    Before: MILLETT, KATSAS, and WALKER, Circuit Judges.
    Opinion for the Court filed by Circuit Judge KATSAS.
    KATSAS, Circuit Judge: Jamal Khashoggi, a prominent
    Saudi journalist, was murdered in a Saudi consulate in 2018,
    apparently on orders of the Saudi Crown Prince. Under the
    Freedom of Information Act, the plaintiffs here sought records
    about whether four United States intelligence agencies knew,
    before the murder, of an impending threat to Khashoggi. The
    agencies refused to confirm or deny whether they have any
    responsive records, on the ground that the existence or
    nonexistence of such records is classified information. We
    consider whether FOIA permitted this response.
    I
    FOIA generally requires federal agencies to disclose their
    records upon request, 
    5 U.S.C. § 552
    (a)(3)(A), subject to nine
    exemptions. Exemption 1 covers matters that are “specifically
    authorized under criteria established by an Executive order to
    be kept secret in the interest of national defense or foreign
    policy” and are “properly classified pursuant to such Executive
    order.” 
    Id.
     § 552(b)(1). The relevant executive order permits
    classification of information that “could reasonably be
    expected to cause identifiable or describable damage to the
    3
    national security” if disclosed, and that “pertains to” either
    “intelligence activities” or “intelligence sources or methods.”
    Exec. Order No. 13,526 § 1.4(c), 
    75 Fed. Reg. 707
    , 709 (Dec.
    29, 2009).
    To claim a FOIA exemption, an agency ordinarily must
    “acknowledge the existence of information responsive to a
    FOIA request and provide specific, non-conclusory
    justifications for withholding that information.” Roth v. DOJ,
    
    642 F.3d 1161
    , 1178 (D.C. Cir. 2011). But if “the fact of the
    existence or nonexistence of agency records” itself falls within
    a FOIA exemption, the agency may “refuse to confirm or deny
    the existence” of the requested records. Wolf v. CIA, 
    473 F.3d 370
    , 374 (D.C. Cir. 2007) (cleaned up). This is now known as
    a Glomar response, after the Central Intelligence Agency
    successfully refused to confirm or deny whether it had records
    about a ship called the Glomar Explorer. See Phillippi v. CIA,
    
    546 F.2d 1009
     (D.C. Cir. 1976). In considering a Glomar
    response, courts apply the “general exemption review
    standards established in non-Glomar cases.” Wolf, 
    473 F.3d at 374
    . An agency thus bears the burden to sustain a Glomar
    response. 
    5 U.S.C. § 552
    (a)(4)(B).
    If an agency has “officially acknowledged otherwise
    exempt information through prior disclosure,” it has “waived
    its right to claim an exemption with respect to that
    information.” ACLU v. CIA, 
    710 F.3d 422
    , 426 (D.C. Cir.
    2013). A plaintiff urging official acknowledgment must point
    to “specific information in the public domain that appears to
    duplicate that being withheld.” 
    Id. at 427
     (quoting Wolf, 
    473 F.3d at 378
    ). The prior disclosure must match the information
    requested, must be as specific, and must have been “made
    public through an official and documented disclosure.”
    Fitzgibbon v. CIA, 
    911 F.2d 755
    , 765 (D.C. Cir. 1990). To
    constitute official acknowledgment in the Glomar context, the
    4
    prior disclosure must confirm the existence or nonexistence of
    records responsive to the FOIA request. ACLU, 710 F.3d at
    427.
    II
    A
    Jamal Khashoggi, a Saudi national and United States
    resident, frequently and prominently criticized the Saudi
    government. On October 2, 2018, Khashoggi visited the Saudi
    consulate in Istanbul to obtain documents for his upcoming
    marriage. Inside the consulate, fifteen assailants injected him
    with a sedative, suffocated him to death, and dismembered his
    corpse with a bone saw. The murder provoked international
    outrage. The CIA and the United Nations both investigated it. 1
    On December 4, 2018, the CIA briefed Senate leaders. Shortly
    thereafter, Congress passed a joint resolution stating its belief
    that the Saudi Crown Prince had ordered the murder.
