Because he insists that the Mueller investigation is a witch hunt AND his appointee for Attorney General William Barr says that Mueller would not be involved in a witch hunt. So Barr has already contradicted his boss-to-be. No one does that and survives! Barr said Mueller would not do that. How can you-know=hoo tolerate a guy like that?
Also William Barr said he would not be bullied into doing anything wrong. Well that's precisely why youknowwho picked him. To do his bidding. To roll over and obey without question. So unless Barr was LYING during his testimony and will absolutely enjoy being bullied to do the wrong thing then he is the wrong appointee for u no hoo. Ya know?
