Trump has the AG (it seems) but I still don't trust the the FBI, the CIA, Mitch McConnell, most of the government in general including many of Trumps own staff, and certainly not the GOP that fought him every step of the way. Assuming he is in a position that is unassailable seems premature at best.
Your worries run too deep. The FBI and CIA have been purged. Remember this is a military operation and not a political one. We are not above going the martial law route shall it be necessary and that word is out. Resist or perish.
