Judge LIVINGSTON dissents in a separate opinion.
STRAUB, Circuit Judge:This appeal arises from a request submitted to Defendant-Appellee Central Intelligence Agency (“CIA”) by Plaintiff-Appellant Sergio Florez (“Mr. Florez”), pursuant to the Freedom of Information Act (“FOIA”). See 5 U.S.C. § 552 et seq. Mr. Florez’s request, dated November 3, 2013, sought “the disclosure and release of any and all records between 1958 and 1990 related to and or mentioning [his] father, Armando J. Florez” (“Dr. Florez”). Joint App’x at 62. During the 1960s, Dr. Florez served in several high-level diplomatic roles on behalf of the Republic of Cuba, including as charge d’affaires1 in *181Washington, D.C. He defected to the United States in 1968, became an American citizen in 1979, and died in October 2013.
On November 20, 2013, the CIA answered Mr. Florez’s request with a so-called Glomar response,2 stating that it “can neither confirm nor deny the existence or nonexistence of records responsive to [Mr. Florez’s] request.” Id. at 70. It asserted that the existence or nonexistence of such records “is currently and properly classified and is intelligence sources and methods information” that is exempt from disclosure under FOIA. Id. On December 4, 2013, Mr. Florez timely filed an administrative appeal with the CIA’s Agency Release Panel.3
On February 18, 2014, while Mr. Flo-rez’s administrative appeal was pending, Mr. Florez timely filed the underlying action.4 The CIA and Mr. Florez filed cross-motions for summary judgment. On April 22, 2014, while the motions underwent briefing, the Agency Release Panel denied Mr. Florez’s administrative appeal.
On February 19, 2015, the United States District Court for the Southern District of New York (Sidney H. Stein, Judge) granted summary judgment in favor of the CIA and denied Mr. Florez’s cross-motion for summary judgment, holding that “the CIA’s Glomar response was justified and the existence of any records is exempt from disclosure under FOIA Exemption 1 (for classified national defense or foreign policy secrets) and Exemption 3 (for matters specifically exempted from disclosure by statute).” Florez v. CIA, No. 14-cv-1002, 2015 WL 728190, at *1 (S.D.N.Y. Feb. 19, 2015). This timely appeal followed.
During the pendency of this appeal, pursuant to a separate FOIA request, the Federal Bureau of Investigation (“FBI”) released several declassified documents pertaining to Dr. Florez on June 23, 2015, and one additional such document on July 24, 2015 (collectively, “FBI Disclosures”). Mr. Florez requested that the CIA revise its response to his FOIA request in light of the FBI Disclosures. The CIA reviewed the FBI Disclosures, but declined to alter its position that a Glomar response is supportable in these circumstances. See Letter from Preet Bharara, United States Attorney for the Southern District of New York, to Catherine O’Hagan Wolfe, Clerk *182of Court at 1, Florez v. CIA, No. 15-1055-cv (2d Cir. Dec. 18, 2015), ECF No. 57-1 [hereinafter “CIA Ltr.”].
DISCUSSION
Mr. Florez challenges the CIA’s Glomar response as inadequate under the FOIA, but we do not reach the merits of his challenge at this time. Because we find the FBI Disclosures relevant to the issues presented, we remand for the District Court to pass on the import of those documents in the first instance.
I. Standard of Review
By statute, a district court must review de novo an agency’s determination to withhold information requested under the FOIA, see 5 U.S.C. § 552(a)(4)(B); Main St. Legal Servs., Inc. v. Nat’l Sec. Council, 811 F.3d 542, 542 (2d Cir.2016), and we subsequently review de novo the district court’s ruling, see Ctr. for Constitutional Rights v. CIA, 765 F.3d 161, 166 (2d Cir.2014), cert. denied, — U.S. -, 135 S.Ct. 1530, 191 L.Ed.2d 559 (2015). “The government bears the burden of demonstrating that an exemption applies to each item of information it seeks to withhold, and all doubts as to the applicability of the exemption must be resolved in favor of disclosure.” Ctr. For Constitutional Rights, 765 F.3d at 166 (internal citations and quotation marks omitted). Such “[e]xceptions to FOIA’s general principle of broad disclosure of Government records have consistently been given a narrow compass.” Id. (internal quotation marks and ellipsis omitted).
