    Before: SRINIVASAN, Chief Judge, HENDERSON, ROGERS,
    TATEL, GARLAND, GRIFFITH, MILLETT, PILLARD, WILKINS,
    KATSAS*, and RAO*, Circuit Judges.
    Opinion of the Court by Circuit Judge ROGERS.
    Dissenting opinion by Circuit Judge HENDERSON.
    Dissenting opinion by Circuit Judge GRIFFITH.
    ROGERS, Circuit Judge: The question before the en banc
    court is whether the Committee on the Judiciary of the House
    of Representatives has standing under Article III of the
    Constitution to seek judicial enforcement of its duly issued
    subpoena. Upon applying the principles of Article III standing,
    we hold that it does.
    The Constitution charges Congress with certain
    responsibilities, including to legislate, to conduct oversight of
    the federal government, and, when necessary, to impeach and
    remove a President or other Executive Branch official from
    office. Possession of relevant information is an essential
    precondition to the effective discharge of all of those duties.
    Congress cannot intelligently legislate without identifying
    national problems in need of legislative solution and relying on
    testimony and data that provide a deeper understanding of
    those problems, their origins, and potential solutions. It
    likewise cannot conduct effective oversight of the federal
    government without detailed information about the operations
    of its departments and agencies. And it cannot undertake
    impeachment proceedings without knowing how the official in
    * Judge Katsas and Judge Rao did not participate in this matter.
    4
    question has discharged         his   or   her    constitutional
    responsibilities.
    The Committee, acting on behalf of the full House of
    Representatives, has shown that it suffers a concrete and
    particularized injury when denied the opportunity to obtain
    information necessary to the legislative, oversight, and
    impeachment functions of the House, and that its injury would
    be redressed by the order it seeks from the court. The
    separation of powers and historical practice objections
    presented here require no different result. Indeed, the ordinary
    and effective functioning of the Legislative Branch critically
    depends on the legislative prerogative to obtain information,
    and constitutional structure and historical practice support
    judicial enforcement of congressional subpoenas when
    necessary.
    I.
    In March 2019, the House Judiciary Committee (“the
    Committee”) began an investigation into alleged misconduct
    by President Trump and his close advisors. See H. REP. NO.
    116-105, at 13 (2019). Its investigation followed upon
    publication of the report of Special Counsel Robert S. Mueller.
    See ROBERT S. MUELLER, III, REPORT ON THE INVESTIGATION
    INTO RUSSIAN INTERFERENCE IN THE 2016 PRESIDENTIAL
    ELECTION (2019). During his investigation, the Special
    Counsel interviewed Donald F. McGahn, II, then serving as
    White House Counsel. In declining to exonerate the President,
    the Special Counsel explained that the Office of Legal Counsel
    (“OLC”) in the Department of Justice had opined that indicting
    or criminally prosecuting a sitting President would violate the
    separation of powers. See
    id., vol. II at
    1. The Special
    Counsel’s Report accordingly concluded that impeachment
    would be the mechanism to address whether President Trump
    5
    impermissibly coordinated with the Russian government in
    connection with the 2016 Presidential election or obstructed
    justice in the course of the Special Counsel’s investigation. See
    id. The Committee’s investigation
    responded to this
    conclusion.
    The Committee’s interest in McGahn’s testimony
    therefore arose in furtherance of the “sole Power of
    Impeachment” vested in the House of Representatives under
    Article I, section 2, clause 5 of the Constitution, and included
    consideration of the amendment or enactment of laws on
    ethical conduct by Executive Branch officials and oversight of
    the Department of Justice (“the Department”) and the Federal
    Bureau of Investigation to determine if they were operating
    with requisite independence. Memorandum from Hon. Jerrold
    Nadler, Chairman, Comm. on the Judiciary, U.S. House of
    Representatives, to Members of the Committee, at 4–8 (July
    11, 2019) (hereinafter “Nadler Memorandum”); H. REP. NO.
    116-346, at 132–34, 159–60 & n.928 (2019); H. REP. NO. 116-
    105, at 13. The Committee requested that McGahn turn over
    documents related to the President’s alleged obstruction of the
    Special Counsel’s investigation. His testimony would, in turn,
    inform the Committee’s determination of whether President
    Trump had committed impeachable offenses in obstructing the
    Special Counsel’s investigation and whether to recommend
    articles of impeachment. McGahn’s testimony would also
    inform House oversight and legislative functions in
    determining the need for legislation to protect federal law
    enforcement investigations from improper political
    interference. Nadler Memorandum at 4–8; H. REP. NO. 116-
    346, at 132–34, 159–60 & n.928; H. REP. NO. 116-105, at 13.
    When McGahn, then no longer White House Counsel,
    declined these requests, the Committee issued a subpoena on
    April 22, 2019, ordering McGahn to appear at a May 21, 2019,
    6
    hearing to testify and to produce the requested documents. On
    May 20, McGahn’s successor as White House Counsel
    informed the Committee that the President had “directed Mr.
    McGahn not to appear at the Committee’s scheduled hearing”
    because the OLC had opined that close Presidential advisors
    were “absolutely immune from compelled congressional
    testimony.” Letter from Pat A. Cipollone, White House
    Counsel, to Hon. Jerrold Nadler, Chairman, Comm. on the
    Judiciary, U.S. House of Representatives, at 1–2 (May 20,
    2019). McGahn’s private counsel confirmed that he would not
    appear. Letter from William A. Burck to Hon Jerrold Nadler,
    Chairman, Comm. on the Judiciary, U.S. House of
    Representatives, at 1 (May 20, 2019).
    Although agreement was ultimately reached on the
    production of the subpoenaed documents, McGahn repeatedly
    rejected the Committee’s continuing offers of accommodations
    in attempting to secure his testimony. Finally, impasse having
    been reached, the Committee, as authorized by the House of
    Representatives in H. RES. 430, 116th Cong. (2019), filed suit
    in the federal district court on August 17, 2019, to enforce its
    subpoena. The complaint sought a declaratory judgment “that
    McGahn’s refusal to appear before the Committee in response
    to the subpoena issued to him was without legal justification”
    and an injunction “ordering McGahn to appear and testify
    forthwith before the Committee” “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.” Compl. at 53. The
    Department of Justice has represented McGahn in this
    litigation.
    The district court, in response to the parties’ cross-motions
    for summary judgment, ruled that the Committee had both
    standing and a cause of action to enforce its subpoena, and that
    7
    the court had subject matter jurisdiction over the lawsuit. On
    the merits, the district court rejected McGahn’s claim of
    absolute immunity from a congressional subpoena and directed
    him to appear before the Committee. Because McGahn might
    be entitled to withhold certain information on the basis of
    recognized privileges, the district court clarified that the
    injunction required McGahn only to appear before the
    Committee, not necessarily to answer any questions. Comm.
    on the Judiciary, U.S. House of Representatives v. McGahn,
    
    415 F. Supp. 3d 148
    , 214–15 (D.D.C. 2019).
    Upon McGahn’s appeal, a divided three-judge panel of
    this court held that the Committee lacked Article III standing
    because of separation-of-powers principles and historical
    practice.     Comm. on the Judiciary, U.S. House of
    Representatives v. McGahn, 
    951 F.3d 510
    (D.C. Cir. 2020).
    The court granted the Committee’s petition for en banc review
    to consider whether the Committee has standing to seek
    enforcement of its subpoena in federal court. Order at 2 (Mar.
    13, 2020).
    II.
    Article III of the Constitution vests in the federal judiciary
    “[t]he judicial power of the United States,” U.S. CONST. art. III,
    § 1, which extends to “[c]ases” and “[c]ontroversies,”
    id. § 2. “‘One
    element of the case-or-controversy requirement’ is that
    plaintiffs ‘must establish that they have standing to sue.’”
    Clapper v. Amnesty Int’l USA, 
    568 U.S. 398
    , 408 (2013)
    (quoting Raines v. Byrd, 
    521 U.S. 811
    , 818 (1997)). The
    standing inquiry is “[t]rained on whether the plaintiff is [a]
    proper party to bring [a particular lawsuit].” Ariz. State
    Legislature v. Ariz. Indep. Redistricting Comm’n, 
    135 S. Ct. 2652
    , 2663 (2015) (second and third alterations in original)
    (quoting 
    Raines, 521 U.S. at 818
    ). It “limits the category of
    8
    litigants empowered to maintain a lawsuit in federal court to
    seek redress for a legal wrong.” Spokeo v. Robbins, 
    136 S. Ct. 1540
    , 1547 (2016). When determining whether a plaintiff has
    Article III standing, the court must assume that the Committee
    will prevail on the merits. See Warth v. Seldin, 
    422 U.S. 490
    ,
    500 (1975); Estate of Boyland v. U.S. Dep’t of Agriculture, 
    913 F.3d 117
    , 123 (D.C. Cir. 2019). Because “reaching the merits
    of the dispute would force us to decide whether an action taken
    by one of the other two branches of the Federal Government
    was unconstitutional,” the court’s standing inquiry must be
    “especially rigorous.” 
    Raines, 521 U.S. at 819
    –20. Our
    analysis reflects that rigor.
    “[T]he ‘irreducible constitutional minimum’ of standing
    consists of three elements.” 
    Spokeo, 136 S. Ct. at 1547
    (quoting Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560
    (1992)). “The plaintiff must have (1) suffered an injury in fact,
    (2) that is fairly traceable to the challenged conduct of the
    defendant, and (3) that is likely to be redressed by a favorable
    judicial decision.”
    Id. At issue is
    injury in fact, “the ‘[f]irst
    and foremost’ of standing’s three elements.”
    Id. (alteration in original)
    (quoting Steel Co. v. Citizens for a Better
    Environment, 
    523 U.S. 83
    , 103 (1998)). “To establish injury
    in fact, a plaintiff must show that he or she suffered ‘an
    invasion of a legally protected interest’ that is ‘concrete and
    particularized’ and ‘actual or imminent, not conjectural or
    hypothetical.’”
    Id. at 1548
    (quoting 
    Lujan, 504 U.S. at 560
    ).
    These are distinct requirements: in addition to being actual or
    imminent, “an injury in fact must be both concrete and
    particularized.”
    Id. The Supreme Court
    has confirmed that these general
    principles of standing apply to institutional injuries claimed by
    legislative bodies. In Arizona State Legislature v. Arizona
    Independent Redistricting Commission, 
    135 S. Ct. 2652
                                    9
    (2015), the Supreme Court held that the Arizona State
    Legislature had standing to challenge as unconstitutional a
    ballot provision that vested redistricting authority in an
    independent agency. See
    id. at 26
    65–66. 
    Analyzing whether
    the legislature had demonstrated standing, the Court invoked
    its familiar standing test. See
    id. at 26
    63. 
    An institutional body
    seeking to demonstrate standing “‘must show, first and
    foremost,’ injury in the form of ‘“invasion of a legally
    protected interest” that is “concrete and particularized” and
    “actual or imminent.”’”
    Id. (quoting Arizonans for
    Official
    English v. Arizona, 
    520 U.S. 43
    , 64 (1997)). The first element
    of the test, injury in fact, thus applies to a legislative body
    seeking to demonstrate standing. The remainder of the test also
    applies: “[t]he Legislature’s injury must also be ‘fairly
    traceable to the challenged action’ and ‘redressable by a
    favorable ruling.’”
    Id. (quoting Clapper, 568
    U.S. at 409).
    We begin our analysis here, addressing these general
    principles of standing, before turning to the special
    considerations presented by the interbranch nature of this
    litigation. Ultimately, we hold that the Committee has Article
    III standing to protect against the denial of that to which it
    alleges it is entitled, namely McGahn’s testimony in response
    to its duly issued subpoena. McGahn’s disregard of the
    subpoena, the validity of which he has never challenged,
    deprived the Committee of specific information sought in the
    exercise of its constitutional responsibilities. The Committee
    is the “proper party” to bring this “particular lawsuit,”
    id. Because the Committee’s
    injury has been caused by McGahn’s
    defiance of its subpoena and can be cured here only by judicial
    enforcement of the subpoena, the injury is traceable to
    McGahn’s conduct and judicially redressable. And, contrary
    to McGahn’s positions, the Committee’s standing is consistent
    with the system of separated powers and capable of resolution
    10
    through the judicial process, see Allen v. Wright, 
    468 U.S. 727
    ,
    752 (1984).
    A.
    To be judicially cognizable and form the basis of Article
    III standing, an injury must be concrete, as opposed to abstract.
    A concrete injury is an injury that is real; it “must actually
    exist.” 
    Spokeo, 136 S. Ct. at 1548
    . “‘Concrete’ is not,
    however, necessarily synonymous with ‘tangible.’ Although
    tangible injuries are perhaps easier to recognize,” the Supreme
    Court has acknowledged “that intangible injuries can
    nevertheless be concrete.”
    Id. at 1549.
    As to the concreteness of the Committee’s alleged injury,
    the Supreme Court has acknowledged the essentiality of
    information to the effective functioning of Congress and long
    “held that each House has power ‘to secure needed
    information’” through the subpoena power. Trump v. Mazars
    USA, LLP, 
    140 S. Ct. 2019
    , 2031 (2020) (quoting McGrain v.
    Daugherty, 
    273 U.S. 135
    , 161 (1927)). Because Congress must
    have access to information to perform its constitutional
    responsibilities, when Congress “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
    . Therefore, “the power of inquiry — with
    process to enforce it — is an essential and appropriate auxiliary
    to the legislative function.”
    Id. at 174.
    “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
    , 160–61 (1955); see
    
    Mazars, 140 S. Ct. at 2031
    . That constitutional power entitles
    11
    each House to the testimony of a witness and production of
    requested documents in response to a lawful subpoena.
    The subpoena power is potent. Each House of Congress is
    specifically empowered to compel testimony from witnesses
    and the production of evidence in service of its constitutional
    functions, and the recipient of a subpoena is obligated by law
    to comply.
    It 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 v. United States, 
    354 U.S. 178
    , 187–88 (1957); see
    
    Mazars, 140 S. Ct. at 2036
    (quoting 
    Watkins, 354 U.S. at 187
    ).
    The power of each House of Congress to compel witnesses
    to appear before it to testify and to produce documentary
    evidence has a pedigree predating the Founding and has long
    been employed in Congress’s discharge of its primary
    constitutional responsibilities: legislating, conducting
    oversight of the federal government, and, when necessary,
    checking the President through the power of impeachment.
    Congressional subpoenas have their historical basis in the
    “emergence of [the English] Parliament.” 
    Watkins, 354 U.S. at 188
    . Congress began using its investigative powers from the
    earliest days of the Republic to investigate national problems
    and probe for possible federal solutions. See Mazars, 140 S.
    Ct. at 2029–30. Yet “[t]he Nation was almost one hundred
    years old before the first case reached [the Supreme] Court to
    12
    challenge the use of compulsory process as a legislative
    device.” 
    Watkins, 354 U.S. at 193
    . In that case, Kilbourn v.
    Thompson, 
    103 U.S. 168
    (1881), the Supreme Court held that
    the House had “exceeded the limit of its own authority” by
    inquiring into a matter that “could result in no valid legislation
    on the subject to which the inquiry referred.”
    Id. at 192, 195.
    Congress’s power to issue subpoenas in conjunction with
    legislative investigations was confirmed by the Supreme Court
    in McGrain, 
    273 U.S. 135
    , and Sinclair v. United States, 
    279 U.S. 263
    (1929). “Following these important decisions, . . .
    there was vigorous use of the investigative process by a
    Congress bent upon harnessing and directing the vast economic
    and social forces of the times.” 
    Watkins, 354 U.S. at 195
    .
    Congress commonly uses subpoenas not only to develop
    legislation but also in furtherance of its oversight of the federal
    government, including the Executive Branch. This subpoena
    power “comprehends probes into departments of the Federal
    Government to expose corruption, inefficiency or waste.”
    
