At some point, there was enough there to bring Rosenstein into a grand jury room (willing to wear a wire into the White House would get you serious charges). I think the WH lined up the deal...you get the Mueller report to end in six months, with no additional heat for the President, and we let you retire and slide away with no charges. He’s kept his end of the deal, and I can’t see him dragged into a fresh mess now.
May well be the case, and I don't have a huge problem with that.
My issue is that nobody seems to be being held accountable.
Next thing we know, we'll have an impeached president, and the Huber, Horowitz, Barr & Durham crew will be saying, 'Damn -- just when we were about to bring some of these players to justice!"
Any day, now! Maybe next month...
