Blankfein says testimony doesn't point to wrongdoing

Goldman Sachs CEO Lloyd Blankfein told lawmakers Tuesday night he hadn't heard anything that proves his firm did something wrong leading up to the 2008 financial crisis. 

"I heard nothing today that makes me think anything went wrong," Blankfein told the Senate Permanent Subcommittee on Investigations about his company's actions. 

But he made a point to say he'd heard about transactions he didn't know about before today's hearing with Goldman Sachs executives who spent all day on Capitol Hill.
