Bernie Sanders is returning to Arizona on Tuesday to campaign for his former rival for the Democratic presidential nomination, Hillary Clinton.

Sanders, a U.S. senator from Vermont will make stops in Flagstaff and Tucson — two of Arizona's most Democrat-friendly areas — as he makes a swing through the Southwest.

Sanders is expected to tout Clinton's economic agenda at the stops as well as advocate for increasing the minimum wage, confronting climate change, making public universities tuition-free and fixing the "broken criminal justice system," the Clinton campaign said Sunday.

Sanders will appear Tuesday at a 2:30 p.m. Arizona Democratic Party get-out-the-vote rally at Prochnow Auditorium at Northern Arizona University, 307 W. Dupont Ave., Flagstaff.

Later, he will make another appearance at a 7 p.m. state party rally at Arizona State Museum, 1013 E. University Blvd., Tucson.

Clinton, a former U.S. secretary of state and former U.S. senator from New York, defeated Sanders in Arizona's March 22 Democratic presidential preference election, or primary.

Chelsea Clinton, the nominee's daughter, is set to appear Wednesday at a rally in Arizona State University's Memorial Union.

Polls have suggested that Arizona, usually a red state in presidential elections, could turn blue this election.