    Soon after the murder, a State Department spokesman
    fielded questions at a press conference. A reporter asked
    whether “the U.S. had intelligence, overheard or intercepted
    communications, suggesting that there was a threat to Mr.
    Khashoggi.” The spokesman responded: “[A]lthough I cannot
    comment on intelligence matters, I can say definitively the
    United States had no advanced knowledge of Jamal
    Khashoggi’s disappearance.” Press Briefing, Dep’t of State
    (Oct. 10, 2018), 2017-2021.state.gov/briefings/department-
    press-briefing-october-10-2018. Asked a second time whether
    1
    We base our account of Khashoggi’s death on findings from
    the United Nations investigation. See Human Rights Council, Annex
    to the Report of the Special Rapporteur on Extrajudicial, Summary
    or Arbitrary Executions: Investigation into the Unlawful Death of
    Mr. Jamal Khashoggi, U.N. Doc. A/HRC/41/CRP.1 (June 19, 2019).
    5
    “you” had prior knowledge of a threat, the spokesman
    answered that “we” had no such knowledge. Id. Asked a third
    time whether “the administration” had prior knowledge, the
    spokesman answered: “[A]lthough I can’t go into intelligence
    matters, I can definitively say that we had no knowledge in
    advance of Mr. Khashoggi’s disappearance.” Id.
    B
    This case concerns a FOIA request for records bearing on
    whether the intelligence community had prior knowledge of the
    threat.    The intelligence community includes eighteen
    executive agencies that “conduct intelligence activities
    necessary for the conduct of foreign relations and the
    protection of the national security of the United States.” Exec.
    Order No. 12,333 § 1.4, 
    46 Fed. Reg. 59,941
    , 59,943 (Dec. 4,
    1981); see also 
    50 U.S.C. § 3003
    (4) (listing intelligence-
    community agencies). The Director of National Intelligence is
    the head of the intelligence community, 
    id.
     § 3023(b)(1), and
    so may direct how the community “carries out its mission,”
    DiBacco v. U.S. Army, 
    795 F.3d 178
    , 198 (D.C. Cir. 2015).
    Exercising that authority, the Director promulgated
    Intelligence Community Directive 191. Under that Directive,
    any intelligence-community agency that “acquires credible and
    specific information indicating an impending threat of
    intentional killing, serious bodily injury, or kidnapping … shall
    have a duty to warn the intended victim.” Intelligence
    Community Directive 191, § E.1 (July 21, 2015). Each
    intelligence agency must “document and maintain records”
    regarding “duty to warn actions” such as the “method, means,
    and substance of any warning given.” Id. § F.13.
    The Knight First Amendment Institute at Columbia
    University and the Committee to Protect Journalists (CPJ)
    submitted FOIA requests for records relating to Khashoggi. On
    6
    October 19, 2018, Knight sent requests to the Department of
    State and four intelligence-community agencies—the CIA, the
    Office of the Director of National Intelligence, the National
    Security Agency, and the Federal Bureau of Investigation.
    From each of the five agencies, Knight requested “[a]ll records
    concerning the duty to warn under Directive 191 as it relates to
    Jamal Khashoggi.” J.A. 31. CPJ then filed an identical request.
    After receiving no response, Knight and CPJ sued.
    The intelligence agencies issued Glomar responses. They
    asserted that the existence or nonexistence of responsive
    records is classified information protected by Exemption 1.2
    Each agency gave essentially the same justification for the
    Glomar response: The existence of responsive records would
    signal that the agency had acquired credible and specific
    information of an impending threat to Khashoggi—i.e., that the
    agency had an intelligence interest in, and the ability to learn
    in advance about, the plot to murder the journalist. In turn, that
    could expose intelligence activities, sources, and methods. On
    the other hand, the nonexistence of responsive records would
    signal a blind spot in United States intelligence.
