President Trump on Monday attacked Robert Mueller's credibility.

 President Trump on Monday attacked special counsel Robert Mueller's credibility in anticipation of the final report for the Russia investigation. Trump tweeted: "When Mueller does his final report, will he be covering all of his conflicts of interest in a preamble, will he be recommending action on all of the crimes of many kinds from those 'on the other side'(whatever happened to Podesta?), and will he be putting in statements from hundreds of people closely involved with my campaign who never met, saw or spoke to a Russian during this period?"  "So many campaign workers, people inside from the beginning, ask me why they have not been called (they want to be). There was NO Collusion & Mueller knows it!" he continued. Legal expert Alan Dershowitz has predicted that the report produced by Mueller "is going to be devastating to the president."
The retired Harvard Law professor and frequent Trump defender made this comment on ABC News' "This Week" Sunday, adding, in part: "I know that the president's team is already working on a response to the report. And so at some point when the report is made public...it will be made public probably with a response alongside. The president will say, 'look, it's political. There's their account and there's our account,' and then the American public will have to judge their credibility." 
"When I say devastating, I mean it's going to paint a picture that's going to be politically very devastating. I still don't think it's going to make a criminal case because collusion is not criminal," Dershowitz later clarified.
The discussion took place less than a week after attorneys for Trump confirmed that he recently submitted written answers to Mueller's team.
