Ho-Chunk Nation responded to Gov. Scott Walker's comments on the proposed casino, saying it remained optimistic that state departments and the governor would approve the application.
Walker has said all 11 Wisconsin tribes must agree before any new off-reservation casino is opened in the state.
Walker told the Milwaukee Journal Sentinel editorial board on Thursday that tribes must be unanimous before approving a new off-reservation casino. Walker said that is "absolutely" a "difficult wall to hurdle."
Walker's approval is required under federal law before any tribe can open an off-reservation casino.
Walker's comments are a blow to the Menominee tribe's effort since the 1990s to open an off-reservation casino in Kenosha.
The Potawatomi tribe has long been fighting the proposal for fear it would cut into business in their Milwaukee casino.
