WASHINGTON — President Barack Obama nominated Deputy Secretary of State Jacob Lew to serve as director of the Office of Management and Budget Tuesday, charging him with putting the nation on a fiscally responsible path. "At a time when so many families are tightening their belts, he's going to make sure the government continues to tighten its own," Obama said in announcing Lew's selection at the White House. "He's going to do this while making government more efficient, more responsive to the people it serves," Obama continued. If confirmed by the Senate, Lew would assume the Cabinet-level post with the administration facing a deficit already exceeding $1 trillion for the first three quarters of the fiscal year. Current projections show unsustainably large deficits predicted for the coming decade, but the administration has not devised a plan to wrestle them under control, instead pinning its hopes on a bipartisan fiscal commission that many believe is doomed to election-year gridlock. Lew is no stranger to the job, having served as budget director for almost three years at the tail end of the Clinton administration.
