ST. PAUL (AP) - Governor Mark Dayton is calling a special session for Friday morning to finish up the state's budget.

The Democratic governor and House Republicans have worked for weeks to iron out disagreements over the remaining pieces of the state budget that Dayton vetoed. And discord among Senate Democrats over funding for environmental programs has put a budget deal at question.

Dayton issued a proclamation late Thursday night setting a special session to begin at 10 a.m. Friday.

But the environment budget's fate is still unclear. Senate Majority Leader Tom Bakk says he's not sure whether it has enough votes to pass.

Extra money for public schools is at the top of the special session agenda. The Legislature has until July 1 to finish before a partial government shutdown.
