It was Andrew Napolitano who first posited (from his sources, btw) that it was British GCHQ guys who have an office AT the NSA, who were asked by Lynch for the info. Hugely illegal.
Your list is fine until the last point. It could all be a “leaking” matched to a surveillance to create a non-reality. But importantly- Admiral Rogers visited Trump the week after the election, and Clapper, Brennan and Comey screamed bloody murder. Rogers knows and knew where all the bodies were/are buried, including this GCHQ part of the “Five Eyes” intel relationship. Rogers did the right thing, and Trump knows everything about that now.
One good question is- are the deep state people feeding him bullcrap now and calling it “intelligence” even as they try to shape our policy?
