White House Office of Management and Budget Director Mick Mulvaney said Friday that President Trump's short-term priority is getting Congress on a path to move on tax reform, which is why he worked with Democrats on a debt ceiling and government spending deal.

"At the very highest level, the first thing he was thinking was, 'Look, we have things to do.' We've got a hurricane still in Texas. Let's not forget about what happened in Houston. We've got a hurricane getting ready to hit Florida," Mulvaney told Fox News.

"And right after we deal with that, we want to deal with tax reform. This is and has been and remains the president's top domestic priority and he wanted to clear the decks so that we could deal with those three things, those two emergencies and tax reform," Mulvaney added. "And to the extent that he was able to sort of move those issues off to December, I think that was a great idea."

This week, Trump struck a deal with top congressional Democrats to keep the government funded and avoid a shutdown. The move was a knock at Republicans, who Trump ditched to work across the aisle.
