US President Barack Obama, in an effort to rejuvenate the battered US economy, today nominated his Chief-of-Staff and budget specialist Jack Lew as the next Treasury Secretary.        

"I cannot think of a better person to continue Tim's work at Treasury than Jack Lew," Obama said, in a White House event announcing his nominations for the top cabinet jobs in his second term beginning January 20.        

"Jack knows that every number on a page, every dollar we budget, every decision we make, has to be an expression of who we wish to be as a nation," Obama said.        

 "So, I hope the Senate will confirm him as quickly as possible," Obama said.        

The 57-year-old, if confirmed by the Senate, will replace Timothy Geithner, who has announced his decision to quit the Obama Cabinet by January end.
