( KTRS ) Missouri senators have voted to override Gov. Jay Nixon’s veto of a proposal to rein in the amount of money lawmakers aim to provide to K-12 schools.

The bill would set a cap on what lawmakers consider adequate school funding, which is used as a goal during budgeting. Planned basic aid for K-12 schools next fiscal year falls more than $400 million short of funding goals. Under the proposal, it would be about $54 million short.

Supporters say a cap will make it more feasible to meet target funding, but Nixon says it breaks a promise made to students.
