Former CIA Director Gen. Davis Petraeus
shakes hands with biographer Paula Broadwell, co-author of All In: The
Education of General David Petraeus, on July 13, 2011. Petraeus, who popularized counterinsurgency strategy while overseeing the wars in Iraq and Afghanistan, resigned from his post at the intelligence agency on Nov. 9 over an
extramarital affair with Broadwell. The FBI began an
investigation after it was tipped off by Jill Kelley, a friend
of the Petraeus family who received threatening emails from Broadwell.
