If I were Barr, I wouldn’t be happy about some of his tweets either. I would privately and respectfully speak to Trump about my concerns. But as one of my CO’s once said:
“When you and your boss have a personality conflict, he has a personality, and you have a conflict...”
As an American I am not too happy with the DOJ being used by the Deep State to coup Trump and Barr has done some good but I think he is trying to protect the Deep State institutions (of which elements of the DOJ are part of) while (I assume) routing out the rogue elements - he is former CIA after all.
I just hope to hell that they have had a private discussion or two: “So tell me Bill, why is it that, in the course of the last three years, several people associated with me have been investigated, indicted, tried and convicted, while none of the conspirators in what was obviously a coup attempt have yet been charged? Justice isn’t just blind, it’s deaf and dumb as well.”
