HARRISBURG — The Pennsylvania House of Representatives has returned to Harrisburg as Gov. Tom Wolf and top Republican lawmakers were set to resume face-to-face meetings to discuss a three-week-old budget stalemate.

No major votes were expected today.

The Democratic governor and Republicans who control the Legislature are sparring over competing budget proposals. Mr. Wolf is seeking a multibillion-dollar tax increase to deliver a record funding boost to schools and wipe out a long-term deficit that’s damaged Pennsylvania’s creditworthiness.

Republicans passed a zero-tax increase budget with a smaller boost for education, but Mr. Wolf vetoed it, saying it didn’t meet his goals and used gimmickry to balance.

The stalemate has left the state government without full spending authority. That includes payments to schools and nonprofits and county agencies that help administer Pennsylvania’s social-services safety net.

During a regularly scheduled appearance at KDKA-AM radio in Pittsburgh today, Mr. Wolf said that bad state budgeting is costing taxpayers about $170 million a year.

Mr. Wolf said state government is paying a premium of about 1 percent interest on $17 billion in debt. He linked the extra borrowing cost to five credit downgrades that Pennsylvania has received in the past three years.

“This isn’t just Democrat Tom Wolf talking, this is people outside looking at us and right now we’re paying a premium of about 1 percent on our debt, that’s $17 billion,” Wolf said. “That adds up to about $170 million a year we’re all paying. It’s not going to education. It’s not going to roads and bridges. It’s going to the pockets of people who have bought our bonds because we don’t have a good budget.”

In the meantime, Republicans are complaining about a $750,000 ad campaign by an affiliate of the Washington, D.C.-based Democratic Governors Association that is targeting them in the showdown. The affiliate, America Works USA, has not disclosed the source of the money.

Mr. Wolf, a first-time officeholder who became governor in January, told KDKA-AM he believes that Republicans are probably doing “some testing of me as a new governor, which I think is designed to see if I’m really serious about standing up for what I believe and what I think the people of Pennsylvania want.”
