A Texas congressman has identified the suspect in the shooting at Fort Hood as Ivan Lopez.
U.S. Rep. Michael McCaul, chairman of the House Homeland Security Committee, said Wednesday's shooting happened at a medical center at the base. Additional details about the suspect weren't immediately available.
U.S. law enforcement officials say four people, including the shooter, were killed when a gunman opened fire Wednesday at Fort Hood.
One of the officials, citing official internal U.S. Justice Department updates, said 14 others were hurt. The officials spoke on condition of anonymity because they were not authorized to release information by name.
The Texas Army base was the scene of a mass shooting in 2009.
