In an emotional session on the House floor this morning, Arizona Congresswoman Gabrielle Giffords offered her resignation a little more than a year after being shot in the head. 

Prior to her resignation, Giffords voted in favor of her anti-smuggling bill, which she introduced shortly before being shot last year. It passed unanimously, 408-0, with 26 members missing the vote.
