Anthony Scaramucci was removed as Donald Trump’s communications director on Monday, ending a tumultuous eleven days in the role.
The president made the decision following a request from John Kelly, the new White House chief of staff, who insiders said wanted to make clear he was in charge.
“A great day at the White House!” Mr Trump tweeted.
In a statement, the White House said: “Mr Scaramucci felt it was best to give Chief of Staff John Kelly a clean slate and the ability to build his own team. We wish him all the best.”
Mr Kelly, the widely-respected former retired US Marine Corps general and former commander of United States Southern Command, was sworn in as chief of staff on Monday.
The speed with which he apparently brought about the removal of Mr Scaramucci suggested he was keen to assert order quickly.
The brash, New York financier was widely criticised for unleashing a foul-mouthed rant against both Mr Priebus and Steve Bannon, Mr Trump’s chief strategist.
During an interview with a New Yorker journalist, Mr Scaramucci threatened to fire the entire White House communications team over the alleged leak of a dinner he attended at the White House.
Sarah Huckabee Sanders, White House press secretary, has said the president felt Mr Scaramucci’s comments quoted in the New Yorker article were “inappropriate”. She said his removal was a “mutual” decision and that the president had full faith in Mr Kelly.:
What matters to us is not who is employed in the White House but who is employed in the rest of the country. We are going to continue to focus on creating jobs.
