflected
    on a similar concern in Miers, and DOJ has yet to explain why “Congress should be left
    with no recourse to obtain information that is plainly not subject to any colorable claim
    of executive privilege.” 
    Miers, 558 F. Supp. 2d at 106
    .
    On the other hand, if Congress seeks to explore with certain senior-level White
    House aides topics of a potentially sensitive nature, it is widely accepted that the
    President can exert executive privilege with respect to his aides’ answers, as
    appropriate, to protect any privileged information. 
    Miers, 225 F. Supp. 2d at 106
    .
    Given this, the question becomes why, then, would such senior-level aides need
    absolute immunity? In other words, even without a total exemption from compelled
    congressional process, senior-level White House aides can withhold the kinds of
    confidential and privileged information that distinguishes them from everybody else;
    they can do so by asserting an appropriate privilege if needed, when legislators ask
    questions that probe too deeply. Thus, it appears that absolute testimonial immunity
    serves only the indefensible purpose of blocking testimony about non-protected subjects
    106
    that are relevant to a congressional investigation and that such an aide would otherwise
    have a legal duty to disclose. 32
    Notably, this would appear to be the case even with respect to aides who, like
    White House Counsels, are “at the hub of all presidential activity.” (Def.’s Mot. at 69
    (internal quotation marks and citation omitted)). To be sure, White House Counsels and
    other similar aides have unfettered access to the President on a regular basis (see id.),
    and their roles with the Executive branch involve daily contact with copious amounts of
    information that is confidential in nature, including information that has been classified
    for our national security. (See Def.’s Mot. at 70 (emphasizing that “the role of the
    Counsel is to provide advice and assistance to the President and to carry out
    ‘responsibilities of utmost discretion and sensitivity’ on his behalf in all realms of
    domestic, military, and foreign affairs” (quoting 
    Fitzgerald, 457 U.S. at 749
    –50).) But
    DOJ has not persuasively explained why such access warrants absolute testimonial
    immunity, where such an individual would be counseled in any sworn communications
    with Congress, and would have ample opportunity to invoke executive privilege or any
    other lawful basis for withholding information, as needed to protect the legitimate
    interests of the Executive branch. And, of course, if such an aide cannot lawfully
    invoke any privilege to protect information in response to the committee’s questions,
    32
    DOJ suggests that there is something about Don McGahn’s former proximity to national security
    matters that warrants his immunity nonetheless. (Def.’s Mot. at 69, 73.) But it has not explained why
    this is so, given that such senior-level aides would certainly have the right to withhold information on
    the grounds of an applicable privilege, where appropriate. Thus, the fact that McGahn was “White
    House Counsel” and undoubtedly had exposure to “matters affecting the military, foreign affairs, and
    national security” (Def.’s Mot. at 64 (quotation marks and citation omitted)) does not provide an
    additional justification for a grant of absolute testimonial immunity under these circumstances. If what
    he knows can be lawfully withheld as covered by an applicable privilege, then the law will preclude its
    disclosure, even if he is compelled to testify in the absence of immunity. And if he cannot properly
    invoke the privilege, then there is no rational basis for maintaining that he should be immune to
    Congress’s questioning.
    107
    then there is no rational basis for maintaining that he should be immune from
    responding to Congress’s valid subpoena in the first place.
    It is also the case that the other rationale that such senior-level presidential aides
    might hope to rely on—‘I’m too busy’—is unavailable in the wake of the Supreme
    Court’s conclusion that even the President himself must find the time. See Miers, 
    558 F. Supp. 2d
    at 104. In any event, no such excuse could possibly apply to former senior-
    level aides, who have long departed from the White House, because such individuals no
    longer have proximity to power. What, then, justifies their right to be excused from the
    duty to respond to a call from Congress, especially when other private citizens have no
    choice? At a minimum, this perplexing question raises the following conceptual
    conundrum: if the purpose of providing certain senior-level presidential aides with
    absolute testimonial immunity is that the practicalities of their special roles demand it,
    then what justifies allowing that entitlement to follow them when they return to private
    life? As a matter of pure logic, it would seem that if one’s access to the Oval Office is
    the reason that a categorical exemption from compelled congressional process is
    warranted, then that trump card should, at most, be a raincheck, and not the lifetime
    pass that DOJ proposes.
