Contradicting Views On Mitt Romney's Tax Returns

... from a couple of Republicans?

South Carolina Governor Nikki Haley thinks that calls for Romney's tax records are a 'distraction':
South Carolina Gov. Nikki Haley told The Daily Caller that Texas Gov. Rick Perry challenging former Massachusetts Gov. Mitt Romney to release his tax returns is a “distraction” and “nothing but a political ploy.”

“I think those are distractions. I saw it in my race. They always say ‘show me your tax return’ just so they can start throwing holes in it. I think that will be his decision to make, but that’s nothing but a political ploy,” Haley told TheDC in the spin room of the GOP presidential debate. Gov. Haley, a tea party favorite, has endorsed Romney for president.
New Jersey Governor Chris Christie seems to think otherwise (sorry about the ad):

Both of these Republican governors have endorsed Mitt Romney for the GOP nomination -- and have made appearances with him. My guess is that one of them needs to check their list of talking-points.
