Former Rep. Gabrielle Giffords stars in a new television ad–the first from her super PAC Americans for Responsible Solutions–in which she urges Congress to act immediately on legislating universal background checks for gun sales.

The 30-second spot opens with somber black-and-white images of post-shooting vigils in Aurora, Colo., Tucson, Ariz., Oak Creek, Wis., and Newtown, Conn. Giffords, whose speech is still affected from having been shot in the head in Tucson just over two years ago, narrates the whole thing and appears alongside her husband, former astronaut Mark Kelly.
