Have you heard or entertained any interesting conspiracy theories associated with David Petraeus' resignation as D/CIA?

The news story is that he was involved in a secret extra marital affair, got found out and resigned.

This weekend I was with friends and everybody seemed to have a spin on this story.

FBI, Libya, blackmail etc etc etc.

I figure it is pretty simple. He got caught with another woman, couldn’t deny it, resigned to try to minimize the bullshit.

But maybe there is more…

What theories have you heard? What theories do you imagine?
