Chief of Staff John Kelly to retire at the end of the year
US President Donald Trump has named Mick Mulvaney, the director of the office of management and budget, as acting White House chief of staff.
Mr Mulvaney, 51, replaces General John Kelly, who is leaving by the end of the year.
In a tweet, Mr Trump described Mr Kelly as a "great patriot", who had served the country with distinction.
But earlier this year, General Kelly was forced to deny he had called Mr Trump an "idiot".
Trump never really left his tv show. He still fires someone pretty much every week!
