There are growing questions about Paula Broadwell, the woman behind the resignation of General David Petraeus. Did the 40-year-old biographer to Petraeus have access to classified information during her affair with the now former CIA Director.
CNN has learned the affair started two months after Petraeus took over the CIA, which was back in September of 2011, and ended about four months ago.

Petraeus biographer made trips to Afghanistan
About four years ago, Paula Broadwell began her Ph.D. dissertation on Gen. David Petraeus' innovative leadership skills.
Some of the interviews were done via e-mail. Others were conducted as Broadwell occasionally ran with the physically fit four-star general, including one run with Petraeus and his team along the Potomac River in Washington.
Broadwell decided to turn that research into a book and go to Afghanistan after Petraeus was tapped in June 2010 to replace Gen. Stanley McChrystal as the top commander in the country.
