More information about the confusion in the days following the Sept. 11 attack on the US consulate in Libya: Emails obtained by Reuters show that scarcely more than two hours after the attack, the White House, Pentagon, and FBI were informed by the State Department's Operations Center that a Libyan militant group had claimed responsibility. One early email, obtained from anonymous sources, carried the headline, "Ansar al-Sharia Claims Responsibility for Benghazi Attack."
US intelligence officials have said that initial reports are difficult to analyze, and that they were "relying on the best analysis available at the time." Hillary Clinton responded to the report today, pointing out that the email was referring to a Facebook post from the militant group. "Posting something on Facebook is not in and of itself evidence," Clinton said. "I think it just underscores how fluid the reporting was at the time and continued for some time to be."
