WASHINGTON-- Former CIA Director David Petraeus will testify before the House Intelligence committee Friday on events that led to the death of the U.S. ambassador and three other Americans in an attack on the U.S. Consulate at Benghazi, Libya, on Sept. 11.
Spokesmen for the committee say the hearing will be closed to the public.
Petraeus resigned from the CIA last week after acknowledging an extramarital affair. The liaison was discovered during an FBI investigation of harassing emails allegedly sent by Petraeus' biographer and mistress, Paula Broadwell, to Tampa socialite Jill Kelley. Broadwell allegedly saw Kelley as a rival.
The probe expanded to include Kelley's copious communications with the top U.S. commander In Afghanistan, Marine Gen. John Allen.
Meanwhile, a federal law enforcement official says that the ex-CIA director's biographer and lover sent emails to other senior military officials besides the top U.S. commander in Afghanistan.
The official characterizes the emails as an attempt to undermine the reputation of a Tampa socialite who was friendly with David Petraeus and Gen. John Allen.
The official, who wasn't authorized to discuss the case publicly, spoke on the condition of anonymity.
The emails were traced to Paula Broadwell, the former CIA director's mistress.