    DOJ’s apparent response to the concern that absolute testimonial immunity for
    current and former senior-level aides serves no purpose is its suggestion in its briefs
    that such broad immunity serves three more systematic goals. First, it asserts that
    absolute testimonial immunity facilitates frank communications in the White House,
    and without it, the potential “public spectacle” of having to appear before a
    congressional committee “would surely exert influence over [senior-level aides’]
    108
    conduct in office, and could adversely affect the quality and candor of the counsel” that
    they offer to the President. (Def.’s Mot. at 70.) DOJ provides no evidence to support
    this representation. And it appears to contradict the lived experience of the many
    government officials who have testified before Congress, seemingly without
    consequence, over the years. See 
    Miers, 558 F. Supp. 3d at 102
    (observing that “the
    historical record produced by the Committee reveals that senior advisors to the
    President have often testified before Congress subject to various subpoenas dating back
    to 1973”).
    DOJ’s assertions about the chilling effect of compelled congressional process
    also imply that congressional questioning is needlessly intrusive and unwarranted, and
    that characterization drastically discounts the reasons why executive branch officials,
    including members of the President’s staff, are called to testify. As the Supreme Court
    has suggested on numerous occasions, Congress brings in witnesses not as punishment,
    but to provide the Legislature with the information that it needs to perform its critical
    legislative and oversight functions. 
    Watkins, 354 U.S. at 187
    ; 
    McGrain, 273 U.S. at 175
    . Thus, the idea that having to testify truthfully about the inner workings of
    government is a threat that would actually be sufficient to prevent key public servants
    from competently performing as assistants to the President seems anomalous.
    Moreover, if the institutions of our government are all, in fact, pushing in the same
    direction as they should be—i.e., toward developing and implementing policies that are
    in the best interests of the People of the United States—then the possibility that one of
    the public servants who work within the government might be called upon to cooperate
    with Congress, and thereby perform his public duty of giving authorized legislators the
    109
    means of performing their own constitutional functions, provides no reasonable grounds
    for fear. And if it does, as DOJ here suggests, then that is all the more reason why such
    testimony is critical. In short, DOJ’s implicit suggestion that compelled congressional
    process is a ‘zero-sum’ game in which the President’s interest in confidentiality
    invariably outweighs the Legislature’s interest in gathering truthful information, such
    that current and former senior-level presidential aides should be always and forever
    immune from answering probing questions, is manifestly inconsistent with a
    governmental scheme that can only function properly if its institutions work together.
    See The Federalist No. 51 (James Madison).
    DOJ’s second systematic concern is similarly discordant. DOJ insists that,
    without absolute testimonial immunity for senior-level presidential aides, the Executive
    branch would grind to a halt from the weight of the subpoenas that would be thrust
    upon it. (See Def.’s Mot. at 65.) This representation is plainly speculative.
    Furthermore, such speculation seems unreasonable, given two known facts. First of all,
    as DOJ itself admits, Congress has long demanded information from high-level
    members of the Executive branch, apparently without incident. See 
    Mazars, 940 F.3d at 721
    (noting that Presidents have “been the subjects of Congress’s legislative
    investigations” as far back as 1832, and that “fewer of these have required judicial
    intervention”). As the Supreme Court commented in Clinton v. Jones, the President’s
    “predictive judgment finds little support in either history or the relatively narrow
    compass of the issues raised in this particular case.” 
    Clinton, 520 U.S. at 702
    (citations
    omitted)); see also 
    id. (“As we
    have already noted, in the more than 200–year history of
    the Republic, only three sitting Presidents have been subjected to suits for their private
    110
    actions. If the past is any indicator, it seems unlikely that a deluge of such litigation
    will ever engulf the Presidency.”).
