WASHINGTON (REUTERS) - United States Special Counsel Robert Mueller will accept written answers from President Donald Trump on whether his campaign conspired with Russia to interfere in the 2016 US election, but is not ruling out a follow-up interview on that issue, a person familiar with the matter said on Tuesday (Sept 4).
Mr Mueller's offer to accept written responses from Mr Trump on questions about possible collusion was contained in a letter that Mr Trump's lawyers received last Friday, the person said.
The letter was first reported by the New York Times.
Mr Trump's legal team and Mr Mueller's investigators have been negotiating for months over whether the President will be formally interviewed in the probe.
After receiving the written responses, Mr Mueller's investigators would decide on a next step, which could include an interview with Mr Trump, the person said.
Another area of interest to Mr Mueller's office is whether Mr Trump tried to obstruct the investigation, but it was not clear how any possible questions on that subject might be handled.
A spokesman for Mr Mueller's office declined to comment.
Mr Rudy Giuliani, one of Mr Trump's lawyers, did not immediately respond to a request for comment.
US intelligence agencies have concluded that Russia interfered in the 2016 presidential race, seeking to tilt the vote in Mr Trump's favour.
Russia has denied interfering in the election. Mr Trump has said there was no collusion and has called the Mr Mueller probe a "witch hunt."
