U.S. Rep. Gabrielle Giffords of Arizona was shot outside a grocery store in Tucson while holding a public event, Arizona Public Media reported Saturday.

Giffords, who was re-elected to her third term in November, was hosting her first “Congress on Your Corner” event at the Safeway in northwest Tucson when a gunman ran up and started shooting. At least five other people, including members of her staff, were hurt, according to Peter Michaels, news director of Arizona Public Media.
