House Speaker Paul Ryan lauded President-elect Trump's pick for his first budget director, South Carolina Rep. Mick Mulvaney, as being "the absolute right choice."
"In Congress, he has been a conservative reformer from day one, proposing solutions to fix the budget process and our regulatory system," Ryan said in a statement Saturday. "At OMB, he will lead the work he has started to improve the way government does the people's business."
Ryan, who served as chairman of the House Budget Committee from 2011 to 2015, said Mulvaney is "someone I have come to greatly respect and rely on, going back to our time serving together on the Budget Committee."
"I look forward to working with Mick in his new role, and I commend President-elect Trump on this excellent selection," the speaker concluded.
Ryan has long been one seen as one of Congress' most notable budget wonks, often using charts to make his case. In 2014, Ryan offered a 10-year plan to balance the federal budget.
The current chairman of the budget committee, Rep. Tom Price, R-Ga., has been chosen to lead Trump's Health and Human Services Department.
