Obama to Romney: 'You owe the American people the truth'

President Barack Obama was about a half-day late Thursday in offering his rebuttal to Republican challenger Mitt Romney after a surprising debate, saying, "If you want to be president, you owe the American people the truth."

Obama's remarks at a Colorado campaign event were a sharp contrast to his uncomfortable, low-energy appearance Wednesday night, when Romney's assertive performance was aimed at reversing his slipping stance in the polls. (AP)
