HARRISBURG — Legislation to substantially expand taxpayer support for private and religious schools in Pennsylvania won passage Tuesday in the Republican-controlled Legislature, although Gov. Tom Wolf is signaling that he will block it.

The vote ramps up a fight between supporters of public and private schools in the thick of negotiations between Republican lawmakers and the Democratic governor over a roughly $34 billion budget package.

The bill passed the state Senate on a party-line basis Tuesday, a month after it passed the Republican-controlled House on near-party lines.

Wolf said he would look at the legislation.

“What I’ve heard doesn’t sound real good,” Wolf said.

Republicans, Wolf said, haven’t explained how they would finance the $100 million cost of the bill, and he criticized tax credits programs as lacking control or accountability.

“It seems to me to be at odds with that need of a government in a democracy like ours to support broad-based, accessible public education,” Wolf said.

The bill is sponsored by House Speaker Mike Turzai, R-Allegheny.

The existing $110 million Educational Improvement Tax Credit program effectively lets corporations direct tens of millions in tax dollars to favored private and religious schools.

Sen. Sharif Street, D-Philadelphia, called the bill “irresponsible legislation both morally and fiscally” and said the state should use the money to boost aid to cash-strapped districts where property taxes are high.
