President-elect Trump selected South Carolina Rep. Mick Mulvaney to be his first budget director Saturday morning, a nomination which would put a staunch fiscal conservative in charge of managing the federal budget and the logistics of government affairs.

“We are going to do great things for the American people with Mick Mulvaney leading the Office of Management and Budget,” Trump said in a statement. “Right now we are nearly $20 trillion in debt, but Mick is a very high-energy leader with deep convictions for how to responsibly manage our nation’s finances and save our country from drowning in red ink. With Mick at the head of OMB, my administration is going to make smart choices about America’s budget, bring new accountability to our federal government, and renew the American taxpayer’s trust in how their money is spent.”
