Donald Trump replaces Reince Priebus as White House Chief of Staff
Video report by ITV News Correspondent Emma Murphy
US President Donald Trump has replaced his Chief of Staff just a day after his newly-appointed Communications Director launched a verbal tirade against him.
Anthony Scaramucci threatened to fire the entire department in the rant during a phone call to a reporter, which included an attack on Reince Priebus and Chief Strategist Stephen Bannon.
On Friday, Mr Trump tweeted that Homeland Security Secretary John F Kelly had been appointed White House Chief of Staff, replacing Mr Priebus.
The president also thanked Mr Priebus for his "service and dedication to his country".
Speaking later, Mr Trump also hailed General Kelly as a "star" who has done an "incredible job" to date.
What did Scaramucci say?
Speaking hours after the announcement, Mr Priebus said he had offered his resignation on Thursday.
He told CNN that he thought "the president wanted to go a different direction".
Despite being the target of a long whisper campaign by Trump allies, Mr Piebus insisted he was "Team Trump".
But he agreed the White House could benefit from "a reset."
Mr Scaramucci's verbal tirade was made during a phone conversation with The New Yorker's Washington correspondent Ryan Lizza on Wednesday night.
He has been engaged in a long-running feud with Mr Priebus, who reportedly blocked him from being appointed to President Trump's senior team immediately following the election - despite him having sold off his company, SkyBridge Capital, in anticipation of such a role.
Following his eventual appointment last week, press secretary Sean Spicer - a Priebus ally - resigned in protest.
And while Mr Scaramucci and Mr Priebus have insisted publicly that they are united in support of the president, during the conversation with The New Yorker he intimated that his rival would be asked to leave.
Mr Lizza wrote in The New Yorker of his conversation with Mr Scaramucci:
Mr Lizza said at no point did Mr Scaramucci request that the conversation be off the record - but he has now tweeted lamenting his "mistake" in "trusting a reporter".
