This was Barry O's exec order covering classified info. Look at subsections (1) and (2) of section 4.3 -
These officials shall keep the number of these programs at an absolute minimum, and shall establish them only when the program is required by statute or upon a specific finding that:
(1) the vulnerability of, or threat to, specific information is exceptional; and
(2) the normal criteria for determining eligibility for access applicable to information classified at the same level are not deemed sufficient to protect the information from unauthorized disclosure.
These subsections describes the level of information these traitor pieces of shit were regularly selling to enemies, including nations like Pakistan who work directly with actual terrorists (not fake terrorists). This type of information is so incredibly sensitive that it's restricted even among the most trusted personnel at the very top. These traitors were just selling this shit straight up, probably since 2004 when the Awans came to work in the House.
(note that prior executive orders used similar language like EXCEPTIONAL VULNERABILITY)
At the same time, among other things, these people were also selling nuclear material like plutonium and uranium to enemies. That's what Lambert at TLI got in trouble for.
Add it up. Department of Energy has a shit ton of special access program/very high level shit and is considered a super scary spook infested agency for a reason. Info on nuclear weapons etc is very very dangerous. A ton of people were (are?) compromised in relation to DOE, NNSA, some military, whatever. Across the board. Not to mention all the agencies who protected the traitors.
It's impossible to put all this together as an outsider in a nice little package, but it appears they were selling info on nukes and nuke weapons to literal terrorists maybe giving them the ability to dirty bomb our asses.
In the end, they'll probably hide most of the really serious shit, but it is truly up to the we the people to take action. They'll just hide everything with classification, maintaining deliberate complexity, disinformation, media spin, you name it. They'll even keep the trials/pleas hidden most likely. Look at even comey changing the fucking standard from gross negligence (legal concept) to "extremely careless" in public to get hillary off on charges that were nothing–the pathetic 10 years jailtime or fine or whatever for mishandling classified info. She even escaped that and it was TREASON SELLING TO FUCKING LITERAL TERRORISTS. Then you had the FISA bullshit and coup attempt. All part of the coverup. They've barely revealed any of that to the public, too, and that's just the tip of the tip of the iceberg of all this.
We the people need to recognize how they massively, MASSIVELY, completely sold us the fuck out in the biggest way. Treason across the board.
