Giffords "horrified" by Colorado shooting

Former Rep. Gabrielle Giffords, who is recovering from wounds sustained during a January 2011 shooting spree in her Arizona district, was "horrified" to hear about the mass shootings in Aurora, Colorado overnight, according to a Tweet from her husband, Mark Kelly.

"Gabby and I were horrified to hear of the tragedy in Colorado last night," Kelly wrote. "Our thoughts and prayers are with the victims and their families."

Giffords resigned from Congress in January to focus on her recovery.