    Watkins, 354 U.S. at 187
    . Subject to certain restraints, see, e.g.
    , id., “[a] legislative inquiry
    may be as broad, as searching, and
    as exhaustive as is necessary to make effective the
    constitutional powers of Congress,” Townsend v. United
    States, 
    95 F.2d 352
    , 361 (D.C. Cir. 1938). Indeed, the Court
    has recently emphasized that “[u]nless Congress have and use
    every means of acquainting itself with the acts and the
    disposition of the administrative agents of the government, the
    country must be helpless to learn how it is being served.”
    
    Mazars, 140 S. Ct. at 2033
    (quoting United States v. Rumely,
    
    345 U.S. 41
    , 43 (1953)).
    The House of Representatives employs its subpoena power
    in service of its constitutional power of impeachment, as the
    Committee’s investigation illustrates. The Constitution vests
    in the House of Representatives the “sole Power of
    13
    Impeachment,” U.S. CONST. art. I, § 2, cl. 5, and thereby
    empowers the House to set in motion a process that may result
    in the removal of the President from Office. To level the grave
    accusation that a President may have committed “Treason,
    Bribery, or other high Crimes and Misdemeanors,” U.S.
    CONST. art. II, § 4, the House must be appropriately informed.
    And it cannot fully inform itself without the power to compel
    the testimony of those who possess relevant or necessary
    information. As far back as 1796, George Washington, the
    Nation’s first President, acknowledged that the House may
    compel the President to turn over some Executive Branch
    information if sought as part of an impeachment investigation.
    See Pres. George Washington, Message to the House
    Regarding Documents Relative to the Jay Treaty (Mar. 30,
    1796); see 
    Mazars, 140 S. Ct. at 2029
    –30. Decades later,
    Congress also issued subpoenas to President Nixon during its
    impeachment investigation of him. See Senate Select Comm.
    on Presidential Campaign Activities v. Nixon, 
    498 F.2d 725
    ,
    726–27 (D.C. Cir. 1974).
    The House, then, has a long-recognized right, based in the
    Constitution, to have McGahn appear to testify and produce
    documents. Because each House of Congress delegates its
    power of inquiry to its Committees, which are “endowed with
    the full power of Congress to compel testimony,” 
    Watkins, 354 U.S. at 201
    ; HOUSE RULES X & XI, cl. 2(m)(1), the Committee
    exercised the House’s subpoena power when it issued a
    subpoena to McGahn. By refusing to testify in response to the
    Committee’s concededly valid subpoena, McGahn has denied
    the Committee something to which it alleges it is entitled by
    law. And because the Committee has alleged the deprivation
    of testimony to which it is legally entitled, its asserted injury is
    concrete.
    14
    In other contexts, as well, the Supreme Court has held that
    when a person seeks to obtain information the government is
    required to disclose, the denial of the information is a concrete
    injury for standing purposes. For example, in FEC v. Akins,
    
    524 U.S. 11
    (1998), the Court held that the plaintiffs had
    suffered an Article III injury “consist[ing] of their inability to
    obtain information . . . that, on their view of the law,” they
    were legally entitled to.
    Id. at 21
    . 
    Similarly, in Public Citizen
    v. DOJ, 
    491 U.S. 440
    (1989), the Court held that plaintiffs
    incurred an injury sufficient to support standing when they
    were denied access to agency records to which they were
    legally entitled.
    Id. at 449.
    Akins and Public Citizen thereby
    support the principle that the denial of information to which the
    plaintiff claims to be entitled by law establishes a quintessential
    injury in fact. See Shays v. FEC, 
    528 F.3d 914
    , 923 (D.C. Cir.
    2008). Here, each House of the Congress has a constitutionally
    grounded entitlement to obtain information, namely McGahn’s
    testimony, in carrying out its constitutional functions.
    McGahn’s denial of the information to which the Committee
    alleges it is entitled results in informational injury of the kind
    that the Supreme Court held supported standing in Akins and
    Public Citizen.
    By analogy, private parties undeniably have standing to
    seek judicial enforcement of compliance with subpoenas. And
    Courts have regularly entertained lawsuits in which a
    legislative body seeks to enforce a subpoena against a private
    party. See, e.g., In re Application of Senate Permanent
    Subcomm. on Investigations, 
    655 F.2d 1232
    (D.C. Cir. 1981);
    Senate Select Comm., 
    498 F.2d 725
    ; Senate Permanent Comm.
    v. Ferrer, 
    199 F. Supp. 3d 125
    (D.D.C. 2016). Further, the
    OLC, in opinions never withdrawn, has stated that a House of
    Congress can file a civil action to seek enforcement of its
    subpoenas. See Response to Congressional Requests for
    Information Regarding Decisions Made Under the
    15
    Independent Counsel Act, 
    10 Op. O.L.C. 68
    , 83 (1986)
    (“Cooper Opinion”); 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 (1984) (“Olson
    Opinion”). A legislative body, then, generally has standing to
    sue to obtain information it claims it has been wrongfully
    denied, at least when a private party is withholding
    information. McGahn maintains the result is different when
    the defendant withholding the information is another branch of
    government, but the reasons he offers do not explain why the
    identity of the defendant should make a difference for purposes
    of standing, which is focused on whether the plaintiff is the
    proper party to bring the lawsuit. See Part III infra.
    In sum, by virtue of the House’s long-recognized subpoena
    power, the Committee was entitled to McGahn’s testimony
    pursuant to its duly issued subpoena, which he has never
    challenged, and the specific information the Committee would
    learn therefrom in connection with carrying out its
    constitutional duties. By defying the subpoena, McGahn has
    deprived the Committee of that testimony and that deprivation
    is a concrete injury.
    B.
    The Committee’s asserted injury must be not only concrete
    but also particularized. “For an injury to be ‘particularized,’ it
    ‘must affect the plaintiff in a personal and individual way.’”
    
    Spokeo, 136 S. Ct. at 1548
    (quoting 
    Lujan, 504 U.S. at 560
    n.1).
    An injury is not particularized if it is “undifferentiated” and
    “‘common to all members of the public.’” United States v.
    Richardson, 
    418 U.S. 166
    , 177 (1974) (quoting Ex parte Levitt,
    
    302 U.S. 633
    , 634 (1937)). The injury, in short, must be
    specific to the plaintiff.
    16
    Virginia House of Delegates v. Bethune-Hill, 
    139 S. Ct. 1945
    (2019), provides some guidance on particularization
    when a legislative institution seeks to show injury in fact. In
    that case, the Virginia House of Delegates sought to appeal the
    judicial invalidation of a redistricting plan in whose enactment
    it had participated.
    Id. at 1950.
    But the Virginia legislature
    was composed of two houses: the Senate and the House of
    Delegates. See
    id. at 1949.
    And the interest that the House of
    Delegates asserted — in defending the validity of a
    redistricting plan that it had approved — was shared with the
    Senate. See
    id. at 1953.
    Thus, to the extent that judicial
    invalidation of legislation constituted an injury in fact, the
    House of Delegates as one half of a bicameral legislature was
    not an appropriate party to vindicate that injury. Rather, to
    challenge the judicial invalidation, the Senate and House of
    Delegates would have needed to act together, akin to the
    circumstances of Arizona State Legislature, “in which the
    Court recognized the standing of the Arizona House and Senate
    — acting together — to challenge a referendum.”
    Id. at 1953.
    What undermined the House of Delegates’ attempt to show
    standing was the “mismatch between the body seeking to
    litigate and the body to which the relevant [state] constitutional
    provision allegedly assigned . . . authority.”
    Id. Although not explicitly
    couched in terms of particularization, the Court’s
    focus on “mismatch” is an inquiry into whether the claimed
    injury is personal to the plaintiff or else shared by a larger
    group of which the plaintiff is only a component — in other
    words, whether the injury is particularized.
    The Committee’s asserted injury is particularized because
    the Committee “is an institutional plaintiff asserting an
    institutional injury,” Ariz. State 
    Legislature, 135 S. Ct. at 2664
    .
    There is no “mismatch” here, Va. House of Delegates, 139 S.
    Ct. at 1953: the body whose informational and investigative
    prerogatives have been infringed is the body authorized by
    17
    House Resolution 430 to bring the present lawsuit. The power
    to issue a subpoena “may be exercised by a committee acting .
    . . on behalf of one of the Houses” of Congress. Eastland v.
    U.S. Servicemen’s Fund, 
    421 U.S. 491
    , 505 (1975). The full
    House of Representatives has delegated its subpoena authority
    to its Committees, empowering each Committee “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, cl. 2(m)(1). A House
    Committee that issues a subpoena, including the Committee on
    the Judiciary, thus exercises the subpoena power of the full
    House.
    The House Judiciary Committee has issued the McGahn
    subpoena on behalf of, and with the authorization of, the full
    House of Representatives. There is no dispute that the House
    as an institution may unilaterally obtain what its authorized
    Committee seeks to compel here: McGahn’s testimony. The
    Senate naturally need not sign off on the House’s subpoenas;
    so it need not join efforts to vindicate them in the courts.
    Because the Committee exercised the investigative authority of
    the full House, the Committee was entitled to McGahn’s
    testimony. Denial of his testimony is a deprivation that is a
    concrete injury and because the plaintiff is the distinctly injured
    party, the injury is particularized.
    The House of Representatives has a unique interest under
    the Constitution in vindicating this injury. The Constitution
    places in the House sole responsibility to determine whether to
    file articles of impeachment against the President. U.S. CONST.
    art. 1, § 2, cl. 5. The subpoena power of the House exercised
    by the Committee in subpoenaing McGahn relates directly to
    that responsibility. The House’s other constitutional functions
    of legislation and oversight are also handicapped by McGahn’s
    18
    defiance of the subpoena, as explained in the Nadler
    Memorandum. Because of delegations pursuant to House
    Rules and passage of a House Resolution authorizing the
    present lawsuit, the Committee is an appropriate plaintiff to
    vindicate that injury.
    C.
    The remaining two prongs of the traditional standing test
    — that the injury is “fairly traceable to the challenged conduct”
    and “is likely to be redressed by a favorable [judicial]
    decision,” Va. House of 
    Delegates, 139 S. Ct. at 1950
    — are
    readily met. The injury that the Committee asserts has been
    directly caused by McGahn’s conduct that it seeks to have
    enjoined. McGahn’s refusal to testify before the Committee in
    response to a valid subpoena is responsible for the denial of
    information to which the Committee claims it is entitled and
    the resulting handicapping of the House’s discharge of its
    constitutional obligations that the Committee now seeks to
    remedy in this lawsuit.
    The injury is also likely to be redressed by a favorable
    judicial decision. The Committee’s lawsuit seeks “declaratory
    and injunctive relief” “[d]eclar[ing] that McGahn’s refusal to
    appear before the Committee in response to the subpoena
    issued to him was without legal justification” and “ordering
    McGahn to appear and testify forthwith before the
    Committee.” Compl. at 53. If the court grants the Committee
    that relief, the deprivation that the Committee has suffered will
    be remedied. The Committee has therefore demonstrated
    redressability.
    19
    III.
    The present lawsuit, brought by a Committee of the House
    of Representatives against a former White House Counsel,
    implicates considerations not always present in a standing
    dispute. McGahn contends that under Raines v. Byrd, 
    521 U.S. 811
    , separation of powers analysis prevents judicial airing and
    resolution of interbranch informational disputes like this one.
    Additionally, he views Raines itself, in particular its emphasis
    on history, to bar the present lawsuit. Each line of argument
    asserts a structural barrier to judicial involvement in
    informational disputes between the elected branches. With
    notable exceptions dating back at least to the 1970s, Congress
    and the Executive have “managed for over two centuries to
    resolve [informational] disputes among themselves.” 
    Mazars, 140 S. Ct. at 2031
    . That “longstanding practice . . . imposes on
    us a duty of care to ensure that we not needlessly disturb ‘the
    compromises and working arrangements that [those] branches
    . . . themselves have reached.’”
    Id. (second and third
    alterations
    in original) (quoting NLRB v. Noel Canning, 
    573 U.S. 513
    ,
    524–26 (2014)). Our analysis demonstrates that holding the
    Committee has Article III standing involves no such
    disturbance.
    A.
    “[T]he law of Art[icle] III standing is built on a single
    basic idea — the idea of separation of powers.” 
    Raines, 521 U.S. at 820
    (quoting 
    Allen, 468 U.S. at 752
    ). In turn, “federal
    courts may exercise power . . . only when adjudication is
    ‘consistent with a system of separated powers,’” 
    Allen, 468 U.S. at 752
    (quoting Chi. & Grand Trunk Ry. Co. v. Wellman,
    
