Giffords, husband tout background checks
Both spoke at rally in same place where Giffords was shot
Gabrielle Giffords, a former congresswoman shot and wounded more than two years ago, urged support for background checks on Wednesday.
She and her husband, Mark Kelly, spoke at a gun control rally in Tucson, Arizona, the same place where an assailant shot her in the head.
Kelly said his newly formed gun-control organization is sending a letter to U.S. Sens. John McCain and Jeff Flake, both Arizona Republicans, urging them to support background-check legislation.
