I sincerely wish everyone would stop focusing on Sessions - the crux is Trump and Trump alone. He and everyone else with a clue know all the various possible moves & outcomes from the current position of the pieces on the board.
Coulter accused Trump of being lazy - that's the first I've seen, since all we've heard is he's a workaholic. If he doesn't make a move, then he's lost. Yet, if he fails to take the initiative, then good riddance and bring on the next act in this farce.
At this point in time, Trump has three options: (a) support Sessions in a 4D long game; (b) fire Sessions and prepare for impeachment; (c) ready the MIC in the cause of national security.
If Trump shies away from taking direct action, then he'll lose his base and 2018. Bye bye. Tick tock the clock is sounding.
He needs a mass firing. Sessions, rosenstein, and mueller along with some others. Have the marines at the ready.
If Trump himself is compromised(a possibility seeing how corrupt the deep-state is), it’s all over but the screaming and the dying.
