There is a lot of blow back so far for his pick as interim AG.  A number of prominent constitutional lawyers (Republican and Dem) are making the argument that Whitaker's appointment is unconstitutional.

Lawyers are subject to the Bar association, their are a lot of lawyers saying the reason Sessions recused himself in the first place is that he didn't want to be disbarred and have that be how he was known.  AG was his dream job and he doesn't want a stained legacy of his short time there.

I think Sessions was really bad as the AG and the dems are probably happy he is out IF Mueller is protected.

The interim job should have gone down the line of succession until a Trump nominee can be confirmed.