    143 U.S. 339
    , 345 (1892)). The court’s standing analysis has
    accounted for and ensured the federal judiciary’s limited
    constitutional role, and the court does not act outside its
    20
    “properly limited . . . role,” 
    Warth, 422 U.S. at 498
    , in holding
    that the Committee has standing. But McGahn maintains that
    in exercising jurisdiction over the present lawsuit and resolving
    whether he is required to testify, the court takes sides in an
    interbranch dispute, aggrandizes Congress at the expense of the
    Executive, or otherwise disrupts the balance of powers between
    the Branches. To the contrary, the judiciary, in exercising
    jurisdiction over the present lawsuit, does not arrogate any new
    power to itself at the expense of either of the other branches but
    rather plays its appropriate constitutional role.
    1.
    At the outset, there is reason for some skepticism
    regarding the foundation of McGahn’s contention that all of the
    separation of powers objections he raises bear on whether the
    Committee has Article III standing. After all, as the Supreme
    Court has long emphasized, “the requirement of standing
    ‘focuses on the party seeking to get his complaint before a
    federal court and not on the issues he wishes to have
    adjudicated.’” Valley Forge Christian Coll. v. Ams. United for
    Separation of Church & State, Inc., 
    454 U.S. 464
    , 484 (1982)
    (quoting Flast v. Cohen, 
    392 U.S. 83
    , 99 (1968)). The
    statement in 
    Raines, 521 U.S. at 820
    , that separation of powers
    was the “single basic idea” on which standing is based,
    appropriately reflects the “overriding and time-honored
    concern about keeping the Judiciary’s power within its proper
    constitutional sphere.” It does not mean, as McGahn
    maintains, that merely invoking separation of powers
    principles defeats standing in interbranch disputes like this one.
    Not every separation of powers concern — including some that
    McGahn raises here — implicates the separation of powers
    principle underlying the standing doctrine, namely confining
    the judiciary to its proper role. And in any event, the separation
    of powers objections McGahn raises do not withstand analysis
    21
    and are therefore unpersuasive. Moreover, other separation of
    powers doctrines not before the en banc court, including the
    non-justiciability of political questions, separately address
    whether the court should decline to reach the merits of
    interbranch disputes. See Baker v. Carr, 
    369 U.S. 186
    (1962).
    McGahn points to Chenoweth v. Clinton, 
    181 F.3d 112
    (D.C. Cir. 1999), where this court stated that it understood itself
    to be “require[d] . . . to merge our separation of powers and
    standing analyses.”
    Id. at 116.
    On its face, that statement
    appears to support the position that all of the separation of
    powers objections that McGahn raises bear on the issue of the
    Committee’s standing. Yet in Chenoweth, the court was
    considering only whether individual Members of the House of
    Representatives had standing to sue the President to enjoin the
    implementation of a Presidential initiative. The court stated
    that in the past it had dismissed such individual legislator
    lawsuits not on standing grounds but rather on the basis of
    “‘circumscribed equitable discretion,’” under which “the court
    would decline to hear the complaint of a Congressman who
    ‘could obtain substantial relief from his fellow legislators.’”
    Id. at 114
    (quoting Riegle v. Federal Open Market Comm., 
    656 F.2d 873
    , 881 (D.C. Cir. 1981)). The separation of powers
    consideration that the court viewed as being a necessary part of
    its standing analysis was the need for the judiciary to “avoid
    ‘meddl[ing] in the internal affairs of the legislative branch,’”
    id. at 116
    (alteration in original) (quoting Moore v. U.S. House
    of Representatives, 
    733 F.2d 946
    , 956 (D.C. Cir. 1984)), by
    entertaining a lawsuit by an individual legislator whose “rights
    [could] be vindicated by congressional repeal of the
    [offending] statute,’”
    id. at 115
    (alterations in original)
    (quoting 
    Moore, 733 F.2d at 956
    ). It is this limited separation
    of powers concern, in the context of individual legislator suits
    and not implicated here, that Chenoweth stated must be part of
    the standing analysis.
    22
    So too in Arizona State Legislature, the Supreme Court
    stated that “a suit between Congress and the President would
    raise separation-of-powers concerns absent” in that case, which
    involved a state legislative body. Ariz. State 
    Legislature, 135 S. Ct. at 2665
    n.12. The Court did not hold that such concerns
    should be considered separately to preclude a legislative body’s
    lawsuit against the Executive Branch but rather emphasized its
    directive from Raines for a standing analysis that is
    “‘especially rigorous when reaching the merits of the dispute
    would force [the Court] to decide whether an action taken by
    one of the other two branches of the Federal Government was
    unconstitutional.’” Id. (quoting 
    Raines, 521 U.S. at 819
    –20).
    Because the Committee has identified a concrete injury,
    namely a former Executive Branch official’s defiance of a valid
    subpoena, and is the institution duly authorized to maintain the
    present lawsuit, the obstacles to suits by individual legislators
    are inapplicable.
    This court, however, need not resolve whether Raines,
    Chenoweth, or Arizona State Legislature stands for the
    proposition that any objection that falls within the broad ambit
    of “separation of powers” may defeat a plaintiff’s standing
    because none of McGahn’s separation of powers objections to
    the Committee’s standing is persuasive.
    The Supreme Court’s recent decision in Trump v. Mazars
    USA, LLP elaborates on the separation of powers concerns
    where Congress and the President are at odds over information.
    The Court stated because “Congress and the President have an
    ongoing institutional relationship as the ‘opposite’ and ‘rival’
    political branches established by the Constitution, . . .
    congressional subpoenas directed at the President differ
    markedly” from those issued to private parties. Mazars, 140 S.
    Ct. at 2033–34 (quoting FEDERALIST NO. 51 (J. Madison)).
    23
    That is, “congressional subpoenas for the President’s
    information unavoidably pit the political branches against one
    another” and represent “a clash between rival branches of
    government over [testimony] of intense political interest for all
    involved.”
    Id. at 2034.
    Mazars addressed the merits of a
    challenge to the validity of a congressional subpoena, not the
    plaintiff’s standing, but the concerns about the adjudication of
    such interbranch disputes expressed in Mazars may be
    implicated here. Such concerns do not bar the Committee’s
    standing, however. Much of the Supreme Court’s attention
    was directed to the implications of a “limitless” congressional
    subpoena power that “would transform the ‘established
    practice’ of the political branches.”
    Id. at 16
    (quoting Noel
    
    Canning, 573 U.S. at 524
    ). This court explains in responding
    to McGahn’s separation of powers objections, see Part III.A.2
    infra, why allowing the Committee to proceed with the present
    lawsuit would preserve, rather than disrupt, that historical
    practice of accommodation. Furthermore, McGahn has never
    challenged the validity of the Committee’s subpoena.
    2.
    McGahn begins his separation of powers objections by
    maintaining that if the Committee has standing, then Congress
    will have been provided “a blueprint for extensive expansion
    of the legislative power’ by allowing Congress to ‘arrogate
    power to itself,’” empowering Congress to unilaterally resolve
    informational disputes without engaging in the historical
    practice of negotiating informational disputes with the
    Executive Branch. Appellant Br. at 24–25 (quoting Free Enter.
    Fund v. Public Co. Accounting Oversight Bd., 
    561 U.S. 477
    ,
    500 (2010)). Courts must take care not to disrupt the
    “longstanding practice” of accommodation between the
    political branches. 
    Mazars, 140 S. Ct. at 2031
    . But there is no
    congressional “arrogation” of power here and no threat that the
    24
    court’s decision will disrupt the historical practice of
    accommodation. To the contrary, permitting Congress to bring
    this lawsuit preserves the power of subpoena that the House of
    Representatives is already understood to possess. Rather, it is
    McGahn’s challenge to the Committee’s standing that seeks to
    alter the status quo ante and aggrandize the power of the
    Executive Branch at the expense of Congress.
    For more than forty years this circuit has held that a House
    of Congress has standing to pursue a subpoena enforcement
    lawsuit in federal court. See Comm. on Oversight & Gov’t
    Reform v. Holder, 
    979 F. Supp. 2d 1
    , 20–22 (D.D.C. 2013);
    Comm. on the Judiciary, U.S. House of Representatives v.
    Miers, 
    558 F. Supp. 2d 53
    , 68–78 (D.D.C. 2008); United States
    v. AT&T, 
    551 F.2d 384
    , 391 (D.C. Cir. 1976); Senate Select
    
    Comm., 498 F.2d at 728
    ; see also Part III.B.2 infra. McGahn
    does not suggest that any court, prior to the vacated panel
    majority in the present case, has ever ruled to the contrary.
    Congress and the Executive Branch have long operated under
    the assumption that Congress may, if necessary, seek
    enforcement of a subpoena in federal court.
    Accepting McGahn’s position that the Committee lacks
    standing would significantly curtail the possibility of
    accommodation. That outcome would upset settled
    expectations and dramatically alter bargaining positions in the
    accommodation process over informational disputes in the
    future. Without the possibility of enforcement of a subpoena
    issued by a House of Congress, the Executive Branch faces
    little incentive to reach a negotiated agreement in an
    informational dispute. Indeed, the threat of a subpoena
    enforcement lawsuit may be an essential tool in keeping the
    Executive Branch at the negotiating table. For example,
    President Clinton and a Senate subcommittee “[e]ventually . . .
    reached an agreement” over an informational dispute only after
    25
    “a Senate threat to seek judicial enforcement of the subpoena.”
    
