Earlier this month, the Department of the Interior published a report on indigenous boarding schools in the U.S. These schools separated Native kids from their families, forced them to stop speaking their own languages, and often inflicted abuse in the name of "civilizing" indigenous children. The Interior Department says at one point the U-S supported at least 400 of these boarding schools across the country - including 15 here in Washington. The agency’s Federal Indian Boarding School Initiative also found at least 50 burial sites where children were left in unmarked or poorly maintained graves, and the department is still counting.
