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. Mark Zaid, a prominent national security attorney who sued the administration after his own clearance was revoked by the Trump administration, confirmed in a post on X that Kendall had hired him. Zaid specializes in helping a variety of military and civilian clients maintain security clearances in the face of investigations. 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.
