Republican presidential hopefuls Donald Trump and Ted Cruz will also make their way to Phoenix. Trump is planning a gathering in Fountain Hills on Saturday. Cruz is attending "An American Rally" at Arizona Christian University on Friday, with former Texas Gov. Rick Perry and conservative TV and radio host Glenn Beck by his side.
Last week, Green Party candidates Jill Stein and Kent Mesplay were in Tucson. Stein paid a visit to Oak Flat and the U.S.-Mexico borderlands.
The Sanders rally is at the Tucson Convention Center and is scheduled for 7:30 p.m. It is free, but organizers are encouraging people to RSVP. Doors open at 4:30 p.m. Organizers also ask attendees to only bring small personal items, such as keys and cell phones, for security reasons. Weapons, sharp objects, chairs, and signs or banners on sticks will not be allowed.
