Senate Appropriations Chair Rusty Black

Senate Appropriations Chair Rusty Black, a Republican from Chillicothe, begins the Senate's budget debate Wednesday.

Overly optimistic predictions for revenue from the lottery and casino taxes will cost Missouri school districts $245 per pupil before the fiscal year ends in June. And state lawmakers are now building next year’s budget around other funding sources that may prove just as uncertain.

The Missouri Senate on Wednesday approved a spending plan for K-12 education that dips into money set aside for renovations on the state Capitol Building. During debate, state Sen. Rusty Black, chairman of the Senate Appropriations Committee, said he’s received no assurance from House Budget Committee Chairman Dirk Deaton that he will agree to the diversion or promises from Gov. Mike Kehoe that the spending will be approved if it is in the final budget.
