Sessions was easily Trump's worst pick. His mind stopped evolving sometime shortly after I was born, and he has difficulty recognizing the difference between real threats (meth, heroin, human trafficking, terrorism...) and faux threats (marijuana, bathroom entry rules...).
I disagree with most of Trump's picks, but I completely agree With you on Sessions and all of the issues that you mentioned. He has a brain like a stone that can no longer change or absorb anything new. The stone can only erode further from here on out.
Sessions intel: He would resign if Trump wants him to. In fact, he should resign to preserve his integrity and join Comey . BTW: Comey testifies to the investigative committee Thursday.
I'm not a Doctor but I can assume that Mr. Trump can't let events go. His little weapon is the Twitter. You can't play any sport or move forward when your fixated on a sour moment. The mayor of London can affirm this.
Comey released a statement absolving Trump of applying any political pressure on him or interfering with any investigation, as expected from his previous testimony.
