In South Dakota, the Cheyenne River Sioux Tribe is defying orders by Governor Kristi Noem to remove COVID-19 checkpoints. The checkpoints are set up on highways on tribal land, which Kristi Noem says is illegal. Cheyenne River Sioux Chairman Harold Frazier says the checkpoints are the best way to protect against COVID-19 entering the community, which is not equipped to handle an outbreak. South Dakota has also ordered the Oglala Sioux Tribe to remove its coronavirus checkpoints. Indigenous activists say the standoff in South Dakota could have major implications for other battles on tribal land, including the fight to stop the Keystone XL pipeline.
