Lt. Col. Wood has told CBS News and congressional investigators that his 16-member team and a six-member State Department elite force called a Mobile Security Deployment team left Libya in August, just one month before the Benghazi assault. Wood says that’s despite the fact that US officials in Libya wanted security increased, not decreased.

Wood says he met daily with Stevens and that security was a constant challenge. There were 13 threats or attacks on western diplomats and officials in Libya in the six months leading up to the September 11 attack…

Wood, whose team arrived in February, says he and fellow security officials were very worried about the chaos on the ground. He says they tried to communicate the danger to State Department officials in Washington, D.C., but that the officials denied requests to enhance security.
