Former congresswoman Gabrielle Giffords will stump for Minnesota statehouse candidates on Wednesday in Apple Valley and Minnetonka during a 14-state tour urging new gun-control laws.

Since a 2011 shooting that left Giffords, 46, critically injured, the Arizona politician has become a vocal advocate for passage of gun-control measures. She is co-founder of Americans for Responsible Solutions, a political action committee.

Democrats nationally are targeting a growing number suburban voters who say they would support modest gun control measures after a spate of high-profile mass shootings in the U.S.

Giffords will attend the kickoff of canvassing efforts at the DFL's Minnetonka field office at 3 p.m. Wednesday. She will be joined by House candidates Laurie Pryor and Ginny Klevorn.

Later Wednesday she will appear at the kickoff of phone banking efforts at the Apple Valley field office, where Giffords is stumping for state Sen. Greg Clausen and House candidates Lindsey Port and Erin Maye Quade.
