A law enforcement official says a shooting at the United States Capitol is related to a vehicle that tried to ram a security barricade at the White House.
The official says a driver tried to drive through a barricade that blocks the stretch of Pennsylvania Avenue in front of the White House to vehicles. The driver then proceeded down Pennsylvania Avenue to Capitol Hill, where shots were fired.
The official was not authorized to publicly discuss the incident by name and insisted on anonymity.