    Mazars, 140 S. Ct. at 2030
    . Without that possibility, Presidents
    could direct widescale non-compliance with lawful inquiries
    by a House of Congress, secure in the knowledge that little can
    be done to enforce its subpoena — as President Trump did here.
    See Letter from Pat A. Cipollone, White House Counsel, to
    Hon. Nancy Pelosi, Speaker of the House, et al., at 7 (Oct. 8,
    2019). Traditional congressional oversight of the Executive
    Branch would be replaced by a system of voluntary
    Presidential disclosures, potentially limiting Congress to
    learning only what the President wants it to learn. And the
    power of impeachment, the “essential check . . . upon the
    encroachments of the executive,” FEDERALIST NO. 66 (A.
    Hamilton), would be diminished because a President would be
    unlikely to voluntarily turn over information that could lead to
    impeachment.
    Neither does holding that the Committee has Article III
    standing displace the historical practice of accommodation, as
    McGahn maintains. Litigation, as the General Counsel to the
    Committee emphasized to this court during oral argument, is
    not a preferred option of politicians. See En Banc Oral Arg.
    Tr. at 121–22. The subpoena to McGahn was issued over 15
    months ago and litigation over its enforcement continues. A
    Congress lasts for only two years, see U.S. CONST. art. I, § 2,
    cl. 1;
    id. amend. XX, §
    1, and the current Congress may expire
    before the House of Representative can complete the present
    litigation and obtain judicial enforcement of its subpoena.
    Despite the Committee’s subpoena of McGahn in regard to its
    investigation pursuant to the House’s “sole Power of
    Impeachment,” U.S. CONST. art. I, § 2, cl. 5, and its continuing
    efforts to reach accommodations for McGahn to testify, the
    President refused to permit McGahn to testify, see Cipollone
    Letter of May 20, 2019, to Chairman Nadler, at 1–2, and
    subsequently refused to allow any member of the Executive
    26
    Branch to cooperate with the Committee’s investigation, see
    Cipollone Letter of Oct. 8, 2019, to Speaker Pelosi, at 7. In
    such circumstances, where there is an impasse contrary to
    traditional norms, no practicable alternative to litigation exists.
    That result stems not from the court’s holding that the
    Committee has standing to seek judicial enforcement of its
    subpoena, but from a rare breakdown in the accommodation
    process itself. The parties’ historical responsibility to engage
    in negotiations to resolve their interbranch informational
    disputes, see United States v. AT&T, 
    567 F.2d 121
    , 127 (D.C.
    Cir. 1977), remains unaffected by holding that the Committee
    has Article III standing.
    McGahn next maintains that resolving this interbranch
    dispute would constitute a judicial arrogation of power at the
    expense of Congress and the Executive, which ought to resolve
    it themselves. “In order to remain faithful to [the federal
    government’s] tripartite structure, the power of the Federal
    Judiciary may not be permitted to intrude upon the powers
    given to the other branches.” 
    Spokeo, 136 S. Ct. at 1547
    . But
    by permitting the Committee to bring a lawsuit in federal court
    to enforce its subpoena, the court is not enlarging the power or
    prerogatives of the federal judiciary. To the contrary, subpoena
    enforcement is a “familiar judicial exercise,” Zivotofsky ex rel.
    Zivotofsky v. Clinton, 
    566 U.S. 189
    , 196 (2012), a not unusual
    corollary to civil litigation. The Federal Rules of Civil
    Procedure authorize a party to issue, under the auspices of the
    court, a subpoena ordering testimony, document production, or
    production of other tangible objects. See FED. R. CIV. P. 45(a).
    Upon objection by the recipient of such a civil subpoena that
    compliance would require the disclosure of privileged matter,
    a motion requesting that the court quash the subpoena would
    be available. See FED. R. CIV. P. 45(e)(2). The court must
    quash or modify the subpoena if it determines that the subpoena
    “requires disclosure of privileged or other protected matter.”
    27
    FED. R. CIV. P. 45(d)(3). When the party has no valid grounds
    for objecting, the court may enforce the subpoena by holding
    in contempt a person who refuses to obey it. See FED. R. CIV.
    P. 45(g). Thus, the precise function that the Committee asks
    the court to perform, namely determining whether McGahn has
    a valid excuse for refusing to appear and testify before the
    Committee and compelling his compliance with its subpoena if
    he does not, is a traditional feature of civil litigation in federal
    court.
    Further, contrary to McGahn’s assertion, the court does
    not impermissibly take sides in an interbranch dispute by
    holding that the Committee has standing and resolving whether
    or not McGahn is required to appear and testify. What the
    Committee seeks through its subpoena enforcement lawsuit is
    resolution of a discrete and limited legal issue: whether
    McGahn must appear before it to testify, absent invocation of
    a valid privilege that would excuse his refusal to answer
    specific questions. Given McGahn’s previous role as a close
    presidential advisor, it is plausible that Executive privilege
    could be properly asserted in response to at least some of the
    Committee’s questions, depending on their substance. See
    generally United States v. Nixon, 
    418 U.S. 683
    , 705 (1974).
    Such a potentially available privilege is a powerful protection
    of the President’s interest in Executive Branch confidentiality,
    and it remains unaffected by an order compelling McGahn to
    appear and testify before the Committee. Consequently,
    entertaining the Committee’s subpoena enforcement lawsuit
    does not raise the specter that the judiciary is taking sides in an
    interbranch dispute. A court is not normally understood to be
    taking sides when it enforces a subpoena in civil litigation, and
    McGahn points to nothing to support a contrary conclusion
    here.
    28
    McGahn also maintains that exercising jurisdiction would
    impede the Executive in the performance of its constitutional
    responsibilities because only the Executive Branch is
    constitutionally empowered to “conduct[] civil litigation in the
    courts of the United States for vindicating public rights,”
    Buckley v. Valeo, 
    424 U.S. 1
    , 140 (1976). The traditional
    means of enforcing congressional subpoenas, according to
    McGahn, has been through the criminal contempt statute, 2
    U.S.C. § 192, which can result in imprisonment of up to one
    year and a fine of up to $1,000. When a House of Congress
    holds a person in contempt, the recalcitrant subpoena recipient
    may be referred to the Department of Justice for criminal
    prosecution. McGahn asserts that by attempting to enforce its
    subpoena directly in federal court and circumventing the
    Executive’s prosecutorial role, the House infringes on the
    Executive’s exclusive authority to enforce the law. Yet the
    OLC has repeatedly opined that the criminal contempt statute
    does not and could not apply to a close Presidential advisor.
    See, e.g., Testimonial Immunity Before Congress of the Former
    Counsel to the President, 
    2019 WL 2315338
    , at *14 (O.L.C.
    May 20, 2019); Whether the Department of Justice May
    Prosecute White House Officials for Contempt of Congress, 
    32 Op. O.L.C. 65
    , 68–69 (2008) Cooper 
    Opinion, 10 Op. O.L.C. at 83
    ; Olson 
    Opinion, 8 Op. O.L.C. at 142
    ; see also Part III.B.2
    infra. So understood, the Department almost certainly would
    not pursue prosecution of McGahn. Moreover, although the
    Supreme Court in Buckley pointed to the constitutional
    principle that law enforcement is the exclusive province of the
    Executive Branch, the Court distinguished between the
    Executive Branch’s law enforcement authority and Congress’s
    “powers . . . essentially of an investigative and informative
    nature.” 
    Buckley, 424 U.S. at 137
    . The argument that the
    present lawsuit would circumvent the President’s performance
    of his constitutional law enforcement responsibilities is
    misplaced.
    29
    McGahn maintains as well that assuming jurisdiction here
    threatens to undermine the judiciary itself.              Judicial
    “intervention” in an “interbranch dispute,” he argues, could
    “risk damaging the public confidence that is vital to the
    functioning of the Judicial Branch.” Appellant Supp. Br. at 2
    (quoting 
    Raines, 521 U.S. at 833
    (Souter, J., joined by
    Ginsburg, J., concurring in the judgment)). That risk is
    minimal here not only because the Committee is a proper
    plaintiff, but also because the issue that the Committee asks the
    court to decide can be answered by applying established legal
    doctrines without the court weighing in on the political dispute
    between the House and the President. Adjudication of whether
    McGahn must appear and testify in compliance with the
    Committee’s concededly valid subpoena does not “raise[] [the]
    specter of judicial readiness to enlist on one side of a political
    tug-of-war,” 
    Raines, 521 U.S. at 834
    (Souter, J., concurring in
    the judgment). Although the present lawsuit unfolded in the
    context of a highly charged political battle over whether to
    impeach the President, the court “has a responsibility to decide
    cases properly before it, even those it ‘would gladly avoid,’”
    and “courts cannot avoid their responsibility merely ‘because
    the issues have political implications.’” 
    Zivotofsky, 566 U.S. at 194
    , 196 (first quoting Cohens v. Virginia, 19 U.S. (6 Wheat)
    264, 404 (1821), then quoting INS v. Chadha, 
    462 U.S. 919
    ,
    943 (1983)). Once the Committee has met its burden to show
    that it has Article III standing to seek judicial enforcement of
    its subpoena, the court may not avoid its responsibility to
    decide the case because of its political context or consequences.
    McGahn maintains too that courts lack the authority to
    “adjudicate disputes exclusively between the political branches
    even where no individual party’s rights are at stake.” Appellant
    Supp. Br. at 16. That objection is foreclosed by Raines and
    Arizona State Legislature. In Raines, the Court stated that “the
    30
    institutional injury [plaintiffs] allege is wholly abstract and
    widely dispersed.” 
    Raines, 521 U.S. at 829
    . By identifying
    those two defects with the alleged institutional injury, the Court
    left open the possibility that some institutional injuries would
    be sufficient to confer a legislative body standing. In other
    words, if no institutional injury to a legislative body would be
    adequate to confer standing, then the Court in Raines would not
    have bothered to identify shortcomings with the specific
    institutional injury alleged, namely, that it was “wholly abstract
    and widely dispersed.” The Court need only have stated that
    the alleged injury was an institutional one incurred by a
    legislative body and left it at that. In Arizona State Legislature
    v. Arizona Independent Redistricting Commission, 
    135 S. Ct. 2652
    , the Supreme Court held that the Arizona State
    Legislature had incurred an institutional injury where it sought
    to challenge as unconstitutional a ballot provision vesting
    redistricting authority in an independent agency. Again, the
    Court’s holding precludes the view that there is standing only
    when an individual right is implicated. See also Sixty-Seventh
    Minn. State Senate v. Beens, 
    406 U.S. 187
    (1972).
    B.
    McGahn additionally advances an interpretation of the
    Supreme Court’s decision in Raines v. Byrd, 
    521 U.S. 811
    , to
    require the conclusion that the Committee lacks Article III
    standing. He ignores Raines’s limits. The Supreme Court has
    given clear direction that Raines is a narrow case about the
    standing only of individual legislators. Nevertheless, McGahn
    relies on Raines to argue that the present dispute is not one
    “traditionally thought to be capable of resolution through the
    judicial process,” 
    Raines, 521 U.S. at 819
    . The history of
    judicial adjudication of such disputes undermines McGahn’s
    conclusion.
    31
    1.
    In Raines, six Members of Congress sued the Director of
    the U.S. Office of Management and Budget to challenge the
    constitutionality of the Line Item Veto Act, which authorized
    the President to cancel spending provisions in enacted
    appropriations statutes.
    Id. at 814–15.
    The Supreme Court
    held that the individual members of Congress lacked standing.
    Id. at 829.
    The Court has since clarified that Raines is a
    decision narrowly concerned with the standing of individual
    Members of Congress. In Arizona State Legislature, the Court
    explained that “[i]n Raines, [the] Court held that six individual
    Members of Congress lacked standing to challenge the Line
    Item Veto Act,” “holding specifically and only that ‘individual
    members of Congress [lack] Article III standing.’” Ariz. State
    
    Legislature, 135 S. Ct. at 2664
    (third alteration in original)
    (quoting 
    Raines, 521 U.S. at 813
    –14). And in Virginia House
    of Delegates v. Bethune-Hill, 
    139 S. Ct. 1945
    , the Supreme
    Court referenced Raines in deciding that a single house of a
    bicameral state legislature did not have standing to appeal
    judicial invalidation of a state redistricting plan, relying on
    Raines only for the narrow proposition that “individual
    members lack standing to assert the institutional interests of a
    legislature.”
    Id. at 1953.
    The Supreme Court has not stated that Raines would bar a
    lawsuit brought by an authorized legislative institution
    asserting an institutional injury. See 
    Raines, 521 U.S. at 829
    –
    30. Guided by Arizona State Legislature and by Raines itself,
    this court has understood Raines to concern the standing of
    individual members of a legislative body and relied on it to
    hold that unauthorized legislators lack standing to sue the
    President to vindicate injuries to the legislative bodies of which
    they are a part. See Blumenthal v. Trump, 
    949 F.3d 14
    (D.C.
    Cir. 2020); Campbell v. Clinton, 
    203 F.3d 19
    (D.C. Cir. 2000);
    32
    Chenoweth, 
    181 F.3d 112
    . All of those cases involved
    individual unauthorized legislators’ attempts to sue the
    President. In Blumenthal, the court stated that “Raines is our
    starting point when individual members of Congress seek
    judicial remedies.” 
    Blumenthal, 949 F.3d at 19
    . The court
    cited approvingly “[t]he Supreme Court’s recent summary
    reading of Raines that ‘individual members’ of the Congress
    ‘lack standing to assert the institutional interests of a
    legislature’ in the same way ‘a single House of a bicameral
    legislature lacks capacity to assert interests belonging to the
    legislature as a whole.’”
    Id. (quoting Va. House
    of 
    Delegates, 139 S. Ct. at 1953
    –54). And in Campbell the court treated
    Raines as a case about individual legislator standing, stating
    that “[t]he question whether congressmen have standing in
    federal court to challenge the lawfulness of actions of the
    executive was answered, at least in large part, in the Supreme
    Court’s recent decision in Raines v. Byrd.” 
    Campbell, 203 F.3d at 20
    .
    Arizona State Legislature and Virginia House of Delegates
    as well as this court’s precedent confirm that Raines stands for
    the proposition that whereas a legislative institution may
    properly assert an institutional injury, an individual member of
    that institution generally may not. McGahn would have this
    court disregard the clear limit that the Supreme Court itself has
    placed on Raines’s reach, something this lower court may not
    do.
    2.
    Finally, McGahn contends that the reasoning of Raines
    defeats the standing of an entire House of Congress. Taken on
    its own terms, Raines does not require the court to hold that the
    Committee lacks Article III standing. In Raines, the Supreme
    Court identified four considerations on which it relied in
    33
    holding the individual Members of Congress lacked standing:
    (1) the individual plaintiffs alleged an institutional injury that
    was “wholly abstract and widely dispersed”; (2) plaintiffs’
    “attempt to litigate th[eir] dispute at this time [wa]s contrary to
    historical experience”; (3) the plaintiffs “ha[d] not been
    authorized to represent their respective Houses of Congress . .
    . , and indeed both Houses actively oppose[d] their suit”; and
    (4) dismissing the lawsuit “neither deprive[d] Members of
    Congress of an adequate remedy . . . , nor foreclose[d] the Act
    from constitutional challenge.” 
    Raines, 521 U.S. at 829
    . The
    Court added, moreover, that “[w]hether the case would be
    different if any of these circumstances were different we need
    not now decide.”
    Id. at 829–30.
    None of the four
    considerations is present here.
    In Part 
    II supra
    , the court explained that the Committee’s
    injury is concrete and particularized and thus neither abstract
    nor widely dispersed. The Committee, unlike the unauthorized
    individual legislators in Raines, was authorized by House
    Resolution 430 to bring the present lawsuit to enforce its
    subpoena. And the OLC has twice opined that a civil
    enforcement suit is the only practicable way that a House of
    Congress may enforce a subpoena against a current or former
    Executive Branch official asserting Executive privilege,
    because neither subpoena enforcement alternative —
    prosecution by the Department for violation of the criminal
    contempt statute or detention by the House pursuant to its
    inherent contempt authority — is practicable. See Cooper
    
