A decision from the federal government will make it harder for an Oklahoma-based Indian tribe to open a casino in Missouri. The deputy assistant secretary for Indian Affairs says a tribe wanting to build a casino would have to get the permission of the governor and attorney general. Attorney General Jay Nixon says the Modoc Tribe of Oklahoma had purchased land in Newton County Missouri contiguous to its tribal trust land in OK. Nixon says state officials were concerned that the tribe could open a casino in the state without any regulation or approval from Missouri citizens.