    Knight voluntarily dismissed its claims, and CPJ dismissed
    its claims against the State Department. The remaining
    parties—CPJ and the four intelligence agencies—cross-moved
    for summary judgment. The district court upheld the agencies’
    Glomar responses and granted them summary judgment.
    Knight First Amend. Inst. at Colum. Univ. v. CIA, 
    424 F. Supp. 3d 36
    , 42–46 (D.D.C. 2020).
    2
    The intelligence agencies also invoked Exemption 3 of FOIA,
    which covers matters that are exempted from disclosure by certain
    statutes. 
    5 U.S.C. § 552
    (b)(3). Because we uphold the Glomar
    responses under Exemption 1, we need not address Exemption 3.
    7
    III
    CPJ raises two arguments on appeal. First, it contends that
    the State Department officially acknowledged that no
    responsive records exist, thus precluding the intelligence
    agencies from making a Glomar response. Second, on the
    merits, it argues that Exemption 1 does not cover the existence
    or nonexistence of responsive records. Our standard of review
    is de novo. Wolf, 
    473 F.3d at 374
    .
    A
    We begin with the question of official acknowledgement.
    An agency waives any right to make a Glomar response by
    disclosing whether responsive records exist. ACLU, 710 F.3d
    at 426. Once an agency makes such an acknowledgment,
    “there is no value in a Glomar response. The secret is out.”
    Leopold v. CIA, 
    987 F.3d 163
    , 167 n.5 (D.C. Cir. 2021).
    To establish official acknowledgment, a plaintiff must
    identify information in the public domain that (1) matches the
    information requested, (2) is as specific, and (3) has “been
    made public through an official and documented disclosure.”
    Fitzgibbon, 
    911 F.2d at 765
    . CPJ invokes the State
    Department’s assertion that “the United States” had no advance
    knowledge of Khashoggi’s “disappearance” or of a threat to his
    life. Without prior knowledge of an impending threat to
    Khashoggi, CPJ reasons, the intelligence agencies could have
    had neither a duty to warn Khashoggi under Directive 191 nor
    any records related to the duty. For the sake of argument, we
    will assume that the State Department’s assertion that the
    United States had no prior knowledge of the attack matched an
    assertion that the intelligence agencies have no responsive
    records, and that it did so with the requisite degree of
    specificity. We will further assume that statements made in a
    press conference are sufficiently formal and considered to
    8
    constitute “official” acknowledgment by the agency making
    the statements. Nonetheless, we agree with the intelligence
    agencies that an official acknowledgment by the State
    Department cannot bind them.
    We do not “deem ‘official’ a disclosure made by someone
    other than the agency from which the information is being
    sought.” Frugone v. CIA, 
    169 F.3d 772
    , 774 (D.C. Cir. 1999).
    This is because, particularly “in the arena of intelligence and
    foreign relations,” a statement made by “one in a position to
    know” is given unique meaning and weight. Fitzgibbon, 
    911 F.2d at 765
     (cleaned up). While information from outside an
    agency may be viewed as “possibly erroneous,” confirmation
    by the agency itself “would remove any lingering doubts.”
    Frugone, 
    169 F.3d at
    774–75 (cleaned up); see also Ameziane
    v. Obama, 
    699 F.3d 488
    , 492 (D.C. Cir. 2012) (absent
    confirmation, foreign adversaries “would be left guessing”).
    Confirmation from within an intelligence agency also could
    have “an adverse effect on our relations with other countries,”
    who “might perceive themselves to be harmed by disclosure of
    their cooperation” with United States intelligence. Afshar v.
    Dep’t of State, 
    702 F.2d 1125
    , 1131 (D.C. Cir. 1983) (cleaned
    up).
