Vermont Sen. Bernie Sanders, who has emerged as a serious threat to Hillary Clinton's position as frontrunner in the Democratic presidential race, will campaign in Minnesota on Tuesday. 

The Sanders campaign announced Friday that he would hold an afternoon rally at the Duluth Entertainment Convention Center and an evening event at St. Paul's RiverCentre.

"Sanders will discuss a wide range of issues, including getting big money out of politics, combating climate change and making college affordable," according to a press release from the campaign. 

The event is free and open to the public. Admission is first come, first served. 

Sanders, an independent senator and socialist, has overtaken Clinton in several recent polls of voters in Iowa and New Hampshire, the first two states to weigh in on the presidential contest next month. Minnesota's presidential caucus is on March 1. 

Clinton delivered a major campaign policy speech in Minnesota in December. She, Sanders and Maryland Gov. Martin O'Malley will all be back in the Twin Cities in February to speak at a DFL annual dinner.
