Veteran to Clinton: How Can We Have Confidence in You When You’ve ‘Corrupted Our National Security?’

CLINTON: "Well, I appreciate your concern and also your experience. But let me try to make the distinctions that I think are important for me to answer your question. First, as I said to Matt, you know and I know, classified material is designated, it is marked. There is a header so that there is no dispute at all that what is being communicated to or from someone who has that access, is marked classified. And what we have here is the use of an unclassified system by hundreds of people in our government to send information that was not marked, there were no headers, there was no statement, top secret, secret, or confidential. I communicated about classified material on a wholly separate system."