    For these reasons, we have framed a general rule that
    “[d]isclosure by one federal agency does not waive another
    agency’s right to assert a FOIA exemption.” Mobley v. CIA,
    
    806 F.3d 568
    , 583 (D.C. Cir. 2015). Frugone is our leading
    case on this point. There, the Office of Personnel Management
    had officially acknowledged that the plaintiff formerly worked
    as a covert CIA employee, yet we upheld the CIA’s Glomar
    response to a FOIA request for his personnel records. 
    169 F.3d at
    774–75. We stressed the “untoward consequences that could
    ensue” if the CIA were “required either to confirm or to deny
    statements made by another agency.” 
    Id. at 775
    . For example,
    9
    a CIA admission that it had employed the plaintiff, a Chilean
    resident, “could cause greater diplomatic tension between
    Chile and the United States than do the informal, and possibly
    erroneous, statements already made by the OPM.” 
    Id.
    Alternatively, a CIA denial that it had employed the plaintiff
    “would lessen the burden facing a foreign intelligence agency
    attempting to track the CIA’s covert activities abroad.” 
    Id.
    Either way, the CIA’s own authoritative statement would cause
    greater diplomatic or security perils than statements by another
    agency on the same matter. We thus held that “only the CIA
    can waive its right to assert an exemption to the FOIA.” 
    Id.
    We have applied this rule in various cases and contexts. In
    Moore v. CIA, 
    666 F.3d 1330
     (D.C. Cir. 2011), we agreed with
    the district court that “the FBI lacked the authority to make an
    official acknowledgment on behalf of the CIA.” 
    Id. at 1332
    .
    Likewise, in Military Audit Project v. Casey, 
    656 F.2d 724
    (D.C. Cir. 1981), we held that disclosures by the National
    Science Foundation about the Glomar Explorer did not bar the
    CIA from invoking Exemption 1 to withhold documents about
    the vessel. 
    Id.
     at 742–45. We have also rejected attempts to
    establish an agency’s official acknowledgement based on
    disclosures by Congress, see Fitzgibbon, 
    911 F.2d at 766
    ;
    Salisbury v. United States, 
    690 F.2d 966
    , 971 (D.C. Cir. 1982),
    the media, EPIC v. NSA, 
    678 F.3d 926
    , 933 n.5 (D.C. Cir.
    2012), the agency’s former employees, Afshar, 
    702 F.2d at 1133
    ; Phillippi v. CIA, 
    655 F.2d 1325
    , 1330–31 (D.C. Cir.
    1981), and foreign governments, Mobley, 806 F.3d at 583.
    We have recognized one limited exception to the general
    rule: if a public disclosure is “made by an authorized
    representative of the agency’s parent,” it is “official” as to the
    subordinate agency. ACLU, 710 F.3d at 429 n.7. We have
    applied this exception in two situations. First, a disclosure by
    one component of an executive department may bind “another
    10
    component within” the same department. Marino v. DEA, 
    685 F.3d 1076
    , 1082 (D.C. Cir. 2012). So, if a Department of
    Justice prosecutor introduces certain records as evidence in
    court, other DOJ components may not claim FOIA exemptions
    as to those records. See id.; Davis v. DOJ, 
    968 F.2d 1276
    ,
    1279–82 (D.C. Cir. 1992). Second, the President, as the “head”
    of the entire Executive Branch, Trump v. Vance, 
    140 S. Ct. 2412
    , 2425 (2020); U.S. Const. Art. II § 1, cl. 1, may make
    official acknowledgments binding on its agencies. ACLU, 710
    F.3d at 429 n.7.
