Treasury Secretary Timothy Geithner on Wednesday notified Congress that the U.S. is going to hit the debt ceiling on New Year's Eve.

"I am writing to inform you that the statutory debt limit will be reached on December 31, 2012," he wrote in a letter to Congress, "and to notify you that the Treasury Department will shortly begin taking certain extraordinary measures authorized by law to temporarily postpone the date that the United States would otherwise default on its legal obligations."
