The subpoena compels Lt. Col. Wood to appear at a House Oversight Committee hearing next week that will examine security decisions leading up to the Sept. 11 Muslim extremist terror assault on the U.S. compound at Benghazi. U.S. Ambassador Christopher Stevens and three of his colleagues were killed in the attack.
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.
