Trump has often criticized his former top general, whose portrait was taken down at the Pentagon just after the new administration took office.

"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.

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.
