ST. PAUL (AP) - Minnesota lawmakers have passed a budget but are bracing for a likely special session.

Legislators approved the final pieces of a nearly $42 billion two-year spending plan just as midnight's deadline for the regular session hit Monday. But Gov. Mark Dayton has promised to veto an education budget he calls substandard. That would set up a special session.

Dayton's calling for additional funding for a statewide preschool program.

Republican House Speaker Kurt Daudt says he hopes the governor will reconsider his veto threat. He says he'll work with Dayton on a preschool bill in the 2016 legislative session.

The when and where of a special session is still up in the air. It's up to Dayton to call lawmakers back, but the Capitol will be off-limits later this week for months-long repairs.
