The Ho-Chunk Nation leader says he'll fight the state's efforts to close the poker room at the tribe's Madison casino. The state Justice Department is suing the Black River Falls-based tribe seeking an injunction to shut down the Ho-Chunk's electronic poker games. The state says the Vegas-style games are only allowed at the Ho-Chunk's other casinos, not in Madison which is limited to bingo-style games. The tribe argues the computerized poker games are legal because gamblers play against each other and not against the house, thereby making them Class II games. A Class II casino isn't regulated by the state. Tribal president Jon Greendeer says he has an opinion from the National Indian Gaming Commission that says the games are legal.
