If they are injured or killed, Donald Trump will be the one person responsible — a black mark against him that time will not erase.

Early in his first administration, President Trump noted the general’s “brilliance and fortitude.” And then the president got angry.

Gen. Mark Milley, a frequent target Trump’s, will lose his security detail and face an inspector general investigation, said a senior defense official.

Retired Gen. Mark Milley's personal security detail and security clearance is being pulled by Defense Secretary Pete Hegseth, multiple senior administration officials tell Fox News.

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 asked its inspector general to review the record and behavior of Gen. Mark A. Milley, the retired chairman of the Joint Chiefs of Staff who stood up to President Trump in his first term.

Trump already stripped security details from his former secretary of state, Mike Pompeo, and a former top aide, Brian Hook. Both men face ongoing threats from Iran after Trump ordered the killing of Iranian general Qassim Soleimani, who led the Iranian Islamic Revolutionary Guard Corps’ Quds Force, during his first term.

Pete Hegseth is also reportedly considering demoting Mark Milley, with a review board set to analyze whether he took actions to "undermine the chain of command."
