Former President Biden’s preemptive pardon for retired Gen. Mark Milley, the former chair of the Joint Chiefs of Staff, will give the retired military official a shield against any action that President Trump might take against him amid their highly public feud.

A portrait of retired Gen. Mark Milley, a target of President Donald Trump's wrath, disappeared from a Pentagon hallway hours after the inauguration.

"My family and I are deeply grateful for the President's action today," Milley said in a statement to USA Today provided by a spokesperson.

Gen. Mark Milley, the now-retired former chairman of the Joint Chiefs of Staff, commented on the pardon he received in Biden's final hours in office.

The Pentagon on Monday removed the portrait of Mark Milley, the retired Army general and former chairman of the Joint Chiefs of Staff, according to two Reuters witnesses, in a move that happened within two hours of President Donald Trump's inauguration.
