WICHITA, Kan. (AP) — The specter of a possible furlough of state government workers is affecting the lawsuit filed by Kansas against an Oklahoma tribe over a proposed casino. Kansas sued the Quapaw tribe to keep it from expanding its casino into southeastern Kansas, arguing it would harm that state's current efforts to build its own casino in the area. Also named as a defendant is the U.S. Department of Interior. But Kansas Attorney General Derek Schmidt has now asked the court to extend next week's looming deadline to answer a Justice Department motion seeking to dismiss the state's lawsuit. The state told the court in a filing Tuesday it needs more time to conduct extensive legal research and says its attorneys face a possible work furlough due to legislative conflict over the budget.
