Trump appointed Sessions cuz Trump felt he was going to need someone to really, REALLY have his back:
Sessions was the very first Senator to stick his neck out and support Trump.
Sessions really did seem like the right guy for the job, that he would GO AFTER Trump enemies with an unslakeable thirst for justice.
Yet he’s too timid to take even the first little, bitty sip.
Trump declines to fire Sessions “cuz it would seem like Trump is LIKE NIXON”.
So Trump is STUCK with this Do Nothing.
He’s actually supporting them. Sessions praises the ‘deep state’ at every opportunity.
