It's my belief that Trump is genuinely angry with Jeff Sessions, and the vitriol towards him is real and NOT play-acting. When Trump is dealing with Mueller trying to cast a noose around his neck, and with that psychotic, leftist MSM decrying him daily and calling for his impeachment, it's the eighth wonder of the world that he's accomplished everything he has so far.
Jeff Sessions did Trump wrong by recusing himself from anything related to Russia and not telling the President in advance what his intentions were.
And Trump is hurting himself by blasting Sessions and others publicly - without restraint. I most certainly understand and deeply empathize with his enormous frustrations, but he is playing into the hands of his critics through his incessant, demeaning tweet rants.
I am a Trump supporter. I want to see him succeed in the spectacular way that he can truly accomplish. But his excessive pride and emotional immaturity will be his downfall if he doesn't correct his thinking and conduct.
