Defense Secretary Pete Hegseth is revoking Gen. Mark Milley's personal security detail and clearance — and the former Joint Chiefs of Staff chair faces a review that could result in a rank demotion, the Pentagon announced Tuesday night.

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.
