Gov. Rick Snyder is scheduled to serve as grand marshal of the annual Blossomtime Grand Floral parade in southwestern Michigan.
The parade is to take place Saturday in Benton Harbor and St. Joseph, about 70 miles southwest of Grand Rapids.
The Detroit News reports a Kentucky-based Democratic group plans to demonstrate at the parade in protest of Michigan's new law giving state-appointed financial managers broader powers in correcting the finances of communities and school districts.
Snyder signed the law in March.
Benton Harbor financial manager Joe Harris already has prohibited actions by city elected leaders without his authorization.
Harris is former chief financial officer for Detroit. He was appointed last year to fix Benton Harbor's troubles by then-Gov. Jennifer Granholm.
