One day after a mass shooting in California that killed 14 people and wounded 21, Republicans and Democrats in the U.S. Senate jousted on Thursday over gun control but again failed to advance legislation addressing the violence.
Democrats tried to expand background checks to those purchasing weapons at gun shows and through intrastate Internet transactions. They also proposed closing a loophole allowing people on "terror watch lists" to buy guns and explosives.
Both efforts failed in the face of heavy Republican opposition.
