Sen. John McCain went after President Trump’s pick to lead of the Office of Management and Budget as “an impediment” to serving troops and rebuilding military readiness.

McCain questioned Rep. Mick Mulvaney, R-S.C., at a hearing of the Senate Committee on Homeland Security and Governmental Affairs about a range of votes the congressman had taken to cut spending on defense. Mulvaney said that he did not remember specifics of a handful of the votes.
