OKLAHOMA CITY (AP) — The Oklahoma Indian Gaming Association suspended the membership of two Native American tribes that reached a deal with Gov. Kevin Stitt last month to increase the state's share of revenue from new casinos as other tribes remained locked in a legal dispute with the governor.

In a statement released on Thursday, the association said its governing board voted to suspend the memberships of the Red Rock, Oklahoma-based Otoe-Missouria Tribe and the Lawton-based Comanche Nation for the rest of the calendar year. They can seek reinstatement once the suspension expires.
