RICHMOND, Va. -

Virginia Governor Bob McDonnell has ruled out a Medicaid expansion for the Commonwealth.

Under fire from conservatives in his own Republican party, the governor says the expansion of the federal-state health program is his prerogative, and it’s not up to a commission.

McDonnell agreed just before the legislature adjourned to let a commission assess whether daunting reforms, which are necessary to expand Medicaid, had been met.

Without it, Senate Democrats would have doomed his signature transportation funding legislation.