    This exception does not apply here. For one thing, the
    State Department is not a parent to any of the defendant
    intelligence agencies: the FBI is a component of the
    Department of Justice, see 
    28 U.S.C. § 531
    ; the NSA is a
    component of the Department of Defense, see Memorandum
    from Harry S. Truman to the Secretary of State and the
    Secretary of Defense (Oct. 24, 1952); and neither the ODNI nor
    the CIA has a parent agency. Nor can the State Department be
    considered an “authorized representative” of the President for
    purposes of this exception. Though the State Department is
    authorized to act for the President in the sense that it “wield[s]
    executive power on his behalf,” Seila Law LLC v. CFPB, 
    140 S. Ct. 2183
    , 2191 (2020), the same can be said of all executive
    agencies. If that were enough to allow one agency to make
    official acknowledgments binding on another, then the
    exception would entirely swallow up the rule.
    CPJ urges a different approach. Although the State
    Department is outside the chain-of-command of the other four
    agencies, CPJ seeks to link all of them through the intelligence
    community. One State Department component—its Bureau of
    Intelligence and Research—is a member of the intelligence
    community. 
    50 U.S.C. § 3003
    (4)(I). In turn, the intelligence
    community is an “integrated” group of agencies, Exec. Order
    11
    13,470 § 1.7, 
    73 Fed. Reg. 45,325
    , 45,333 (July 30, 2008), that
    “relies heavily on collaboration” among its members, Mission,
    Intel.gov, www.intelligence.gov/mission. The FOIA request at
    issue concerns a duty to warn imposed on all intelligence-
    community agencies. Intelligence Community Directive 191,
    § B.1. And the State Department’s public statement purported
    to speak on behalf of the entire United States. In these
    circumstances, CPJ urges us to attribute the statement to the
    entire intelligence community.
    We decline to extend official acknowledgement so far.
    For one thing, CPJ’s theory cannot be reconciled with our
    precedent. In Moore, we addressed a FOIA request to the FBI
    and CIA for records concerning a suspected member of the
    Icelandic Communist Party. 
    666 F.3d at 1331
    . The FBI had
    responded by releasing a report with “CIA-originated
    information” redacted, yet the CIA still issued a Glomar
    response. 
    Id. at 1332
    . Both agencies were members of the
    intelligence community, the subject of the FOIA request was a
    matter of their shared responsibility, and the disclosure by one
    agency spoke to information presumably within the other’s
    possession. Yet we agreed with the district court that “the FBI
    lacked the authority to make an official acknowledgment on
    behalf of the CIA,” 
    id.,
     and we reiterated our holding in
    Frugone that “only the CIA can waive its right to assert an
    exemption to the FOIA,” see 
    id.
     at 1333 n.4. To be sure, the
    plaintiff in Moore did not present the exact theory pressed here
    by CPJ. But we did hold that one intelligence agency cannot
    officially acknowledge a matter for another, and “the same
    issue presented in a later case in the same court should lead to
    the same result.” LaShawn A. v. Barry, 
    87 F.3d 1389
    , 1393
    (D.C. Cir. 1996) (cleaned up).
    In any event, we reject CPJ’s argument to the extent it is
    not foreclosed by precedent. Even putting Moore aside, CPJ’s
    12
    theory would substantially expand official acknowledgment.
    As explained above, we have given effect to acknowledgments
    only within the same executive Department or by the President.
    But under CPJ’s theory, any Department with a component
    agency in the intelligence community could bind all the
    intelligence agencies with generalized statements about what
    “the United States” knows or does not know. Departments
    with intelligence-community components include Defense,
    Energy, Homeland Security, Justice, Treasury, and State. See
    
    50 U.S.C. § 3003
    (4). Intelligence-community agencies include
    the CIA, NSA, ODNI, Defense Intelligence Agency, National
    Geospatial-Intelligence Agency, and National Reconnaissance
    Office, among many others. See 
    id.
     We see little basis for a
    rule permitting so many agencies to make official
    acknowledgments extending across large swaths of the entire
    Executive Branch.
    Moreover, the rationale for not imputing statements by one
    agency to another applies with greater force, not lesser, in the
    intelligence context. Not surprisingly, many of our cases
    rejecting cross-agency acknowledgment—including Frugone,
    Moore, Fitzgibbon, Mobley, and Military Audit Project—have
    involved the CIA. This case illustrates why. An official
    statement about what “the United States” did not know, made
    by an agency outside the intelligence community and with an
    express disclaimer as to “intelligence matters,” is one thing.
