Unless one of his advisors told @POTUS "You've got to fire Comey", for starters, you've got nothing. To the contrary, I believe they might have been doing the opposite. I believe that Barr described @POTUS best as being emotionally motivated by the pure injustice and harassment that Comey and his ilk were up to and the general hindrance that Comey and the FBI with their implementation of "Crossfire Hurricane" with the illegal spying, inserted spies and unmasking, etc. How could any reasonable person (the legal standard) find that @POTUS likely fired Comey over investigating a crime WHICH @POTUS KNEW NEVER TOOK PLACE rather than for being the treasonous rat bastid he clearly was? THIS is why no obstruction could ever be proved.
I suspect that you are a shill. Anyone who has truly waited for 60+ years since JFK who isn't gratified that the head of the DS snake all that time has been finally brought to justice and the his plans for his NWO are kaput is either ignorant or a shill.