    Opinion, 10 Op. O.L.C. at 83
    ; Olson 
    Opinion, 8 Op. O.L.C. at 140
    , 142. The criminal contempt statute is not available to
    vindicate the House’s injury because the “contempt of
    Congress statute does not require and could not constitutionally
    require a prosecution” of an Executive Branch official who
    defies a congressional subpoena on the basis of Executive
    privilege “or even . . . a referral to a grand jury of the facts
    34
    relating to the alleged contempt.” Olson 
    Opinion, 8 Op. O.L.C. at 142
    . The alternative, detaining McGahn pursuant to the
    House’s inherent contempt authority, is similarly
    impracticable. Because Congress has not exercised its inherent
    contempt authority against an Executive Branch official since
    1917, “it seems most unlikely that Congress would dispatch the
    Sergeant-at-Arms to arrest and imprison an Executive Branch
    official who claimed executive privilege.” Cooper 
    Opinion, 10 Op. O.L.C. at 86
    . The prospect that the House will direct its
    Sergeant at Arms to arrest McGahn is vanishingly slim so long
    as a more peaceable judicial alternative remains available.
    McGahn emphasizes the historical analysis in Raines and
    concludes that because federal courts have not historically
    entertained congressional subpoena enforcement lawsuits, the
    Committee lacks standing. There are serious flaws to his
    argument, not the least of which is that the Court’s discussion
    of history in Raines informed its conclusion that individual
    legislator plaintiffs lacked standing, but did not append to the
    three-pronged standing analysis an entirely distinct historical
    prong.
    Nor does the relevant historical practice support
    McGahn’s position. For more than forty years this circuit has
    acknowledged that defiance of a subpoena issued by a House
    of Congress constitutes an institutional injury in fact that is
    judiciary remediable.      In Senate Select Committee on
    Presidential Campaign Activities v. Nixon, 
    498 F.2d 725
    , the
    en banc court declined to enforce a Senate Committee
    subpoena duces tecum served on the President for production
    of the “Nixon tapes.” In reaching the merits the court observed
    without disagreement that the district court had rejected the
    President’s contention that the lawsuit was a non-justiciable
    interbranch conflict. See
    id. at 728.
    “Finding the reasoning of
    this court in Nixon v. Sirica, which concerned a grand jury
    35
    subpoena, ‘equally applicable to the subpoena of a
    congressional committee,’ the [d]istrict [c]ourt held that, under
    that case and the relevant Supreme Court precedent, the issues
    presented to it were justiciable.”
    Id. (quoting Senate Select
    Comm. on Presidential Campaign Activities v. Nixon, 370 F.
    Supp. 521, 522 (D.D.C. 1974)). This court, satisfied with that
    analysis, proceeded to address the merits. See
    id. at 728–29.
    This court revisited a similar issue two years later in
    United States v. AT&T, 
    551 F.2d 384
    . The United States sued
    to enjoin AT&T from complying with a congressional
    Committee subpoena on national security grounds. The
    President had directed AT&T, “as an agent of the United
    States, to respectfully decline to comply with the Committee
    subpoena,”
    id. at 387,
    and the House of Representatives had
    intervened as a defendant to represent its interest in AT&T’s
    compliance with the subpoena. The court characterized the
    case as a “portentous clash between the executive and
    legislative branches,”
    id. at 385,
    and undertook a more
    extensive jurisdictional analysis than it had in Senate Select
    Committee. It concluded that “Senate Select Committee
    establishes, at a minimum, that 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.”
    Id. at 390.
    The court held that “[i]t is clear
    that the House as a whole has standing to assert its
    investigatory power.”
    Id. at 391.
    Contrary to McGahn’s position that the relative recency of
    this historical practice renders it irrelevant, historical practice
    is constitutionally significant even when it does not extend as
    far back into the past as the Founding. Interpreting the Recess
    Appointment Clause of the Constitution, the Supreme Court
    stated in NLRB v. Noel Canning, 
    573 U.S. 513
    , that “in
    interpreting the Clause, we put significant weight upon
    36
    historical practice,” and that “precedent[] show[s] that this
    Court has treated practice as an important interpretive factor
    even when the nature or longevity of that practice is subject to
    dispute, and even when that practice began after the founding
    era.”
    Id. at 5
    24–26; 
    see
    id. at 525–26
    (collecting cases).
    McGahn’s narrow view of relevant history is at odds with this
    recent pronouncement of the Supreme Court in the context of
    the constitutional separation of powers.
    In fact, the relevant history includes a long tradition of
    Presidential cooperation with the Legislative Branch
    exercising its constitutional responsibilities. Although there
    have been relatively few instances of interbranch subpoena
    enforcement litigation, the history of Presidential cooperation
    has meant that there have been few occasions necessitating
    resort to the courts. The Committee explains: “[E]arly
    Presidents overwhelmingly complied with Congressional
    inquiries, reflecting their understanding that they had a
    constitutional obligation to cooperate.” Appellee Supp. Br. at
    14; see 
    Mazars, 140 S. Ct. at 2031
    . The Presidents and the
    Houses of Congress traditionally have been able to resolve
    disputes over requests for Executive Branch documents and
    testimony. Even in pitched disputes between the branches,
    each branch traditionally has displayed respect for the
    constitutional prerogatives of the other branch and responded
    accordingly. See Appellee Supp. Br. at 14–18. The apparently
    unprecedented categorical direction by President Trump that
    no member of the Executive Branch shall cooperate with the
    Committee’s impeachment investigation, see Cipollone Letter
    of Oct. 8, 2019, to Speaker Pelosi, at 7, likely explains the
    infrequency of subpoena enforcement lawsuits such as the
    present one. See Appellee Supp. Br. at 17–18; see
    id. at 26
    .
    
    In conclusion, the present lawsuit does not “run[] afoul” of
    the “structural principle” underlying the standing inquiry,
    37
    
    Allen, 468 U.S. at 761
    , including the proper role of the judiciary
    and preservation of the status quo ante between the branches
    for over 200 years. Holding that the Committee has standing
    would safeguard the separation of powers. It would ensure the
    continuation of the “established practice” of accommodation
    by preserving the legal background against which the political
    branches have historically negotiated their informational
    disputes. It would ensure that in the rare case — here in the
    course of no less than an impeachment investigation — when
    the political branches have reached an impasse despite repeated
    attempts to resolve an informational dispute themselves, a
    congressional Committee can seek judicial enforcement of its
    duly issued subpoena. Preserving the power of a House of
    Congress to ensure compliance with its subpoena, in turn,
    enables it to carry out its constitutional responsibilities, which
    include serving as an essential check on the President and the
    Executive Branch, Federalist No. 66 (A. Hamilton); see
    Federalist No. 69 (A. Hamilton). The Supreme Court has
    placed clear limits on the scope of Raines’s holding, and taken
    on its own terms Raines is consistent with the Committee’s
    standing. In particular, the history of judicial adjudication of
    interbranch informational disputes not unlike the present one
    undermines McGahn’s position that courts have not heretofore
    resolved such disputes.
    Our dissenting colleagues reprise the views expressed in
    their panel opinions that have been vacated by the order
    granting the Committee’s petition for rehearing en banc. They
    take a different path than the en banc court in resolving the
    standing issue in the present litigation, largely adopting the
    positions that McGahn advocates. As explained at length,
    those contentions are unpersuasive. Given the rigor with which
    the en banc court has addressed the Article III standing issue
    and analyzed McGahn’s positions, there is no need to respond
    further to each our of dissenting colleagues’ opinions, other
    38
    than to underscore that the separation of powers and history are
    an integral part of, not divorced from, the en banc court’s
    standing inquiry. And because the only issue before the en
    banc court is the Committee’s Article III standing, this is not
    the occasion to respond to their views on other challenges
    raised by McGahn.
    * * * *
    Accordingly, we hold that the Committee has Article III
    standing to seek enforcement in federal court of its duly issued
    subpoena in the performance of constitutional responsibilities.
    Therefore, we affirm the judgment of the district court in part.
    Consideration of McGahn’s other contentions — including
    threshold pre-merits objections that there is no subject matter
    jurisdiction and no applicable cause of action, and potential
    consideration of the merits if reached — remain to be decided
    and are remanded to the panel to address in the first instance.
    KAREN LECRAFT HENDERSON, Circuit Judge, dissenting:
    The Court holds today that the Committee on the Judiciary of
    the United States House of Representatives (Committee) has
    Article III standing to bring suit in federal court to enforce
    subpoenas against the Executive Branch. I dissent for the
    reasons stated in my concurrence in Committee on the
    Judiciary of the United States House of Representatives v.
    McGahn, 
    951 F.3d 510
    , 531–42 (D.C. Cir. 2020), vacated,

    v. Mnuchin, No. 19-5176, 
    2020 WL 1228477
    (D.C. Cir. Mar.
    13, 2020), and I incorporate by reference thereto that
    previously published opinion as my dissent here. I write
    separately, however, to address recent Supreme Court case law
    whose effect the majority has minimized.
    “Standing to sue is a doctrine rooted in the traditional
    understanding of a case or controversy,” Spokeo, Inc. v. Robins,
    
    136 S. Ct. 1540
    , 1547 (2016), which, “[i]n the constitutional
    sense, . . . means the kind of controversy courts traditionally
    resolve,” United States v. Nixon, 
    418 U.S. 683
    , 696 (1974).
    Derived “[f]rom Article III’s limitation of the judicial power
    . . . and the separation-of-powers principles underlying that
    limitation,” Lexmark Int’l, Inc. v. Static Control Components,
    Inc., 
    572 U.S. 118
    , 125 (2014), our standing inquiry therefore
    “serves to identify those disputes which are appropriately
    resolved through the judicial process,” Whitmore v. Arkansas,
    
    495 U.S. 149
    , 155 (1990). This suit is not one of them.
    For over two hundred years, the coordinate branches did
    not enlist the Judiciary in their fights. But our court did not
    leave well enough alone and, roughly forty years ago, set about
    to “umpire disputes between th[e] branches regarding their
    respective powers.” Moore v. U.S. House of Representatives,
    
    733 F.2d 946
    , 959 (D.C. Cir. 1984) (Scalia, J., concurring in
    the judgment). This approach started to collapse under its own
    weight, however, as “the Supreme Court began to place greater
    emphasis upon the separation of powers concerns underlying

    the Article III standing requirement,” Chenoweth v. Clinton,
    
    181 F.3d 112
    , 114 (D.C. Cir. 1999), and after Raines v. Byrd,
    
    521 U.S. 811
    (1997), our “broad theory of legislative standing”
    became untenable, see 
    Chenoweth, 181 F.3d at 117
    n.*.
    Notwithstanding our court’s past ill-advised effort to mediate
    battles between the political branches, the fact remains that the
    High Court has yet to sanction such an intrusion and we, an
    inferior court, should not take it upon ourselves to alter the
    balance of powers. The majority “opinion is like a pirate ship.
    It sails under a [separation-of-powers] flag,” Bostock v.
    Clayton Cnty., 
    140 S. Ct. 1731
    , 1755 (2020) (Alito, J., joined
    by Thomas, J., dissenting); see, e.g., Majority Op. at 36–37, but
    in fact undermines the calibrated system of interbranch conflict
    resolution the Constitution requires.
    Granted, “merely invoking separation of powers
    principles,” Majority Op. at 20, does not automatically
    preclude us from exercising the judicial power. Indeed, this
    case implicates the separation of powers in multiple ways, not
    all of which affect the Committee’s standing. The “separation
    of powers concerns” that arise in an “interbranch conflict” over
    “[c]ongressional demands for the President’s information,”
    Trump v. Mazars USA, LLP, 
    140 S. Ct. 2019
    , 2035 (2020), do
    not necessarily place a suit beyond our ken, see NLRB v. Noel
    Canning, 
    573 U.S. 513
    , 525 (2014) (“[I]t is the ‘duty of the
    judicial department’—in a separation-of-powers case as in any
    other—‘to say what the law is.’” (quoting Marbury v. Madison,
    5 U.S. (1 Cranch) 137, 177 (1803)). But there is also the “time-
    honored concern about keeping the Judiciary’s power within
    its proper constitutional sphere,” 
    Raines, 521 U.S. at 820
    , and
    this separation-of-powers element, indivisible from Article III
    standing, “confines the federal courts to a properly judicial
    role,” 
    Spokeo, 136 S. Ct. at 1547
    .
    3
    Although the majority appears to recognize as much, see,
    e.g., Majority Op. at 19–20, it gives short shrift to the fact that
    an injury must therefore be “personal, particularized, concrete,
    and otherwise judicially cognizable,” 
    Raines, 521 U.S. at 820
    (emphasis added), “to ensure that federal courts do not exceed
    their authority as it has been traditionally understood,” 
    Spokeo, 136 S. Ct. at 1547
    . Legislative bodies are not exempt from the
    requirement that “an injury must be ‘legally and judicially
    cognizable,’” Va. House of Delegates v. Bethune-Hill, 
    139 S. Ct. 1945
    , 1953 (2019) (quoting 
    Raines, 521 U.S. at 819
    ), and
    Article III standing may be wanting if, after “consult[ing]
    history and judicial tradition,” Ariz. State Legislature v. Ariz.
    Indep. Redistricting Comm’n, 
    135 S. Ct. 2652
    , 2695 (2015)
    (Scalia, J., joined by Thomas, J., dissenting), the dispute is not
    “of the sort traditionally amenable to, and resolved by, the
    judicial process,” Steel Co. v. Citizens for a Better Env’t, 
    523 U.S. 83
    , 102 (1998). Simply put, we must consider whether the
    Committee’s “attempt to invoke the power of a federal court
    . . . is consistent with the structure created by the Federal
    Constitution” and “[a]n interest . . . that is inconsistent with that
    structure may not be judicially cognizable.” 
    Bethune-Hill, 139 S. Ct. at 1959
    (Alito, J., joined by Roberts, C.J., Breyer, J., and
    Kavanaugh, J., dissenting).
    I continue to believe the longstanding practice of resolving
    political disputes without judicial intervention counsels against
    the Committee’s standing here. “[T]he Constitution established
    that ‘[j]udicial power could come into play only in matters that
    were the traditional concern of the courts at Westminster,’” Vt.
    Agency of Nat. Res. v. United States ex rel. Stevens, 
    529 U.S. 765
    , 774 (2000) (second alteration in original) (quoting
    Coleman v. Miller, 
    307 U.S. 433
    , 460 (1939) (Frankfurter, J.,
    dissenting)), and “[c]ertainly neither the houses of Parliament
    nor the British monarchs ever considered submitting their
    disputes to the courts,” JOSH CHAFETZ, CONGRESS’S
    4
    CONSTITUTION 190 (2017). Likewise, “in analogous
    confrontations between one or both Houses of Congress and
    the Executive Branch, no suit was brought on the basis of
    claimed injury to official authority or power,” 
    Raines, 521 U.S. at 826
    , despite the fact that these “decades-long disputes . . .
    would surely have been promptly resolved by a Congress-vs.-
    the-President lawsuit if the impairment of a branch’s powers
    alone conferred standing to commence litigation. But it does
    not, and never has . . . .” United States v. Windsor, 
    570 U.S. 744
    , 790 (2013) (Scalia, J., joined by Roberts, C.J., and
    Thomas, J., dissenting).1
    Just last month, the Supreme Court emphasized that
    interbranch disputes like this one “have not ended up in court.
    Instead, they have been hashed out in the ‘hurly-burly, the give-
    and-take of the political process between the legislative and the
    executive.’” 
    Mazars, 140 S. Ct. at 2029
    (quoting Executive
    Privilege—Secrecy in Government: Hearings on S. 2170, S.
    2378 and S. 2420 Before the Subcomm. on Intergovernmental
    Rels. of the S. Comm. on Gov’t Operations, 94th Cong. 87
    (1975) (statement of Antonin Scalia, Assistant Att’y Gen.,
    Office of Legal Counsel)). Under the guise of “preserv[ing] . . .
    that historical practice of accommodation,” Majority Op. at 23,
    the majority posits that without the possibility “of a subpoena
    enforcement lawsuit”—i.e., a judicial remedy—“the Executive
    Branch faces little incentive to reach a negotiated agreement in
    an informational dispute” with the Congress
    , id. at 24.
    But
    1
    The majority is quick to cabin Raines to its facts. But even
    accepting, arguendo, the majority’s premise “that Raines is a narrow
    case about the standing only of individual legislators,” Majority Op.
    at 30, it does not follow that Raines’s discussion of historical practice
    is therefore stripped of persuasive effect, cf. 
    Windsor, 570 U.S. at 790
    (Scalia, J., joined by Roberts, C.J., and Thomas, J., dissenting)
    (“Raines d[oes] not formally decide this issue, but its reasoning
    does.”).
    5
    “[f]or more than two centuries, the political branches have
    resolved information disputes” themselves. 
    Mazars, 140 S. Ct. at 2035
    .
    In suggesting that the Judiciary is needed to “keep[] the
    Executive Branch at the negotiating table,” Majority Op. at 24,
    the majority largely ignores “the wide variety of means that the
    Constitution puts at [the House’s] disposal,” 
    Mazars, 140 S. Ct. at 2035
    , if a recalcitrant President orders “widescale non-
    compliance with lawful inquiries by a House of Congress,”
    Majority Op. at 25. The House may, for example, withhold
    appropriations or, as it did here, impeach the President for
    “[d]irecting the . . . def[iance of] a lawful subpoena.” H.R. Res.
    755, 116th Cong., at 6 (2019).2 Thus, even if the House is
    unlikely to invoke its inherent contempt authority or pursue a
    criminal prosecution, see Majority Op. at 33–34, it is untrue
    that “no practicable alternative to litigation exists,”
    id. at 26
    .
    
