President Donald Trump reportedly ordered special counsel Robert Mueller to be fired, one month after he was appointed, following FBI director James Comey's dismissal, according to four sources who were briefed on the incident, The New York Times reported Thursday.

The White House counsel reportedly balked at the notion and refused to direct the Justice Department to fire Mueller, and Trump was said to have eventually backed down from the decision, according to The Times.

White House counsel Don McGahn also reportedly threatened to resign after the request, arguing that Mueller's firing would bring about consequences for the Trump administration.

Mueller is reportedly aware of the incident after interviewing current and former senior White House officials, The Times continued.

Mueller is deep into an investigation of possible collusion between Trump's 2016 presidential campaign and Russia, and whether Trump obstructed justice as the investigation picked up steam. Mueller's team has interviewed Attorney General Jeff Sessions and reportedly also questioned former FBI director James Comey last year.

On Wednesday, Trump appeared to be open to the possibility of testifying under oath to Mueller: "I am looking forward to it, actually," Trump said.
