The response left unresolved the issue of an in-person interview and questions regarding Trump's time in office, the source added.
The Times cited "two people briefed on" a letter 's office sent to 's lawyers. Mueller also said he would be willing to accept answers in written form, though he did ask for the possibility of a follow-up in-person interview.
Mueller's investigators and Trump's legal team have engaged in a monthslong back-and-forth about whether Trump will sit down for an interview.
Rudy Giuliani and Jay Sekulow, the president's personal attorneys, declined comment, as did a representative for the special counsel's office, according to The Washington Post. On Tuesday, the President called the Mueller investigation "illegal" in an interview with the Daily Caller.
Trump's lawyers have tried to put off a formal interview; they have repeatedly said that to determine whether the Trump campaign conspired with Russia's election interference, Mueller can find the answers in the interviews that his investigators have conducted with witnesses, including senior White House aides and administration officials, and more than 1.4 million documents turned over by the White House.

Giuliani, who like the president has repeatedly described the Russian Federation probe as a "witch hunt", told journalist Jeffrey Toobin that Trump's original legal team had struck a deal with Mueller about his expected final report that would allow the White House to "object to the public disclosure of information that might be covered by executive privilege".
Following the "kissing" comments, the President went off on a familiar diatribe about the supposed illegitimacy of Mueller's investigation, which has already resulted in almost 40 indictments against Trump associates and Russians. Trump's team hasn't responded to the latest Mueller proposal. That's an effort that could lead to a Supreme Court challenge by the White House.
The move by Mueller comes after he has issued two lengthy indictments detailing Russian efforts to interfere in the presidential campaign.
Mueller so far has not requested to ask any questions about obstruction, but included a line in his message to Trump's attorneys that he may want to ask questions about obstruction at some point in the future. You know, he's Comey's best friend.