“An agency may carry its burden by submitting declarations giving reasonably detailed explanations why any withheld documents fall within an exemption, and such declarations are accorded a presumption of good faith.” Id. (internal quotation marks omitted). We find a Glomar response justified only in “unusual circumstances, and only by a particularly persuasive affidavit.” N.Y. Times Co. v. Dep’t of Justice, 756 F.3d 100, 122 (2d Cir.2014) (internal quotation marks omitted); see also Halpern v. FBI, 181 F.3d 279, 295 (2d Cir.1999) (“[T]he good faith presumption that attaches to agency affidavits only applies when accompanied by reasonably detailed explanations of why material was withheld. Absent a sufficiently specific explanation from an agency, a court’s de novo review is not possible and the adversary process envisioned in FOIA litigation cannot function.”).
II. FOIA Exemptions 1 and 3
On the merits, which we do not reach in this opinion, this appeal presents an ordinary Glomar inquiry: whether the existence or nonexistence of documents, within the CIA’s possession and responsive to Mr. Florez’s request, is itself a fact exempt from disclosure under one of two FOIA exemptions. Because the relevancy of the FBI Disclosures is determined by the scope of the claimed exemptions, we briefly describe the two exemptions at issue.
The CIA relies upon FOIA Exemptions 1 and 3 to support its Glomar response. FOIA Exemption 1 “exempts from disclosure records 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 in fact properly classified pursuant to such Executive order.’ ” Ctr. for Constitutional Rights, 765 F.3d at 164 (quoting 5 U.S.C. § 552(b)(1)). The agency asserts that the existence or nonexistence of responsive records is information properly classified pursuant to § 1.1(4) of Executive Order 13,526, which permits classification of information that, if disclosed, “reasonably could be expected to result in damage to *183the national security, which includes defense against transnational terrorism, and the original classification authority is able to identify or describe the damage.” 75 Fed. Reg. 707, 707 (Dec. 29, 2009).5
FOIA Exemption 3 “permits the Government to withhold information from public disclosure provided that: (1) the information is ‘specifically exempted from disclosure by statute’; and (2) the exemption statute ‘requires that the matters be withheld from the public in such a manner as to leave no discretion on the issue’ or ‘establishes particular criteria for withholding or refers to particular types of matters to be withheld.’ ” ACLU v. Dep’t of Justice, 681 F.3d 61, 72 (2d Cir.2012) (quoting 5 U.S.C. § 552(b)(3)). Here, the CIA invokes Section 6 of the CIA Act of 1949, 50 U.S.C. § 3507 (exempting the CIA from any law that “require[s] the publication or disclosure of the organization, functions, names, official titles, salaries, or numbers of personnel employed by the Agency”), and Section 102A(i)(Z) of the National Security Act of 1947, 50 U.S.C. § 3024(i)(l) (protecting “intelligence sources and methods from unauthorized disclosure”).
III. FBI Disclosures
During the pendency of this appeal, the FBI Disclosures were brought to our attention by Mr. Florez and submitted to us by the CIA. Our threshold inquiry in this appeal is whether the FBI Disclosures should be considered in adjudicating this case. Mr. Florez, on one hand, urges us to consider the documents ourselves and con-elude that “the FBI release thoroughly undermine[s] the CIA’s position.” Letter from David E. McCraw, Attorney for Sergio Florez, to Catherine O’Hagan Wolfe, Clerk of Court at 1, Florez v. CIA, No 15-1055-cv (2d Cir. Dec. 18, 2015), ECF No. 53. The CIA, on the other hand, urges us to evaluate its response to Mr. Florez’s FOIA request “as of the time it was made and not at the time of [our] review,” CIA Ltr. at 1 (internal quotation marks omitted), and therefore ignore the FBI DíscIot sures in our analysis of the merits. If, however, we “determine that the FBI disclosures are relevant to the issues on appeal, the CIA respectfully requests that this case be remanded to the district court to allow the CIA to submit additional declarations addressing the FBI disclosures.” Id. at 3 n. 2. Accordingly, we first address whether the FBI Disclosures are relevant to the case. Answering that question in the affirmative, we next consider whether we should ignore the disclosures — resolving the merits based on the record as it existed at the time of Mr. Florez’s FOIA request — or remand the case to allow the District Court to weigh the significance of the documents in the first instance. Our precedent, judicial efficiency, and common sense all militate towards the latter and we therefore remand the case to the District Court.