    The political process may be messy, subject to the pitfalls of
    supercharged partisanship, but “we must put aside the natural
    urge . . . to ‘settle’ [this dispute] for the sake of convenience
    and efficiency,” 
    Raines, 521 U.S. at 820
    , no matter how
    tantalizing a “judicial alternative” appears, Majority Op. at 34.
    2
    Although the Constitution expressly provides these
    mechanisms to resolve interbranch conflict, it is notably silent on the
    Judiciary’s role in such disputes. Considering Article III carved out
    “as specific, independent categories of federal judicial power,
    ‘controversies’ between states, between a state and citizens of
    another state, and so on[,] . . . it is incredible that Framers who
    intended to extend judicial power to direct controversies between
    Congress and the President failed to include so important a category
    in their recitation.” Barnes v. Kline, 
    759 F.2d 21
    , 57 (D.C. Cir. 1984)
    (Bork, J., dissenting), vacated sub nom. Burke v. Barnes, 
    479 U.S. 361
    (1987).
    6
    By holding that the Committee has standing, the majority
    enlarges the Judiciary’s power to intervene in battles that
    should be waged between the Legislature and the Executive
    and opens the door to future disputes between the political
    branches. Cf. Warth v. Seldin, 
    422 U.S. 490
    , 498 (1975)
    (“[Standing] is founded in concern about the proper—and
    properly limited—role of the courts in a democratic society.”).
    Even if “the precise function” we perform in this case—
    subpoena enforcement—“is a traditional feature of civil
    litigation in federal court,” Majority Op. at 27, “congressional
    subpoenas directed at” the Executive Branch “differ markedly”
    because they “unavoidably pit the political branches against
    one another,” 
    Mazars, 140 S. Ct. at 2034
    . This distinction
    matters. If the interbranch character of the dispute was of no
    consequence, any President could presumably challenge in
    court laws that he believes infringe upon Article II powers. And
    statutory interpretation, like subpoena enforcement, is also a
    “familiar judicial exercise.” Majority Op. at 26 (quoting
    Zivotofsky ex rel. Zivotofsky v. Clinton, 
    566 U.S. 189
    , 196
    (2012)). Although “[t]here would be nothing irrational about a
    system that granted standing in” such a case, “it is obviously
    not the regime that has obtained under our Constitution to
    date.” 
    Raines, 521 U.S. at 828
    . “In limiting the judicial power
    to ‘Cases’ and ‘Controversies,’ Article III of the Constitution
    restricts it to the traditional role of Anglo-American courts,”
    Summers v. Earth Island Inst., 
    555 U.S. 488
    , 492 (2009), which
    did not hear suits between coordinate branches of government.
    The majority’s broad conception of legislative standing,
    however, disregards this limitation. Accordingly, I respectfully
    dissent.
    GRIFFITH, Circuit Judge, dissenting: Today the court
    relegates the separation of powers from a core component of
    Article III to an afterthought. The court severs the standing
    analysis from its separation-of-powers roots and treats a direct
    dispute between the Legislative and Executive Branches as if
    it were any old case. The result is an anemic Article III
    jurisprudence that flouts a long line of Supreme Court
    precedent, ignores the basic structure of the Constitution, and
    resuscitates long-discredited case law from this circuit.
    And for what? Who benefits from today’s decision? Not
    Congress. The majority’s ruling will supplant negotiation with
    litigation, making it harder for Congress to secure the
    information it needs. And the Committee likely won’t even get
    what it wants in this case. Because the majority declines to
    decide whether the Committee has a cause of action and
    whether it should prevail on the merits, the chances that the
    Committee hears McGahn’s testimony anytime soon are
    vanishingly slim. The federal courts won’t benefit, either. The
    majority’s decision will compel us to referee an interminable
    series of interbranch disputes, politicizing the Judiciary by
    repeatedly forcing us to take sides between the branches. Most
    importantly, the decision does grave harm to the Constitution’s
    system of separated powers, which constrains federal courts to
    the narrow task of resolving concrete “Cases” and
    “Controversies” so that elected representatives call the political
    shots. I cannot join the court’s expedition into an area where
    we do not belong and can do no good.
    I
    The most puzzling aspect of today’s decision is the court’s
    disregard for the relationship between Article III and the
    separation of powers. Heedless of the interbranch nature of this
    dispute, the majority trots through the three-part standing test
    from Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    (1992), as if
    the Committee were just like a private party enforcing a
    2
    subpoena in a breach-of-contract suit. The majority returns this
    circuit to the prudential approach to standing that we
    experimented with decades ago and that the Supreme Court
    rejected in Raines v. Byrd, 
    521 U.S. 811
    (1997). And the court
    fails to offer any limits to its revived doctrine of congressional
    standing, leaving future panels to struggle to find a coherent
    stopping point.
    A
    The majority’s disregard for the separation of powers is
    apparent on the face of the opinion. The court announces its
    “skepticism” that “the separation of powers . . . bear[s] on
    whether the Committee has Article III standing.” Maj. Op. at
    20. The Supreme Court might be surprised to hear that. Time
    and again, the Court has said that standing “is built on a single
    basic idea—the idea of separation of powers.” 
    Raines, 521 U.S. at 820
    (internal quotation marks omitted). For that reason,
    “questions . . . relevant to the standing inquiry must be
    answered by reference to the Art[icle] III notion that federal
    courts may exercise power . . . only when adjudication is
    consistent with a system of separated powers.” Allen v. Wright,
    
    468 U.S. 737
    , 752 (1984); see also
    id. at 761
    n.26; Susan B.
    Anthony List v. Driehaus, 
    573 U.S. 149
    , 157 (2014); Steel Co.
    v. Citizens for a Better Env’t, 
    523 U.S. 83
    , 102 (1998); Flast v.
    Cohen, 
    392 U.S. 83
    , 97 (1968).
    The “concrete injury” requirement imbues standing
    doctrine with its “separation-of-powers significance.” 
    Lujan, 504 U.S. at 577
    . That requirement is also “grounded in
    historical practice,” and we must ask whether an alleged harm
    “has traditionally been regarded as providing a basis for a
    lawsuit in English or American courts.” Spokeo, Inc. v. Robins,
    
    136 S. Ct. 1540
    , 1549 (2016). The Judiciary does not and never
    has resolved direct disputes between the political branches. The
    3
    “traditional role” of the federal courts “is to redress or prevent
    actual or imminently threatened injury to persons caused by
    private or official violation of law.” Summers v. Earth Island
    Inst., 
    555 U.S. 488
    , 492 (2009). Interbranch disputes thus “lie[]
    far from the . . . conceptual core of the case-or-controversy
    requirement.” 
    Raines, 521 U.S. at 833
    (Souter, J., concurring
    in the judgment); see also Ariz. State Legislature v. Ariz. Indep.
    Redistricting Comm’n, 
    135 S. Ct. 2652
    , 2665 n.12 (2015)
    (noting that lawsuits between the Legislative and Executive
    Branches raise “separation-of-powers concerns”).
    Those considerations about the traditional role of the
    Judiciary bear directly on whether the Committee’s asserted
    injury—deprivation of testimony that hinders the Committee in
    “carrying out its constitutional functions,” Maj. Op. at 14—
    suffices to establish standing. We thus cannot evaluate whether
    this suit presents an Article III case or controversy by
    abstracting away from the critical facts: the Committee on the
    Judiciary of the United States House of Representatives is
    suing the former White House Counsel to compel him to
    divulge information obtained during the course of his duties,
    and the Committee seeks that information to effectuate its
    institutional prerogatives to conduct oversight of the Executive
    Branch and to impeach the President. The question is whether
    that injury to the Committee is “legally and judicially
    cognizable,” and whether that claim is “traditionally thought to
    be capable of resolution through the judicial process.” 
    Raines, 521 U.S. at 819
    (internal quotation marks omitted).
    Yet the majority breezes through the injury-in-fact
    analysis with scarcely a word about the interbranch nature of
    this dispute. See Maj. Op. at 7-18. Because “private parties
    undeniably have standing to seek judicial enforcement of
    compliance with subpoenas,” the majority reasons, the
    Committee must also have standing to enforce the Executive
    4
    Branch’s compliance with a congressional subpoena.
    Id. at 14.
    But that analogy breaks down twice over. First, the fact that we
    may resolve similar information disputes between private
    parties does not answer whether we can resolve an interbranch
    information dispute. Second, although enforcement of a
    subpoena issued under the auspices of our own Article III
    power is a “familiar judicial exercise,”
    id. at 26
    (quotation
    marks omitted), there is nothing “[]usual” or “traditional,”
    id., about the Committee’s
    request that Article III judges enforce
    an Article I subpoena against an Article II officer.
    The majority’s entire affirmative case is thus premised on
    a faulty analogy between an injury to private parties and an
    injury to Congress. The majority justifies its neglect of the
    interbranch nature of this dispute by arguing that separation-of-
    powers concerns require its standing analysis to be “‘especially
    rigorous,’” not that those “separation of powers concern[s] . . .
    must be part of [its] standing analysis.”
    Id. at 21
    (quoting
    
    Raines, 521 U.S. at 819
    -20). I confess I do not know what it
    means to conduct the “rigorous” standing analysis that the
    separation of powers requires without considering the
    separation of powers as part of that analysis. The majority
    makes no substantive mention of the separation of powers until
    eighteen pages into the opinion, and even then, it asks only
    whether “separation of powers principles defeat[]” the outcome
    of its standing analysis.
    Id. at 20.
    The court cannot cure its
    initial error with a belated and half-hearted discussion of the
    separation-of-powers considerations that should have informed
    its injury-in-fact analysis.
    B
    The Supreme Court has already rejected the majority’s
    two-step approach, in which it considers standing first and the
    separation of powers later. In a string of decisions beginning in
    5
    1974, we held—“[o]ver strong dissent”—“that Members of
    Congress may have standing when” “they assert injury to their
    institutional power as legislators.” 
    Raines, 521 U.S. at 820
    n.4.
    Recognizing that separation-of-powers considerations did bear
    on the justiciability of these suits, however, we developed a
    doctrine of “circumscribed equitable discretion” so we could
    dismiss some cases as nonjusticiable even if we found
    legislative standing. Chenoweth v. Clinton, 
    181 F.3d 112
    , 114
    (D.C. Cir. 1999). “Keeping distinct our analysis of standing
    and our consideration of the separation of powers,” we
    reasoned, allowed us to treat “congressional and private
    plaintiffs . . . alike for the purpose of determining their
    standing.”
    Id. The Supreme Court
    rejected that practice in Raines, and
    we set ourselves straight, until today. After Raines, we
    recognized that the Supreme Court was “unmoved by [our]
    concern” that “consideration of separation of powers issues
    would distort our standing analysis.”
    Id. at 115
    (internal
    quotation marks omitted). We then concluded that Raines
    “require[d] us to merge our separation of powers and standing
    analyses.”
    Id. at 116.
    In other words, we rejected the circuit’s
    bifurcated approach that asked (1) whether “[congressional]
    plaintiffs [would have] had standing to sue” if they were a
    private party, and then (2) whether the “separation of powers
    problems [the lawsuit] created” demanded that we dismiss the
    suit anyway.
    Id. at 115
    .
    Despite that course correction, the court again today treats
    the separation of powers as a backstop on our jurisdiction—an
    atmospheric concern to be considered only after we decide that
    a congressional plaintiff has standing. See Maj. Op. at 18-37.
    The majority dutifully recites Chenoweth’s command to
    integrate separation-of-powers concerns into the standing
    analysis, but then goes on to reject the proposition that the
    6
    separation of powers is a “necessary part of [the] standing
    analysis.” Maj. Op. at 21. The majority treats the Executive
    Branch’s separation-of-powers concerns as free-floating
    objections, asking whether they negate the outcome of a
    standing analysis conducted oblivious to these concerns. But
    that approach is backwards, and it replicates this circuit’s
    discredited pre-Raines effort to consider congressional
    standing in isolation from the separation of powers.
    If the Court’s first rebuke in Raines failed to convince us
    to take separation-of-powers concerns seriously, the second
    should have. Just a few short weeks ago, the Supreme Court
    vacated and remanded our decision in a different congressional
    subpoena case for failing to “take[] adequate account of the
    separation of powers principles at stake.” Trump v. Mazars
    USA, LLP, No. 19-715, slip op. at 18, 20 (U.S. July 9, 2020).
    Still, the court once again expresses “skepticism” that
    separation-of-powers principles should guide its analysis. Maj.
    Op. at 20.
    C
    1
    The majority’s return to the D.C. Circuit’s old way—a
    check-the-box approach to standing coupled with desultory
    review of the lawsuit’s separation-of-powers implications—
    places effectively no limitations on Congress’s ability to haul
    the Executive Branch into court. The majority concludes that
    the Committee suffered a “concrete” injury because McGahn
    “denied the Committee something to which it alleges it is
    entitled by law,”
    id. at 13,
    but that reasoning is boundless. Any
    claim that Congress might bring against the Executive Branch
    alleges a deprivation of something to which Congress is
    entitled by law.
    7
    Consider just a few possibilities. Under the majority’s
    reasoning, why couldn’t Congress (or the House or the Senate
    or a committee) challenge any Executive Order that allegedly
    violated the Bicameralism and Presentment Clause? See
    
