Maybe he was being blackmailed into silence, and decided, screw it. I’m coming clean, then gonna speak out on Benghazi.
Just a hypothesis....
That was my first reaction to the story. And if he is still to be part of the coverup as many seem to think, what possible advantage could there have been for him to confess an affair and resign?
I'm hoping he's clearing away a blackmail situation and planning to tell the truth at the hearings.
