David Petraeus to Testify on Libya Declaring it the first step in a long fact-finding mission, the Senate Intelligence Committees met for just under four hours today, hearing testimony from acting CIA director Mike Morell and Director of National Intelligence James Clapper, among others, about the Sept. 11 attack on the U.S. consulate in Benghazi, Libya. On Friday morning, former CIA director David Petraeus is set to head to Capitol Hill to testify before the Senate and House intelligence committees about the attack on Benghazi, which led to multiple deaths, including that of Ambassador Chris Stevens. During the closed-door briefing today, the committee members saw a film put together by the National Counterterrorism Center of the events in Benghazi. Also testifying today were FBI Deputy Director Sean Joyce, Under Secretary of State for Management Pat Kennedy, and National Counterterrorism Center Director Matthew Olsen. The film is a composite from a number of sources. It is real-time and does begin from when before the incident started and it goes through the incident and the exodus," said Sen. Dianne Feinstein, D-Calif., chairwoman of the Senate Intelligence Committee. She added that the footage includes video shot from an unmanned aerial vehicle. But she did not answer whether the video showed Ambassador Chris Stevens, who was killed in the assault on the compound. Petraeus's testimony is much anticipated. "Director Petraeus went to Tripoli," Feinstein said. He interviewed many people, as I understand it, that were involved and so the opportunity to get his views is very important. Feinstein would not comment on the CIA's inspector general investigation into Petraeus' conduct regarding an extramarital affair with Paula Broadwell. "The purpose of this hearing is Benghazi," Feinstein said of Friday's hearing with Petraeus. We're not going into the FBI investigation or the inspector general or anything else. This is Benghazi. Petraeus, who resigned last week after disclosing an extramarital affair, is expected to defend the CIA's actions during the attack that killed Stevens and three other Americans. The retired Army general, who once commanded U.S. forces in Afghanistan, reportedly is eager to set out a timeline of events leading up to and during the deadly attack. Petraeus is not expected to discuss his resignation or the affair with Broadwell. The week after next, the committee will resume with another two full hearings. Feinstein predicted that the committee will then have an open, public hearing . "Gosh, we know mistakes were made," said Sen. Saxby Chambliss, R-Ga., ranking member of the committee. At the end of the day, our committee is going to get to the bottom of this. Adm. William H. McRaven, the head of U.S. Special Operations Command and the planner of the raid that killed Osama bin Laden in 2010, on Wednesday night called Petraeus "an American hero." The praise came at The Hero Summit, an event honoring the military sponsored by Newsweek-Daily Beast. McRaven said. I don't condone what he did, because Holly Petraeus is also a great American hero.
