Former Air Force Secretary Frank Kendall has security clearance revoked over Air Force One disclosure

The U.S. Department of War has revoked former Air Force Secretary Frank Kendall’s eligibility to access classified information over what the department says was an unauthorized disclosure involving Air Force One’s capabilities.

Pentagon spokesperson Sean Parnell announced the move Friday on X, saying it took effect immediately and also bars Kendall from holding any sensitive position.

"Effective immediately, the Department of War has REVOKED former Secretary of the Air Force Frank 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. Safeguarding classified information is a non-negotiable duty. Those who violate that trust forfeit the privilege of access and any role requiring it."

Parnell did not identify the media outlet or specify which information Kendall allegedly disclosed.

The move comes days after The Wall Street Journal published a report comparing the capabilities of the Qatari-donated Boeing 747-8, now used as a presidential aircraft, with the older Air Force One jets. Kendall was among the former officials quoted in the report.

The Journal reported that the newer aircraft lacks some capabilities available on the older VC-25A jets, including midair refueling and hardening against a nuclear blast. The report also detailed differences involving defensive systems, air stairs, baggage handling and food storage.

Kendall also discussed the aircraft publicly in other recent reports. Earlier in July, he told The Wall Street Journal that fully retrofitting a 747 with the defensive capabilities needed to protect the president should take three to four years.

Kendall served as secretary of the Air Force under former President Joe Biden from 2021 until January 2025. He previously served as the Pentagon’s undersecretary of defense for acquisition, technology and logistics during the Obama administration.

Kendall also has a longstanding connection to the Air Force One modernization program. In 2015, while serving as the Pentagon’s acquisition chief, Kendall coordinated with then-Air Force Secretary Deborah Lee James on the decision to use the Boeing 747-8 platform for the next generation of presidential aircraft.

A representative for Kendall did not immediately respond to Fox News Digital's request for comment.
