Minnesota Gov. Tim Walz, the Democratic vice presidential nominee, is making a campaign swing through Arizona on Wednesday, as early voting in the critical swing state begins.

Walz will start in Chandler, Ariz. — a town outside of Phoenix — with a campaign event alongside Rep. Ruben Gallego (D-Ariz.). Gallego, who is running for the Senate, is set to debate his GOP rival Kari Lake on Wednesday evening.

Later, the Minnesota governor will travel to Phoenix and Tucson. His Republican counterpart, Sen. JD Vance (R-Ohio) will also be in the Grand Canyon State on Wednesday.

The Hill/Decision Desk HQ’s polling index shows former President Trump, Vance’s running mate, slightly ahead with 48.7 percent support to Vice President Harris’s 47.9 percent.

The event in Chandler is scheduled to begin at 2 p.m. EDT.
