DES MOINES, Iowa (AP) — Former Arizona Rep. Gabby Giffords says that “dangerous people with guns are a threat to women.” She appeared in Iowa on Tuesday to rally female voters and inject gun control into one of the nation’s marquee Senate contests two weeks before Election Day. Giffords is nearing the end of a two-week national tour that includes stops in Minnesota, Oregon and Washington State this week.

The Arizona Democrat has become the reluctant face of the gun control movement. She was shot while meeting with constituents almost four years ago. The attacker killed six and left Giffords with permanent brain damage.

Giffords has pushed Congress unsuccessfully to expand background checks for all gun purchases. As the midterm elections approach, she’s fighting to ensure gun violence isn’t forgotten.
