President Donald Trump chose Mick Mulvaney, the director of the Office of Management and Budget, to be his acting chief of staff. John Kelly, the current chief of staff, is departing the administration. Mulvaney will be Trump's third chief of staff in less than two years.
Kelly replaced Trump's first chief of staff, Reince Priebus, a former chairman of the Republican National Committee, after Trump fired him.
Trump appointed Mulvaney to the position in an acting role about a week after Vice President Mike Pence's chief of staff Nick Ayers declined Trump's offer to become chief of staff, refusing to agree to a two-year time commitment the President had requested.
Mulvaney will step down from his role as OMB director, a White House official said. Mulvaney had indicated that he was not inclined to take the position of White House chief of staff, with a source close to him instead indicating Mulvaney was interested in moving up to Treasury secretary or secretary of Commerce.
