Romney to Reid: 'Put up or shut up'

On Sean Hannity's radio show, Mitt Romney just told Senate Majority Leader Harry Reid to "put up or shut up" on the unsubstantiated allegations he's made about the GOP hopeful not paying his taxes for ten years.

He called the allegations false (we'll have more on this later). And his campaign has pushed back hard all day. Some Republicans have also noted Reid doesn't release his own tax returns.

But the "put up" line was a bit surprising, since Romney is the one under fire for not releasing his returns beyond two years' worth, and only he, in this specific instance, has the documents in question that someone is asking be "put up."

UPDATE: Via Sam Stein, here's the bulk of the quote:

"Well, it's time for Harry to put up or shut up. Harry's going to have to describe who it is he spoke with because of course, that's totally and completely wrong," Romney told Hannity in a radio interview. "It's untrue, dishonest, and inaccurate. It's wrong. So I'm looking forward to have Harry reveal his sources and we'll probably find out it's the White House. Look, the Obama campaign is going to do everything in its power to try and talk about anything besides the president's record. Home prices, median American incomes, gasoline prices, 23 million underemployed or unemployed..."

In fairness to Romney, he is being accused of a pretty serious thing, and without proof being offered to back up the claim.
