Ok. I admit I may not be fully aware of all the facts.
Petraeus gave classified information to an author who did not have clearance who then announced it (some time later) at a conference.
To whom did Clinton send classified information who was not cleared to have it? Sidney Blumenthal? My understanding is that he sent her classified information, not the other way around. Again, open to additional facts on this.
Well, she didn't know the stuff she was sending out with the (C) on top meant confidential...... so........
