Not sure if this will help but here is Col. David Hunt's complete radio interview after the Ryan/Biden debate. He was very angry because he knew Biden had lied in the debate. He explains how some things work in the chain of command and knew right away something wasn't right when he found out the emergency button in Benghazi had been tripped. It's pretty long but informative.
