CIA Director General Petraeus Resigns

[Keith Millea]

Speaking on CNN, former CIA operative Bob Baer noted that while resignations from extramarital affairs are not unheard of at the agency, they are almost never the announced reason for giving up the post.
"I think there's a big story behind it," Baer said.

FWIW:One commenter mentioned something about the FBI investigating his girlfriend because of apparent hacking of his email.So,basically,he was forced to come clean.
