Benghazi story disputed

The chairman of the Joint Chiefs of Staff said Wednesday that four members of Army special forces in Tripoli were never told to stand down after last year's deadly assault on the U.S. diplomatic mission in Benghazi, Libya, disputing a former top diplomat's claim that the unit might have helped Americans under siege. Army Gen. Martin Dempsey said timing and the need for the unit to help with casualties from Benghazi resulted in orders for the special forces to remain in Tripoli.
