TUCSON (KGUN9-TV) - Roughly 7,000 people attended a rally at the Tucson Convention Center for Senator Bernie Sanders on Friday night.
The presidential hopeful made a stop in Tucson after appearances in Phoenix and Flagstaff this week.
U.S. Rep. Raul Grijalva introduced Sanders. Grijalva says he is the first congressman to publicly support Sanders, and does not believe his campaign is over. When he mentioned that Donald Trump would be at the TCC Saturday, many in the crowd booed.
Sanders spoke for nearly an hour and touched on a variety of issues including reducing student debt, the treatment of Native Americans, banning private prisons, and raising the federal minimum wage to $15.
Earlier this week Sanders' wife Jane met with families of immigrants outside Maricopa County Sheriff Joe Arpaio's tent city.
"She asked him about keeping people in a tent where the temperature gets 130 degrees," Sanders said. "He had nothing significant to say. Let's be clear -- that type of behavior on the part of this sheriff is not what this country is supposed to be about."
In a Tweet earlier this week, Arpaio said he invited Jane Sanders inside so he could defend his tent policy. On Friday he sent out a Tweet that read, "Sanders threatening me? Sanders said "If I'm elected Pres of US I Will have power and Watch Out, Joe". I'm not concrnd, Sndrs won't be Pres."
Sanders also discussed immigration reform. If elected, he says he would end to the hatred and bigorty towards Mexicans expressed by other candidates.
"I have spoken to too many families, too many children, who are literally forced to live apart," Sanders said. "This is not acceptable."
Sanders went on to say that under his administration anyone who has been deported but would have been protected by the 2013 comprehensive reform bill will be allowed to return.
Sanders will take a trip Nogales on Saturday, and will be back in Phoenix for another appearance Saturday evening.
