Flynn is essential to the Personal Trump Agenda. Bye Bye Ryan, Romney Pelosi, Biden, Brennan, Clapper and Clinton and the Obamas.
Flynn knows where all the bodies are buried, but I don’t think would qualify for a top security clearance because of the pardon. He would first need to be fully exonerated by a court.
I am also not sure the senate would approve him for any high ranking role, we have too many RINO’s.
It would be a hoot though to see Flynn work his magic on the Rat moles that caused him so much distress, especially that scum bucket Sullivan.
