Washington, Apr. 10: Republican strategist Karl Rove has called Vice President Joe Biden a "liar" for claiming that he scolded former President George W Bush in private meetings.
"I hate to say this, but he''s a serial exaggerator. If I was being unkind, I would say liar. But it is a habit he ought to drop," Fox News quoted Rove, as saying.
"You should not exaggerate and lie like this when you are the Vice President of the United States," he added.
