TUCSON, Ariz. (AP) - Former Rep. Gabrielle Giffords is urging key senators to support expanded background checks for gun purchases.
Giffords is scheduled to hold a news conference in Arizona Wednesday to promote tougher firearm regulations.
Giffords was among 13 people wounded in a January 2011 shooting rampage as she met with constituents outside a Tucson supermarket. Six people were killed.
Other survivors of the mass shooting are expected to join Giffords at the news conference in Tucson Wednesday.
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.
The Senate Judiciary Committee is scheduled to take up tougher firearm regulations Thursday.
Kelly traveled to Colorado Monday to urge state lawmakers to pass universal background checks.
