We know Trump doesn't think twice about firing someone. Hell, he even had a show on NBC that gave him the reputation. He's fired TONS of people he appointed, from Sessions, to Comey to Krebs, et. al.
My question? "If Trump really is displeased with Barr, why hasn't he fired him"? Is it all subterfuge? Is Barr possibly the ace in the hole? What's going on?
I think it's a little deeper than that. I get the feeling they are still trying to lure someone else out into the open.
