The panel included attorney Gayle Trotter, the only woman in the group, and she pegged herself as the voice for women in the gun violence debate at the hearing.

The president's plan included 23 executive actions on gun violence that would not require congressional approval, which included a directive for national agencies to strengthen the criminal background check system.
A new ABC News-Washington Post poll out last week showed 53 percent favored the president's gun control plan while 41 percent viewed it unfavorably.