A. Relevance
Due to issues of timing, the District Court below never had the opportunity to weigh the significance of the FBI Disclosures and, accordingly, on appeal, “we lack *184the benefit of an evaluation of this issue by the district court.” Official Comm. of Unsecured Creditors of WorldCom, Inc. v. SEC, 467 F.3d 73, 79 (2d Cir.2006) (Soto-mayor, /.). We therefore limit our inquiry at this juncture to whether the documents are relevant to the merits of this appeal, such that we need consider whether to accord the District Court the opportunity to assess them in the first instance. See Eric M. Berman, P.C. v. City of New York, 796 F.3d 171, 175 (2d Cir.2015) (per curiam) (“[I]t is this Court’s usual practice to allow the district court to address arguments in the first instance.” (internal quotation marks omitted)); see also, e.g., United States v. Salameh, 152 F.3d 88, 159 (2d Cir.1998) (per curiam) (concluding that the “best solution” for evaluating “newly discovered evidence” was for such evidence to “be addressed ... by the district court first”), cert. denied, 526 U.S. 1044, 119 S.Ct. 1345, 143 L.Ed.2d 508 (1999).
“Evidence is relevant if: (a) it has any tendency to make a fact more or less probable than it would be without the evidence; and (b) the fact is of consequence in determining the action.” Fed. R. Evid. 401. See also United States v. Certified Envtl. Servs., Inc., 753 F.3d 72, 90 (2d Cir.2014) (“[T]he definition of relevance under Fed. R. Evid. 401 is very broad”). More briefly stated, evidence is relevant if it has “appreciable probative value.” Relevant, Black’s Law Dictionary (10th ed. 2014); see also United States v. Litvak, 808 F.3d 160, 179-80 (2d Cir.2015). “Relevance is a legal determination.” United States v. Staniforth, 971 F.2d 1355, 1358 (7th Cir.1992) (Posner, J.) abrogated on other grounds by United States v. Wells, 519 U.S. 482, 117 S.Ct. 921, 137 L.Ed.2d 107 (1997). Conversely, it is “the province of the finder of fact to determine what weight to accord” such relevant evidence. Jim Beam Brands Co. v. Beamish & Crawford Ltd., 937 F.2d 729, 736 (2d Cir.1991). Accord Barefoot v. Estelle, 463 U.S. 880, 898, 103 S.Ct. 3383, 77 L.Ed.2d 1090 (1983) (“[T]he rules of evidence generally extant at the federal and state levels anticipate that relevant, unprivileged evidence should be admitted and its weight left to the factfinder, who would have the benefit of cross-examination and contrary evidence by the opposing party.”).
We conclude that the FBI Disclosures are relevant to the present Glomar inquiry. At minimum, the FBI Disclosures are germane to the CIA’s asserted rationale for asserting a Glomar response, which is that confirming the existence or non-existence of responsive records would confirm either the Agency’s interest or disinterest in Dr. Florez as an intelligence asset. Specifically, the documents appear to include the following revelations: (1) the FBI investigated Dr. Florez’s background and tracked his career development, official activities, and international relocations, see, e.g., CIA Ltr., Ex. A at 13, 27, 32, 36, 45-46; id. Ex. B at 1; (2) the FBI cultivated informants in order to obtain information concerning Dr. Florez, including material which pertained to both his professional and personal conduct, see, e.g., id. Ex. A at 6, 16-17, 19, 21, 23, 29, 35, 45-46; and (3) several other government departments and agencies provided to or received from the FBI information concerning Dr. Flo-rez, see, e.g., id. Ex. A at 25 (Department of State; Immigration & Naturalization Sendee (“INS”)), 27-28 (Department of State), 34-35 (Department of State; Navy’s Office of Naval Intelligence (“ONI”); Air Force’s Office of Special Investigations (“OSI”); Army’s Chief of Staff for Intelligence (“ACSI”)), 47 (same); id. Ex. B at 1 (INS).
