CARSON CITY, Nev. (AP) — Nevada lawmakers are counting down the final week of the biennial session with a key budget issue still unresolved.

A two-year state spending plan of over $8 billion hangs in the balance as Republicans and Democrats negotiate how to implement a school voucher program in a way that both parties can agree on.

Republican leaders have said for months that their caucuses will oppose any budget that does not include the Education Savings Accounts program.

But neither side had made concessions by this weekend.

As the dealing continues, Gov. Brian Sandoval signed more than 150 bills into law.

The laws range from updating a statewide prescription drug donation initiative to protecting the rights of juvenile offenders.
