I recommend you take the time (about 53 minutes) to watch this video in which William Binney explains the US data collection network. It's a real eye-opener (at least it was for me):
By the way, while watching this video it occurred to me that this is where all the "leaks" about Trump are coming from - the so-called "intelligence community". The agencies and groups listed by Binney have access to EVERYTHING, and that allows them to spy on anyone, high and low.
And if true, that confirms what Dr. Paul Craig Roberts said - they're all part of a treasonous conspiracy to take down the president and destroy our government.
