Vermont Sen. Bernie Sanders will campaign again in Minnesota prior to next week's presidential caucus.

Sanders has scheduled a Friday morning rally at Hibbing High School. He is locked in a tough battle with former Secretary of State Hillary Clinton for the Democratic presidential nomination.

Minnesota is one of a dozen states participating in the Super Tuesday set of primaries and caucuses on March 1. The Sanders and Clinton campaigns have both put resources into Minnesota, both through grassroots organizing and ads on TV and radio.

The Clinton campaign announced earlier Wednesday that Wendy Davis, a Texas Democrat who's popular with party activists, would be in Minnesota on Sunday and Monday to campaign for Clinton.
