Reid has been saying this week that an investor with Romney's former company, Bain Capital, claimed that Romney didn't pay any taxes for 10 years. Reid says that's why Romney isn't releasing more than a year or two of his tax returns.

 

Reid isn't saying just who makes that claim — and the Nevada Democrat adds that he isn't certain that it's true.

 

On Thursday, Romney told radio host Sean Hannity that Reid needs to, in Romney's words, "put up or shut up." He called the claim about his taxes "untrue, dishonest, and inaccurate."
