HARRISBURG — Gov. Tom Wolf blasted Republican lawmakers Monday over a plan to force piece-by-piece override votes of his budget bill veto, saying GOP leaders cannot negotiate in good faith while staging what the Democrat called an unconstitutional and unproductive move.

Wolf’s comments in a letter to lawmakers came a day before today’s planned veto override votes and the resumption of talks on an eight-week-old budget stalemate that has shut off funding to schools and a range of safety-net services.

The House Republican plan could pose a political dilemma to Democratic lawmakers. Supporting Wolf’s veto would mean taking a series of votes against funding for educational and human services programs they actually support.

“We cannot afford the delay that will occur with an unconstitutional veto attempt,” Wolf wrote. “Republican leadership cannot negotiate in good faith to move our Commonwealth forward while at the same time leveling public ultimatums and undertaking unconstitutional measures like this.”

Democrats have vowed to oppose the line-by-line veto override attempts to prevent Republicans from achieving the necessary two-thirds majority. Republicans rebuffed accusations their plan is a political stunt and insisted nothing in case law or the constitution outlaws a veto override that targets a piece of the budget, rather than the whole vetoed bill.

“The Democrats not wanting to vote to send money to these countless organizations caught in the middle of the stalemate is offensive,” House Republican leaders wrote.

Pennsylvania is nearly two months into its new fiscal year without the new year’s spending plan. On June 30, Wolf vetoed the GOP’s entire $30.2 billion, no-new-taxes budget bill within hours of its passage with only Republican support.
