The Department of War on August 8, 2026, revoked the security clearance of former Air Force Secretary Frank Kendall, barring him from accessing classified information or holding any sensitive position. The action follows an allegation that Kendall disclosed classified details about Air Force One’s capabilities to a news outlet, though the Pentagon did not specify which outlet or what information was shared.
Pentagon spokesman Sean Parnell announced the revocation in a post on X, stating that Kendall’s eligibility for classified access was terminated immediately. Parnell emphasized the move was in response to an unauthorized disclosure of sensitive information. "Safeguarding classified information is a non-negotiable duty," Parnell wrote. "Those who violate that trust forfeit the privilege of access and any role requiring it."
Kendall, who served as Air Force secretary under the Biden administration from July 2021 to January 2025, denied the allegation. In statements to The Associated Press (AP), he called the revocation "completely mystifying" and said he had never knowingly shared classified information. "I’ve always been extremely careful to not say anything classified, and as far as I know I have not," Kendall told AP. "No one has said anything to me about what I’m asserted to have revealed and I can’t imagine what it could be."
Kendall added that he had publicly criticized the Trump administration since leaving office and stood by his willingness to speak with the press. He told CNN he had been "comfortable being on the record with reporters" about the Qatari-gifted jet used as Air Force One, asserting he had not disclosed anything classified.
The Pentagon’s decision comes amid heightened scrutiny of the $400 million Qatari jet, which replaced the older Air Force One fleet. Reports by The New York Times in July highlighted concerns about the new aircraft’s security features, including the absence of certain antimissile protections present on the older planes. Two former Air Force officials told the Times they were surprised the jet had been used for an overseas trip to Turkey, citing elevated security risks in the region.
Kendall was quoted by the Times in July as saying the retrofit process had been rushed, leading to missing security, communications, and support modifications. "Time didn’t permit all the normal Air Force One modifications, so some mix of security, communications and support is missing," he said. "With the Iran situation, this could be of concern. Frankly, I’m surprised to see this plane used outside the U.S."
The Pentagon did not provide further details about the alleged disclosure or confirm whether Kendall would face legal consequences. The revocation follows a July 2026 video statement by Defense Secretary Pete Hegseth, who pledged a crackdown on unauthorized disclosures. President Donald Trump has previously characterized leaks as "treasonous."
Kendall’s clearance was revoked under the authority of the Department of War, which oversees military and defense operations. His removal from sensitive roles reflects a broader effort by the current administration to tighten controls on classified information, particularly regarding Air Force One and related defense assets.
The Pentagon’s action does not preclude Kendall from speaking publicly about non-classified matters, though his ability to engage with defense-related topics is now significantly restricted. His case underscores ongoing tensions between government transparency efforts and the enforcement of secrecy protocols in national security matters.