These public disclosures have appreciable probative value in determining, under “the record as a whole,” “whether the jus*185tifications set forth in the [CIA’s] declaration are logical and plausible in this case.” Ctr. for Constitutional Rights, 765 F.3d at 168. The CIA’s declaration relies heavily on the import of masking the government’s intelligence interest (if any) in Dr. Florez and in maintaining complete secrecy as to whether any intelligence activities were focused on him. Though the FBI Disclosures do not reveal the CIA’s activities or involvement, they appear to suggest that multiple government departments and agencies were investigating, monitoring, and had an intelligence interest in Dr. Florez, and that the FBI cultivated informants to gather information about him. This now-public information may bear on the CIA’s position that the mere acknowl-edgement that it does or does not have possession of documents that reference Dr. Florez would harm the national security, or otherwise disclose Agency methods, functions, or sources.6
The Dissent disagrees that the FBI Disclosures even might bear on the sufficiency of the CIA’s Glomar response and therefore concludes that we should deem those disclosures irrelevant. See Dissent at 3-11. With respect to our dissenting colleague, we simply diverge on this point. Whereas the Dissent casually dismisses the FBI Disclosures as “disclosing] little regarding Dr. Florez,” see Dissent at 192, we believe the documents contain disclosures that bear upon whether the CIA is able to carry its burden in this case, to wit, “whether on the whole record the Agency’s judgment objectively survives the test of reasonableness, good faith, specificity, and plausibility.” Gardels v. CIA, 689 F.2d 1100, 1105 (D.C.Cir.1982).
The Dissent attempts to downplay the scope of the FBI Disclosures at every turn, shrugging them off as revealing nothing more than “that the FBI maintained some interest in Dr. Florez for some period of time.” See Dissent at 195. But to be clear, the disclosures in fact reveal a wealth of information, including that the FBI maintained an active interest in Dr. Florez for well over a decade, tracking the development of his career, including his foreign deployments and travel on behalf of the Cuban government in Europe, documenting his familial affiliations and personal affairs, and taking a particular interest in the fact he had grown disillusioned with the communist regime in Cuba and contemplated defection to the United States. These findings were shared with a myriad of other agencies, including, inter alia, the Department of State, the Navy’s Office of Naval Intelligence, the Army’s Chief of Staff for Intelligence, and the Air Force’s Office of Special Investigations, in addition to being circulated to the FBI’s Foreign Liaison Desk and FBI legal attachés in Madrid and Paris.7 We believe *186this information would be probative to a reasonable finder of fact attempting to discern the “reasonableness, good faith, specificity, and plausibility” of the CIA’s current Glomar response.
