President Donald Trump has for the first time said he is prepared to be questioned under oath as part of an investigation into alleged Russian meddling in the 2016 US election.
He said he was “looking forward” to it, subject to the advice of his lawyers.
Investigators are assessing if the Trump campaign colluded with Russia to influence the election in his favour – a claim denied by Mr Trump and Russia.
Investigators will also determine if Mr Trump obstructed the inquiry.
The US intelligence community has already concluded that Moscow tried to sway the presidential election in favour of Mr Trump.
The president had previously said he thought an interview was “unlikely” because there had been no collusion.
He has called the Russia investigation a “witch hunt” and a “hoax”.
Speaking at the White House on Wednesday, Mr Trump maintained he was “absolutely” prepared to be questioned under oath by the top investigator.
“There’s been no collusion whatsoever, there’s no obstruction whatsoever,” he said.
The president’s lawyers have been talking to the investigation team led by justice department special counsel Robert Mueller about an interview, and the form it might take.
The questioning could happen face-to-face, in writing, or it could be a combination of both.
As to when it might happen, Mr Trump said: “Yesterday they were talking about two to three weeks.”
Asked if he thought Mr Mueller would be fair, the president replied: “We are going to find out… I hope so.”
