The fate of the Michigan bill, which has no Democratic sponsors, is unclear. While Republicans control both chambers of the state legislature, the governor, Gretchen Whitmer, is a Democrat. Her office did not immediately respond to a request for comment about the bill.
The bill hammers another wedge into a national schism over race in America. That divide widened in recent months after the on-camera killings of George Floyd, Daunte Wright, and Adam Toledo by police, which sparked protests and prompted more Americans to recognize that people of color face more barriers in the U.S. than white people.
Even as lawmakers in some parts of the country pushed schools to talk more about the history of race in America, numerous Republican-led states, borrowing language from former President Donald Trump, are attempting to limit those discussions.
