If this report is true, surely Sessions has been informed by the committee which would make Sessions either completely inept or complicit since he has not already terminated Rosenstein.
Now that this is alleged, members of the committee will be asked to confirm, and we’ll know the answer shortly.
Nobody is that inept.
I think there is fear in firing Rosenstein and others, Sessions doesn’t like big decisions, and so Rosenstein, Boyd, Wray, and others pretty much do what they want. Once Sessions recused himself, he should have resigned as he turned over the keys and gave them power to do virtually whatever they wanted.
