PORTLAND, Maine (AP) - Former U.S. Rep. Gabby Giffords is returning to Maine to urge voters to support expanded background checks for gun purchases.

Giffords is expected to be at Congress Square Park in Portland to talk about Question 3 on the Nov. 8 ballot in Maine. It's the 17th stop in her six-week, 14-state national "Vocal Majority" tour to urge Americans to vote to help stop gun violence.

She 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.
