The key aspect to Julian Assange’s interview with Sean Hannity last night was Assange reminding everyone of the original WikiLeaks Cable scandal in 2010, and also pointing out that Hillary Clinton was the originating official of cables marked (c) “classified”.

Hillary Clinton authored the content of the cables (as described); and she herself has originating autonomy to designate material as “classified” or “confidential”.  Assange is essentially reminding everyone that Secretary Clinton assigned that designation personally.
It is ridiculous for Secretary Clinton to state she doesn’t know what the “(c)” designation is, she used it herself.
