>Montana’s Top Prosecutor Bans Critical Race Theory Programs
Attorney General Austin Knudsen labeled critical race theory and some antiracism programs taught in schools as “discriminatory”

HELENA – Montana’s top prosecutor issued an opinion Thursday labeling critical race theory and some antiracism programs taught in schools as “discriminatory” and said they violate federal and state law.

Republican Attorney General Austin Knudsen’s decision bans the activities — which are also used for employee training — in the state. It came after Republican Superintendent of Public Instruction Elsie Arntzen requested earlier this month for Knudsen to weigh in on the issue.

Montana with the decision became the latest of several Republican – controlled states to decry critical race theory as an attempt to pit racial groups against each other and teach that certain groups are responsible for injustices of the past. Supporters of the theory say it is a way to look at how race and racism have shaped the nation.

Knudsen’s decision was slammed by the American Civil Liberties Union of Montana and the Montana Federation of Public Employees, which represents many government workers in the state, including school teachers and faculty at public universities.

The union’s president, Amanda Curtis, accused Knudsen and Arntzen of “working together to politicize school curriculum.”

ACLU of Montana executive director Caitlin Borgmann accused them of trying to “impose an alternate version of American history — one that erases the legacy of discrimination and lived experiences of Black and Brown people.”
