All the U.S. Attorneys eventually resign when the administration changes.
...I predict that they will all be fired and loose their retirement benefits and then prosecuted.
IIRC, Clinton requested the resignations of all US attorneys. This was fine with the legacy media.
Bush 2 only requested a few resignations, after which he got attacked by the legacy media for being political.
I certainly hope that Trump requests the resignation of every possible Biden nominated person including all US attorneys.
