A federal lawsuit filed Thursday, Jan. 12, 2017, says U.S. Bureau of Indian Education schools are chronically understaffed, lack systems to provide special education and have a deficient curriculum. A coalition of advocacy groups announced the lawsuit involving Havasupai students at a northern Arizona school inside the Grand Canyon, but which could affect other BIE schools.
