E-mails among in-house lawyers at the Federal Reserve Bank of New York show they worked feverishly in early January 2009 to find a way to keep secret the details behind American International Group, Inc.‘s $60 billion in payments to counterparties in risky credit default swaps. And, the e-mails show, the lawyers weren’t trying to hide the details just from the public but also from Congress.

A Fed spokesman was not immediately available for comment.
