    Before: HENDERSON, ROGERS and SRINIVASAN, Circuit
    Judges.
    Opinion for the court filed by Circuit Judge ROGERS.
    ROGERS, Circuit Judge: Andrew Miller appeals an order
    holding him in contempt for failing to comply with grand jury
    subpoenas served on him by Special Counsel Robert S.
    Mueller, III. He contends the Special Counsel’s appointment
    is unlawful under the Appointments Clause of the Constitution,
    and therefore the contempt order should be reversed. We
    affirm.
    I.
    The relevant statutory and regulatory authority relating to
    the context in which this appeal arises are as follows.
    A.
    The Attorney General is the head of the Department of
    Justice (“the Department”). 28 U.S.C. § 503. The Attorney
    General must be appointed by the President with the advice and
    consent of the Senate. 
    Id. Congress also
    created the position
    of Deputy Attorney General, who also must be appointed by
    the President with the advice and consent of the Senate. 
    Id. § 504.
    Congress has “vested” in the Attorney General virtually
    “[a]ll functions of other officers of the Department,” 
    id. § 509,
    and has empowered the Attorney General to authorize other
    Department officials to perform the functions of the Attorney
    General, 
    id. § 510.
    Congress has also authorized the Attorney
    General to commission attorneys “specially retained under the
    authority of the Department” as “special assistant to the
    Attorney General or special attorney,” 
    id. § 515(b),
    and
    provided “any attorney specially appointed by the Attorney
    3
    General under law, may, when specifically directed by the
    Attorney General, conduct any kind of legal proceeding, civil
    or criminal . . . which United States attorneys are authorized by
    law to conduct,” 
    id. § 515(a).
    Congress has also provided for
    the Attorney General to “appoint officials . . . to detect and
    prosecute crimes against the United States.” 
    Id. § 533(1).
    These statutes authorize the Attorney General to appoint
    special counsels and define their duties. See, e.g., United States
    v. Nixon, 
    418 U.S. 683
    , 694 (1974).
    At various times, independent counsels within the
    Department have conducted investigations and instituted
    criminal prosecutions pursuant to the Ethics in Government
    Act of 1978 (“the Act”). The Act authorized the appointment
    of an independent counsel upon a referral of a matter by the
    Attorney General to a three-judge court that could name an
    independent counsel. See 28 U.S.C. §§ 591–599 (expired). In
    1999, shortly before these provisions expired, the Department
    issued regulations to “replace” the Act with a procedure within
    the Executive Branch for appointing special counsels. Office
    of Special Counsel, 64 Fed. Reg. 37,038 (July 9, 1999); 28
    C.F.R. §§ 600.1–600.10. A special counsel is to be afforded
    wide discretion in the conduct of the investigation while
    “ultimate responsibility for the matter and how it is handled”
    resides in the Attorney General. 64 Fed. Reg. at 37,038.
    Under Department regulations, the Attorney General
    establishes the Special Counsel’s jurisdiction and determines
    whether additional jurisdiction is necessary to resolve the
    assigned matter or matters. 28 C.F.R. § 600.4(a), (b). The
    Special Counsel is required to “comply with the rules,
    regulations, procedures, practices and policies of the
    Department of Justice.” 
    Id. § 600.7(a).
    Additionally, the
    “Attorney General may request that the Special Counsel
    provide an explanation for any investigative or prosecutorial
    4
    step.” 
    Id. § 600.7(b).
    And the Special Counsel must notify the
    Attorney General of important events in the investigation under
    the Department’s Urgent Reports guidelines. 
    Id. § 600.8(b).
    The regulations provide that after review the Attorney General
    may conclude that a contemplated action is “so inappropriate
    or unwarranted under established Departmental practices that
    it should not be pursued.” 
    Id. § 600.7(b).
    During review, the
    Attorney General is to “give great weight” to the views of the
    Special Counsel. 
    Id. The regulations
    also address discipline, removal, and the
    resources for the Special Counsel’s investigation. The
    Attorney General has authority to discipline and to remove a
    Special Counsel for “misconduct, dereliction of duty,
    incapacity, conflict of interest, or for other good cause,
    including violation of Departmental policies.” 
    Id. § 600.7(d).
    The Attorney General establishes the budget for the Special
    Counsel’s investigation, and is to determine whether the
    investigation should continue at the end of each fiscal year. 
