President Obama has imperiled his second term by lying to the American people, one of the nations foremost lying experts said Sunday on NBCs Meet the Press. The accusation carried weight, observers said, coming as it did from a legendary figure in the high-stakes world of competitive lying. He was harshly critical of Mr. Obamas fibbing, calling it amateurish at best, contrasting the Presidents lack of lying experience with his own half-century of dishonesty. The American people deserve a President who is a world-class liar, he said. Sadly, they do not have that President. Speaking from experience, he said that he had learned the hard way just how difficult lying can be: Just when you think youve gotten away with it, theres someone with a hidden camera catching you telling the truth. He said that it was possible that the President might grow as a liar in the remaining three years of his term, but he was not optimistic. Lying isnt something you can just pick up on the job, he said. Maybe President Obama would be better off leaving it to us professionals.
