Elon Musk is giving what he says is the explanation behind the mysterious black eye he had during a recent visit to the White House meant to address the end of his formal government duties under President Donald Trump.

The soon-to-be-former head of DOGE appeared with a purplish bruise at a press conference alongside the president Friday.

Elon Musk attributed his bruised appearance at a White House news conference to his son. “I said, ‘Go ahead, punch me in the face.’ And he did.”