    Id. § 600.8(a)(1),
    (a)(2).
    B.
    The circumstances giving rise to this appeal began on
    March 2, 2017, when then-Attorney General Jeff Sessions
    recused himself “from any existing or future investigations of
    any matters related in any way to the campaigns for President
    of the United States.” Press Release No. 17-237, U.S. Dep’t of
    Justice, Attorney General Sessions Statement on Recusal (Mar.
    2, 2017). Department regulations provide that “no employee
    shall participate in a criminal investigation or prosecution if he
    has a personal or political relationship” with any person
    “involved in the conduct that is the subject of the investigation
    or prosecution.” 28 C.F.R. § 45.2. Attorney General Sessions
    announced in a press release that “[c]onsistent with the
    succession order for the Department of Justice,” the then-
    5
    Acting Deputy Attorney General Dana Boente “shall act as and
    perform the functions of the Attorney General with respect to
    any matters from which I have recused myself to the extent they
    exist.” Press Release No. 17-237. During testimony before the
    U.S. House of Representatives Permanent Select Committee on
    Intelligence on March 20, 2017, then-Director James Comey
    confirmed that the Federal Bureau of Investigation (“FBI”) was
    investigating the Russian Government’s efforts to interfere in
    the 2016 U.S. presidential election, including investigating the
    nature of any links between President Trump’s campaign and
    the Russian Government.
    On April 26, 2017, Rod J. Rosenstein was sworn in as
    Deputy Attorney General. By Appointment Order of May 17,
    2017, invoking “the authority vested in me as Acting Attorney
    General, including 28 U.S.C. §§ 509, 510, and 515,” General
    Rosenstein appointed Robert S. Mueller, III, to serve as Special
    Counsel for the Department to investigate the Russian
    Government’s efforts to interfere in the 2016 presidential
    election and “related matters” and to prosecute any federal
    crimes uncovered during the investigation. U.S. Dep’t of
    Justice, Off. of Dep. Att’y Gen., Order No. 3915-2017,
    Appointment of Special Counsel to Investigate Russian
    Interference With the 2016 Presidential Election and Related
    Matters (May 17, 2017) (“Appointment Order”). The
    Appointment Order stated that “Sections 600.4 through 600.10
    of Title 28 of the Code of the Federal Regulations” shall apply
    to the Special Counsel. 
    Id. Approximately one
    year later, Special Counsel Mueller
    issued multiple grand jury subpoenas requiring Andrew Miller
    to produce documents and to appear before the grand jury.
    After Miller failed to appear, the Special Counsel moved to
    compel his testimony and for an order to show cause why
    Miller should not be held in civil contempt for failure to appear
    6
    before the grand jury. Miller filed a motion to quash the
    subpoenas on the ground that the Special Counsel’s
    appointment violated the Appointments Clause of the
    Constitution, adopting by reference arguments made in a
    separate case by Concord Management and Consulting LLC
    (“Concord Management”), which was also being prosecuted by
    the Special Counsel. The district court denied the motion to
    quash and held Miller in civil contempt. In re Grand Jury
    Investigation, 
    315 F. Supp. 3d 602
    , 667 (D.D.C. 2018).
    II.
    On appeal, Miller challenges the authority of Special
    Counsel Mueller on the grounds that his appointment is
    unlawful under the Appointments Clause because: (1) the
    Special Counsel is a principal officer who was not appointed
    by the President with the advice and consent of the Senate;
    (2) Congress did not “by law” authorize the Special Counsel’s
    appointment; and (3) the Special Counsel was not appointed by
    a “Head of Department” because the Attorney General’s
    recusal from the subject matter of the Special Counsel’s
    investigation did not make the Deputy Attorney General the
    Acting Attorney General. This court’s review is de novo. See
    Recording Indus. Ass’n of America v. Verizon Internet Servs.,
    Inc., 
    351 F.3d 1229
    , 1233 (D.C. Cir. 2003).
    The Appointments Clause in Article II states:
    [The President] shall nominate, and by and with the
    Advice and Consent of the Senate, shall appoint
    Ambassadors, other public Ministers and Consuls,
    Judges of the supreme Court, and all other Officers of
    the United States, whose Appointments are not herein
    otherwise provided for, and which shall be established
    by Law: but the Congress may by Law vest the
    7
    Appointment of such inferior Officers, as they think
    proper, in the President alone, in the Courts of Law, or
    in the Heads of Departments.
