FILE - In this Sept. 21, 2016 file photo, Rep. Mick Mulvaney, R-S.C. speaks on Capitol Hill in Washington. Mulvaney, President-elect Donald Trump's choice to run the White House budget office, failed to pay more than $15,000 in payroll taxes for a household worker more than a decade ago, prompting the Senate's top Democrat to issue a statement saying the lapse should disqualify his nomination.

That combination in the $4.4 trillion budget plan submitted Monday to Congress steps far back from Trump's promises last year to balance the federal budget. If enacted, his plan would establish annual $1 trillion-plus deficits, a major reversal for Republicans who objected to increased spending during the Obama administration.

President Donald Trump on Friday picked budget director Mick Mulvaney to be his next chief of staff, ending a chaotic search in which several top contenders took themselves out of contention for the job.

Mulvaney's confirmation promises to accelerate work on Trump's upcoming budget plan. The South Carolina Republican brings staunchly conservative credentials to the post, though Trump has indicated he not interested in tackling popular benefit programs like Social Security and Medicare and wants a major investment in infrastructure programs like highways.
