FILE - In this Wednesday, March 6, 2013 file photo, former U.S. Rep. Gabrielle Giffords smiles as she raises a fist pump to the crowd as she, husband Mark Kelly, and a number of other Tucson mass shooting victims returned to the site of the shooting in Tucson, Ariz., that left her critically wounded to urge key senators to support expanded background checks for gun purchases. Giffords has been named this year's recipient of the John F. Kennedy Profile in Courage award. The JFK Library and Museum announced Friday that the Arizona Democrat is being honored for the "political, personal, and physical courage she has demonstrated in her fearless public advocacy for policy reforms aimed at reducing gun violence."
