- An independent review of the September 11 attacks on the U.S. Consulate in Benghazi released Tuesday cited "systemic failures and leadership and management deficiencies" at the State Department. The attacks killed four Americans, including U.S. Ambassador J. Christopher Stevens. The failures resulted in a security plan "that was inadequate for Benghazi and grossly inadequate to deal with the attack that took place," the 39-page, unclassified version of the report concluded.