Rather than grapple with the full scope of the disclosures, the Dissent fixates on the fact that the disclosures emanate from the FBI, rather than the CIA. Although apparently hesitant to plainly say as much, the Dissent essentially argues that, under the official acknowledgment doctrine, the disclosures of other federal agencies — regardless of the extent to which they bear on the validity of another agency’s Glomar rationale — are never relevant and must be wholly disregarded. See Dissent at 195-96 & n. 7. This conclusion confuses the act of waiver — which we uniformly recognize as a privilege reserved to the agency asserting a Glomar response— with an agency’s independent obligation to “carry its burden by submitting declarations giving reasonably detailed explanations why any withheld documents fall within an exemption,” Ctr. For Constitutional Rights, 765 F.3d at 166 (internal quotation marks omitted), a burden which can only be carried when the agency’s declarations “are not called into question by contradictory evidence in the record.” Elec. Privacy Info. Ctr. v. Nat’l Sec. Agency, 678 F.3d 926, 931 (D.C.Cir.2012). In other words, a third party agency’s diselo-sures cannot waive the asserting agency’s right to a Glomar response, but such disclosures may well shift the factual groundwork upon which a district court assesses the merits of such a response.8
The official acknowledgment doctrine prohibits agencies from “providing] a Glomar response when the existence or nonexistence of the particular records covered by the Glomar response has been officially and publicly disclosed.” Wilner, 592 F.3d at 70. This waiver is limited only to official and public disclosures made by the same agency providing the Glomar response, and therefore does not “requir[e] [the agency] to break its silence” as a result of “statements made by another agency.” Frugone v. CIA, 169 F.3d 772, 775 (D.C.Cir.1999) (refusing to “treat the statements of the [Office of Personnel Management] ... as tantamount to an official statement of the CIA”).
But we do not impute the FBI’s decision to disclose information about Dr. Florez to the CIA, or suggest that the FBI Disclosures necessarily preclude the CIA’s right to assert a Glomar response. See Wilson v. CIA, 586 F.3d 171, 187 (2d Cir.2009) (declining to “infer official disclosure of information classified by the CIA from ... [the] release of information by another agency”). Rather, we simply conclude that the FBI Disclosures are relevant evidence — unavailable to the District Court at *187the time of its initial decision — bearing upon the sufficiency of the justifications set forth by the CIA in support of its Glomar response. Put simply, the official acknowledgment doctrine has no impact on our opinion in this case. The Dissent’s exclusive reliance on the official acknowl-edgement doctrine, to create out of whole cloth a rule limiting the evidence a district court may consider in a Glomar inquiry, only serves to demonstrate that it is promoting a solution of no applicability to this case.9
Rather than place an arbitrary limitation on the range of evidence a district court may consider in assessing the sufficiency of an agency affidavit filed in support of a Glomar response, our cases instruct that we accord “substantial weight” to such affidavits, but only “provided [that] the justifications for nondisclosure are not controverted by contrary evidence in the record .... ” Wilner, 592 F.3d at 68 (citation omitted). See also Elec. Privacy Info. Ctr., 678 F.3d at 931 (district courts, in Glomar case, may grant summary judgment on the basis of agency affidavits “if they are not called into question by contradictory evidence in the record”). Indeed, categorically excluding public documents as evidence when reviewing a Glo-mar response flies in the face of our own instruction that “[i]n evaluating an agency’s Glomar response ... [t]he court should attempt to create as complete a public record as is possible.” Wilner, 592 F.3d at 68 (internal quotation marks omitted). It defies reason to instruct a district court to deliberately bury its head in the sand to relevant and contradictory record evidence solely because that evidence does not come from the very same agency seeking to assert a Glomar response in order to avoid the strictures of FOIA. See Gardels, 689 F.2d at 1105 (“The test is not whether the court personally agrees in full with the CIA’s evaluation of the danger — rather, the issue is whether on the whole record the Agency’s judgment objectively survives the test of reasonableness, good faith, specificity, and plausibility in this field of foreign intelligence in which the CIA is expert and given by Congress a special role.” (emphasis added)).
Having determined that the FBI Disclosures are relevant to the merits of this case, we briefly address why remand is appropriate in this instance.