    In addition, as relevant here, we have a test case by which we can prove, or
    disprove, DOJ’s theory. The second significant fact is that it has been more than a
    decade since Judge Bates released the Miers decision, which plainly announced that
    senior-level presidential aides lack absolute immunity from compelled congressional
    process. Ironically, Miers itself observed that “[i]t is noteworthy that in an
    environment where there is no judicial support whatsoever for the Executive’s claim of
    absolute immunity, the historical record also does not reflect the wholesale compulsion
    by Congress of testimony from senior presidential advisors that the Executive fears.”
    Miers, 
    558 F. Supp. 2d
    at 102. And the absence of such history seems even more
    noteworthy at present. Surely if Congress was inclined to utilize its subpoena power to
    harass the Executive branch unjustifiably, then Miers’s own holding would have given
    it sufficient impetus to do so. Yet, even DOJ must acknowledge that no such parade of
    horribles has happened.
    DOJ’s third argument for the necessity of absolute testimonial immunity for
    systematic reasons places it back in the familiar refuge of its constitutional separation-
    of-powers contentions. In this regard, it maintains, that “the public spectacle of haling
    [current and] former advisors to a sitting President before a committee of Congress . . .
    promote[s] the perception of Executive subservience to the Legislature” (Def.’s Mot. at
    70), which, in its view of what the Constitution permits, is improper, because “[a]
    committee of Congress could not, consistent with the separation of powers, hale the
    President before it to compel him to testify under oath, any more than the President may
    111
    compel congressmen to appear before him” (Def.’s Mot. at 63). Here, once again, DOJ
    calls on separation-of-powers principles to do work that the Framers never intended.
    Indeed, the entire point of segregating the powers of a monarch into the three different
    branches of government was to give each branch certain authority that the others did not
    possess. Thus, while the branches might well be conceived of as co-equals (in the sense
    that one cannot unlawfully subvert the prerogatives of another), that does not mean that
    all three branches must be deemed to have the same powers. To the contrary, the
    President cannot hale members of Congress into the White House for questioning
    precisely because the power of inquiry resides with the Legislature, and also because
    the Constitution itself expressly prevents the Executive branch from becoming
    inquisitors by inflicting its own subpoena power on members of Congress for political
    reasons. 33
    Therefore, DOJ’s argument that the House of Representatives, which
    unquestionably possesses the constitutionally authorized power of inquiry and also the
    power of impeachment, should not be able to issue subpoenas to executive branch
    officials because the President cannot do the same to them, simultaneously appreciates
    traditional separation-of-powers principles and subverts them, and as such, truly makes
    no sense. See Miers, 
    558 F. Supp. 2d
    at 103 (explaining that the Executive branch’s
    33
    The Speech and Debate Clause mandates that members of the House and Senate and their aides “may
    not be made to answer—either in terms of questions or in terms of defending himself from
    prosecution—for the events that occurred” as part of the legislative process. See 
    Gravel, 408 U.S. at 614
    –16. The Constitution, therefore, makes legislators and their aides immune to the force of subpoena
    with respect to protected legislative activity. The Supreme Court has explained that the Speech and
    Debate Clause derives from a similar provision of the English Bill of Rights of 1689, which served to
    address successive monarchs’ use of “criminal and civil law to suppress and intimidate critical
    legislators.” See United States v. Johnson, 
    383 U.S. 169
    , 179 (1966). Thus, the purpose of the Speech
    and Debate Clause is to protect legislators from intimidating and/or hostile executive and judicial
    inquiry, a common abuse of power in seventeenth century England. See 
    id. at 181–82.
    And, notably,
    the Constitution includes nothing akin to the Speech and Debate Clause for the Executive branch.
    112
    separation-of-powers interest in “[p]residential autonomy, such as it is, cannot mean
    that the Executive's actions are totally insulated from scrutiny by Congress. That would
    eviscerate Congress's historical oversight function”).
