President Trump is mostly getting his way with cabinet choices, but may be facing a major battle over his nominee to run the Office of Management and Budget (OMB), Rep. Mick Mulvaney (R – SC), whose fiscal conservatism doesn't at all sit well with hawks looking for runaway military spending.

Part of the Tea Party wave of elections in 2010, Mulvaney has repeatedly been among a handful of Republican Congressmen who has resisted efforts to expand military spending, trying to freeze spending levels on the grounds that the US just can't afford to continue its spending surge since 9/11.

That appears to put him at odds with President Trump, who has been hyping the idea of massive increases in military spending. The Trump transition team argues that Mulvaney doesn't oppose higher military spending, so long as it is offset by cuts elsewhere and done in a fiscally responsible way.
