The Senate Intelligence Committee responsible for the investigation is reportedly frustrated with the lack of information federal agencies are providing.
[Dianne] Feinstein (D., Calif.) and her Republican counterpart, Sen. Saxby Chambliss (R., Ga.) reportedly expressed frustration that federal agencies still have not provided requested information on the Benghazi controversy. Also, reportedly frustrating Feinstein and Chambliss: the State Department declined the committee's request to hear from Charlene Lamb, who was in charge of all U.S. diplomatic security and previously testified to a House Committee that security in Libya was adequate.
