Mother of murdered girl featured in gun control ad

On the two-year anniversary of the Tucson, Ariz., shooting, Roxanna Green, the mother of 9-year-old Christina-Taylor Green, who was murdered during the rampage, is in a new gun control ad. The Demand a Plan campaign previously featured Aurora survivor Stephen Barton.

Meanwhile, initial efforts by the 113th Congress to pass gun control legislation are running up against opposition.
