The Pentagon’s inspector general will review the conduct of the former chair of the Joint Chiefs of Staff, who has been a vocal critic of the president.

Defense Secretary Pete Hegseth on Tuesday revoked the security detail and security clearance for Gen. Mark Milley, according to Pentagon spokesman John Ullyot, an unprecedented move against the former top US general who became a frequent target of President Donald Trump.

Defense Secretary Pete Hegseth is pulling the security protections and clearance of retired Joint Chiefs Chairman Gen. Mark Milley.

Former Defense Secretary Mark Esper's security detail, which was provided by the Defense Department, was pulled Tuesday night, a U.S. official told CBS News.

Pete Hegseth told Milley, a critic of Trump, that he had ordered an investigation to determine whether his rank should be re-evaluated.

President Donald Trump has revoked the security detail assigned to his former Defense Secretary Mark Esper, a person familiar with the matter confirmed Wednesday, adding to the growing list of officials who have faced retribution from their onetime boss.
