Have Jeff Sessions switch Cabinet positions with the Secretary of Homeland Security Kirstjen Nielsen.
Both are already Senate confirmed, so there is no chance for Senators to obstruct. Nielsen has no ties to the campaign, served in the Bush administration, and received numerous government contracts under the Obama administration.
If Nielsen steps in at Justice, she will not be under any recusal, and thus will effectively strip Rosenstein of his oversight responsibility for the Mueller investigation, pushing Rosenstein back down to Deputy AG status. Then she can decide if she wants to keep him in her department staff altogether.
Nielsen can then begin to rein in Mueller, stop approving abusive witch hunt raids, and pressure Mueller towards a deadline.

Interesting proposal, but can she be trusted?
