Lawmakers from the District of Columbia and Maryland were scheduled to speak Saturday. Actress Kathleen Turner was expected to appear, along with Marian Wright Edelman of the Children's Defense Fund and Colin Goddard, a survivor from the Virginia Tech massacre.
Smith said she supports a comprehensive look at mental health and violence in video games and films. But she said the mass killings at Virginia Tech and Aurora, Colo., and Newtown, Conn., all start with guns.
"The issue is guns. The Second Amendment gives us the right to own guns, but it's not the right to own any gun," she said. "These are assault weapons, made for killing people."
