Barr's comments are optics. Discerning anons know this already. Barr cannot say anything to prejudge the case in the public's eye. His statements presume, for public consumption, a limited scope of facts.
He has to take this stance as a neutral AG. Take another survey of the landscape once the IG comes out…and the evidence of TREASON become front and center.
Do not miss the bigger picture. If treason was committed, then EVERYTHING these people did is evidence of it…the leaks, the FISA abuse, etc…all of it….you don't need multiple charges detailing the constituent acts that make up the whole, you only need the whole. Treason is punishable by death, and these assholes conspired with foreign agents and dignitaries to overthrow the election.
Barr can't say anything that hints of this prematurely.
PATIENCE
