Benghazi fallout?

(CNN) – CIA Director David Petraeus submitted his resignation to President Barack Obama, citing personal reasons, a U.S. government source told CNN.

The source said Petreaus admitted to an extra-marital affair.

In a statement issued Friday, he said: “After being married for over 37 years, I showed extremely poor judgment by engaging in an extramarital affair. Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours. This afternoon, the President graciously accepted my resignation.”

Update: This thing stinks to high hell.

Will Congressional Republicans subpoena him to force him to testify?
