How many people at DOJ do you suppose need to be replaced?
A new AG wont be able to do a thing with the current crew.
The DOJ regularly uses task forces made up of selected internal people and outsiders hired to aid in prosecution. Many times those outsiders get permanent DOJ jobs as they become open. This can certainly be done for prosecution of corrupt political actors.
IF it is LESS than 200, I would be surprised.
This has gone on too long & has grown too DEEP.
