I used to have a clearance above Top Secret as well. Mine was a compartmentalized clearance with strictly a need to know and I only knew a little about my own program.
I read that CONGRESS can’t even read some of the emails. Congressmen on the committee overseeing these agencies can’t read it, but it was on a home brew server in her bathroom for China, Russia, North Korea...
Except none of us knew what anyone else was doing. I mean that my best office mate had no idea of what I was working on. No idea whatsoever, and I hadn't a clue about his work.
All classified information is "need to know." I can almost guarantee that the staffers who were cutting and pasting from the classified server would not pass "need to know" scrutiny. They may not even have had the clearance.
I suspect the evidence will be damning. I also suspect Hillary will throw her staff under the bus. So, which ones of those will be loyal enough to go to prison for her?
