HARRISBURG (AP) – Four days remain of the state government’s 2013-14 fiscal year and budget negotiations continue. Democrats are applying pressure for a tax increase on the natural gas industry and sales of tobacco products to help fill a massive revenue shortfall and boost funding for public schools. But Senate Majority Leader Dominic Pileggi of Delaware County says there isn’t enough time to win enough support for a tax increase in the House before the new fiscal year begins on Tuesday. The alternative is finding one-time sources of revenue to fill the gap. Gov. Tom Corbett says he won’t consider a tax increase without passage of legislation to overhaul of public pension benefits.