B. Remand
Although we conclude that the FBI documents are relevant to this case, our precedent nonetheless permits us to set aside the FBI Disclosures by adhering to the so-called “general rule” that “a FOIA decision is evaluated as of the time it was made and not at the time of a court’s review,” N.Y. Times, 756 F.3d at 110 n. 8. In our view, however, departure from that practice is warranted in this instance. Indeed, having now found the FBI Disclosures relevant to the sufficiency of the asserted Glomar rationale, the CIA *188asks us to proceed in this precise manner. See CIA Ltr. at 3 n.2.10
First, the policy underpinning the general rule does not apply here. As one of our sister circuits has explained, “[t]o require an agency to adjust or modify its FOIA response based on post-response occurrences could create an endless cycle of judicially mandated reprocessing each time some circumstance changes.” Bonner v. Dep’t of State, 928 F.2d 1148, 1152 (D.C.Cir.1991). This ease features no such judicially mandated reprocessing, as Mr. Florez, not the courts, requested that the CIA modify its FOIA response in light of the FBI Disclosures. Without being directed to do so, the CIA then reviewed those documents and determined not to alter its response to Mr. Florez’s FOIA request after due consideration. See CIA Ltr. at 1 (“The CIA has reviewed [the FBI Disclosures] and informed [Mr.] Florez’s counsel that they do not alter ... the CIA’s response .... ”). Thus, the CIA has already voluntarily undertaken and completed any “reprocessing” that could arise from remanding the case to allow the District Court to consider the FBI Disclosures.11
Second, consideration of the FBI Disclosures is “the most sensible approach” in this case. N.Y. Times, 756 F.3d at 110 n. 8 (rejecting the government’s' argument “that we cannot consider any official disclosures made after the District Court’s opinion,” and concluding that “[t]aking judicial notice” of “ongoing disclosures by the Government made in the midst of FOIA litigation” is “the most sensible approach”); accord ACLU v. CIA, 710 F.3d 422, 431 (D.C.Cir.2013) (taking notice of statements post-dating district court’s grant of summary judgment). If we were to proceed to the merits, and therefore potentially affirm the decision of the District Court, without considering the FBI Disclosures, we would accomplish little more than consign Mr. Florez to filing a fresh FOIA request, beginning the process anew with the FBI Disclosures in hand. Such an outcome makes little sense and would merely set in motion a multi-year chain of events leading inexorably back to a new panel of this Court considering the precise question presented here, perhaps in about two-and-a-half years (Mr. Florez’s FOIA request was submitted in November 2013). This delay would not serve the purposes of FOIA or the interests of justice, and it is inefficient to send Mr. Florez back to the end of the line.12 Because the' CIA has already reviewed the FBI docu*189ments and reaffirmed its Glomar response, we know how the CIA would respond to Mr. Florez’s renewed request, and there is no reason we should not take into account the reality in which this action proceeds.13
Third, remanding the case is in keeping with our general policy that the trial court should consider arguments — and weigh relevant evidence — in the first instance. See Quinones on Behalf of Quinones v. Chater, 117 F.3d 29, 36 (2d Cir.1997) (“As the [factfinder] did not address this evidence, we think it best to remand the case so that he can consider in the first instance what weight to accord it.”); Eric. M. Berman, P.C., 796 F.3d at 175; Salameh, 152 F.3d at 159; accord Sprint/United Mgmt. Co. v. Mendelsohn, 552 U.S. 379, 387, 128 S.Ct. 1140, 170 L.Ed.2d 1 (2008) (“Rather than assess the relevance of the evidence itself and conduct its own balancing of its probative value and potential prejudicial effect, the Court of Appeals should have allowed the District Court to make these determinations in the first instance, explicitly and on the record.”); Pullman-Standard v. Swint, 456 U.S. 273, 293, 102 S.Ct. 1781, 72 L.Ed.2d 66 (1982) (chastising the Court of Appeals for “failing] to remand for further proceedings” after determining that “the District Court had failed to consider relevant evidence” and instead making “its own determinations”).
In sum, proceeding to decision while willfully ignoring relevant materials would breed judicial inefficiency and produce an outcome contrary to that which might result from consideration of additional materials that — through no fault of Mr. Flo-rez’s — were unavailable to him at the time the FOIA request was made.
