President Trump's budget request for fiscal year 2018 will be released next Tuesday, his budget director said Wednesday afternoon.

Mick Mulvaney, the director of the Office of Management and Budget, announced the timing of the budget roll-out in passing during an address to the Federalist Society, a conservative legal group.

"It's not for public consumption yet," Mulvaney joked, saying that he wouldn't talk further about the budget.

"I have to go home and read 4,000 pages of budget," he said in ending his appearance.

The president's budget is a request to Congress for funding government that also spells out the administration's wish list for spending and taxing. Actual spending and taxation are determined by laws passed by Congress.

In March, Mulvaney and the administration released a "skinny budget," which only outlined requested spending levels for agencies, that called for steep spending reductions at most agencies to pay for an increase in Pentagon funding.

That document steered clear of any prescriptions for overhauling the government's long-term finances.

The fuller budget is expected to indicate the administration's priorities for long-term spending, including programs like Medicare and Social Security which automatically incur spending when people qualify for benefits. On the campaign trail, Trump said that he would not cut or attempt reform of those programs, while Mulvaney was a major proponent of reforms to lower spending during his time as a congressman.

Members of Congress and tax lobbyists are also looking forward to the budget to see if the Trump administration includes any more details to its tax reform plans. To this point, it has released only a one-page outline of very broad goals.

Mulvaney sought to define "Trumponomics" at a Federalist Society event on Wednesday evening and said the enduring legacy of Trump's administration should be "three percent sustained economic growth."

"I tell people all the time that we have forgotten what it's like to live and work in a healthy American economy," Mulvaney said. "If you're here today and you're 30 years old or younger, you really have never worked in a thriving U.S. economy — you've been through a recession or sluggish recovery and that's it."

He added, "And I'm here to tell you as someone who's old enough to remember the healthy American economy, it is night and day different."

Mulvaney argued that, "If we had 3 percent economic growth for every year since the last recession, the budget would be balanced this year" but said he struggled to believe the budget could ever be balanced without such growth.

"I don't know if the country is ready to balance the budget based just upon reducing spending," he said.

Mulvaney noted he had lost 12 pounds since taking over the OMB gig because he forgot to eat so frequently when working in his new job.
