Walking with a limp, Giffords smiled warmly as she met supporters at the Gabrielle Giffords Family Assistance Center in Tucson, Arizona, a food bank established with money donated after she was shot a year ago.

"I don't remember much of that terrible day," Giffords said in a video where she announced her resignation.
