HARRISBURG — The Pennsylvania state House Republicans are following through on their threat to kill a provision written by the Senate to require Gov. Tom Corbett to seek federal approval for an expansion of Medicaid eligibility to hundreds of thousands of Pennsylvanians.

A key House committee today stripped the provision from a budget-related bill.

Corbett, a Republican, has refused to say whether he’d support or veto such a measure. The Senate approved it Sunday night, 40-10, as part of an 11th-hour effort to force the House and Corbett to support it.

Senate leaders say they negotiated the provision with Corbett’s office, vetted it with the federal government and wrote certain conditions into it to make it more amenable to Republicans.

Senators haven’t said yet how they’ll respond.
