Gen. David Petraeus will testify before a House Committee on the Libya embassy attack Friday morning, despite the ongoing FBI investigation into an extramarital affair that led to his resignation as director of the CIA. The hearing to be held by the House Intelligence Committee is closed to the public and the media. Petraeus is expected to answer questions about the CIA’s knowledge and handling of the assault on the U.S. Consulate in Benghazi that left U.S. Ambassador Chris Stevens and three other Americans dead. Two of those Americans were with the CIA.
