(AREA) -- A federal agency has dismissed a complaint seeking to ban the use of American Indian mascots in Michigan's K-12 schools. In February, the Michigan Department of Civil Rights cited 35 Michigan school districts including the Sandusky Redskins, Port Huron Big Reds, Capac Chiefs, and Kinde North Huron Warriors for discrimination, saying their mascots reinforce stereotypes and hurt American Indian students' self-esteem and learning. But the U.S. Education Department's Office of Civil Rights denied the state's complaint last week. Federal officials say Michigan officials provided no specific examples of racial incidents or American Indian students suffering specific harm because of the reported discrimination. The state civil rights department said Monday it's disappointed by the ruling and is considering its options. Michigan's complaint to the federal government has drawn criticism from Republican lawmakers who say it was misguided and a done without input from communities.
