“Time for the Marines to seize Langley and FBI HQ.”
I agree. Declare the CIA and FBI in insurrection and order martial law against both agencies. Set up a military court to judge the treasonous ringleaders.
Keep in mind that in the latter days of the Watergate crisis, Defense Secretary Schlesinger and Secretary of State Kissinger kept President Nixon from direct access to the military, especially the Marines, whose commandant was sympathetic to the President's plight. By that time, however, Nixon had lost most of his confidants like Haldemann and Erlichman, was depressed, and drinking heavily. It is unlikely Trump has Nixon's problems, but would Defense Secretary Mattis do what Schlesinger and Kissinger did 42 years ago, thus blocking Trump from using the military to decapitate the hostile Federal spy and law enforcement agencies?
