(Fortune) - Lawmakers want to know who's pocketing the money taxpayers have spent to prop up AIG.
Rep. Carolyn Maloney, D-N.Y., on Wednesday demanded that Federal Reserve chief Ben Bernanke provide a full accounting of the firms that have received federal funds in their dealings with AIG (AIG, Fortune 500) since last fall's brush with bankruptcy.
The letter - which seeks to unmask the AIG trading partners that benefited from the billions of dollars the government has extended - comes a day after Bernanke expressed frustration with the firm, which has received more than $150 billion in federal help over the past six months.
"If there is a single episode in this entire 18 months that has made me more angry, I can't think of one other than AIG," Bernanke told the Senate Budget Committee Tuesday. "This was a hedge fund, basically, that was attached to a large and stable insurance company, made huge numbers of irresponsible bets - took huge losses. There was no regulatory oversight because there was a gap in the system."
