WASHINGTON — President Donald Trump sends Congress a proposed budget this week that will sharply test Republicans' ability to keep long-standing promises to bolster the military, making politically painful cuts to a lengthy list of popular domestic programs.
The Republican president will ask his adopted political party, which runs Capitol Hill, to cut domestic agencies such as the Environmental Protection Agency and the departments of Education and Housing and Urban Development, along with grants to state and local governments and community development projects. The spending plan, set for release Thursday, would make the Pentagon the big winner with a $54 billion boost to defense spending.
Trump has promised to "do a lot more with less," but his blueprint faces a reality test with Republicans, many of whom are already protesting.
Republicans have groused about some of the preliminary plans, including elimination of the $3 billion community development block grant program that's popular among local GOP officials, a 25 percent cut to the EPA and elimination of 3,000 jobs, and essentially scuttling a $300 million per-year program to clean up the Great Lakes.
Sen. Rob Portman, R-Ohio, is joining with Democrats to push back on that last proposed reduction. Cuts to the Coast Guard are meeting Republican resistance. Trump's plan to eliminate community development block grants was dismissed on Capitol Hill by those who remember how a modest cut to the program sank a spending bill not long ago.
"The money has to come from someplace," White House budget chief Mick Mulvaney said on the "Hugh Hewitt Show." ''The question is this: What's more important? What's more important — defending the border, defending the country or doing those things?"
Democrats are unlikely to support the cuts, and Republican defections raise the possibility of a congressional train wreck and a potential government shutdown when the 2018 budget year begins Oct. 1.
Preliminary reports on the budget show some domestic Cabinet agencies, such as the departments of Homeland Security and Veterans Affairs, would see increases, including $3 billion for Trump's promised wall on the U.S.-Mexico border. Trump said repeatedly during the campaign that Mexico would pay for that project, but Mexico has said no.
Those intended spending increases, however, would mean deeper cuts elsewhere.
People familiar with the budget who spoke on condition of anonymity in advance of the public release say the White House is seeking a 30 percent cut from an Energy Department office that promotes energy efficiency and renewable energy. The office has funded research on projects such as LED light bulbs, electric trucks, advanced batteries and biofuels.
The Office of Energy Efficiency and Renewable Energy is targeted for at least $700 million in cuts from its current $2.1 billion budget, said Scott Sklar, chairman of the steering committee of the Sustainable Energy Coalition.
The Energy Department could see steep cuts for its 17 national laboratories, which conduct cutting-edge research on topics from nuclear power to advanced materials for energy generation, storage and use.
Trump's preliminary budget, delivered in secret to agencies last month, proposes a 37 percent cut to the State Department and foreign aid budgets. Those cuts and others were subject to revision in the back and forth that the White House had with agencies leading up to the coming release this week.
Trump's submission won't tell the complete story. It will be limited to the discretionary, $1 trillion-plus portion of the $4 trillion annual federal budget that pays for Cabinet agencies and departments.
These annually appropriated programs have been squeezed in recent years while the costs of mandatory programs such as Medicare and Social Security have risen each year, mostly unchecked.
The remainder of Trump's budget — proposals on taxes, mandatory spending and deficits and projections on the economy — won't come out until May. That document is sure to upset members of the GOP's once-proud and large band of deficit hawks, because Trump's full plans are sure to show large, permanent budget deficits, even with all of the tricks and tools available to the White House Budget office.
The government ran a $587 billion deficit last year that required it to borrow 15 cents of every dollar it spent. Looking ahead, the nonpartisan Congressional Budget Office says the government is on track for accumulated deficits of more than $9 trillion over the coming decade.
CBO Director Keith Hall warns that such huge deficits are putting the government on a long-term path that "would have serious negative consequences for the budget and the nation, including an increased risk of fiscal crisis."
But Trump is promising to leave the government's two largest programs, Medicare and Social Security, virtually untouched. He's also promising $1 trillion in infrastructure spending, even as pressure is building to finance tax cuts with borrowed money.
Trump's budget options are already being hemmed in by decisions on health care. The Trump-endorsed House bill cuts taxes by $1 trillion over the coming decade while devoting hundreds of billions of dollars in Medicaid cuts toward a new GOP subsidy.
"They're going to have a hell of a hard time passing a budget that balances — even fabricating a budget that balances," said Kentucky Rep. John Yarmuth, the top Democrat on the House Budget committee. "This health care bill is going to make their budget very tricky."
