Hillary Clinton Defends Not Knowing State Department Classification Markings

"With respect to classification, on classified documents there is what's called a header. It says this material is top secret, secret, or confidential. There were no headers on the thousands of emails that I send or received. There just weren't and the FBI has in no way contradicted that. There were a couple of emails with a tiny 'C' in parentheses which did not have a header saying that it means confidential in this circumstance, and which the director of the FBI has said and State Department has said, those couple of mails were improperly marked even with that. So, yes, I take classification seriously and I think the record shows I have."
