"Let him prove that he has paid taxes, because he hasn't."
According to CBS News, Romney responded:
"Let me also say, categorically, I have paid taxes every year — and a lot of taxes."
The media latched onto Reid's baseless comments. And as CNN's Dana Bash put it, many Republicans blame Reid for the "highly-partisan" environment Washington has become under Reid's leadership…
When Bash asked Reid if he really doesn't regret lying on the Senate floor, when some called him a "McCarthyite," he doubled down:
"Well, they can call it whatever they want. Romney didn't win, did he?"
Although Reid's comment about Romney's taxes shaped the public view of the candidate, and possibly even the outcome of the 2012 presidential election, PolitiFact called Reid's statement a complete lie. And now, of course, we know the truth.'
