I don’t know what kind of game Trump is playing here. He’s never been afraid of saying you’re fired!
Trump is playing the Not-Nixon game backstabber Sessions set him up for. Mueller is currently investigating Trump for obstruction for simply for maybe, possibly ***thinking*** about firing Sessions. If Trump actually steps into the trap neither the press nor DC will rest until Trump is destroyed.
That's when he was on TV. It's a different story now. For whatever reason Trump does not fire Jeff Sessions. Thus Trump has made two mistakes.
#1 Hiring Jess Sessions and
#2 not correcting his mistake and firing him.
