 The White Earth Reservation is mourning the passing of Tribal Chairman Terrence Terry Tibbets. Tibbets passed away Sunday morning at the age of 60. At Sanford Medical Center in Fargo after a lengthy illness, Tibbets was elected chairman of White Earth Reservation in 2016. He represented all three districts on the reservation and all White Earth enrollees off the reservation. Out of respect for the chairman, Tibbets, all RBC offices were closed today. Visitation will be held Thursday at the Nato Wash Charter School, with funeral services being held Friday in Manoman. District 3 Representative Eugene Tibbets is vice chairman and will be taking over the chairman's duties until further notice.
