Activists are using Tuesday's two-year anniversay of the mass shooting in Tucson to push for gun control measures.
Mayors Against Illegal Guns, founded by New York Mayor Michael Bloomberg, released a TV ad featuring Roxanna Green, mother of a nine-year-old girl killed that day. It will air on cable stations in Washington through Jan. 14 and in markets where there have been mass shootings: Tucson, Ariz., Waco, Texas, Roanoke, Va., Denver, Binghamton, N.Y. and Milwaukee.
The Brady Campaign to Prevent Gun Violence called it a “Day of Action,” challenging Americans to encouraging supporters to sign a letter on mass shootings, contact their elected officials and engage friends through social media.
Former Rep. Gabrielle Giffords and her husband, Mark Kelly, announced a political action committee, Americans for Responsible Solutions, and Website calling for contributions to help "encourage elected officials to stand up for solutions to prevent gun violence and protect responsible gun ownership."
“How many more children must die before Washington does something to end our gun violence problem?” Bloomberg said. “We need political leaders to hear Roxanna loud and clear: we cannot wait any longer for you to do something about gun violence. Another child should not have to die.”
