Maybe Trump will have to order the US Marshals to go into the DOJ and FBI and take everything by force.
I would bet reasonable odds that this is how things go after the bureaucrats refuse to comply with legal orders, and some overt acts of sedition come to light.
Wray, Rosenstein, and Mueller have to go, along with a bunch of their supporters and backers. They aren't going leave voluntarily or peacefully.
The DOJ, FBI, and CIA need to be fumigated.
