HARRISBURG (AP) – Gov. Tom Wolf and leaders of the Republican-controlled Legislature are working through their remaining differences as they try to produce an agreement on a roughly $42 billion budget plan that they say marshals new aid for PA’s public schools and environmental cleanups while cutting corporate taxes. Greasing the skids is a massive influx of tax money. Lawmakers are also expected to approve more money for services for the disabled, children, elderly, mental health services, and school security, including counseling. A big sticking point is the amount of aid that the Democrat governor wants for public schools.
