ANDOVER, Minn. (AP) — Marco Rubio will campaign in Minnesota on Super Tuesday as he tries to stall Republican presidential front-runner Donald Trump.

Rubio is scheduled to appear at a rally Tuesday afternoon at the Courtyards of Andover Event Center in Andover. The Florida senator also held a rally in Minneapolis last week.

Rubio and Ted Cruz are battling to emerge as the strongest GOP alternative to Trump. Minnesota is one of 12 states casting votes for presidential hopefuls on Tuesday.

Rubio recently picked up endorsements from former Minnesota Gov. Tim Pawlenty, former U.S. Senators Norm Coleman and Rudy Boschwitz, and U.S. Representative Erik Paulsen.

Former Republican presidential candidate Rick Santorum is scheduled to make a stop in Rochester Monday to campaign for Rubio.  He is expected to attend an event at Godfather’s Pizza at noon.  

Meanwhile, Democratic presidential hopeful Bernie Sanders is returning to Minnesota a day ahead of the state's precinct caucuses on Super Tuesday.

Sanders' campaign says he will host a rally at the Minneapolis Convention Center on Monday,

Sanders was in Minnesota last week for rallies in Hibbing and Rochester. He congratulated Hillary Clinton "on a very strong victory" in the South Carolina primary Saturday and noted that more than 800 delegates are at stake in 11 contests on Super Tuesday.

Minnesota holds its caucuses on Tuesday and is among those Sanders is targeting for victory.
