Former president George Bush issued an apology to his son Monday for advocating the CIA's mid-'80s funding of Osama bin Laden, who at the time was resisting the Soviet invasion of Afghanistan. 'I'm sorry, son,' Bush told President George W. Bush. 'We thought it was a good idea at the time because he was part of a group fighting communism in Central Asia. We called them 'freedom fighters' back then. I know it sounds weird. You sort of had to be there.' Bush is still deliberating over whether to tell his son about the whole supporting-Saddam Hussein-against-Iran thing.
