Megyn Kelly tonight clashed with radio host Richard Fowler over Harry Reid’s 2012 claim that Mitt Romney hadn’t paid his taxes in 12 years.

CNN’s Dana Bash asked the former Senate majority leader if he regretted his Romney remark, adding that “people have even called it McCarthyite.”

“Well, they can call it whatever they want,” Reid said. “Romney didn’t win, did he?”

Fowler told Kelly that the Senate majority leader’s job is to vehemently defend his party.

“By lying?” Kelly questioned, remarking that Reid is “proud he told a lie.”

“Richard, this is wrong, this is wrong, and you know it’s wrong, don’t you?” she asked.

“I just think it's politics at its finest,” Fowler said, arguing that it’s the job of politicians to evade the truth.

Fowler said that Reid isn’t the only politician who has fabricated things, but Kelly said that doesn’t excuse it.
