As negotiations continue over whether Trump will sit for an interview, the New York Times obtained a lengthy list of questions Mueller and his team have prepared for the president.
"So disgraceful that the questions concerning the Russian Witch Hunt were 'leaked' to the media. No questions on Collusion," Trump wrote on Twitter. "It would seem very hard to obstruct justice for a crime that never happened!"
Mueller's investigators read the questions to Trump's lawyers who compiled them into a list, the New York Times reported on Monday. The newspaper said it obtained the document from a person outside Trump's legal team.
Trump's lawyers met with Mueller last week to discuss a possible interview with the president, according to the Wall Street Journal, which also reported on the potential queries.
Representatives for the Mueller's office declined to comment and Jay Sekulow, a lawyer for Trump, also had no comment. Reuters could not confirm the published accounts.
Savannah Law School professor Andrew Wright, who served in President Barack Obama's White House, said it was difficult to know who would have leaked the questions and why.
"It's hard for me to imagine it's coming from Mueller's team. And it's kind of a ham-handed effort if it's someone who's trying to help the president," he said.
Russia has denied interfering in the 2016 U.S. presidential election, as U.S. intelligence agencies allege, and Trump has denied there was any collusion between his campaign and Moscow.
Most of the questions relate to possible obstruction of justice, the reports said.
Manafort targets possible leaks
"What knowledge did you have of any outreach by your campaign, including by Paul Manafort, to Russia about potential assistance to the campaign?," one question asked, referring to Trump's former campaign manager, according to the Times.
Manafort faces charges in two federal courts that include conspiracy to launder money, failure to register as a foreign agent when he lobbied for the pro-Russia Ukraine government, bank fraud and tax fraud.
Late on Monday, Manafort's lawyers asked a federal judge in Virginia to hear arguments later this month on whether prosecutors in Mueller's office may have leaked classified and other secret materials about the case to the media.
On Friday, Manafort's lawyers will ask the judge to dismiss the indictment in that court on the grounds that the scope of Mueller's probe is excessive.
Mueller's list also included inquiries about Trump's firing of former FBI Director James Comey, who headed the Russia investigation before he was dismissed in May 2017, and the resignation of former national security adviser Michael Flynn, the Times reported.
Flynn has pleaded guilty to lying to the FBI during his interview as part of Mueller's probe.
