Obama is showing himself to be an absolute inebriate for this. AIG have already agreed to comply with fed demands regarding bonuses for 09, however they were contractually obliged to payout these bonuses for 08. It would have cost AIG a helluva lot more in lawsuits had they not paid out the bonuses and that would have been even more tax payers' money down the tubes. AIG chairman and many other senior executives forfeited their bonuses as well as a token of good will. The bonus structure was also explicitly included in their application to the fed, which was accepted due it being contractual - what an ass he is proving to be - he's merely telling the people what they want to hear.
Some of you need to think about this logically as opposed to emotionally...
As I recall, Sarbanes-Oxley holds directors of company directly accountable for the goings on in the company. I would bet most of the directors had no clue as to how the financial instruments were working, therefore, by my reckoning they could be held legally liable, and could (and should) go to jail for their actions. For them to talk about paying bonuses to themselves and possibly pursuing a legal option, could have much longer and more far reaching negative consequences for themselves.
If they had but a tiny scrap of honour and pride, they would willingly give up those bonuses. However, I don't think you become a director of one of the biggest companies in the world by the use of honour, @ss licking and politicking is much more productive.
