Romney to Reid: "Put Up or Shut Up"

Mitt Romney has a message for Harry Reid: "put up or shut up."

The Senate Majority Leader twice this week has repeated a wildly speculative rumor, that Mitt Romney did not pay any taxes for 10 years.

"The word's out that he hasn't paid any taxes for ten years," Sen. Reid, D-Nev., said of Romney on the Senate floor Thursday. "Let him prove that he has paid taxes, because he hasn't."
