BOWLER, Wis. (AP) — Two American Indian tribes are going head-to-head in a fight over casino expansion in northern Wisconsin. The Ho-Chunk Nation runs six casinos around the state and is expanding its Wittenberg location, adding more slots, a restaurant and a hotel. The plan has angered the Stockbridge-Munsee Band of Mohicans, who run their own casino less than 20 miles away. The Stockbridge-Munsee fear the Ho-Chunk expansion will pull business from their casino, forcing them to cut services to their members.
