AIG executives shouldn't kill themselves, but they should take more responsibility for their company's failures than they have to date, Sen.

Grassley explained his remarks Monday in which he suggested that AIG executives should either resign or commit suicide.

"Of course I don't want anybody to go commit suicide, but I do want some contrition -- I want showing of remorse," Grassley said Tuesday during an appearance on Bloomberg News. "I have not heard a single apology from a single Wall Street CEO...for how they've run their company or financial institution."

"And in the case of the Japanese, they do one of two things: they either go commit suicide or they take a deep bow and say apologies and then sometimes resign," Grassley added. "But they take full responsibility, and we're not hearing that. And obviously I don't want anyone to kill themselves, because I don't believe in that sort of thing. But you ought to say, 'I'm sorry.'"

Grassley's remarks were perhaps the most outrageous of those expressed by members of Congress and the Obama administration on Monday after all parties in Washington piled on AIG for handing out millions in bonuses to employees and executives while receiving some of the largest financial assistance from the federal government.
