Petraeus outed by Gmail

As reported earlier today, CIA chief David Petraeus has resigned after an FBI probe into whether someone else was using his email led to the discovery he was having an extramarital affair.

The Wall Street Journal reports that the investigation focused on his Gmail account, and that the traffic they observed "led agents to believe the woman or someone close to her had sought access to his email." The woman in question has now been identified as West Point graduate Paula Broadwell, author of "All In: The Education of General David Petraeus."

While Mr. Petraeus was still a general, he had email exchanges with the woman, but there wasn't a physical relationship, the person said. The affair began after Mr. Petraeus retired from the Army in August 2011 and ended months ago, the person said.
