OF COURSE THEY DID: Did Team Hillary remove classification markings from documents on her server?

Classified material -- especially TS/SCI material -- is held on systems that are physically and electronically separate from GENSER (general service) systems holding unclassified and official use only material. For TS/SCI material to be found on Hillary's server, it had to have been downloaded from the classified system to a removable media (for example, a USB drive), transported to an unclassified system and uploaded. There's no other way.

And that's a felony: 10 years and a $10,000 fine on the paperwork I signed (repeatedly) when I held such clearances.
