(WASHINGTON) -- Former CIA Director David Petraeus has agreed to testify at a closed-door session of Congress to answer questions about September's terrorist attack on the U.S. consulate in Libya. Still, he will likely also be asked about new revelations that his alleged mistress, Paula Broadwell, is suspected of storing classified military material at her home.
Petraeus had been reluctant to testify following his resignation as CIA chief, but pressure had been growing in Congress for him to appear.
The former general has agreed, sources told ABC News, to testify on Thursday.
A source familiar with the case also told ABC News that Broadwell admitted to the FBI that she took documents from secure government buildings. The government demanded that they all be given back, and when federal agents descended on her North Carolina home Monday night, it was a pre-arranged meeting.
Prosecutors are now determining whether to charge Broadwell with a crime.
