From CBS News:
(CBS News) In the weeks before his death, U.S. Ambassador Chris Stevens sent the State Department several requests for increased security for diplomats in Libya.
Stevens and three other Americans were killed in a terror attack this past Sept. 11 at the U.S. Consulate in Benghazi and a separate attack that same night on a safe house where consulate staff had been evacuated.
Steven's memos to the House Oversight and Government Reform Committee, which is investigating attacks, show he personally pressed for strengthened security.
