Get real, it clearly did not “have to be this way.” Sessions should have never taken the job, just as Trump has statd several times. And he’s had plenty of time and reason to resign, by now, to allow the President to appoint someone capable of controlling the rogue DOJ. Add it up and in total, Sessions is complicit in he corrupt DOJ, plain and simple.
If Trump really wanted Sessions gone, he would have already been gone - nothing happens unless Trump wants it to happen with his people.
