Trump doesn't like the questions Mueller wants to ask.
Mueller gives Trump's legal team questions for potential interview: reportIt was after his legal team received the questions that Trump launched into a series of tweets, in which he denied that his campaign coordinated with Moscow during the 2016 election and lambasted Mueller's investigation as unnecessary.
In one Saturday night tweet, Trump asserted that Mueller's investigation should never have been opened in the first place, because there was "no collusion" and "no crime."
That tweet came hours after John Dowd, one of the president's lawyers, called on Deputy Attorney General Rod Rosenstein, who oversees the Russia investigation, to shutter the probe.
The statement from Dowd was unusual for an attorney who has repeatedly insisted that Trump and the White House cooperate with Mueller's investigation in hopes that it would come to a natural end.