C. Jacobson Remand
In the interests of judicial economy and orderly resolution of this matter, we find prudent a limited remand to the District Court .pursuant to our practice under United States v. Jacobson, 15 F.3d 19, 22 (2d Cir.1994). The remand permits the District Court to reconsider its prior conclusion in light of the FBI Disclosures, and any additional materials it permits the parties to submit, see N.Y. Times, 756 F.3d at 110 n. 8 (explaining that the panel granted “the Government’s request for an opportunity to submit new material concerning public disclosures made after the District Court’s decision”), and then return its determination to us for consideration without the need for a new notice of appeal, briefing schedule, and reassignment to a new panel unfamiliar with the case. See, e.g., N.Y. State Citizens’ Coal. for Children v. Velez, 629 Fed.Appx. 92, 94 (2d Cir.2015) (summary order) (remanding pursuant to Jacobson “[b]ecause th[e] issue was not raised in the district court,” and “we conclude that it should be addressed in the first instance there”); United States v. Persad, 607 Fed.Appx. 83, 84 (2d Cir.2015) (summary order) (remanding pursuant to Jacobson “to address the disputed issue of Vermont law and practice in the first instance, and to conduct any further fact-finding that may be required”); Weifang Xinli Plastic Prods. Co. v. JBM Trading Inc., 553 Fed.Appx. 42, 44 (2d Cir.2014) (summary order) (remanding pursuant to Jacobson “for the district court to supplement the record”).
Accordingly, we remand to the District Court with instructions to enter an order stating whether its prior conclusion that the CIA adequately justified its Glomar response must be revised in light of the *190FBI Disclosures and any post-remand submissions.14 Within thirty days after such entry, either party may restore jurisdiction to this panel by filing a letter with the Clerk of this Court; this letter, not to exceed twenty double-spaced pages, should set forth the grounds for claiming error in the District Court’s decision and attach a copy of the order. Upon the filing of such a letter, the opposing party may file a response of the same maximum length within fourteen days. Oral argument will be scheduled at the panel’s discretion. If neither party files an initial letter within thirty days of the order’s entry, appellate jurisdiction will be restored automatically, and an order affirming the District Court will issue immediately.
CONCLUSION
We conclude that the FBI Disclosures are relevant to the issues raised in this appeal and that those documents should be considered in this case. Accordingly, we REMAND the case to the District Court with instructions to enter an order that states whether its prior conclusion that the CIA adequately justified its Glomar response must be revised in light of the FBI Disclosures and any post-remand submissions. Either party may restore appellate jurisdiction by filing a letter with the Clerk of this Court, as prescribed above. In the interests of judicial economy, any such reinstated, appeal will be assigned to this panel. The mandate shall issue forthwith.

CIA, No. 14-cv-1002, 2015 WL 728190, at *2 n. 3 (S.D.N.Y. Feb. 19, 2015); see also Oglesby v. Dep’t of Army, 920 F.2d 57, 62 (D.C.Cir.1990).
. This excerpt states one of the four requirements for classification pursuant to Executive Order 13,526. Mr. Florez does not dispute that the other three requirements for classification are met: "(1) an original classification authority is classifying the information; (2) the information is owned by, produced by or for, or is under the control of the United States Government; (3) the information falls within one or more of the categories of information listed in section 1.4 of this order,” 75 Fed. Reg. 707, 707 (Dec. 29, 2009), one of which is the "intelligence activities (including covert action) [and] intelligence sources or methods” category, id. at 709.
. Although the release of information from a third party agency may more directly bear upon whether another agency’s revelation of the existence or nonexistence of records “reasonably could be expected to result in damage to the national security,” 75 Fed. Reg. 707, 707 (Dec. 29, 2009), the determinative consideration under Exemption 1, there is no obvious reason why such third party disclosures cannot, in certain instances, likewise permit an inference contradicting an asserting agency’s Glomar response under Exemption 3. Indeed, in this case, beyond a separate boilerplate recitation of the Exemption 3 framework, see Joint App'x at 54-56, the CIA has proffered a single general rationale with respect to both Exemptions. See Joint App'x at 43-46. We leave it to the District Court, in the first instance, to assess “on the whole record” whether, in light of the recent FBI Disclosures, this rationale "objectively survives the test of reasonableness, good faith, specificity, and plausibility.” Gardels v. CIA, 689 F.2d 1100, 1105 (D.C.Cir.1982).
