Petraeus 'to say he knew quickly who was behind Benghazi attack' President Barack Obama's administration is under fire from opposition Republicans over the inadequate security at the consulate and for giving a changing narrative about the assault. The US ambassador to the United Nations, Susan Rice, has come under withering criticism for, five days after the attack, blaming it on a spontaneous demonstration against a film that had set off earlier riots in Cairo. Ms Rice's comments were based on initial intelligence that later proved incorrect, the deputy CIA director told Congress on Thursday. In a closed-door session with the House Intelligence committee, Mike Morell said Ms Rice was provided with an unclassified version of events during the attack, according to Democratic Rep Adam Schiff, a member of the panel. Mr Schiff told reporters that he didn't think the intelligence community had politicized the information. "They gave us the best initial assessments, and those proved inaccurate, but they warned us those assessments were subject to change as they got more information," he said. When asked how Mr Petraeus might address that issue, CNN said its source suggested Ms Rice may have gotten information from other parts of the administration, not just the intelligence community. An outraged Mr Obama on Wednesday accused Republicans, including leading Senator John McCain, of besmirching Ms Rice's reputation without cause and said they should go after him on Benghazi rather than just pick on an easy target. On Thursday, senators got their first look at dramatic video footage of the attack. "The film is a composite from a number of sources," said Senator Diane Feinstein, chairwoman of the Senate Intelligence Committee, after she and her colleagues attended a closed door viewing "It is real time and it begins before the incident started and it goes through the incident and the exodus," she added. The deputy chairman of the panel, Senator Saxby Chambliss, said the hearing with US intelligence officials made clear that errors were committed. "We know mistakes were made and we have to learn from that," he told reporters. He said there would eventually be public hearings and "the American people are going to have the opportunity to see the questions asked and get the answers to questions that they have had since September 11th of this year."