    An official statement about what the Central Intelligence
    Agency did or did not know, made by the CIA itself, would be
    quite another. Outside observers may ascribe more weight to
    an authoritative statement by the CIA itself, and its
    confirmation or denial may remove any lingering doubts and
    create further diplomatic problems. See, e.g., Afshar, 
    702 F.2d at
    1130–31; Ameziane, 699 F.3d at 492.
    13
    For these reasons, we hold that the statements made by the
    State Department spokesman do not foreclose the intelligence
    agencies from asserting their Glomar responses.
    B
    The merits of the Glomar responses here turn on whether
    Exemption 1 covers the question whether the four intelligence
    agencies have documents responsive to CPJ’s FOIA request.
    Exemption 1 permits agencies to withhold properly classified
    information, 
    5 U.S.C. § 552
    (b)(1), which includes information
    pertaining to intelligence activities, sources, or methods if
    disclosure “could reasonably be expected” to harm national
    security, Exec. Order No. 13,526 § 1.4, 75 Fed. Reg. at 709.
    Agencies may carry their burden of proof through
    declarations explaining why a FOIA exemption applies. See
    Oglesby v. U.S. Dep’t of Army, 
    79 F.3d 1172
    , 1178 (D.C. Cir.
    1996). Summary judgment is warranted if the declarations
    justify the nondisclosure “with reasonably specific detail” and
    are “not controverted by either contrary evidence in the record
    nor by evidence of agency bad faith.” Miller v. Casey, 
    730 F.2d 773
    , 776 (D.C. Cir. 1984) (cleaned up). Moreover, in the
    national-security context, “courts must accord substantial
    weight to an agency’s affidavit concerning the details of the
    classified status of the disputed record.” Wolf, 
    473 F.3d at 374
    (cleaned up); see Ctr. for Nat’l Sec. Studies v. DOJ, 
    331 F.3d 918
    , 927 (D.C. Cir. 2003) (CNSS) (“the judiciary owes some
    measure of deference to the executive in [FOIA] cases
    implicating national security, a uniquely executive purview”).
    In this context, an agency declaration “will always be
    speculative to some extent, in the sense that it describes a
    potential future harm,” so the agency’s “justification for
    invoking a FOIA exemption is sufficient if it appears logical or
    plausible.” Wolf, 
    473 F.3d at
    374–75 (cleaned up).

    Here, the intelligence agencies have logically and
    plausibly explained why the existence or nonexistence of
    responsive records is classified information. The four
    declarations express the same concerns. The existence of
    responsive records would show that the United States had an
    intelligence interest in, and the ability to gather information
    about, a particular person (Khashoggi) at a particular time
    (shortly before his murder), which could tend to reveal against
    whom and how surveillance might have been conducted.
    ODNI Decl. at 9–10 (J.A. 69–70); NSA Decl. at 9 (J.A. 92);
    CIA Decl. at 18–19 (J.A. 124–25); FBI Decl. at 9–10 (J.A.
    158–59). For example, “if a particular individual who is the
    target of IC surveillance mentioned Mr. Khashoggi and very
    specific information about him (e.g. an intent to harm Mr.
    Khashoggi) when that individual was using a particular method
    of communication, that individual would learn that they were
    being surveilled during a specific period of time and what
    method the IC was using to surveil them.” ONDI Decl. at 10
    (J.A. 70). On the other hand, the non-existence of responsive
    records would show a “blind spot” in United States
    intelligence, CIA Decl. at 19 (J.A. 125)—i.e., “a lack or dearth
    of underlying intelligence information” reflecting “gaps in IC
    capabilities, the success of evasive tactics taken by adversaries,
    and/or IC intelligence collection priorities,” NSA Decl. at 9
    (J.A. 92). Either response “would be of great interest to
    adversaries,” who “continually gather details regarding the
    [IC’s] specific intelligence capabilities, authorities, and
    interests” and “attempt to use this information to their
    advantage.” CIA Decl. at 19 (J.A. 125). For these reasons,
    revealing whether responsive documents exist would
    “reasonably be expected to result in at least serious damage to
    national security.” ODNI Decl. at 9 (J.A. 69).
