RALEIGH, N.C. (AP) -- Former Arizona Congresswoman Gabrielle Giffords and her husband have visited Raleigh as part of a nationwide tour to highlight ways they believe tougher laws can reduce gun violence.

Giffords was injured in January 2011 when a mentally ill man opened fire at an outdoor constituent event in Tucson, Ariz. Six people were killed, and 13, including Giffords, were injured. She and her husband, former astronaut Mark Kelly, are the co-founders of the gun violence prevention group Americans for Responsible Solutions.

Giffords and Kelly discussed ways that they say increased gun controls can coexist with the Second Amendment and the right of Americans to own guns. The event was not open to the public and was organized by Americans for Responsible Solutions.
