White House communications director Anthony Scaramucci has launched a foul-mouthed attack on his most senior colleagues, using language that US television networks refused to repeat.
In an exchange with a New Yorker reporter, Mr Scaramucci ranted about chief of staff Reince Priebus and chief White House strategist Steve Bannon.
"Reince is a paranoid schizophrenic," Mr Scaramucci was quoted as saying in an expletive-filled tirade in which he accused the chief of staff of damaging information leaks.
"They're trying to resist me, but it's not going to work," he said, adding that Mr Priebus would soon resign.
Turning his sights on President Donald Trump's chief strategist, Mr Scaramucci made it very clear he believes Mr Bannon is working in the White House to serve his own interests, using particularly offensive language.
"I'm not trying to build my own brand off the strength of the president. I'm here to serve the country."
Mr Scaramucci, a millionaire New York financier, has arrived at the White House vowing to serve Mr Trump's interest and right a badly faltering administration.
But the revelations are likely to draw questions about whether his tenure at the White House will be a long one.
Mr Scaramucci did not apologise for the tirade, but said he would try to clean up his language in the future.
I sometimes use colorful language. I will refrain in this arena but not give up the passionate fight for @realDonaldTrump's agenda. #MAGA

White House spokeswoman Sarah Sanders said Mr Scaramucci "used some colourful language - I don't think he will again".
