Obama says he's not offended by slur on his name

Sen. Barack Obama said Sunday he was not greatly offended by the Fox News chief's word play about his name that led Nevada Democrats to cancel a presidential debate hosted with the network. Fox's Roger Ailes made a remark last week about the similarities between the Illinois senator's name and al-Qaida leader Osama Bin Laden. "I didn't take great offense at the joke," Obama said in an Associated Press interview while campaigning in Iowa. "I have been called worse."
