Not only isn't he apologizing, president Obama is again denouncing the actions of the Iranian government.The president today scoffed at a demand by Iran's president Mahmoud Ahmadinejad that the U.S. apologize for meddling in Iran's affairs.Instead, Obama replied that the Iranian government should 'think carefully' about the answers it owes to the protesters who've been arrested, beaten and killed.Today's remarks came after a meeting with German Chancellor Angela Merkel, another vocal critic of the Iran crackdown.
