U.S. Marine Lt. Gen. John Allen talks in the East Room of the White House in this April 28, 2011 file photo during U.S. President Barack Obama's announcement that then CIA Director Leon Panetta would be nominated as Secretary of Defense. Former CIA Director David Petraeus will testify November 16, 2012 on Capitol Hill about the recent attack on the U.S. diplomatic mission in Benghazi, Libya, but is also expected to be asked about his resignation last week over an extramarital affair. An FBI investigation revealed Petraeus' affair with his biographer Paula Broadwell. The probe also ensnared General John Allen, the commander of NATO forces in Afghanistan, whom agents found had exchanged "flirtatious" emails with Kelley, law enforcement officials said.