    CPJ disputes the “logical or plausible” standard. It cites
    cases stating that a Glomar response is appropriate only where
    15
    confirming or denying the existence of responsive records
    “would”—not could—“itself cause harm cognizable under an
    FOIA exception,” ACLU, 710 F.3d at 426 (cleaned up), as well
    as one out-of-circuit case stating that Glomar responses require
    “a particularly persuasive affidavit,” Florez v. CIA, 
    829 F.3d 178
    , 182 (2d Cir. 2016) (cleaned up). CPJ argues the
    intelligence agencies therefore must show that confirming the
    existence or nonexistence of responsive records “would
    necessarily harm national security in every reasonably
    plausible circumstance.” Reply Br. at 21.
    CPJ’s legal analysis is flawed in several respects. To
    begin, it reads too much into our passing use of “would.” None
    of the cited cases mentions or turns on the difference between
    “would” and “could.” But those same cases do make clear that,
    in the Glomar context, “courts apply the general exemption
    review standards established in non-Glomar cases.” ACLU,
    710 F.3d at 426 (quoting Wolf, 
    473 F.3d at 374
    ). In non-
    Glomar cases, the applicability of Exemption 1 turns on
    whether disclosure of the record at issue “could reasonably be
    expected” to harm national security. Exec. Order No. 13,526
    § 1.4, 75 Fed. Reg. at 709 (emphasis added). Moreover, in the
    national-security context, our precedents assess only whether
    the government’s prediction of harm appears logical or
    plausible, taking into account the deference due to the
    Executive Branch in this area. See, e.g., ACLU, 710 F.3d at
    427; Wolf, 
    473 F.3d at
    374–75; CNSS, 
    331 F.3d at
    926–28.
    CPJ further contends that, if the intelligence agencies
    confirmed the existence of responsive records, foreign
    adversaries would have no way of knowing exactly what the
    records are or how they were acquired, and thus no reliable way
    to make conclusions about sources and methods. We are
    unpersuaded. For one thing, as the declarations lay out, the
    mere fact that an intelligence agency was monitoring threats to
    16
    specific individuals by specific governments at specific times
    would be useful information for foreign adversaries, even if the
    information revealed nothing further about specific sources and
    methods. Moreover, connections to specific intelligence
    agencies would themselves be revealing. For example, the
    NSA’s mission is to collect signals intelligence, NSA Decl. at
    3 (J.A. 86); if it had responsive documents, that would tend to
    reveal something about the collection of signals intelligence,
    despite CPJ’s speculation that agency files might consist of
    nothing more than anonymous tips or press accounts. In some
    cases, confirmation might also tend to reveal even more about
    sources and methods—if, for example, Khashoggi’s attackers
    had used very specific channels of communication to carry out
    their plot. See ODNI Decl. at 10 (J.A. 70). And even if targets
    could not deduce with certainty that they had been surveilled,
    a mere suspicion could induce them to take countermeasures.
    See FBI Decl. at 9 (J.A. 158) (to be effective, intelligence
    activities, methods, and sources must remain “unknown and
    unsuspected” (emphasis added)).         Furthermore, even if
    confirming the existence of responsive records might not
    always be harmful in cases like this one, CPJ does not dispute
    that confirming the nonexistence of responsive records would
    be harmful. Yet the agencies cannot pick and choose: if they
    confirm the existence of responsive records in cases where they
    exist, and issue Glomar responses in similar cases where no
    responsive records exist, the Glomar response would
    effectively signal confirmation that no responsive records
    exist—and thus lose its value as this became apparent over
    time. See ODNI Decl. at 10 (J.A. 70); NSA Decl. at 10–11
    (J.A. 93–94). For all these reasons, we see nothing illogical or
    implausible in the concerns raised by the intelligence agencies.
