News of Mueller's latest plan, first reported by The Washington Post on Tuesday, comes days after his questioning of Attorney General Jeff Sessions, the first Trump Cabinet member to be interviewed in the protracted investigation. It also came on the heels of further comments from Trump's White House team about the Mueller probe earlier Thursday as negotiations continue for the presidential interview.
What's more, he would "absolutely" do it under oath.
White House counsel Ty Cobb declined to comment on the matter, the newspaper said. Russian Federation has denied it. Trump has denied collusion with Russian Federation and calls the probe a witch hunt.
The US intelligence community has already concluded that Moscow tried to sway the presidential election in favour of Trump, though Russian Federation denies that.
If Trump is questioned, he'll likely be grilled about his firing of FBI Director James Comey and Comey's claim that Trump asked him to stop investigating former National Security Adviser Michael Flynn.
"There has been no collusion whatsoever, there has been no obstruction whatsoever", he said.
Any interview of a USA president in an investigation is fraught with issues of executive privilege - how much and in what context the U.S. leader can be forced to disclose information.
The special counsel investigation led by Mueller, a former FBI director, has seized headlines this week as a flurry of developments became public.
President Donald Trump is apparently "looking forward" to speak to special counsel Robert Mueller regarding the ongoing investigation into alleged Russian interference in the 2016 presidential election.
Two separate investigations into alleged Russian meddling in the US election, which have been dubbed a "witch hunt" by Trump, are now conducted by the US Congress and by FBI Special Prosecutor Robert Mueller.
But Trump expressed concern about the Federal Bureau of Investigation and 50,000 missing text messages of two former Mueller probe members. He has been seeking an interview with Trump, but White House officials had not previously confirmed that the president would grant one.
"Certainly I'll see what happens", he said during a news conference this month.
