TUCSON, Ariz. – Former Rep. Gabrielle Giffords is returning to the site of a shooting that left her critically wounded to urge key senators to support expanded background checks for gun purchases.
She's scheduled to speak to reporters Wednesday in the parking lot of a Safeway grocery store outside Tucson to promote tougher firearm regulations.
The Democrat was among 13 people wounded in the January 2011 shooting rampage as she met with constituents. Six people were killed.
Other survivors are expected to join Giffords at the news conference.
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.
Sheriff's deputies are at the event to provide security.
