Virginia Gov. Bob McDonnell defended Republican presidential contender Mitt Romney’s record on health care Friday morning as he amps up his support of the former Massachusetts governor in a tightening race.

McDonnell was on Fox News to dissect Romney’s Thursday night debate performance, including a testy back-and-forth with former Sen. Rick Santorum on President Obama’s health care reforms. Santorum questioned whether Romney would repeal Obama’s signature legislative achievement considering Romney approved similar reforms in Massachusetts while leading the state.