. The FBI Disclosures sometimes refer to these legal attachés as "legats.” See, e.g., FBI Disclosures at 40.
. Indeed, the Dissent appears to recognize as much, repeatedly explaining why these particular disclosures supposedly do not bear upon the CIA's Glomar rationale. For instance, the Dissent touts the fact that the FBI Disclosures “do not even mention the CIA,” Dissent at 193, or "even discuss the CIA or its activities,” Dissent at 191. Accordingly, the "documents here ... are simply not helpful in assessing the logic and plausibility” of the Glomar response at issue. Dissent at 192. See also Dissent at 194-95 ("[T]hese documents ... are simply not relevant to the question whether the CIA’s justification for its Glomar response in this case is plausible and makes sense” (emphasis in original)). This tacit acknowledgment that certain disclosures from a third party agency might weigh on the validity of a Glomar response (i.e., those expressly referring to the asserting agency or its activities) makes all the more puzzling both the Dissent's refusal to allow the District Court to weigh the facts in the first instance (as the Dissent itself has plainly done) and its insistence on propagating a per se rule barring consideration of third party disclosures on the sufficiency of an agency’s Glomar response.
. The Dissent attempts to extrapolate this limitation from the "animating principles” of the official acknowledgment doctrine, which, it contends, bar the " 'anomalous result’ that disclosures by one agency could open the door to compelled disclosure by another.” See Dissent at 196 n. 7 (quoting Frugone, 169 F.3d at 775). Suffice to say, we do not believe that allusion to the "animating principles” of an inapplicable doctrine serves to vindicate the Dissent’s proposed rule. Moreover, as already explained, this categorical limitation is at odds with the Dissent’s own acknowledgment that certain agency disclosures might, in some hypothetical instances, lead to disclosure by another agency. See, e.g., Dissent at 195.
. The agency unambiguously stated that if we "were to determine that the FBI disclosures are relevant to the issues on appeal/' it would “request[] that this case be remanded to the district court to allow the CIA to submit additional declarations addressing the FBI disclosures.” See CIA Ltr. at 3 n. 2. Having so determined, and for the additional reasons detailed herein, we accede to the agency's request.
. Indeed, that is likely why the agency itself asks us to remand the case to the District Court, if we find the FBI Disclosures relevant to the issues on appeal. See CIA Ltr. at 3 n. 2. Although the CIA has indicated that it may wish to submit additional declarations in support of its Giomar response on remand, such litigation is distinct from an agency’s often-lengthy processing of FOIA requests. See Adam Cohen, The Media That Need Citizens: The First Amendment and the Fifth Estate, 85 S. Cal. L. Rev. 1, 64 (2011) (describing agencies’ "generally lengthy processing delays” of FOIA requests).
.See Staff of H. Comm, on Oversight and Gov’t Reform, 114th Cong., FOIA Is Broken: A Report 36 (2016) ("Delays waste time and taxpayer money.”); Michael E. Tankersley, How the Electronic Freedom of Information Act Amendments of 1996 Update Public Access for the Information Age, 50 Admin. L. Rev. 421, 425 (1998) ("Despite the intention of the FOIA, the public's access to government information is inefficient, ineffective, and costly.” (internal quotation marks omitted)).
. Cf. Andrew Christy, The ACLU's Hollow FOIA Victory Over Drone Strikes, 21 Geo. Mason L. Rev. 1, 8 (2013) (noting a “startling disconnect between reality and the law in Glomar cases”).
. To be clear, we unequivocally pass no judgment on the sufficiency of the agency’s rationale at this juncture. Nor do we presume to tell the District Court what weight or significance it must attach to the FBI Disclosures. Further, we note that Congress has recently passed — and the President signed into law — the FOIA Improvement Act of 2016. See FOIA Improvement Act of 2016, Pub. L. No. 114-185, 130 Stat. 538 (2016). We express no view as to the effect, if any, of that Act upon FOIA law generally or the CIA’s Glomar response in this case. We leave these issues to the District Court, equipped with the relevant facts, in the first instance.
