But on another significant aspect of the investigation - whether the president tried to obstruct the inquiry itself - Mueller and his investigators understood that issues of executive privilege could complicate their pursuit of a presidential interview and did not ask for written responses on that matter, according to the letter, which was sent Friday. The president's lawyers have tried to fight against accepting a formal interview, saying Mueller can use the more than 1 million documents the legal team provided investigators to determine if Trump conspired with Russian Federation.
Trump has cited their amenable relationship as evidence that the special counsel can not be impartial during the investigation. For one, Mueller interviewed with Trump for the job of Federal Bureau of Investigation director and was unsuccessful in getting it, so he may probably be resentful of the president.
"We continue to maintain an ongoing dialogue with the office of the special counsel", Trump's lawyer Jay Sekulow told reporters.
As the Post notes, "Mueller's decision to accept at least some written responses represents a concession to Trump's legal team, which since December has resisted the special counsel's efforts to interview the president".
Mr. Trump's legal team has not seen the questions from the special counsel.

Thomas' reaction to the lack of a resolution was clear in his post: "The disrespect has been noted and will not be forgotten". As a result, Thomas will play out the final year of his contract with the Seahawks .
It's not clear how Trump got the photos or what he does with them.
Echoing a previous argument, Giuliani said he will only allow Trump to submit to an interview if Mueller promises not to catch him in a "perjury trap".
The letter was first reported by the New York Times.
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.
The White House Counsel's Office, led by attorney Emmet Flood, has been girding to fight a subpoena for Trump's testimony under oath.
And for another, Trump claimed, without any proof that Comey and Mueller are "best friends" and even more, of the "hugging and kissing" variety. You know, he's Comey's best friend.
