According to the Washington Post, an ex-military officer in Libya, Lt. Col. Andrew Wood, is expected to deliver testimony before Congress later Wednesday during a hearing of the House Oversight and Government Reform Committee.

The development adds fuel to Republicans' fire in asserting the U.S. has been more concerned with "presenting a picture of an improving situation in Libya than in ensuring the safety of its staff there."

From Wood's testimony: "The situation remained uncertain and reports from some Libyans indicated it was getting worse. Diplomatic security remained weak."

Deputy Assistant Secretary of State Charlene Lamb and Undersecretary of State Patrick Kennedy also prepared testimony for the session, titled "Security Failures of Benghazi."
