U.S. Sen. Rand Paul lobbed the latest volley in a war of words against fellow Republican -- and possible 2016 GOP presidential rival -- Chris Christie, saying the New Jersey governor's decision to expand Medicaid was "very expensive and not fiscally conservative."
CNN reported that although Paul
, of Kentucky, conceded that no "one person gets to decide what is and what isn't conservative," he said Christie's acceptance of a portion of President Barack Obama's Affordable Care Act last February suggests Christie isn't a true conservative.
"On the case of the New Jersey governor, I think embracing Obamacare [and] expanding Medicaid in his state is very expensive and not fiscally conservative -- and really, many Republican governors who I would say are conservative did resist expanding and accepting Obamacare in their states," Paul said on CNN's Erin Burnett OutFront.
"That fact, I would say, would lead toward you making the conclusion that it's not a very conservative proposal."
Christie was among eight Republican governors to accept the expansion of Medicaid included in Obamacare, saying he was "no fan of the Affordable Care Act" but that the move was "the smart thing to do for our fiscal and public health."
In June 2012, the U.S. Supreme Court upheld the individual mandate of Obama's sweeping healthcare law and the Medicaid expansion, though it allowed states to choose whether to participate in the expansion program.
Paul's questioning of Christie's conservative chops hasn't let up over the past couple of weeks.
Earlier this month, Paul labeled Christie a moderate
and then slammed him for appearing in television ads funded by taxpayers
after Superstorm Sandy.
Christie handily won re-election earlier this month in historically blue New Jersey.
After criticism from members of his own party, such as Paul and Sen. Marco Rubio, R-Fl., Christie said he doesn't feel he has any "fence-mending" to do with the GOP.
"I don't feel like I have any fence-mending to do," he said Monday at the Wall Street Journal CEO Council
. "I'm going to be me."
