Staffers at State Department headquarters in Washington, D.C. held their own private ceremony Wednesday to commemorate the first anniversary of the attack on the U.S. consulate in Benghazi, Libya after finding out the agency would not be organizing a formal, official memorial service. The Sept. 11, 2012 Benghazi attack left four people dead, including the American Ambassador to Libya, Chris Stevens, and Sean Smith, an information management officer in the department's foreign service.
