Mulvaney joined a growing list of Trump administration officials who are leaving following the violent riot at the Capitol on Wednesday.

Mulvaney said he called Secretary of State Mike Pompeo Wednesday night to tell him that he was resigning. He served as acting White House chief of staff from January 2019 until March 2020. Before that, he was director of the Office of Management and Budget.

“I can’t do it. I can’t stay,” Mick Mulvaney told CNBC, which was first to report the resignation. “Those who choose to stay, and I have talked with some of them, are choosing to stay because they’re worried the president might put someone worse in.”
