ST. PAUL, Minn. (AP) — Gov. Mark Dayton has signed four budget bills into law but is leaving tougher veto decisions for later.

The Democratic governor has already vetoed a public school funding bill he deems insufficient. He's also weighing calls to veto budgets that fund environment and agricultural programs, state government agencies and a jobs and energy bill.

But Dayton approved spending levels for health care programs, higher education and transportation on Friday. He also signed a budget for courts and public safety programs that also legalizes gun silencers. Dayton had previously promised to veto any bill with that provision.

The governor has until the end of Saturday to decide whether to veto or approve the other bills.
