Joe Lieberman: Harry Reid 'Went Over The Line' On Romney's Taxes

Sen. Joe Lieberman (I-Conn.) is the latest public official to criticize Senate Majority Leader Harry Reid (D-Nev.) for his contention that Mitt Romney has not paid taxes for 10 years.

"I just thought it was uncalled for and unjustified and really not what we should expect from our political leaders," Lieberman said Monday morning on the radio show "Kilmeade & Friends." "Harry's a friend of mine, but I just think he went over the line on this one."

"One of the things I grew up with is the idea that if you're talking about somebody else, you really should be not speaking unless you know for sure," Lieberman continued. "And frankly, even if you know something bad about 'em, you shouldn't say that either. And, of course, this is not politics, but bottom line, I was very upset when I heard Senator Reid say that about Romney."

In an interview with The Huffington Post last week, Reid said that he had learned about Romney not paying taxes from an anonymous source who had invested in Bain Capital. Reid reiterated those claims on the Senate floor later in the week.

On Sunday, Republicans lashed out at the Senate majority leader for his comments. Sen. Lindsey Graham (R-S.C.) accused Reid of lying, and Republican National Committee Chairman Reince Priebus called Reid a "dirty liar." In an interview with "Fox & Friends" on Monday, Priebus said he would "triple down on [his] comments from yesterday."

In the interview with Brian Kilmeade, Lieberman also appeared to criticize Democrats for making Romney's tax returns a campaign issue.

"Obviously the Democrats are now saying, oh, Romney could end this by just putting out his tax records," Lieberman said. "Well, he's said for other reasons he doesn't want to put out all his tax returns for 10 years."
