Natalie Khawam, twin sister of Jill Kelley, cries during a news conference to explain her relationship with former CIA chief General David Petraeus and his wife Holly in Washington November 20, 2012. Anonymous emails that Paula Broadwell sent to Jill Kelley, a Tampa, Florida socialite who knew Petraeus, prompted an FBI investigation that exposed Broadwell's affair with Petraeus, a retired U.S. Army general known for his success in the Iraq war.