    The agencies’ concerns here also track ones that we
    credited in Wolf. There, the CIA issued a Glomar response to
    a FOIA request for all records related to a deceased Colombian
    17
    politician. See 
    473 F.3d at 372
    . We credited concerns that
    “confirming or denying an Agency interest in a foreign national
    reasonably could damage sources and methods by revealing
    CIA priorities, thereby providing foreign intelligence sources
    with a starting point for applying countermeasures against the
    CIA and thus wasting Agency resources.” 
    Id. at 377
    . And we
    did so without considering hypothetical scenarios like, for
    example, the possibility that the existence of responsive
    records might reflect nothing more than an anonymous tip or a
    press clipping.
    CPJ argues that the declarations here were not specific
    enough to support the Glomar responses. We disagree. In the
    national-security context, agency declarations need only
    “explain[] the justifications for nondisclosure with reasonably
    specific detail,” Freedom Watch, Inc. v. NSA, 
    783 F.3d 1340
    ,
    1344–45 (D.C. Cir. 2015) (cleaned up), which means enough
    detail to permit “meaningful” judicial review, Campbell v.
    DOJ, 
    164 F.3d 20
    , 30 (D.C. Cir. 1998). As our discussion
    above makes clear, the agencies readily satisfied that modest
    requirement. Moreover, we do not require a degree of
    specificity that would itself possibly “compromise intelligence
    methods and sources.” Military Audit Project, 
    656 F.2d at 751
    ;
    see Halperin v. CIA, 
    629 F.2d 144
    , 149 (D.C. Cir. 1980)
    (intelligence agency need not show an “identifiable concrete
    harm”). By demanding “specific details” about how particular
    targets could infer that they had been surveilled, Appellant’s
    Br. at 44, CPJ would have us disregard that settled principle.
    CPJ further argues that the intelligence agencies have
    taken inconsistent positions in different cases. It notes that, in
    another case, the CIA and ODNI acknowledged that they could
    not make a Glomar response to a FOIA request for records
    relating to Khashoggi’s death. Open Soc’y Just. Initiative v.
    CIA, 
    505 F. Supp. 3d 234
    , 241 (S.D.N.Y. 2020). But the
    18
    request in Open Society included records about the
    acknowledged, after-the-fact investigation into Khashoggi’s
    death conducted by the CIA. The request was thus far different
    from one seeking the existence of duty-to-warn documents that
    would indicate either prior knowledge of the threat to
    Khashoggi or the absence of such knowledge. As CPJ itself
    acknowledges, such prior knowledge “would only come via
    intelligence sources.” Reply Br. at 9. And unlike the later
    investigation and congressional briefing, no intelligence
    agency has confirmed or denied any prior knowledge.
    Finally, CPJ contends that the State Department’s press
    statement that “the United States” had no prior knowledge of
    Khashoggi’s “disappearance” undercuts the agencies’ Glomar
    response even if it does not constitute an official
    acknowledgment. But the agencies maintained their prediction
    of future harm even after taking that press statement into
    account. ODNI Decl. at 11 (J.A. 71); NSA Decl. at 11 (J.A.
    94); CIA Decl. at 20–21 (J.A. 126–27); FBI Decl. at 10 (J.A.
    159). This position was hardly illogical or implausible. For as
    explained above, a press statement from an agency outside the
    intelligence community, which expressly declined to
    “comment on intelligence matters,” is far different from
    confirmation (or denial) that a specific intelligence agency had
    (or did not have) credible and specific information of an
    impending threat to Khashoggi.

    The district court correctly concluded that the intelligence
    agencies’ Glomar responses were valid under Exemption 1.
