War Secretary Pete Hegseth has fired Army Lt. Gen. Brett Sylvia, the Joint Staff's director for strategy, plans and policy (J-5), after an Air Force investigation into alleged leaks of classified information about the Iran war and the Russia-Ukraine war. The ouster was first reported by The Atlantic on the evening of Wednesday, Oct. 28, 2026, and the Pentagon publicly confirmed a personnel action and a Justice Department referral on Thursday, Oct. 29.
According to Axios, citing a U.S. official and an internal report, Sylvia admitted on video to sharing classified information with two reporters over roughly a year after failing four polygraph examinations. Other outlets, citing a Pentagon official, reported three failed polygraphs. Two Pentagon sources told CBS News the firing was tied to the polygraphs but said the accusations are not true. Sylvia did not respond to a Fox News request for comment.
The case lands as President Donald Trump weighs resuming major strikes on Iran after the Nov. 3 midterm elections, and it has opened a second fight over whether the Pentagon itself broke privacy law by publicizing the polygraph results.

What Happened
Sylvia had led the J-5 directorate for about 11 months, ABC News reported. A 1994 West Point graduate with more than three decades in the Army, he ran a directorate that develops military strategy and advises the chairman of the Joint Chiefs of Staff, Fox News reported.
A senior Pentagon official said Sylvia was fired for "severe misconduct" and that the case was referred to the Justice Department, ABC News reported. The official said he failed three polygraph exams in an investigation of leaks to journalists, CBS News reported, and CBS said in a follow-up that it could not verify the claims.
Parnell did not name Sylvia, but said in a statement on X that the department took "necessary personnel action" after "an extensive Air Force OSI investigation." He added: "Classified information is not personal property," CBS News reported.
"Our commitment was not an empty promise. We vowed to find you, and we meant it." — Sean Parnell, chief Pentagon spokesman, as quoted by Fox News
The most detailed account came from Axios, which cited an internal OSI report. According to UNITED24 Media's summary of that report, Sylvia's contacts with reporters began as early as June 2025 and continued over Signal and in person, UNITED24 Media reported.
The report alleges he met a reporter at a Silver Diner (UNITED24 says twice; other summaries say once) in Arlington after that journalist's Pentagon access was revoked, used notes from a classified report, and verbally described U.S. assistance to Ukraine. Investigators also reviewed Signal messages with a second reporter, believed to concern Iran, and said Sylvia deleted the thread; he told investigators he believed he erased it by accident, according to the same account. Ecker Geopolitics could not independently verify the contents of the internal report.
Sylvia was accused of meeting journalists outside the Pentagon after Hegseth required reporters to be escorted inside the building, Fox News reported. Trump said Thursday that Sylvia is going to have "big problems, long term problems."
The Joint Staff first issued a statement expressing "deepest gratitude" for Sylvia's "distinguished" service, then withdrew it, saying it "did not appropriately reflect the full circumstances," ABC News reported.

Who's Involved
- Lt. Gen. Brett Sylvia: Former J-5 director and former commander of the 101st Airborne Division (July 2023 to May 2025), according to his Joint Chiefs biography. A combat veteran of Iraq and Afghanistan who received a Purple Heart. He did not respond to Fox News' request for comment.
- Pete Hegseth: War Secretary, who has made hunting leakers a priority.
- Sean Parnell: Chief Pentagon spokesman, who said the department has "zero tolerance for the intentional, unauthorized disclosure of classified information," per ABC News.
- Air Force OSI: Conducted the investigation.
- Justice Department: Declined to comment on Sylvia but cited "ongoing investigations related to possible leaks of classified information," per Fox News.
- Elbridge Colby: Pentagon policy chief; The Atlantic reported Hegseth lost confidence in Sylvia amid tensions with Colby, according to Fox News.
The Ground Picture
The J-5 is one of the Joint Staff's most important directorates alongside the J-3 operations shop, ABC News noted. Fox News reported that a U.S. official said Sylvia was not a central planner of the Iran war, which is run by U.S. Central Command under Adm. Brad Cooper, and that the J-5 has reportedly been sidelined since spring.
Sylvia is the second J-5 director removed under Hegseth. The firing also follows the removal of three Pentagon officials in a 2025 leak probe, Dan Caldwell, Darin Selnick and Colin Carroll, none of whom were charged, CBS News reported.
Attorneys raised a separate legal question. National security lawyer Brad Moss told CBS News that disclosing polygraph details from an official's file without consent can violate the Privacy Act of 1974. Former Army JAG officer Cody Harnish called it "a Privacy Act violation." Retired Lt. Col. Frank Rosenblatt, president of the National Institute of Military Justice, disagreed that the law was broken but questioned reliance on polygraphs, which CBS noted are not admissible as evidence in court.
Geopolitical Players
- Iran: The alleged leaks concerned U.S. Iran policy at a moment when CENTCOM's Adm. Brad Cooper has briefed Trump on military options and the Pentagon is preparing strike options for after the Nov. 3 midterms, according to multiple reports. Any compromise of planning would matter to Tehran.
- Ukraine and Russia: The alleged Ukraine disclosures concerned U.S. assistance to Kyiv, as Washington pursues talks with Moscow and has stalled the transfer of Europe-funded Patriot interceptors, as Ecker Geopolitics reported earlier.
- Allies: A leak case at the top of the Joint Staff may make partners more cautious about sharing planning details, though no allied government has commented publicly in the sources reviewed.
What It Means for the United States
Benefits and opportunities
- If the allegations are proven, the case signals that leaks of classified war information carry consequences at the highest ranks, a deterrent the Pentagon has openly sought.
- A Justice Department process would test the evidence in court, where it can be weighed independently.
Risks and dangers
- Leaks about the Iran and Ukraine wars, if confirmed, could expose U.S. planning during an active conflict.
- Analysis: Publicizing polygraph results before any charge risks Privacy Act litigation, as attorneys told CBS News, and could complicate any prosecution.
- The churn of more than 20 senior leaders under Hegseth raises questions about continuity in strategic planning on the eve of possible renewed combat with Iran.
- Prior leak firings ended without charges, which could fuel claims the process is political rather than evidentiary.
