A high school in Fairfax County, Virginia, reportedly painted the historical account of Christopher Columbus as “mythology” in classroom instruction while highlighting examples of racism against Native Americans, including sports mascots.

The lecture materials from Langley High School in northern Virginia were first revealed by activist and journalist Asra Nomani in an op-ed for the Federalist, which wrote that the materials were used in a lecture to students last Tuesday as a primer for Indigenous People’s Day.
