Reid bashed Romney with the claim, which he said came from a Republican and a Bain Capital investor, during the summer of 2012 as the former Mass. governor repeatedly refused to disclose the tax documents.
"He didn't pay taxes for 10 years! Now, do I know that that's true? Well, I'm not certain," Reid told the Huffington Post. "But obviously he can't release those tax returns. How would it look?"
Reid cheekily repeated the charge on the Senate floor by saying "the word's out."
Huntsman Sr. denied that he was the source in August of 2012.
