Representative Mick Mulvaney, a Republican from South Carolina and Office of Management and Budget director nominee for U.S. President Donald Trump, testifies during a Senate Governmental Affairs Committee confirmation hearing in Washington, D.C., U.S., on Tuesday, Jan. 24, 2017. Mulvaney said Tuesday the nearly $20 trillion national debt needs to be 'addressed sooner rather than later' and that he would push Trump to break his campaign promises and cut Social Security and Medicare.
