Former Air Force Secretary says he'll sue Trump administration to restore his security clearance

Former Air Force Secretary Frank Kendall on Monday said he'll sue to force the Trump administration to restore his security clearance, which it revoked Friday after claiming he had disclosed sensitive information about the Qatari-gifted jet now serving as Air Force One.

Kendall, a West Point graduate who served as President Joe Biden's head of the Air Force, said on CNN Monday that he'll sue the administration, noting it has a history of retaliating against critics by stripping their clearances. “As my mother taught me years ago, you stand up to bullies,” said Kendall, who has denied disclosing classified information.

Mark Zaid, a prominent national security attorney who sued the administration after his own clearance was revoked by the Trump administration, confirmed in a post on X that Kendall had hired him. "More to come,"" Zaid wrote.

Zaid specializes in helping a variety of military and civilian clients maintain security clearances in the face of investigations.

Last year he became a target of the Trump administration’s efforts to strip security clearances from people they perceived to be enemies when he was named among 14 other people in an executive order signed by Trump. In a March 2025 executive order, Trump named former President Joe Biden and members of his family, Biden-era Deputy Attorney General Lisa Monaco, and New York state Attorney General Letitia James as being unsuitable to retain their clearances because it was “no longer in the national interest.”

In August 2025, Trump revoked the security clearances of 37 more current and former national security officials, some of whom worked on matters that have long infuriated Trump, like the intelligence community assessment that Russia interfered in the 2016 presidential election on his behalf.

Trump has tried to squelch reports of problems with the jet that Qatar gifted him last year, which he intends to use as Air Force One for the remainder of his term. His Justice Department last month subpoenaed New York Times reporters who wrote about security concerns with the jet, which lacks the advanced anti-missile technology of its predecessor. After being criticized by a federal judge for sloppy legal work, the government grudgingly withdrew the subpoenas.
