HARRISBURG, Pa. (AP) — U.S. Sen. Pat Toomey is wading into a budget fight in Pennsylvania over substantially expanding state taxpayer support for private and religious schools that is stoking pushback from public school advocates. Democratic Gov. Tom Wolf is expected to veto the measure, but Toomey, a Republican, wrote to the governor on Monday to urge him to sign it and make the case for nearly doubling a tax credit program, increasing it by $100 million to $210 million a year.
