US Officials Explain Libya Attack Intelligence U.S. intelligence officials sought to explain Friday why the Obama administration's understanding of the Sept. 11 attack on the U.S. Consulate in Benghazi is "evolving." Facing a barrage of Republican criticism about what the administration knew and when about the attack, the Office of the Director of National Intelligence issued a statement Friday that laid out how officials came to understand the assault that killed U.S. Ambassador Chris Stevens and three other Americans. At the same time, the U.S. ambassador to the United Nations issued a statement explaining her early descriptions of the attack. In the days immediately after the attack, the administration said it believed it was a spontaneous reaction to an anti-Islamic video that ridiculed Islam's Prophet Muhammad and ignited mob protests on U.S. embassies around the Middle East and in North Africa. Now, the administration has begun to call it a terrorist attack carried out by al-Qaida-linked militants and explain that it was a planned attack distinct from the mob protests in the region. Republicans have seized on the Obama administration's changing narrative, saying the administration was too slow to label it a terrorist attack because, they said, the White House did not want to admit its policies had failed to defeat al-Qaida, and quell anti-American sentiment in the Muslim world. "Throughout our investigation we continued to emphasize that information gathered was preliminary and evolving," DNI spokesman Shawn Turner's statement said. It remains unclear if any group or person exercised overall command and control of the attack, and if extremist group leaders directed their members to participate. However, we do assess that some of those involved were linked to groups affiliated with, or sympathetic to al-Qaida," he said. At the same time, a spokeswoman for U.N. Ambassador Susan Rice also sought to explain comments that Rice made early in the investigation saying there was no evidence the Benghazi attack was premeditated. During her appearances on the Sunday talk shows Sept. 16, 2012, Ambassador Rice's comments were prefaced at every turn with a clear statement that an FBI investigation was under way that would provide the definitive accounting of the events that took place in Benghazi," said Erin Pelton, spokeswoman for the U.S. Mission to the United Nations. At every turn Ambassador Rice provided - and said she was providing - the best information and the best assessment that the administration had at the time, based on what was provided to Ambassador Rice and other senior U.S. officials by the U.S. intelligence community. Further intelligence may be slow to arrive. The FBI team that arrived in Libya last week to investigate the incident can't get to the scene of the attack because it is too dangerous, according to two law enforcement officials. The officials requested anonymity because they are not authorized to speak publicly about an ongoing investigation. Republicans have seen the Libya attack as an opportunity to attack President Barack Obama on one of his strengths, foreign policy. GOP presidential nominee Mitt Romney accused the administration of being dishonest. I think it's pretty clear that they haven't wanted to level with the American people. We expect candor from the president and transparency," Romney told Fox News this week.
