Article Photos: Timeline of events in Petraeus case 1/3

  This July 13, 2011, photo made available on the International Security Assistance Force's Flickr website shows the former Commander of International Security Assistance Force and U.S. Forces-Afghanistan Gen. Davis Petraeus, left, shaking hands with Paula Broadwell, co-author of "All In: The Education of General David Petraeus."As details emerge about Petraeus' extramarital affair with his biographer, Broadwell, including a second woman who allegedly received threatening emails from the author, members of Congress say they want to know exactly when the now ex-CIA director and retired general popped up in the FBI inquiry, whether national security was compromised and why they weren't told sooner.
