'Classified material has a header, which says 'top secret', 'secret', 'confidential'. Nothing, and I have repeatedly said this, and this is verified in the report by the Department of Justice. None of the emails sent or received by me had such a header.'
Wikileaks showed why:
They say they've had issues sending secure fax. They're working on it.
If they can't, turn into nonpaper w no identifying heading and send nonsecure.
Simple math. The reason the emails on her server had no classified markings was because she had them removed. The reason the (c) remained is because she didn't know what it meant and forgot to have it removed.
Pardon the horrible writing style and weird fonts, but I am at work and just had to get this out of my head.
