Highly classified Hillary Clinton emails that the intelligence community and State Department recently deemed too damaging to national security to release contain “operational intelligence” – and their presence on the unsecure, personal email system jeopardized “sources, methods and lives,” a U.S. government official who has reviewed the documents.
The official emphasized that the “TOP SECRET” documents were sent over an extended period of time -- from shortly after the server's 2009 installation until early 2013 when Clinton stepped down as secretary of state.
"Everybody who has a security clearance has an individual obligation to protect the information," said national security attorney Edward MacMahon Jr., who represented former CIA officer Jeffrey Sterling in the high-profile leak investigation regarding a New York Times reporter. "Just because somebody sends it to you … you can't just turn a blind eye and pretend it never happened and pretend it's unclassified information."
Clinton was pressed in the same ABC interview on her signed 2009 non-disclosure agreement which acknowledged that markings are irrelevant, undercutting her central explanation. The agreement states "classified information is marked or unmarked … including oral communications."
