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 held by the Senate 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.

It was unclear at first whether or not Petraeus would testify as planned, after he abruptly resigned from the agency amid news of his affair with biographer Broadwell. Five days ago, the Senate Intelligence Committee said the retired General would skip the hearing.

Sen. Dianne Feinstein, D-Calf., said Wednesday that Petraeus "willing and interested" to talk to the committee, CBS News' Stephanie Condon reported earlier Wednesday.