    U.S. Const. art. II, § 2, cl. 2.
    A.
    As interpreted by the Supreme Court, the Appointments
    Clause distinguishes between “principal officers,” who must be
    nominated by the President with advice and consent of the
    Senate, and “inferior officers,” who may be appointed by the
    President alone, or by heads of departments, or by the judiciary,
    as Congress allows. Morrison v. Olson, 
    487 U.S. 654
    , 670–71
    (1988) (quoting Buckley v. Valeo, 
    424 U.S. 1
    , 132 (1976)).
    Thus, if Special Counsel Mueller is a principal officer, his
    appointment was in violation of the Appointments Clause
    because he was not appointed by the President with advice and
    consent of the Senate. Binding precedent instructs that Special
    Counsel Mueller is an inferior officer under the Appointments
    Clause.
    An inferior officer is one “whose work is directed and
    supervised at some level by others who were appointed by
    Presidential nomination with the advice and consent of the
    Senate.” Edmond v. United States, 
    520 U.S. 651
    , 663 (1997).
    In Edmond, the Supreme Court applied three factors to
    determine whether an officer was inferior: degree of oversight,
    final decision-making authority, and removability. 
    Id. at 663–
    66. According to Miller, those considerations point to Special
    Counsel Mueller being a principal, rather than inferior, officer
    because the Office of Special Counsel regulations impose
    various limitations on the Attorney General’s ability to exercise
    effective oversight of the Special Counsel.              But as
    foreshadowed in this court’s opinion in In re Sealed Case, 
    829 F.2d 50
    (D.C. Cir. 1987), a supervisor’s ability to rescind
    8
    provisions assuring an officer’s independence can render that
    officer inferior.     There, this court recognized that an
    independent counsel was an inferior officer because his office
    was created pursuant to a regulation and “the Attorney General
    may rescind this regulation at any time, thereby abolishing the
    Office of Independent Counsel.” 
    Id. at 56;
    see 
    Morrison, 487 U.S. at 721
    (Scalia, J., dissenting).
    The Attorney General, an officer appointed by the
    President with the advice and consent of the Senate, has
    authority to rescind at any time the Office of Special Counsel
    regulations or otherwise render them inapplicable to the
    Special Counsel. Unlike the independent counsel in 
    Morrison, 487 U.S. at 660
    –64, whose independence and tenure protection
    were secured by Title VI of the Ethics in Government Act,
    Special Counsel Mueller is subject to greater executive
    oversight because the limitations on the Attorney General’s
    oversight and removal powers are in regulations that the
    Attorney General can revise or repeal, see 5 U.S.C. § 553(a)(2),
    (b)(A), (b)(B), (d)(3); absent such limitations, the Attorney
    General would retain plenary supervisory authority of the
    Special Counsel under 28 U.S.C. § 509. Furthermore, even if
    at the time of the appointment of Special Counsel Mueller only
    the Attorney General could rescind the regulations, the Acting
    Attorney General could essentially accomplish the same thing
    with specific regard to Special Counsel Mueller by amending
    his Appointment Order of May 17, 2017, to eliminate the
    Order’s good cause limitations on the Special Counsel’s
    removal (on which Miller focuses particular attention).
    In either event, Special Counsel Mueller effectively serves
    at the pleasure of an Executive Branch officer who was
    appointed with the advice and consent of the Senate. See 28
    U.S.C. §§ 509, 515(a), 516; Free Enter. Fund v. Pub. Co.
    Accounting Oversight Bd., 
    561 U.S. 477
    , 509 (2010);
    9
    Appointment Order (May 17, 2017). The control thereby
    maintained means the Special Counsel is an inferior officer.
    See Sealed 
    Case, 829 F.2d at 56
    –57. Miller’s contention that
    Special Counsel Mueller is a principal officer under the
    Appointments Clause thus fails.
    B.
