White House Office of Management and Budget Director Mick Mulvaney

President Trump's Director of the Office of Management and Budget Mick Mulvaney on Sunday defended the administration's budget blueprint for not reducing the federal deficit — despite his past reputation as a deficit hawk member of Congress.

"Keep in mind, the administration is different than members of the Hill, the members of the House and the Senate," Mulvaney told host Chuck Todd on "Meet The Press."
