Trump can’t stand Sessions.
That’s just nonsense. Trump and Sessions go back at least a decade before Trump even ran for office. Sessions asked Trump to come to congress and give them info on how badly the UN was screwing up the remodel of the UN. There is a you tube video of this event, if you can find it. Trump credits Sessions for getting him involved. Trump offered to take over the job, and said he could come in way under budget, and way ahead of schedule. They didn’t take him up on the offer.
