The Oglala Sioux tribe in South Dakota has told the state's governor that she's no longer welcome to access the Pine Ridge Reservation, one of the largest in the country, because she signed bills that allegedly target Keystone XL pipeline protesters.
The tribe's president, Julian Bear Runner, informed Gov. Kristi Noem of the council's unanimous decision in an open letter.
He added that if Noem did not honor the directive, "we will have no choice but to banish you."
Tribal banishment is a permanent ban from the reservation, and violations are punishable by law with fines or even jail time.
In a statement to CNN, Noem's press secretary Kristin Wileman said the announcement from the Oglala Sioux tribal leadership "is inconsistent with the interactions she has had with members of the community."
