Former Acting White House Chief of Staff Mick Mulvaney has resigned from his current role as special envoy to Northern Ireland, citing the breach on the U.S. Capitol building on Wednesday.
Mulvaney, who held the position of Acting White House Chief of Staff for a little more than a year, issued his resignation by phone to U.S. Secretary of State Mike Pompeo.
"I can't stay here," Mulvaney told news outlet CNBC. "Not after yesterday.You can't look at that yesterday and think I want to be a part of that in any way, shape, or form."
Melania Trump's chief of staff, Stephanie Grisham; White House Deputy Press Secretary Sarah Matthews; White House Social Secretary Rickie Niceta; National Security Council's senior director for Russian and European Affairs Ryan Tully; and Deputy National Security Adviser Matt Pottinger also have resigned.
