Trump has publicly voiced his frustrations with Mueller and Rosenstein, who oversees Mueller's investigation, which Trump has repeatedly described as a "witch hunt." Trump has previously said that many people have advised him that he should fire Mueller.
"I think it's a disgrace what's going on. We'll see what happens," Trump said last week when asked about whether he would consider firing Mueller. "But I think it's really a sad situation when you look at what happened. And many people have said, 'You should fire him.'"
The president Wednesday again denied broadly that there was any collusion between his campaign and the Russians, which is one of the questions that Mueller's team is investigating.
"There's no collusion," Trump said, going on to dismiss the notion as a Democrat-created hoax.
Even as he sought to discredit the basis for an investigation, the president made a point to insist that his cooperation has been complete and comprehensive.
"As far as the investigation, nobody has ever been as transparent as I have. I have instructed our lawyers: Be totally transparent," Trump said. "We have given them 1.4 million pages of documents, and haven’t used – as I know of for the most part – presidential powers or privilege.
The president also expressed his hope that "we’re coming to the end" of the investigation. "We want to get the investigation over with, done with. Put it behind us," Trump said.
