Jill Kelley is a fixture on the Tampa, Florida, military scene, volunteering for community relations work with foreign military officers and their families stationed at MacDill Air Force base.

She is also a friend of David Petraeus, and yet, she appears to have contributed to his stunning downfall and departure as director of the CIA.

It was Kelley's complaints about harassing emails from the woman with whom Petraeus had an extramarital affair, Paula Broadwell, that prompted an FBI investigation that later exposed the liaison and led to his resignation last week.
