Karl Rove, top aide to former President Bush, called Vice President Biden a "liar" and a "blowhard" on Thursday -- the sharpest words in an ongoing feud between Biden and Bush staffers. Rove was responding to Biden's claim that he had rebuked the president in an Oval Office exchange.
"I hate to say this, but he's a serial exaggerator," Rove told Fox News. "If I was being unkind I would say liar. But it is a habit he ought to drop."
Rove added: "You should not exaggerate and lie like this when you are the Vice President of the United States."
"There were few presidents who spend hours with somebody in the Oval Office, particularly with a blowhard like Joe Biden was," Rove continued.
On CNN earlier this week, Biden said President Bush once told him in the Oval Office, "'Well, Joe, I'm a leader," and Biden responded: "Mr. President, turn around and look behind you. No one is following."
Biden spokesman Jay Carney told Fox on Wednesday: "The vice president stands by his remarks."
