US Deputy Attorney General Rod Rosenstein has denied a report that he discussed invoking a constitutional clause to oust President Donald Trump.
America’s second most senior law official said the allegation was “inaccurate and factually incorrect”.
The New York Times, citing anonymous sources, also said Mr Rosenstein had suggested secretly recording Mr Trump to expose chaos in the White House.
But a source told the BBC that the comment was sarcastic.
Mr Rosenstein is reported to have made the remarks after Mr Trump fired the FBI director last year.
James Comey had been overseeing his law enforcement agency’s investigation into alleged ties between the Trump campaign and Russia. Mr Trump referred to the “Russia thing” when asked why he was removed.
Mr Trump told a rally in Missouri on Friday evening that there was a “lingering stench” about what was being exposed at the US Justice Department.
He said he would get rid of it just as his administration “had gotten rid of bad people at the FBI”.
