US President willing to be questioned 'under oath' in Russia probe

Trump confirmed that his lawyers are in discussion with Mueller, who is leading the investigation into collusion between the US president's election campaign and Russia in the 2016 election, and also into allegations that Trump tried to obstruct his probe.

"I would love to do it," Trump told reporters in the White House when asked about testifying.

"I would like to do it as soon as possible... subject to my lawyers and all of that."

"I would do it under oath, absolutely," he added.

Asked when an interview could happen, Trump replied that he didn't know exactly.

"Yesterday, they were talking about two or three weeks," he said.

It was the first time the Trump said directly that he president would cooperate with Mueller, whose investigation he has repeatedly dismissed as being based on "fake news."

"There has been no collusion whatsoever. There is no obstruction whatsoever," he said Wednesday.

Executive privilege

But any interview of a US president in an investigation is fraught with issues of executive privilege -- how much and in what context the US leader can be forced to disclose information.

In Trump's case, it also raises deep concerns that his shoot-from-the-hip outspokenness could jeopardize his own legal position.

Special counsel Mueller is believed to be focusing on whether Trump illegally interfered with the Russia investigation, particularly when he fired FBI director James Comey last year.

Mueller, himself a former FBI director, is also examining the extent of communications between Russians and Trump campaign officials, including a meeting in June 2016 between Trump's son Donald Trump Jr, his son-in-law Jared Kushner, and a Russian lawyer who had allegedly offered them dirt on Trump's election rival, Democrat Hillary Clinton.

He has already issued indictments for four people from the campaign, securing guilty pleas from two: former national security advisor Michael Flynn, and former foreign policy advisor George Papadopoulos, both for making false statements.

Circling the White House

Mueller's investigators have been edging steadily closer to the White House, last week interviewing Attorney General Jeff Sessions -- who was a top Trump campaign official and had three meetings in 2016 with Russia's US ambassador, Sergei Kislyak.

He has interviewed Comey and other former officials, and is reportedly going to interview former White House Strategist Steve Bannon in the coming days.

Ty Cobb, one of Trump's lawyers, has repeatedly said since last year that the president is willing to testify to Mueller's investigation, and wants Mueller to wind up the case as early as possible.

Trump "wants to put the matter to rest," Cobb told CBS News last week.

The form of an Mueller interview with the president still needs to be negotiated -- whether it is face-to-face, or in writing, or a mix.

Trump told reporters Wednesday he would listen to his lawyers' advice on how to proceed. Asked if he thought Mueller would be fair, he replied:

"We are going to find out... I hope so."

But the case might not be cleared easily. Trump's repeated tweets attacking Comey and the FBI have added to suspicions that he has sought to stymie the Mueller investigation.

On Tuesday the Washington Post reported that last year Trump pressed Comey's temporary replacement, FBI deputy director and Comey loyalist Andrew McCabe, to tell him who he voted for in the 2016 election.

Since then Trump has pressured the current FBI chief, Christopher Wray, to fire McCabe.

White House spokeswoman Sarah Sanders dismissed Wednesday the Post report on the Trump-McCabe exchange by saying she doubts "any person in America" cares about it.

That sparked a mass rebuttal on Twitter by Trump critics declaring they do care, using the hashtag "#onewhodoes.
