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.

The Pentagon did not immediately respond to a question about why the portrait was removed days after its unveiling.

Trump had deep resentment toward Milley, and once called him “slow moving and thinking” and a “moron.” Hours earlier, former President Joe Biden had issued a preemptive pardon to Milley and others Trump had targeted for potential retaliation.