    Chenoweth, 181 F.3d at 113
    . Or any military action that
    allegedly violated the Declare War Clause? See Campbell v.
    Clinton, 
    203 F.3d 19
    , 19 (D.C. Cir. 2000). Or one of the
    Executive Branch’s spending decisions that allegedly violated
    the Appropriations Clause? See U.S. House of Representatives
    v. Mnuchin, No. 19-5176 (D.C. Cir. Aug. 7, 2020) (Griffith, J.,
    dissenting). Just as in this case, each hypothetical suit involves
    allegations that Congress has been denied something to which
    it is entitled by law—the prerogative to enact statutes, or to
    declare war, or to appropriate funds. The majority’s stripped-
    down conception of standing authorizes Congress to bring all
    these suits and more.
    Worse, if Congress or one of its chambers may sue the
    Executive Branch, “it must follow that the President may, by
    the same token, sue Congress.” Barnes v. Kline, 
    759 F.2d 21
    ,
    46 (D.C. Cir. 1984) (Bork, J., dissenting), vacated sub
    nom. Burke v. Barnes, 
    479 U.S. 361
    (1987). Under the
    majority’s reasoning, whenever Congress passes a statute that
    the President believes invades his constitutional prerogatives,
    he could come into court to obtain a judicial declaration on that
    statute’s constitutionality. And why stop at suits between the
    Legislative and Executive Branches? The D.C. Circuit could
    sue Congress for stripping its habeas jurisdiction over
    Guantanamo Bay by alleging that Congress deprived it of its
    jurisdiction. Cf.
    id. Once the courthouse
    doors are open, there’s no reason to
    expect the branches to be judicious about the suits they bring.
    Even the General Counsel for the House conceded that
    8
    allowing such interbranch suits poses a serious “floodgates
    problem.” Oral Arg. Tr. 100:13; see also
    id. at 103:23.
    Given
    the majority’s conclusion that a deprivation of a legal right
    satisfies Article III, I see no reason to exclude any of these
    cases from our jurisdiction. After all, each involves an
    institutional plaintiff alleging a deprivation of a constitutional
    prerogative. And because our standing analysis requires us to
    assume the plaintiff’s success on the merits, we would have to
    entertain any claim alleging such a deprivation, no matter how
    outlandish. In short order, we could be forced to interpret
    constitutional provisions that have traditionally been
    interpreted by the political branches and “never before . . . by
    the federal courts,” Schlesinger v. Reservists Comm. to Stop the
    War, 
    418 U.S. 208
    , 221 (1974), and that courts should consider
    only “in the last resort, and as a necessity,” 
    Raines, 521 U.S. at 819
    (internal quotation marks omitted).
    That cannot be right. If “the concrete injury requirement
    has the separation-of-powers significance” that the Supreme
    Court has “always said” it has, 
    Lujan, 504 U.S. at 577
    , then the
    answer to whether these injuries suffice for Article III standing
    must be a resounding “No.” Components of the government
    cannot bring suit alleging that another branch has caused the
    “abstract dilution of institutional . . . power.” 
    Raines, 521 U.S. at 826
    . When a branch “asserts a ‘right’ that consists of the
    exercise of (or participation in the exercise of) a political
    power, the business of the political branches is the very object
    of the dispute, no matter with what degree of particularity the
    ‘right’ has been conferred.” Moore v. U.S. House of
    Representatives, 
    733 F.2d 946
    , 958 (D.C. Cir. 1984) (Scalia, J.,
    concurring in the judgment). If the political branches were
    deemed to have a judicially cognizable interest in the “powers
    that have been conferred upon them (whether specifically or
    vaguely) by Constitution or statute,” our system of separated
    9
    powers would be reduced to a system of “judicial refereeship.”
    Id. at 959.
    The majority hints (but never says) that the denial of
    Congress’s right to information is somehow more concrete than
    other deprivations of institutional rights. But as the majority
    opinion emphasizes, the reason that McGahn’s refusal to testify
    harms the House is that it subverts the House’s ability “to
    legislate, to conduct oversight,” and “to impeach and remove a
    President.” Maj. Op. at 3. Those injuries are allegations that the
    House’s institutional prerogatives have been frustrated by the
    Executive Branch’s assertion of absolute testimonial
    immunity. And those injuries are no more concrete than any
    other assertion that the Executive Branch has taken power from
    Congress, or that Congress has taken power from the President.
    Thus, although the majority evaluates only the
    Committee’s asserted informational harm, its reasoning
    sweeps far more broadly. And neither the court nor the
    Committee has offered any principled limitations on that
    sweep. Indeed, by refusing to resolve the companion case in
    Mnuchin, the full court passes on the chance to offer guidance
    about the outer limits of its reasoning. See Mnuchin, No. 19-
    5176, slip op. at 3-4 (Griffith, J., dissenting). Today’s decision
    will leave future panels to assess these suits on a case-by-case
    basis, deciding whether the constitutional power that has
    allegedly been diluted strikes them as specific enough (or
    important enough) to intervene. All the while, the branches’
    ability to settle matters on their own will grind to a halt as they
    submit themselves to the D.C. Circuit’s superintendence.
    2
    Even assuming that informational injuries are uniquely
    “concrete” and the majority’s decision can be cabined to just
    10
    these disputes, the opinion still opens the courthouse doors to
    unending litigation. The court deems the dispute in today’s
    litigation “discrete and limited,” Maj. Op. at 27, but the
    Committee admitted before the panel that—if McGahn
    testified and the Committee disagreed with his assertions of
    executive privilege—it would seek further relief, perhaps
    through emergency motions, to compel him to talk. See Comm.
    on the Judiciary v. McGahn, 
    951 F.3d 510
    , 518 (D.C. Cir.
    2020) (McGahn I), reh’g en banc granted sub nom. U.S. House
    of Representatives v. Mnuchin, No. 19-5176, 
    2020 WL 1228477
    (D.C. Cir. Mar. 13, 2020). Today’s decision invites
    that litigation, establishing the D.C. Circuit as the continuous
    monitor of congressional oversight hearings.
    Supervising these hearings and other information disputes
    will be an unhappy task for judges who value the public
    perception of impartiality. Because “congressional subpoenas
    for [executive-branch] information unavoidably pit the
    political branches against one another,” Mazars, slip op. at 15,
    entertaining these suits will invariably put us in the “awkward
    position” of choosing a winner in repeated contests of power
    and privilege, Cheney v. U.S. Dist. Court for D.C., 
    542 U.S. 367
    , 389 (2004). We will be forced to balance “the Executive’s
    claims of confidentiality and autonomy” against Congress’s
    asserted need for information.
    Id. And we will
    have to make
    such decisions about records and testimony “of intense political
    interest for all involved.” Mazars, slip op. at 17. Resolving
    these disputes will not just threaten the neutrality of the
    Judiciary; it will require the branches to submit to our views of
    their constitutional prerogatives on our timeline. Nobody wins
    when we place “the Constitution’s entirely anticipated political
    arm wrestling into permanent judicial receivership.” United
    States v. Windsor, 
    570 U.S. 744
    , 791 (2013) (Scalia, J.,
    dissenting).
    11
    II
    Unlike the majority, I would integrate the separation-of-
    powers considerations into the standing analysis. As I have
    already explained, this dispute is neither “consistent with a
    system of separated powers” nor “traditionally thought to be
    capable of resolution through the judicial process.” McGahn 
    I, 951 F.3d at 516
    (quoting 
    Allen, 468 U.S. at 752
    ). Accordingly,
    as discussed at length in the panel opinion, it must be
    dismissed.
    Once again, the Judiciary cannot resolve pure interbranch
    disputes. Federal courts primarily sit “to decide on the rights of
    individuals,” Marbury v. Madison, 5 U.S. (1 Cranch) 137, 170
    (1803), and our core function is “to redress or prevent actual or
    imminently threatened injury to persons caused by private or
    official violation of law,” 
    Summers, 555 U.S. at 492
    . To be
    sure, that task sometimes requires us to resolve deeply
    controversial political disputes. But we resolve those disputes
    “only in the last resort, and as a necessity in the determination
    of [a] real, earnest, and vital controversy between individuals.”
    Chicago & G.T. Ry. v. Wellman, 
    143 U.S. 339
    , 345 (1892).
    Because we address such disputes only “in the course of
    carrying out the judicial function” of resolving cases or
    controversies, DaimlerChrysler Corp. v. Cuno, 
    547 U.S. 332
    ,
    340 (2006), we cannot intervene in an interbranch dispute
    unless and until the actions of one of the branches harms an
    entity “beyond the [Federal] Government,” 
    Raines, 521 U.S. at 834
    (Souter, J., concurring in the judgment).
    It is no accident that every major separation-of-powers
    case to reach the Supreme Court in the Nation’s history fits
    exactly that pattern. In Marbury v. Madison, William Marbury
    sought his “commission as a justice of the 
    peace.” 5 U.S. at 154
    . Humphrey’s Executor arose because William Humphrey’s
    12
    estate sought to collect backpay after President Roosevelt fired
    Humphrey. 
    295 U.S. 602
    , 618-19 (1935). In INS v. Chadha,
    Jagdish Rai Chadha—a man admitted to the United States on a
    student visa—sought to remain in the country. 
    462 U.S. 919
    ,
    923 (1983). United States v. Nixon arose out of a judicial
    subpoena issued in the “regular course of [the] federal criminal
    prosecution” of seven Watergate burglars. 
    418 U.S. 683
    , 687,
    697 (1974). And both Free Enterprise Fund and Seila Law
    involved private companies subject to government
    investigations. Seila Law LLC v. CFPB, No. 19-7, slip op. at 6
    (U.S. June 29, 2020); Free Enter. Fund v. Pub. Co. Accounting
    Oversight Bd., 
    561 U.S. 477
    , 487 (2010); see also McGahn 
    I, 951 F.3d at 520-21
    (listing other separation-of-powers cases
    that all involved the “concrete interests of private actors”).
    Neither the Committee nor the court identifies a single
    example of a direct interbranch dispute—on any issue—
    resolved by the Supreme Court. Ever. The Supreme Court’s
    explanation in Raines remains true today: History is replete
    with “confrontations between one or both Houses of Congress
    and the Executive Branch,” but until recently, “no suit was
    brought on the basis of claimed injury to official authority or
    power.” 
    Raines, 521 U.S. at 826
    . If a chamber of Congress
    could sue the Executive Branch to enforce its institutional
    prerogatives—be it the right to participate in appointments, or
    the right to vote to go to war—the U.S. Reports should be
    littered with these claims. They are not.
    The same is true of the subset of interbranch disputes at
    issue here: conflicts about information. Since the Founding,
    “congressional demands for [executive-branch] information
    have been resolved by the political branches without involving
    [the] [c]ourt[s].” Mazars, slip op. at 9. The only remotely
    similar dispute that the Supreme Court has ever addressed
    involved the rights of private parties; Mazars was brought by
    13
    “the President in his personal capacity” and “his children and
    affiliated businesses” against a third-party accounting firm.
    Id. at 5
    (emphasis added). Altogether, the “complete novelty of the
    direct intermediation of the courts in disputes between the
    President and the Congress[] ought to give us pause.” 
    Barnes, 759 F.2d at 41
    (Bork, J., dissenting).
    But as with the separation of powers, the majority
    dismisses this history as extraneous to the standing analysis,
    suggesting that the Supreme Court has never “append[ed]” a
    “historical prong” to the three-part standing test elucidated in
    Lujan. Maj. Op. at 34. No, there is no fourth prong, but in
    determining whether a “harm constitutes [an] injury in fact,”
    “history . . . play[s an] important role[].” 
    Spokeo, 136 S. Ct. at 1549
    . The Supreme Court has repeatedly emphasized that
    Article III limits us to adjudicating claims “traditionally
    thought to be capable of resolution through the judicial
    process.” 
    Allen, 468 U.S. at 752
    (internal quotation marks
    omitted); see also 
    Lujan, 504 U.S. at 559-60
    (explaining that
    our jurisdiction “depends largely upon common understanding
    of what activities are appropriate to legislatures, to executives,
    and to courts”); Rucho v. Common Cause, 
    139 S. Ct. 2484
    ,
    2494 (2019); 
    Raines, 521 U.S. at 818
    -20; Flast v. Cohen, 
    392 U.S. 83
    , 97 (1968). How else could we identify the
    “traditional” limits on our jurisdiction without consulting that
    history?
    And the best history that the majority can muster is four
    decisions all within the last forty-five years—two in this
    circuit, two in the district court. See Maj. Op. at 23-24. But
    “[t]hese few scattered examples . . . shed little light” on the
    constitutionality of judicial resolution of interbranch disputes.
    Seila Law, slip op. at 19 (internal quotation marks omitted).
    The majority professes itself untroubled by the rarity and
    recency of these historical examples, speculating that perhaps
    14
    a “long tradition of Presidential cooperation” minimized the
    need for such suits in the past. Maj. Op. at 36. But Presidents
    of all stripes—including Washington, Adams, Jefferson,
    Monroe, Lincoln, Theodore Roosevelt, Franklin Roosevelt,
    Truman, Carter, Reagan, Bush, and Obama—withheld
    information from Congress during their presidencies. See
    Comm. on Oversight & Gov’t Reform v. Holder, 
    979 F. Supp. 2d
    1, 5-7 (D.D.C. 2013); Comm. on the Judiciary v. Miers, 
    558 F. Supp. 2d 53
    , 57-64 (D.D.C. 2008); History of Refusals by
    Executive Branch Officials to Provide Information Demanded
    by Congress, 
    6 Op. O.L.C. 751
    , 751-81 (1982).
    It is the majority’s view that is the outlier. For years, the
    political branches agreed to resolve their interbranch
    information disputes with negotiation rather than litigation.
    Even setting aside the nearly unbroken history of political
    resolution of interbranch information disputes leading up to our
    adventurous decisions in the 1970s, the political branches have
    each recently opposed the majority’s conclusion. For instance,
    the Bush and Obama Administrations both resisted judicial
    resolution of these disputes. See Mem. in Supp. of Def.’s Mot.
    to Dismiss at 30, Comm. on Oversight & Reform v. Holder, No.
    12-cv-1332 (D.D.C. Oct. 15, 2012), Dkt. No. 13-1 (President
    Obama); Mem. in Supp. of Def.’s Mot. to Dismiss at 24,
    Comm. on the Judiciary v. Miers, No. 08-cv-0409 (D.D.C. May
    9, 2008), Dkt. No. 16-1 (President Bush).
    And despite the Committee’s current litigating position,
    Congress has also long agreed that these disputes are not fit for
    judicial resolution. During the Watergate impeachment
    investigation of President Nixon, for instance, the Committee
    on the Judiciary concluded that it “would be inappropriate to
    seek the aid of the courts to enforce its subpoenas against the
    President.” H.R. REP. NO. 93-1305, at 210 (1974). “The
    Committee’s determination not to seek to involve the judiciary
    15
    reflected not only an intent to preserve the constitutional
    structure, but also the high probability that the courts would
    decline to rule on the merits of the case because it is . . . not the
    kind of controversy courts traditionally resolve.”
    Id. at 21
    0-11
    (emphasis added) (internal quotation marks omitted).
    The statutory regime for judicial enforcement of
    congressional subpoenas reflects this same judgment. Only the
    Senate has express statutory authority to enforce a subpoena in
    federal court, see 2 U.S.C. § 288d; In re U.S. Senate Permanent
    Subcomm. on Investigations, 
    655 F.2d 1232
    , 1238 & n.28 (D.C.
    Cir. 1981), but not if the suits involve executive-branch
    assertions of “governmental privilege,” 28 U.S.C. § 1365(a).
    As the law’s sponsors explained, the statute’s “purpose is to
    keep disputes between the executive and legislative branches
    out of the courtroom.” 142 CONG. REC. 19412 (1996)
    (statement of Sen. Specter); see also
    id. at 19413
    (statement of
    Sen. Levin) (similar). This case is just such a controversy;
    McGahn’s sole argument on the merits is that “Congress may
    not constitutionally compel the President’s senior advisers”—
    like McGahn—“to testify about their official duties.” McGahn
    Panel Br. 47 (internal quotation marks omitted).
    By privileging four recent lower-court decisions over 200
    years of tradition, the majority “needlessly disturb[s] the
    compromises and working arrangements that [the] branches
    themselves have reached.” Mazars, slip op. at 11 (cleaned up).
    “Congress and the Executive have . . . managed for over two
    centuries to resolve [information] disputes among themselves
    without the benefit of guidance from [the courts].”
    Id. The majority protests
    that its decision actually “preserv[es]” “the
    status quo ante between the branches,” Maj. Op. at 30, but that
    assertion is doubly wrong. The paucity of historical analogues
    to this suit belies the claim that the majority’s decision reflects
    the status quo. And the majority’s defense of congressional
    16
    standing does not preserve but displaces the system of
    accommodation that is the status quo. With litigation on the
    table, neither side has an incentive to cooperate. “Instead of
    negotiating over information requests,” Congress or the
    Executive Branch “could simply walk away from the
    bargaining table” and force a resolution by judges. Mazars, slip
    op. at 16. The inevitable result is that we will become courts
    not of last but of first resort.
    III
    Sometimes the temptation to wrongly expand our
    jurisdiction stems from “the natural urge to proceed directly to
    the merits of [an] important dispute and to ‘settle’ it for the sake
    of convenience and efficiency.” 
    Raines, 521 U.S. at 820
    . But
    here, the full court hurdles over Article III’s barriers only to
    decline to resolve the case. The majority remands the case to
    the panel to decide whether the Committee has a cause of action
    and whether it should prevail on the merits. Congress has
    already waited over fourteen months for a resolution; the court
    tells it to hurry up and wait some more. As in Mnuchin, I cannot
    agree with my colleagues’ decision to force the political
    branches to wait patiently while we work our way through
    these important cases. See Mnuchin, slip op. at 3-4 (Griffith, J.,
    dissenting). I would hold that the Committee lacks a cause of
    action to prosecute its case against McGahn.
    A
    In addition to demonstrating standing, the Committee must
    also show that it has a cause of action that supports an
    injunction compelling McGahn to testify. Our case law
    forecloses that argument.
    17
    “Prior to 1978 Congress had only two means of enforcing
    compliance with its subpoenas: [1] a statutory criminal
    contempt mechanism and [2] the inherent congressional
    contempt power.” In re Application of the U.S. Senate
    Permanent Subcomm. on 
    Investigations, 655 F.2d at 1238
    (footnote omitted). Neither means allowed for judicial
    enforcement of a subpoena. “Responding to this deficiency,
    Congress enacted [a] mechanism for civil enforcement of
    Senate subpoenas” in 1978.
    Id. (emphasis added). That
    law
    allows “the Senate [to] request a court order requiring [an]
    individual to comply with [a] subpoena.”
    Id. By my count,
    that
    comes to just three “means of enforcing compliance with
    [congressional] subpoenas”—a criminal contempt proceeding,
    an inherent contempt proceeding, and a civil suit authorized by
    statute.
    Id. But the statute
    that Congress passed in 1978 “does
    not . . . include civil enforcement of subpoenas by the House of
    Representatives.”
    Id. at 1238
    n.28. And Congress has passed
    no further statutes authorizing the House to bring such suits.
    Because the D.C. Circuit has identified only these three ways
    for Congress to enforce compliance with its subpoenas, that
    precedent forecloses the Committee’s efforts to litigate this
    case.
    B
    Even if the panel were not bound by this precedent on
    remand, the Committee would still lack a cause of action. The
    Committee argues that it has an implied cause of action under
    Article I, that it can invoke the traditional power of courts of
    equity to enjoin unlawful executive action, and that the
    Declaratory Judgment Act provides a separate basis for this
    suit. None suffices.
    Start with Article I. The Committee argues that it is
    “entitled under Article I to seek equitable relief to enforce a
    18
    subpoena . . . issued in furtherance of its constitutional power
    of inquiry.” Committee Panel Br. 34 (internal quotation marks
    omitted). But time and again, the Supreme Court has warned
    federal courts to hesitate before implying causes of actions—
    whether from a congressional statute or from the Constitution.
    See, e.g., Jesner v. Arab Bank, PLC, 
    138 S. Ct. 1386
    , 1402
    (2018); Ziglar v. Abbasi, 
    137 S. Ct. 1843
    , 1857 (2017);
    Alexander v. Sandoval, 
    532 U.S. 275
    , 286-87 (2001). “When a
    party seeks to assert an implied cause of action under the
    Constitution itself, . . . separation-of-powers principles are or
    should be central to the analysis,” 
    Ziglar, 137 S. Ct. at 1857
    ,
    and usually Congress “should decide” whether to authorize a
    lawsuit
    , id. (internal quotation marks
    omitted).
    In this case, Congress has declined to authorize lawsuits
    like the Committee’s twice over. First, Congress has granted an
    express cause of action to the Senate—but not to the House.
    See 2 U.S.C. § 288d. Second, the Senate’s cause-of-action
    statute expressly excludes suits that involve executive-branch
    assertions of “governmental privilege.” 28 U.S.C. § 1365(a).
    The expression of one thing implies the exclusion of the other,
    and authorizing the Committee to bring its lawsuit would
    conflict with two separate limitations on civil suits to enforce
    congressional subpoenas. We should not read these carefully
    drafted limitations out of the statute books.
    The Committee suggests that—even if Article I alone
    doesn’t provide a cause of action—the court may exercise its
    “traditional equitable powers” to grant relief. 
    Ziglar, 137 S. Ct. at 1856
    . But those powers remain “subject to express and
    implied statutory limitations,” Armstrong v. Exceptional Child
    Ctr., Inc., 
    575 U.S. 320
    , 327 (2015), and are further limited to
    relief that was “traditionally accorded by courts of equity,”
    Grupo Mexicano de Desarrollo S.A. v. All. Bond Fund, Inc.,
    
