Sen. Joe Lieberman (I-Conn.) who made headlines during the 2000 campaign by denouncing vulgarity in modern entertainment, said he makes an exception for President Barack Obama's comment this week that he is looking for "ass to kick" over the BP oil spill.

Obama told NBC's Matt Lauer on the "Today" show that he has sought out the advice of experts on stopping the oil leak "because they potentially had the best answers, so I know whose ass to kick. Right? So, you know, this is not theater."

Lieberman told The Hill such a comment would not fall under the category of language that he denounced while running as Al Gore's running mate a decade ago.

"No, I think it was a genuine expression of what he feels," Lieberman said. "He's entitled to feel and say that."
