Aug. 7 (UPI) — The Defense Department on Friday revoked Frank Kendall’s access to classified information, accusing the former secretary of the Air Force of leaking sensitive information to the press.

Pentagon spokesman Sean Parnell said Frank was the source who told reporters that President Donald Trump’s new Qatari-gifted jet lacked certain security features.

Parnell said the Defense Department revoked Kendall’s “eligibility for access to classified information and his ability to hold any sensitive position.”

“This action follows his unauthorized disclosure of classified information regarding Air Force One’s capabilities to a media outlet,” the spokesman wrote on X. “Safeguarding classified information is a non-negotiable duty.

“Those who violate that trust forfeit the privilege of access and any role requiring it.”

Kendall, a lawyer and engineer, served as U.S. secretary of the Air Force from 2021 to 2025 under the Biden administration.

When asked about the new Qatari jet, Kendall told CNN it would take three to four years to get the plane on-par with the expectations of an aircraft serving as Air Force One.

The New York Times first reported that Trump’s new Air Force One, a Boeing 747-8, lacked advanced security features such as antimissile capabilities.

The plane was a $400 million gift from Qatar, but despite retrofitting, did not reach the level of safety required of the U.S. president’s main aircraft, The Times reported.

Trump denied the report and called for the prosecution of leakers, though days later he said the plane would be taken out of commission to be “maxed out” — tacitly admitting it wasn’t fully upgraded already.

The Trump administration subpoenaed four Times journalists over the incident.