    The question whether Congress has “by law” vested
    appointment of Special Counsel Mueller in the Attorney
    General has already been decided by the Supreme Court. In
    United States v. Nixon, 
    418 U.S. 683
    , 694 (1974), the Court
    stated: “[Congress] has also vested in [the Attorney General]
    the power to appoint subordinate officers to assist him in the
    discharge of his duties. 28 U.S.C. §§ 509, 510, 515, 533.” In
    acting pursuant to those statutes, the Court held, the Attorney
    General validly delegated authority to a special prosecutor to
    investigate offenses arising out of the 1972 presidential
    election and allegations involving President Richard M. Nixon.
    
    Id. Miller contends,
    unpersuasively, that the quoted sentence
    in 
    Nixon, 418 U.S. at 694
    , is dictum because the issue whether
    the Attorney General had statutory authority to appoint a
    special prosecutor was not directly presented and the Supreme
    Court did not analyze the text of the specific statutes. It is true
    that a statement not necessary to a court’s holding is dictum.
    See City of Okla. City v. Tuttle, 
    471 U.S. 808
    , 842 (1985);
    Sierra Club v. EPA, 
    322 F.3d 718
    , 724 (D.C. Cir. 2003);
    Martello v. Hawley, 
    300 F.2d 721
    , 722–23 (D.C. Cir. 1962).
    But Miller misreads Nixon, for the Supreme Court was
    presented with the question whether a justiciable controversy
    existed. When the Special Prosecutor issued a subpoena to the
    President to produce certain recordings and documents, the
    President moved to quash the subpoena, asserting a claim of
    executive privilege, 
    id. at 688,
    and maintained the claim was
    10
    nonjusticiable because it was “intra-executive” in character, 
    id. at 689.
    The Supreme Court held there was a justiciable
    controversy because the regulations issued by the Attorney
    General gave the Special Prosecutor authority to contest the
    President’s invocation of executive privilege during the
    investigation. 
    Id. at 695–97.
    In this analysis, the Attorney
    General’s statutory authority to issue the regulations was a
    necessary antecedent to determining whether the regulations
    were valid, and, therefore, was necessary to the decision that a
    justiciable controversy existed. The Supreme Court’s quoted
    statement regarding the Attorney General’s power to appoint
    subordinate officers is, therefore, not dictum. Moreover, under
    this court’s precedent, “carefully considered language of the
    Supreme Court, even if technically dictum, generally must be
    treated as authoritative.” United States v. Fields, 
    699 F.3d 518
    ,
    522 (D.C. Cir. 2012).
    Furthermore, in Sealed 
    Case, 829 F.2d at 52
    –53, this court
    recognized that the statutory scheme creating the Department
    vests authority in the Attorney General to appoint inferior
    officers to investigate and to prosecute matters with a level of
    independence. There, the Attorney General appointed an
    independent counsel and promulgated regulations to create an
    office to investigate whether Lieutenant Colonel Oliver L.
    North and other officials violated federal criminal law in
    connection with the shipment or sale of military arms to Iran
    and the transfer or diversion of funds connected to any sales
    (referred to as the Iran/Contra matter). The Attorney General
    also authorized the independent counsel to prosecute any
    violations of federal criminal laws uncovered during
    investigation of the Iran/Contra matter. 
    Id. at 52.
    North
    refused to comply with a grand jury subpoena, arguing that the
    independent counsel’s appointment was invalid. 
    Id. at 54–55.
    This court disagreed:
    11
    We have no difficulty concluding that the Attorney
    General possessed the statutory authority to create the
    Office of Independent Counsel: Iran/Contra and to
    convey to it the ‘investigative and prosecutorial
    functions and powers’ described in . . . the
    regulation. . . . While [5 U.S.C. § 301 and 28 U.S.C.
    §§ 509, 510, and 515] do not explicitly authorize the
    Attorney General to create an Office of Independent
    Counsel virtually free of ongoing supervision, we read
    them as accommodating the delegation at issue here.
    
    Id. at 55.
    The issue before the court was whether the independent
    counsel was authorized to investigate and to prosecute officials
    in regard to the Iran/Contra matter. As such, the Attorney
    General’s authority to appoint an independent counsel was
    antecedent to deciding whether the Attorney General validly
    delegated authority to the independent counsel. The court’s
    quoted statements regarding the Attorney General’s statutory
    authority to appoint an independent counsel are, therefore, not
    dicta as Miller suggests.
