WASHINGTON (AP) -- 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.
Meantime, Defense Secretary Leon Panetta says he knows of no other senior U.S. military officers being linked to the David Petraeus investigation that has ensnared the top U.S. commander in Afghanistan, Gen. John Allen.
Speaking at a Bangkok news conference today, Panetta said he retains confidence in Allen.
Panetta declined to describe the nature of the emails and other correspondence between Allen and Florida socialite Jill Kelley, which others have called flirtatious and possibly problematic.
The defense chief says he wants to be careful with his words in order not to jeopardize the Pentagon inspector general investigation he ordered Monday.
Panetta also told reporters that he could not rule out that the Taliban in Afghanistan might try to use Petraeus' admission of an extramarital affair for propaganda purposes.
