US President Donald Trump has decided to remove Anthony Scaramucci from his job as communications director after just 10 days.
He tweeted that it was "a great day at the White House!".

"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," the White House said in a statement.
Hours earlier, Mr Trump tweeted that there was "no "chaos" at the White House.

Mr Scaramucci, a wealthy New York financier, caused a commotion in Washington last week after describing then White House chief of staff Reince Priebus as a "paranoid schizophrenic" to a journalist from The New Yorker magazine.
Referring to the Trump administration's chief strategist, he said: "I'm not Steve Bannon, I'm not trying to suck my own c***."
New White House press secretary Sarah Huckabee Sanders told reporters on Monday that President Trump felt Mr Scaramucci's comments were "inappropriate for a person in that position".
She added that Mr Trump did not want to "burden General Kelly with that line of succession".
Regarding the new chief of staff, she said General Kelly had "the full authority to operate within the White House and all staff will report to him".
Mr Trump tweeted on Monday evening: "A great day at the White House".
Mr Scaramucci's arrival in the West Wing on July 21st coincided with the resignation of press secretary Sean Spicer.
Mr Spicer had "vehemently disagreed" with the appointment of Mr Scaramucci, telling the President it was "a major mistake", the New York Times reported.
Mr Priebus was removed by President Trump late last week.
It has not been an easy period for Mr Scaramucci.
US media has reported that his wife filed for divorce while she was nine months pregnant, and that he congratulated her by text when their second son was born last week.