    To the extent Miller incorporates arguments of Amicus
    Curiae Concord Management, he maintains that in Sealed Case
    this court held only that the Attorney General had authority to
    delegate powers to an already appointed position inside the
    Department, not authority to appoint a new special counsel
    outside of the Department. The court expressly noted that the
    statutory scheme authorized the Attorney General to delegate
    powers to “others within the Department of Justice.” 
    Id. at 55
    n.29. Miller is correct that in that case, the independent counsel
    had two parallel appointments: one from the Attorney General
    to the Office of Independent Counsel: Iran/Contra and an
    earlier one from a Special Division under the Ethics in
    12
    Government Act, 28 U.S.C. § 593(b). But this court explicitly
    declined to address whether the independent counsel’s initial
    appointment under the Act was valid, thereby avoiding the
    need to consider any constitutional questions raised by the Act.
    Sealed 
    Case, 829 F.2d at 55
    –56, 62; see Appellee Br. 34.
    Therefore, this court assumed that the independent counsel did
    not already hold a position inside the Department when it held
    that the Attorney General’s appointment of him to the Office
    of Independent Counsel: Iran/Contra was valid. That analysis
    applies equally to the facts of the instant case.
    Because binding precedent establishes that Congress has
    “by law” vested authority in the Attorney General to appoint
    the Special Counsel as an inferior officer, this court has no need
    to go further to identify the specific sources of this authority.
    See generally Grand Jury 
    Investigation, 315 F. Supp. 3d at 651
    –58; see also 28 U.S.C. §§ 515(b), 533(1). Miller’s cursory
    references to a “clear statement” argument he presented to the
    district court are insufficient to preserve that issue for appeal
    and it is forfeited. New York Rehab. Care Mgmt., LLC v. NLRB,
    
    506 F.3d 1070
    , 1076 (D.C. Cir. 2007); Carducci v. Regan, 
    714 F.2d 171
    , 177 (D.C. Cir. 1983); see United States v. Olano, 
    507 U.S. 725
    , 733 (1993).
    C.
    The statutory and regulatory scheme demonstrate, contrary
    to Miller’s contention, that at the time of Special Counsel
    Mueller’s appointment, Acting Attorney General Rosenstein
    was the “Head of Department” under the Appointments Clause
    as to the matter on which the Attorney General was recused.
    The Attorney General is the head of the Department of Justice,
    28 U.S.C. § 503, and an Acting Attorney General becomes the
    head of the Department when acting in that capacity because
    an acting officer is vested with the same authority that could be
    exercised by the officer for whom he acts, Ryan v. United
    13
    States, 
    136 U.S. 68
    , 81 (1890); Keyser v. Hitz, 
    133 U.S. 138
    ,
    145–46 (1890); see also Acting Officers, 
    6 Op. O.L.C. 119
    , 120
    (1982).
    Miller’s view that the Attorney General’s recusal did not
    make the Deputy Attorney General the “Acting” Attorney
    General, and, therefore, the Deputy Attorney General lacked
    authority to appoint Special Counsel Mueller as an inferior
    officer, ignores the statutory scheme. Section 508(a) of Title
    28 provides: “In case of a vacancy in the office of Attorney
    General, or of his absence or disability, the Deputy Attorney
    General may exercise all the duties of that office.” The word
    “disability” means the “inability to do something” or “lack of
    legal qualification to do a thing.” Webster’s Third New
    International Dictionary 642 (1981). Congress is presumed to
    use words to have their ordinary meaning absent indication to
    the contrary. Russello v. United States, 
    464 U.S. 16
    , 21 (1983);
    Perrin v. United States, 
    444 U.S. 37
    , 42 (1979).
    Miller would qualify Congress’s meaning as limited to a
    “wholesale absence or disability, not a recusal to act on a single
    issue.” Appellant Br. 36–41. His interpretation is contrary to
    the structure Congress created for the Department whereby the
    Deputy Attorney General can carry on when the Attorney
    General is unable to act on a matter. A statute and Department
    regulation disqualify any officer or Department employee from
    participating in an investigation or prosecution that may
    involve “a personal, financial, or political conflict of interest,
    or the appearance thereof.” 28 U.S.C. § 528; see 28 C.F.R.
