PORTLAND, Maine — Former U.S. Rep. Gabby Giffords says “stopping gun violence takes courage” as she returned to Maine to urge voters to support expanded background checks for gun purchases.

Giffords appeared at Congress Square Park in Portland on Wednesday alongside Portland Police Chief Michael Sauschuck and a citizen co-sponsor of Question 3 on the Nov. 8 ballot in Maine.

It was the 17th stop in her six-week, 14-state “Vocal Majority” tour to urge Americans to vote to help stop gun violence.

Giffords was severely wounded in a 2011 shooting in Tucson that killed six people.

The former Arizona congresswoman is no stranger to Maine. She visited the University of Southern Maine campus in 2014. She and her husband, Mark Kelly, kicked off the latest bus tour on Sept. 27 in Orlando, Florida.
