Former congresswoman Gabrielle Giffords (D-Ariz.) is expected to give an opening statement Wednesday at a Senate hearing on gun violence, lending the emotional resonance of her experience with the issue to what had already promised to be a dramatic exchange between lawmakers and advocates for and against stricter gun-control laws.

The Senate Judiciary Committee will hold its first hearing on gun-related violence in 14 months on Wednesday morning, and observers expect that it will help set the tone for congressional debates over legislation introduced in the wake of the deadly shooting last month at an elementary school in Newtown, Conn., that killed 26 people, including 20 young children.