    4.     Concluding That Presidential Aides Enjoy Absolute Testimonial
    Immunity At The President’s Discretion Conflicts With Core
    Constitutional Norms
    Finally, the Court turns to DOJ’s contention that, quite apart from the accepted
    ability of a President to invoke executive privilege to protect confidential information
    during the course of aides’ testimony before Congress, as a matter of law, it is the
    President who controls whether such aide provides any testimony whatsoever. During
    the motions hearing, DOJ’s counsel repeatedly emphasized that the power to invoke
    absolute testimonial immunity with respect to current and former senior-level aides
    belongs to the President. (See, e.g., Hr’g Tr. at 42:15–16 (“[T]he President owns the
    privilege here. So he is the owner of Mr. McGahn’s absolute immunity from
    compulsion[.]”), 43:4–6 (“[T]he President owns the privilege as to former officials with
    the same vigor with which he owns it to current officials.”), 125:5 (maintaining that
    immunity is “the President’s to assert”).) And when asked whether this power of the
    Executive is limited to such aides’ communications with Congress in particular, or also
    extends to preventing his aides from speaking to anyone else (e.g., the media) even
    after their departure from the White House, counsel indicated that while the Executive
    branch has “not taken a position on that,” it was “definitely not disclaiming that.” (Id.
    at 43:12–16.) This single exchange—which brings to mind an Executive with the power
    to oversee and direct certain subordinates’ communications for the remainder of their
    natural life—highlights the startling and untenable implications of DOJ’s absolute
    113
    testimonial immunity argument, and also amply demonstrates its incompatibility with
    our constitutional scheme.
    Stated simply, the primary takeaway from the past 250 years of recorded
    American history is that Presidents are not kings. See The Federalist No. 51 (James
    Madison); The Federalist No. 69 (Alexander Hamilton); 1 Alexis de Tocqueville,
    Democracy in America 115–18 (Harvey C. Mansfield & Delba Winthrop eds. & trans.,
    Univ. of Chicago Press 2000) (1835). This means that they do not have subjects, bound
    by loyalty or blood, whose destiny they are entitled to control. Rather, in this land of
    liberty, it is indisputable that current and former employees of the White House work
    for the People of the United States, and that they take an oath to protect and defend the
    Constitution of the United States. Moreover, as citizens of the United States, current
    and former senior-level presidential aides have constitutional rights, including the right
    to free speech, and they retain these rights even after they have transitioned back into
    private life.
    To be sure, there may well be circumstances in which certain aides of the
    President possess confidential, classified, or privileged information that cannot be
    divulged in the national interest and that such aides may be bound by statute or
    executive order to protect. But, in this Court’s view, the withholding of such
    information from the public square in the national interest and at the behest of the
    President is a duty that the aide herself possesses. Furthermore, as previously
    mentioned, in the context of compelled congressional testimony, such withholding is
    properly and lawfully executed on a question-by-question basis through the invocation
    114
    of a privilege, where appropriate. 34 As such, with the exception of the recognized
    restrictions on the ability of current and former public officials to disclose certain
    protected information, such officials (including senior-level presidential aides) still
    enjoy the full measure of freedom that the Constitution affords. Thus, DOJ’s present
    assertion that the absolute testimonial immunity that senior-level presidential aides
    possess is, ultimately, owned by the President, and can be invoked by the President to
    overcome the aides’ own will to testify, is a proposition that cannot be squared with
    core constitutional values, and for this reason alone, it cannot be sustained.
    * * *
    To make the point as plain as possible, it is clear to this Court for the reasons
    explained above that, with respect to senior-level presidential aides, absolute immunity
    from compelled congressional process simply does not exist. Indeed, absolute
    testimonial immunity for senior-level White House aides appears to be a fiction that has
    been fastidiously maintained over time through the force of sheer repetition in OLC
    opinions, and through accommodations that have permitted its proponents to avoid
    having the proposition tested in the crucible of litigation. And because the contention
    that a President’s top advisors cannot be subjected to compulsory congressional process
    simply has no basis in the law, it does not matter whether such immunity would
    theoretically be available to only a handful of presidential aides due to the sensitivity of
    34
    With respect to such withholding, the President can certainly identify sensitive information that he
    deems subject to executive privilege, United States v. 
    Nixon, 418 U.S. at 713
    , and his doing so gives
    rise to a legal duty on the part of the aide to invoke the privilege on the President’s behalf when, in the
    course of his testimony, he is asked a question that would require disclosure of that information. But
    the invocation of the privilege by a testifying aide is an order of magnitude different than DOJ’s
    current claim that the President essentially owns the entirety of a senior-level aide’s testimony such
    that the White House can order the individual not to appear before Congress at all.
