Sen. Mark Kelly says "there is more" Congress can do to address gun violence

In the wake of a mass shooting at a bank in downtown Louisville that killed five people and injured eight others, Arizona Senator Mark Kelly said he believes "there is more" that lawmakers can do to address gun violence in the United States beyond last year's Safer Communities Act.

Kelly — a Democrat whose wife, former Rep. Gabby Giffords, suffered a severe injury in a mass shooting in 2011 — discussed the bipartisan legislation on "Face the Nation" Sunday, describing it as "a step in the right direction" while calling for additional change. 

"We have some of the most permissive gun laws in the world and we have some of the highest levels of gun violence," Kelly told "Face the Nation" moderator Margaret Brennan. "We passed this bipartisan, Safer Communities Act. It is a step in the right direction, but it's only one step and there is more we can do."
