My guess is, she’s a Dem mole. Her mission was to engulf Petraeus in an affair to neutralize him.
She’s probably under contract for the NSA or another shadowy agency, all along. Her body is a bit too tempting to have been coincidentally in that position with Petraeus (so to speak..LOL)
I doubt that. They met in 2006, when he was an up-and-comer but not yet a hero. He was just another General.
