Bernstein: Dump helped Russia destablize the US

He thinks the Mueller report will support this:

"This is about the most serious counterintelligence people we have in the U.S. government saying, ‘Oh, my God, the president’s words and actions lead us to conclude that somehow he has become a witting, unwitting, or half-witting pawn, certainly in some regards, to Vladimir Putin.' […] From a point of view of strength… rather, he has done what appears to be Putin’s goals. He has helped Putin destabilize the United States and interfere in the election, no matter whether it was purposeful or not. […] And that is part of what the draft of Mueller’s report, I’m told, is to be about. We know there has been collusion by [former national security adviser Michael] Flynn. We know there has been collusion of some sort by [Trump’s former campaign chairman Paul] Manafort. The question is, yes, what did the president know and when did he know it?"