    527 U.S. 308
    , 319 (1999). Again, “implied statutory
    19
    limitations” foreclose suits by the House and suits that
    implicate a governmental privilege; this one checks both boxes.
    Anyway, there’s nothing “traditional” about the
    Committee’s claim. The Committee cannot point to a single
    example in which a chamber of Congress brought suit for
    injunctive relief against the Executive Branch prior to the
    1970s. Interbranch suits “lie[] far from the model of the
    traditional common-law cause of action at the conceptual core
    of the case-or-controversy requirement.” 
    Raines, 521 U.S. at 833
    (Souter, J., concurring in the judgment). While equity may
    be “flexible,” “that flexibility is confined within the broad
    boundaries of traditional equitable relief.” Grupo 
    Mexicano, 527 U.S. at 322
    . We cannot simply reference “equity” to justify
    a vast expansion of our authority to enforce congressional
    subpoenas.
    Finally, the Committee claims that the Declaratory
    Judgment Act allows it to bring suit. See 28 U.S.C. § 2201(a).
    This argument is even less persuasive. The Declaratory
    Judgment Act does not itself “provide a cause of action,” as the
    “availability of declaratory relief presupposes the existence of
    a judicially remediable right.” Ali v. Rumsfeld, 
    649 F.3d 762
    ,
    778 (D.C. Cir. 2011) (cleaned up); see also C&E Servs., Inc. of
    Wash. v. D.C. Water & Sewer Auth., 
    310 F.3d 197
    , 201 (D.C.
    Cir. 2002). That statute is “procedural only” and simply
    “enlarge[s] the range of remedies available in the federal
    courts.” Skelly Oil Co. v. Phillips Petroleum Co., 
    339 U.S. 667
    ,
    671 (1950) (internal quotation marks omitted). Because Article
    I does not create a “judicially remediable right” to enforce a
    congressional subpoena, the Committee cannot use the
    Declaratory Judgment Act to bootstrap its way into federal
    court. Thus, even if the Committee could establish the standing
    necessary to “get[] [it] through the courthouse door, [that] does
    not keep [it] there.” Make the Road N.Y. v. Wolf, 
    962 F.3d 612
    ,
    20
    631 (D.C. Cir. 2020). Without a cause of action to sustain it,
    the Committee’s suit must be dismissed.
    IV
    The majority’s opinion is a Pyrrhic victory for Congress.
    Courts have many virtues, but dispatch is not one of them. “To
    the extent that enforcement of congressional subpoenas is left
    to the courts, future administrations [will] now know that they
    can delay compliance for years,” all while avoiding the
    traditional political cost associated with refusing to negotiate
    with Congress in good faith. Josh Chafetz, Executive Branch
    Contempt of Congress, 76 U. CHI. L. REV. 1083, 1154 (2009).
    This case, and its unresolved companion in Mnuchin,
    illustrates the costs of delay. Despite agreeing to hear this case
    on an expedited schedule, more than fourteen months have
    passed since the House issued its subpoena. Yet final resolution
    of the Committee’s claim is nowhere in sight. And bear in mind
    that the majority says that this case presents a “discrete and
    limited” legal question. Maj. Op. at 27. How much longer will
    it take the courts to decide more intricate questions of power
    and privilege? The fact is that Congress has never successfully
    obtained information from an executive-branch official in a
    lawsuit. Indeed, our circuit previously declined to expedite the
    appeal of a legislative subpoena case because it could not be
    “fully and finally resolved by the Judicial Branch—including
    resolution by a panel and possible rehearing by this court en
    banc and by the Supreme Court—before [that]
    Congress end[ed]” and its subpoenas “expir[ed].” Comm. on
    the Judiciary of U.S. House of Representatives v. Miers, 
    542 F.3d 909
    , 911 (D.C. Cir. 2008).
    And the majority’s decision to open the courthouse doors
    to these futile lawsuits comes at a serious cost. The option of
    21
    litigation weakens Congress’s ultimate lever of accountability:
    its impeachment power. In the past, the House Judiciary
    Committee has treated the Executive Branch’s failure to
    cooperate in an investigation as grounds for an impeachment.
    See H.R. REP. NO. 116-346, at 155 & n.906 (2019) (President
    Trump); H.R. RES. NO. 93-625 (1973) (President Nixon). But
    once litigation is a viable option, the President can always
    defend against accusations of executive-branch stonewalling
    by turning around and reproaching Congress for bypassing the
    courts—just as the President did here. See Trial Memorandum
    of President Donald J. Trump, In Proceedings Before the
    United States Senate 49, 53 (Jan. 20, 2020). Today’s decision
    thus grants Congress the sluggish remedy of judicial
    superintendence only to blunt the most potent weapon in its
    arsenal.
    The court seems to think that the alternative—leaving
    these disputes to the traditional process of negotiation and
    accommodation—is even worse. But Congress has powerful
    and varied tools to deal with a recalcitrant Executive Branch. It
    may withhold appropriations, refuse to confirm presidential
    nominees, prevent the President from implementing his
    legislative agenda, and wield public opinion against the
    President. At the extreme, the Legislative Branch may hold
    uncooperative officers in contempt of Congress or even
    impeach them.
    The majority worries that these political remedies are
    “impracticable,” Maj. Op. at 34, and it offers judicial
    enforcement as a supplement. But judicial involvement cannot
    solve Congress’s problems when political tools fail. Courts
    cannot ensure that the Legislative Branch gets timely access to
    information from a dilatory Executive Branch; we take too
    long. Courts also cannot intervene without displacing the
    centuries-old system of negotiation, accommodation, and
    22
    (sometimes) political retaliation; one party or the other—likely
    an Executive Branch that benefits from delay—will walk away
    from the bargaining table and force litigation. And even if
    Congress eventually prevails in court, we cannot be sure that a
    “President [who] loses the lawsuit”—having already defied
    Congress and withstood political pressure—will “faithfully
    implement the [c]ourt’s decree.” 
    Windsor, 570 U.S. at 791
    (Scalia, J., dissenting).
    Worst of all, we cannot offer the political branches the
    remedy of judicial enforcement without squandering the
    precious reserve of public confidence that makes our
    judgments efficacious in the first place. Article III’s limitations
    are for the other branches’ protection, but they are for our
    protection too. Parties respect neither our “force” nor our “will”
    but our “judgment.” FEDERALIST NO. 78 (Alexander
    Hamilton). If we venture into this increasingly politicized
    territory, we risk undermining that neutrality and losing the
    public’s trust. We do neither ourselves nor the parties any
    favors by embarking down this path, and I would leave the
    political branches to resolve their disputes through the political
    process—as the Constitution demands. Respectfully, I dissent.
