Sen. Lindsey Graham, R-S.C., issued a sharp and unusual challenge to the truthfulness of the nation's top uniformed military commander on Thursday, demanding that U.S. Army Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, return to Capitol Hill to provide fresh testimony on the Benghazi attacks.
The point of contention involved whether any military officers issued an order to U.S. armed forces personnel on the night of Sept. 11, when the U.S. consulate and a nearby annex came under terrorist attack, to "stand down" from providing assistance.
