RICHMOND, Va. (AP) — Gov. Bob McDonnell has amended the transportation funding reform bill that stands as his signature legislative achievement, extending regional taxing authority beyond Virginia’s urban areas to other areas statewide in an effort to satisfy concerns about its constitutionality.

The Republican governor also amended other 2013 General Assembly bills to prohibit abortion coverage through the federal healthcare exchange that will serve Virginia and clarify requirements for expanding Medicaid in Virginia.
