Donald Trump's selection of Rep. Mick Mulvaney (R-S.C) to become his budget chief could represent a major shift for the incoming administration on tackling entitlement spending.
Conservatives are hailing the pick while the left is bracing for significant budget cuts while possibly preparing for a battle over his nomination.
Government spending and the debt wasn't a top issue in the 2016 presidential race, something Mulvaney bemoaned on the House floor earlier this year. On his congressional website, Mulvaney states, "It's disappointing that the discussion about our debt has faded away in the last few years."
Unlike Mulvaney and many conservatives in Congress, Trump did not embrace massive changes to Medicare and Social Security and specifically rejected raising the retirement age for the popular programs.
