Treasury Secretary-designate Timothy Geithner is back in front of the Senate, his first appearance since revelations that he didn't pay $34,000 in taxes between 2001 and 2004, and he said it was "careless, and avoidable, but unintentional... I should have been more careful." The unpaid taxes were apparently due to Geithner's "freelance" work at the IMF, which did not take out money for taxes; Geithner was alerted to the oversight while the Obama transition team was vetting him last fall and he paid the taxes plus interest. At any rate, CNBC says Geithner is expected to be confirmed, "barring a major misstep at the hearing." And in his opening remarks, the day after Wall Street's big Inaugural Day egg, Geithner said, "Our test is to act with the strength, speed and care necessary to get our economy back on track."
