The South Dakota Gaming Commission says it can't investigate allegations against the chairman of the Sisseton-Wahpeton Oyate Tribe over a firing and alleged conflicts of interest.

A worker for Dakota Nation Gaming Enterprise has said Chairman Michael Selvage Sr. fired him days after he alleged some financial irregularities at the Dakota Magic Casino in Hankinson, North Dakota.

Gaming Commission Executive Secretary Larry Eliason says his agency has no jurisdiction to investigate because it appears to be a complaint against a tribal official by a tribal member.

Dakota Nation Gaming Enterprise also owns the Dakota Sioux Casino and Hotel in Watertown and Dakota Connection Casino in Sisseton.
