It doesn’t really matter at this point in the game(coup). Mueller is going to issue a ‘report’ to congress. A long laundry list of crimes and obstruction of justice in order to give a fig leaf to the rinos and neverTrumpers in the Repuki party to pull that impeachment lever. He will and they will.
If Mueller had anything to “report” it would have leaked all over the place long ago.
At that exact moment Trump needs to declassify EVERYTHING about the rat bastard crimes, fire the AG and deputy AG and clean house.
