New Jersey Gov. Chris Christie suggested on Wednesday that GOP presidential contender Mitt Romney release his tax returns immediately, rather than wait until April.
Christie—who endorsed Romney in early October and has campaigned for the front-runner since—refrained from directly criticizing his ally on NBC's Today, saying it's "up to him" when to release the tax returns, but that complete disclosure is "always better."
"I would say if you have tax returns to put out, you know, you should put them out sooner rather than later," Christie said.
Romney's taxes have emerged as a political target in the week leading up to the critical South Carolina primary. During Monday night's debate, Romney said he would "probably" make his tax returns public in April.
Now, the multi-millionaire candidate is on the defensive after acknowledging on Tuesday that his effective tax rate is just 15 percent—the same rate paid by billionaire investor Warren Buffett, who has criticized the tax system for being too friendly to the ultra-wealthy.
Christie also said on Today that he wants to remain governor of New Jersey, but wouldn't rule out a Romney-Christie ticket altogether.
