Judicial Watch Uncovers Five More Clinton Emails Containing Classified Material on Her Unsecure, Non-‘State.gov’ Email System

We are still "proving" that Hillary's State Department sent and received Classified emails.  Why?  

Understand,  all State Department emails were sent or received via Hillary's private server  . . . .  all of them.  Hillary, to this day,  continues to deny that classified emails were sent or received,  and,  her lap-dog media allows her to cited this preposterous lie.  

A lie?  Yes.  And we know this because the State Department simply cannot exist without the benefit of classified emails . . . .  . . .   and documents.  Dozens of such documents are sent and received each and every day.  This particular Hillary Lie,  borders on silly/stupid,  and should be considered an admission of a cover-up of some kind.