    115
    their positions, or to the entire Executive branch. Nor does it make any difference
    whether the aides in question are privy to national security matters, or work solely on
    domestic issues. And, of course, if present frequent occupants of the West Wing or
    Situation Room must find time to appear for testimony as a matter of law when
    Congress issues a subpoena, then any such immunity most certainly stops short of
    covering individuals who only purport to be cloaked with this authority because, at
    some point in the past, they once were in the President’s employ. This was the state of
    law when Judge Bates first considered the issue of whether former White House
    Counsel Harriet Miers had absolute testimonial immunity in 2008, and it remains the
    state of law today, and it goes without saying that the law applies to former White
    House Counsel Don McGahn, just as it does to other current and former senior-level
    White House officials.
    Thus, for the myriad reasons laid out above as well as those that are articulated
    plainly in the prior precedents of the Supreme Court, the D.C. Circuit, and the U.S.
    District Court for the District of Columbia, this Court holds that individuals who have
    been subpoenaed for testimony by an authorized committee of Congress must appear for
    testimony in response to that subpoena—i.e., they cannot ignore or defy congressional
    compulsory process, by order of the President or otherwise. Notably, however, in the
    context of that appearance, such individuals are free to assert any legally applicable
    privilege in response to the questions asked of them, where appropriate.
    V.    CONCLUSION
    The United States of America has a government of laws and not of men. The
    Constitution and federal law set the boundaries of what is acceptable conduct, and for
    116
    this reason, as explained above, when there is a dispute between the Legislature and the
    Executive branch over what the law requires about the circumstances under which
    government officials must act, the Judiciary has the authority, and the responsibility, to
    decide the issue. Moreover, as relevant here, when the issue in dispute is whether a
    government official has the duty to respond to a subpoena that a duly authorized
    committee of the House of Representatives has issued pursuant to its Article I authority,
    the official’s defiance unquestionably inflicts a cognizable injury on Congress, and
    thereby, substantially harms the national interest as well. These injuries give rise to a
    right of a congressional committee to seek to vindicate its constitutionally conferred
    investigative power in the context of a civil action filed in court.
    Notably, whether or not the law requires the recalcitrant official to release the
    testimonial information that the congressional committee requests is a separate
    question, and one that will depend in large part on whether the requested information is
    itself subject to withholding consistent with the law on the basis of a recognized
    privilege. But as far as the duty to appear is concerned, this Court holds that Executive
    branch officials are not absolutely immune from compulsory congressional process—no
    matter how many times the Executive branch has asserted as much over the years—even
    if the President expressly directs such officials’ non-compliance.
    This result is unavoidable as a matter of basic constitutional law, as the Miers
    court recognized more than a decade ago. Today, this Court adds that this conclusion is
    inescapable precisely because compulsory appearance by dint of a subpoena is a legal
    construct, not a political one, and per the Constitution, no one is above the law. That is
    to say, however busy or essential a presidential aide might be, and whatever their
    117
    proximity to sensitive domestic and national-security projects, the President does not
    have the power to excuse him or her from taking an action that the law requires. Fifty
    years of say so within the Executive branch does not change that fundamental truth.
    Nor is the power of the Executive unfairly or improperly diminished when the Judiciary
    mandates adherence to the law and thus refuses to recognize a veto-like discretionary
    power of the President to cancel his subordinates’ legal obligations. To the contrary,
    when a duly authorized committee of Congress issues a valid subpoena to a current or
    former Executive branch official, and thereafter, a federal court determines that the
    subpoenaed official does, as a matter of law, have a duty to respond notwithstanding
    any contrary order of the President, the venerated constitutional principles that animate
    the structure of our government and undergird our most vital democratic institutions are
    preserved.
    Consequently, and as set forth in the accompanying Order, Plaintiff’s Motion for
    Expedited Partial Summary Judgment (ECF No. 22) is GRANTED, and Defendant’s
    Motion for Summary Judgment (ECF No. 32) is DENIED.