    § 45.2(a). Department regulation 28 C.F.R. § 45.2(a) bars
    involvement where there is a conflict of interest, and then-
    Attorney General Sessions invoked that regulation as to the
    investigation of Russia’s interference in the 2016 presidential
    campaign. Hon. Jeff Sessions, Attorney General, Prepared
    Remarks to the United States Senate Select Committee on
    14
    Intelligence (June 13, 2017). At the time of the Special
    Counsel’s appointment then, the Attorney General had a
    “disability” because he lacked legal qualification to participate
    in any matters related to that conflict. See 
    Russello, 464 U.S. at 21
    ; Webster’s Third New International Dictionary 642
    (1981). Under Miller’s view, there could be no Attorney
    General, acting or otherwise, to be in charge of the matter.
    Our understanding of Congress’s use of the word
    “disability” in Section 508 accords with courts’ interpretations
    of Rule 25(a) of the Federal Rules of Criminal Procedure. Rule
    25(a) provides that if a judge cannot proceed to preside at a trial
    due to “death, sickness, or other disability,” another judge may
    complete the trial. Courts have interpreted “disability” to
    include recusal. In re United States, 
    614 F.3d 661
    , 661 (7th
    Cir. 2010); United States v. Hall, 
    171 F.3d 1133
    , 1153 (8th Cir.
    1999); United States v. Sartori, 
    730 F.2d 973
    , 976 (4th Cir.
    1984); Bennett v. United States, 
    285 F.2d 567
    , 572 (5th Cir.
    1960). The authorities Miller cites to support his interpretation
    — the Vacancies Act of 1868 and Moog Inc. v. United States,
    Misc. No. Civ-90-215E, 
    1991 WL 46518
    (W.D.N.Y. Apr. 1,
    1991) — provide no basis to conclude Congress intended a
    different meaning of “disability” in Section 508(a). In
    challenging the validity of the analogy on the basis that all
    federal judges have been appointed by the President with the
    advice and consent of the Senate, 28 U.S.C. § 133, Miller
    overlooks that by statute so is the Deputy Attorney General, 28
    U.S.C. § 504.
    Therefore, the Attorney General’s single-issue recusal is a
    “disability” that created a vacancy that the Deputy Attorney
    General was eligible to fill. Miller points to no basis on which
    this court could conclude that Congress did not intend the term
    “disability” to have its ordinary meaning. See 
    Russello, 464 U.S. at 21
    .

    Still Miller maintains that Section 508 does not make the
    Deputy Attorney General an “acting” officer but only
    authorizes the Deputy Attorney General to perform the duties
    of the Attorney General’s office and the Attorney General
    remains the “Head of Department” for Appointments Clause
    purposes. Congress has authorized the Deputy Attorney
    General to perform “all the duties of th[e] office” in case of a
    vacancy, 28 U.S.C. § 508(a), such that the Deputy becomes the
    “Acting” Attorney General. As to the recused matter, the
    Acting Attorney General has authority to appoint inferior
    officers because that is part of the authority that could be
    exercised by the Attorney General. Miller’s position that the
    Deputy Attorney General only becomes the “Acting” Attorney
    General if the Federal Vacancies Reform Act, 5 U.S.C. § 3345,
    is triggered — and that the Act is triggered, he maintains, only
    upon a complete inability to perform the functions and duties
    of the Attorney General’s office — overlooks that the Act
    explicitly provides it is not the exclusive means to designate an
    “acting” official. 5 U.S.C. § 3347(a)(1)(B). Other statutes may
    temporarily authorize an officer or employee to perform the
    functions and duties of a specified office. 
    Id. Miller does
    not
    explain why 28 U.S.C. § 508 is not such a statute that
    temporarily authorizes an officer to temporarily perform the
    duties of the Attorney General. See S. Rep. No. 105-250, at
    15–16 (1998); see also Noel Canning v. NLRB, 
    705 F.3d 490
    ,
    511 (D.C. Cir. 2013), aff’d on other grounds, 
    134 S. Ct. 2550
    (2014). Therefore, Special Counsel Mueller was properly
    appointed by a head of Department, who at the time was the
    Acting Attorney General.
    Because the Special Counsel is an inferior officer, and the
    Deputy Attorney General became the head of the Department
    by virtue of becoming the Acting Attorney General as a result
    of a vacancy created by the disability of the Attorney General
    16
    through recusal on the matter, we hold that Miller’s challenge
    to the appointment of the Special Counsel fails. Accordingly,
    we affirm the order finding Miller in civil contempt.
