Former CIA director David H. Petraeus told Congress on Friday that the Sept. 11 attack on the U.S. mission in Benghazi, Libya, was clearly an act of terrorism, but he did not resolve the question of when the agency reached that conclusion, according to law­makers who attended the closed-door sessions. Several members of the House and Senate intelligence committees who heard Petraeus's testimony said that he indicated he believed immediately after the incident that it was a terrorist attack. That appeared to conflict with testimony he gave them three days after the attack, when he said it appeared to have begun as a "spontaneous" assault that was overtaken by "extremists." Rep. Peter King (R-NY), chairman of the House Homeland Security Committee, briefed the press on former CIA Director David Petraeus" closed-door remarks on the attack on the U.S. consulate in Benghazi that killed four Americans, including U.S. Ambassador Chris Stevens. Sean Sullivan "It was like a lighting bolt," Senate Intelligence Committee Chair Dianne Feinstein (D-Calif.) said. Sari Horwitz and Greg Miller Messages" recipient was perceived by Paula Broadwell as a threat to her relationship with Petraeus. Joby Warrick, Ernesto Londoño and Kimberly Kindy Petraeus was always careful about managing his image, aides say. Ian Shapira Friends say Holly Petraeus has a lot of sympathy from military families, whom she has done much to help. The timing of the CIA's conclusion has become a contentious issue in Congress, where some prominent Republicans have charged that Susan Rice, the U.S. ambassador to the United Nations and President Obama's leading candidate to become secretary of state, knowingly presented a whitewashed account in television appearances on Sept. Reading from administration talking points, Rice hewed to the "spontaneous" theory, saying that the attack began as a protest against an anti-Islamic video that was privately produced in the United States and was hijacked by "opportunistic extremist elements." In the television interviews, she said this was the "best information" available, but stressed that the matter was under investigation. Petraeus, who has not appear­ed in public since he resigned last week after revelations of an extramarital affair, avoided a swarm of reporters and photographers awaiting his arrival for the early morning hearings held in secret briefing rooms three floors underground in the U.S. Capitol Visitor Center. You can blame it on us. We wanted to spare him," Sen. Dianne Feinstein (D-Calif.), who chairs the Senate panel, told reporters after Petraeus had left. Rep. Peter T. King (R-N.Y.) said the House panel had only briefly discussed the former general's affair with former Army officer Paula Broadwell and that Petraeus had assured them his resignation related only to that and not to the Benghazi attack. "He realizes what he's done [to] himself, and to the CIA," King told Fox News. He apologized, but once he got into his testimony, he was the same old General Petraeus. According to accounts provided by intelligence officials, the CIA concluded early on that Benghazi was a terrorist attack by definition, because any assault on a U.S. government installation with heavy weapons and substantial firepower could not be classified otherwise. The officials spoke on the condition of anonymity to discuss intelligence matters. In the swirl of initial reporting about the attack, which killed Ambassador J. Christopher Stevens and three other Americans, two accounts made their way into the first round of analysis, the officials said. Reports from the ground in Libya described a demonstration at the Benghazi mission, similar to a large anti-U.S. protest the same day outside the U.S. Embassy in Egypt.
