I personally think that Sessions was Trump’s third choice.
#1 was likely Rudy. He has battled health problems in recent years, and there are nagging, persistent rumors of a sex scandal skeleton in his closet which the media would no doubt dig-up and parade around like it was the top story of all time.
#2 was probably Chris Christie, who shot himself in both feet and his substantial arse by dragging lobbyists into the transition and forcing Trump to fire him.
Trump should have selected Larry Klayman but he needed to pay Sessions off for the loyal campaign support. Now he’s stuck with Jeff til at least after the midterms. If we pick up enough senate seats he might have enough political capital to dump him. Otherwise IMO Trump is stuck with Sessions for the first term.
That could very well be true.
