EPA head—fired, HUD head—fired, Ag dept. head—fired, Attorney General Lynch the Liar—fired, all head attorneys in every federal district—fired (just as BJ Bill Clinton did). Have the secret service round them all up on day one, bring them into the White House parking lot and fire all of them at one time.
While they are there, have all their computers seized and preserved for evidence against them. Lastly, let them walk home.
The department heads aren’t the problem. They can go on day one because they are “political appointees!” The problem is all the “termites” that are covered under Civil Service. To get at them, he will first have to attack the judiciary, or it will be an uphill battle!
