An Indigenous student has sued Tacoma Public Schools for prohibiting her from wearing tribal regalia during her June high school graduation ceremony. Gracie Belle Ray, who is a member of the Central Council of the Tlingit and Haida Tribes of Alaska, accused the school district of discrimination and negligence after she was told that she couldn’t wear a sacred button blanket to receive her diploma from Lincoln High School in June, according to the lawsuit filed Dec. 18.
