The problem is that there doesn’t seem to be any legal controlling authority and Brennan, Mueller, Clapper, Comey are all immune, by what reason I am not sure, perhaps our AG could weigh in? Oh wait, never mind.
It has occurred to me that Trump’s intelligence agencies have probably obtained LEGAL FISA warrants to spy on Mueller, Brennan, Clapper, et al and that they are privy to everything they are doing and are deliberately giving them enough rope to hang themselves a thousand times over, and the reams of evidence will be made public when the time comes so that nobody can dispute they deserve to hang.
