FILE - In this Thursday, Jan. 10, 2013 file photo, President Barack Obama shakes hands with White House Chief of Staff Jack Lew in the East Room of the White House in Washington, after he announced that he will nominate Lew as the next Treasury Secretary. The to-do list that awaits Lew, if he becomes Treasury secretary, is daunting. If the Senate backs Lew’s nomination after a committee hearing Wednesday, Feb. 13, 2013, Lew will likely have to marshal all his strengths as a budget specialist and perhaps overcome inexperience in some areas to achieve significant success.
