I say Sessions was a rat, a swamp rat. I disagree that he had to recuse himself. Just too damn convenient, and worst case, he should have not taken the position knowing it could come to that, or he should have resigned. And just maybe, he told Trump not to worry, for he would not let any shinanigans happen under his watch and turned around and did.
I understand Trump's mindset. I am not keen on betrayal either.
