FBI special counsel Robert Mueller has at least four dozen questions he wants to ask President Donald Trump to learn about his ties to Russia and determine if he obstructed the Russia inquiry itself, The New York Times reported.

The questions, obtained by Times, deal primarily with the president's firings of former FBI Director James Comey and his first national security adviser, Michael Flynn, his treatment of Attorney General Jeff Sessions, and a 2016 Trump Tower meeting between campaign officials and Russians offering dirt on Hillary Clinton.

According to the Times, they also touch on Trump's businesses; any discussions with his longtime personal lawyer, Michael Cohen, about a Moscow real estate deal; whether the president knew of any attempt by his son-in-law, Jared Kushner, to set up a back channel to Russia during the transition; any contacts he had with Roger Stone, a longtime adviser who claimed to have inside information about Democratic email hackings; and what happened during Trump's 2013 trip to Moscow for the Miss Universe pageant.

According to the Times, the majority of the questions relate to possible obstruction of justice — including queries on any discussions Trump had about his attempts to fire Mueller himself, and what the president knew about possible pardon offers to Flynn.

In one question, the Times reported, Mueller asks what Trump knew about campaign aides, including the former chairman Paul Manafort, seeking assistance from Moscow. There has never been any public revelations of that kind of outreach, the Times reported.

Trump lawyer Jay Sekulow declined to comment to the Times, and a spokesman for the special counsel's office did not respond to the Times' request for comment.

Trump's lawyers have been negotiating terms of a sit-down, the Times reported — and the list of questions grew out of those negotiations, the Times reported.

In January, Trump's lawyers gave Mueller several pages of written explanations about the president's role in the matters the special counsel is investigating. His lead lawyer, John Dowd, was trying to convince Mueller he did not need to interview Trump, the Times reported.
