The take I have is focused on her lies to Congress...under oath. Comey indicated their investigation found Clinton did in fact send and receive messages marked classified, secret, top secret and SAP.
Clinton before congress testified, under oath, she did not send any messages marked.....
Perjury!
When I was in the military, documents were labeled confidential, secret, top secret, and top secret--codeword. I recall none that were marked merely "Classified".
Lawyer Hillary is duplicating what Lawyer Bill said about "the meaning of is".
