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.

The Pentagon has revoked the security detail and clearance for retired general Mark Milley, a former top US military commander who has been critical of President Donald Trump. Defence Secretary Pete Hegseth directed the move as one of his first acts in office, asking officials to investigate Gen Milley's "conduct" and review his military grade.

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.
