“Due to the safety of the Oyate, effective immediately, you are hereby Banished from the homelands of the Oglala Sioux Tribe!” Tribe President Frank Star Comes Out said in a Friday statement addressed to Noem. “Oyate” is a word for people or nation.

Star Comes Out accused Noem of trying to use the border issue to help get former U.S. President Donald Trump re-elected and boost her chances of becoming his running mate.

Many of those arriving at the U.S.-Mexico border are Indigenous people from places like El Salvador, Guatemala and Mexico who come “in search of jobs and a better life,” the tribal leader added.
