Banks in need of even more bailout money.

By Edmund L. Andrews and Eric Dash / New York Times

WASHINGTON — Even before word came on Tuesday that Citigroup might split into pieces to shore up its finances, an unpleasant message was moving through Congress and President-elect Barack Obama's transition team: the banks need more taxpayer money.

In all likelihood, a lot more money.

Mr. Obama seems to know it; a week before his swearing-in, he is lobbying Congress to release the other half of the financial industry bailout fund.

Democratic leaders in Congress seem to know it, too; they are urging their rank and file to act quickly to release the rescue money. And Ben S. Bernanke, the chairman of the Federal Reserve, certainly knows it.

On Tuesday, Mr. Bernanke publicly made the case that one of the most unpopular and most scorned programs in Washington — the $700 billion bailout program — needs to pour hundreds of billions more into the very banks and financial institutions that already received federal money and caused much of the credit crisis in the first place.
