Goldman Sachs today agreed to pay $550 million to settle federal claims that it misled investors about the subprime housing market. If approved by a judge, it would be the largest settlement in SEC history. But critics call it a drop in the bucket for a banking giant that reported more than $13 billion in profits last year. In fact, news of the settlement pushed Goldman shares up 5 percent — adding more to the value of the firm than the settlement amount. So tonight, we ask: Is this record settlement enough? Or did Goldman — and boss Lloyd Blankfein, pictured above — get off easy? Tell us what you think. Embedded is a previous "Nightline" report about the banking giant.
