Russ Vought, acting director of the White House Office of Management and Budget, said in a statement the proposal "embodies fiscal responsibility" and "shows that we can return to fiscal sanity without halting our economic resurgence".
The Democratic chair of the House budget committee, John Yarmuth of Kentucky, called proposed cuts to essential services "dangerous" and said Trump had already added almost $2tn to deficits with "tax cuts for the wealthy and large corporations, and now it appears his budget asks the American people to pay the price".
The request, which is to be unveiled Monday, would far exceed the 5.7 billion US dollars Trump demanded past year, which led to an impasse that resulted in a 35-day partial shutdown of the USA government, the longest ever.
"I don't think good growth policies have to obsess, necessarily, about the budget deficits and so forth", Kudlow said on "Fox News Sunday".
The fiscal 2020 proposal sees the deficit expanding to $1.1 trillion for 2019 and 2020, when Trump will run for re-election.
Over the weekend, the President took to Twitter to defend his performance on the border wall, which many of his 2016 supporters felt was a cornerstone of his campaign, and lash out at his most vocal critics.
It also aims to slash total non-military discretionary spending by 9 percent, but even with those cuts the budget would not balance in 10 years-the window within which presidents typically try to balance their spending plans, even if not realistically.
Maryland Democrat Steny Hoyer, a House rep since 1981, said the budget reflected the administration's "separation from reality". Some of that new spending-$506 million of it, to be precise-would be used to hire an estimated 2,800 additional law enforcement officers and critical support personnel at U.S. Customs and Border Protection and U.S. Immigration and Customs Enforcement.
"I would actually push back on that assessment", Thompson said when asked about what a moderator called "Trump's expressed disinterest in extending New START". "We're going to do our own (spending) caps this year and I think it's long overdue".
President Trump is releasing a $4.7 trillion budget plan Monday that stands as a sharp challenge to Congress and the Democrats trying to unseat him, the first act in a multi-front struggle that could consume Washington for the next 18 months.
The new budget will again put pressure on the Democrats, who control the House and are certain to resist the funding request. Many Democratic leaders have said they will oppose the sweep of the White House's proposed budget cuts, though White House officials have signalled they plan to fight over the budget much harder this year, believing it provides a sharp contrast between Democrats and Republicans heading into the final year of Trump's first term. Lawmakers have previously rebuffed Trump's calls to cut funding for federal environmental and transportation programs - just as they ignored many of President Barack Obama's spending priorities.
He will request another $3.6 billion for the Defence Department's military construction budget to erect more sections of a wall. "The same thing will repeat itself if he tries this again", the statement continued.
Other ideas, however, are more likely to gain traction - like the administration's request for almost $300 million to combat HIV/AIDS and lower new transmissions of the disease by 90 percent within a decade. It also would eliminate funding for Medicaid expansion under the Affordable Care Act has gone to about three dozen states over the past five years.
Despite active work on a bipartisan deal, the president declared a national emergency in February to secure the funding his administration felt was necessary to build barriers along the southern border.
While the House has voted to revoke the emergency and the Senate may have enough votes to hold up the measure, neither chamber has enough votes to override an assumed veto by Trump.
