California Sen. Kamala Harris will campaign in Michigan for Joe Biden on Monday, appearing with him at a 7 p.m. rally at Renaissance High School.

The event is open to the public, and people are being asked to RSVP here.

The campaign rally is occurring on the eve of Michigan’s presidential primary, which has developed into a two-man race between Biden and Vermont Sen. Bernie Sanders.

The big question for Democrats: Is Sanders or Biden more likely to beat Trump?

Harris endorsed Joe Biden on Sunday and said she would "do everything in my power'' to help elect him, becoming the latest dropout from the Democratic race for president to line up behind the former vice president.

Her endorsement further solidifies the Democratic establishment’s move to consolidate around Biden, who has been endorsed by a number of prominent Michigan Democrats in recent days, including Gov. Gretchen Whitmer, former Gov. Jennifer Granholm; former U.S. Sen. Carl Levin; U.S. Rep. Haley Stevens, D-Rochester Hills; U.S. Rep. Elissa Slotkin, D-Holly; U.S. Rep. Brenda Lawrence, D-Southfield; State House Democratic Leader Christine Greig, and the United Food and Commercial Workers Union Local 876 and 951 in Michigan.
