HIBBING, Minn. (AP) - Sen. Bernie Sanders brought his presidential campaign to northern Minnesota just days ahead of the state's presidential caucuses.

Minnesota is one of 12 states with voters going to the polls on Super Tuesday.

Sanders met with steelworkers and representatives of Minnesota's American Indian tribes before addressing a crowd at Hibbing High School. Sanders continued to rail against establishment politics and economics. Some supporters waited outside the high school in cold temperatures for nearly two hours before the rally.

It's Sanders second stop in northern Minnesota. His rally in Duluth last month drew about 6,000 people.

Sanders plans to campaign in Rochester on Saturday.
