WASHINGTON (AP) — Defense Secretary Pete Hegseth is pulling the security protections and clearance of retired Joint Chiefs chairman Gen. Mark Milley, and has ordered the Pentagon’s inspector general to review Milley’s actions while serving as the nation’s top uniformed officer to determine if a demotion is warranted, two defense officials confirmed late Tuesday.

The inspector general review will include “an inquiry into the facts and circumstances surrounding Gen Milley’s conduct so that the Secretary may determine whether it is appropriate to reopen his military grade review determination,” said Pentagon spokesman John Ullyot.

“The Secretary informed General Milley today that he is revoking the authorization for his security detail and suspending his security clearance as well,” he said.

Milley served as chairman during President Donald Trump’s first term in office. While the relationship initially went well, it soured deeply and fast, as Milley tried to advise and contain the president on a host of issues.

He pushed back on the president’s interest in using force domestically to quell protestors after the death of George Floyd, and was at the center of a controversy in 2021 when he made independent calls to his Chinese counterpart. Trump called the calls an act of treason, but at the time Milley said the calls were routine and part of the scope of his job.

Milley in his final days as chairman after Trump had left office was equally outspoken about his former boss. He said at his official retirement ceremony “ we don’t take an oath to a king or a queen or to a tyrant or a dictator. And we don’t take an oath to a wannabe dictator.”

“We don’t take an oath to an individual. We take an oath to the Constitution, and we take an oath to the idea that is America, and we’re willing to die to protect it,” he said at the time.

Hegseth’s chief of staff Joe Kasper said that the decision to strip Milley of his clearance and detail was taken because “undermining the chain of command is corrosive to our national security, and restoring accountability is a priority for the Defense Department under President Trump’s leadership.”

The moves, which were first reported by Fox News, may also include taking down Milley’s Army chief of staff portrait. Milley’s chairman portrait was stripped from the wall just hours after Trump was sworn in. The portraits were both paid for by a donation from the Association of the United States Army, not taxpayer dollars, and were a gift to Milley honoring his service.
