HARRISBURG — Gov. Tom Corbett and top Republican state lawmakers closeted themselves in private meetings Wednesday in an attempt to sort out their remaining differences on a state budget ahead of the June 30 end of the state’s fiscal year.

They gave little detail about what, if any, progress they made.

Morning and evening meetings in the Republican governor’s offices broke up without negotiators announcing any agreement or revealing where their differences remain in a spending plan that is expected to tally about 3 percent less than this year’s budget and deliver deep cuts to spending on education.

“I feel confident that we’ll have a budget done on time,” Corbett said after emerging from Wednesday evening’s hour-plus meeting.

The meetings were held on the eve of what Senate Majority Leader Dominic Pileggi, R-Delaware, said is the deadline to get a handshake agreement in time to write bills and hold votes to enact a budget before the new budget year starts July 1.

After a Wednesday morning meeting, he warned that time was ticking down.

“We reminded everyone that certainly, looking at the calendar, that the time for legislation is tightening, so it introduces a certain increased level of urgency,” Pileggi said. “Bills need to be drafted. They need to be moved. There needs to be floor action. There needs to be committee action. ... (A handshake agreement) really needs to happen by tomorrow.”

Corbett and his fellow Republicans who control the Legislature have repeatedly said they are focused on producing a budget that spends less than this year’s, does not raise taxes and is signed before July 1.
