Watch Live: Senate Judiciary Committee holds hearing on reducing gun violence

The Senate Judiciary Committee on Tuesday morning is hosting the first in a set of several hearings on addressing ways to reduce gun violence. The hearing was scheduled before a shooting in Boulder, Colorado, left 10 people dead, including a police officer. 

Senators are questioning eight witnesses at the hearing, including a Connecticut police chief, Chicago trauma surgeon and the executive director at the Giffords Law Center to Prevent Gun Violence. The committee said it will use the hearing to examine community -based approaches to fighting gun violence, law enforcement and public health.  Judiciary Committee Chair Dick Durbin began the hearing by saying that he could ask for a moment of silence to commemorate the victims of the latest shooting, but what he wants is a moment of action.
