I know this isn't something new but I'll admit that maybe 15-18 years ago I had heard of this from the owner of a small tech company I was contracted at. He had worked on missile propulsion systems under some NSA work group. He had said back then that all communications, ALL, 100%, goes through the great "FW" of USA and all data is captured and saved digitally.
Anyway, the recent scandals and such going on, sort of does prove this to be true. Even to the extreme of top level congress / government staff, down to you and me.

Again nothing new but still makes me cringe knowing we have a bit of confirmation as of late.
