Former Rep. Gabrielle Giffords returned Wednesday to the site of the Jan. 8, 2011 shooting in Tucson to urge U.S. senators to support expanded background checks for gun purchases.
She was scheduled to speak to reporters in the parking lot of the Safeway grocery store at North oracle and East Ina roads to promote tougher firearm regulations.
Giffords, a Democrat, was among 19 people shot at a gathering of her constituents. Six were killed, including a 9-year-old girl, a federal judge, a Giffords staff member and three constituents.
Other survivors were expected to join Giffords at the news conference.
Americans for Responsible Solutions, a gun control group started by Giffords and husband Mark Kelly, began airing a new television ad in Arizona and Iowa Tuesday calling for background checks.
