Here are the key spending cuts and increases in Trump's budget

The White House released more details of its federal budget proposal. It includes substantial cuts to Medicaid and other aid to the poor. Because it comes packaged with tax cuts, it assumes the economy will grow faster as a result and ultimately balance the budget by 2027. It is, however, unlikely to pass Congress as is.

As outlined in March's "skinny budget," the proposal includes significant cuts to most nondefense government agencies. The Environmental Protection Agency would be cut by 31 percent for 2018 and the State Department and related programs by 29 percent, with additional 2 percent cuts each year after. Law enforcement and homeland security spending are exceptions — the budget includes $1.6 billion for a border wall.

Changes to Medicaid and the Children's Health Insurance Program would save the federal government money, but would reduce the number of people with insurance. Medicaid savings are estimated at $610 billion over 10 years. The administration would shift some costs to the states, by setting annual limits on federal payments to each state, starting in 2020.

Phasing down the Defense Department's Overseas Contingency Operations fund, an off-budget spending account that is used to fund wars, saves some more money. The fund has been used to override spending caps passed by Congress and could be changed during any given year.

The budget includes new limits on medical malpractice lawsuits, expected to reduce the practice of "defensive medicine," saving Medicare $31 billion over 10 years. It also proposes raising about $36 billion in new federal revenue by selling off major American energy resources and infrastructure, opening up vast new areas of public land for oil and gas drilling, and redirecting state revenues that flow from oil and gas royalties back to Washington. The Postal Service would see $46 billion in cuts.

Interest payments on the federal debt are one of the federal government's biggest expenses. Under current law, the interest payments are expected to grow as deficits mount and interest rates increase. The Trump administration predicts that its cost-cutting will slow this rise.

The budget seeks to cut the Supplemental Nutrition Assistance Program, which provides food stamps, by $190 billion and the Temporary Assistance for Needy Families block grants by $15.6 billion. It also proposes $40 billion in savings by barring unauthorized immigrants from collecting the child care tax credit or the earned-income tax credit.

The Trump administration is proposing large cuts to the federal student loan program for low-income college students. The proposal eliminates federally subsidized loans, which pay students' loan interest while they are in school, saving $39 billion. The budget would also eliminate the public service loan forgiveness program for nurses, police officers and teachers. The largest savings, about $76 billion, would come from creating a single student loan repayment plan based on income.

The budget promises savings from reducing unspecified government payments through "actions to improve payment accuracy and tighten administrative controls."

The budget would tighten access to Social Security's disability program, counting $48 billion in savings from testing "new approaches to increase labor force participation." The budget does not make changes to Social Security benefits for retirees, which along with Medicare is one of the primary drivers of the nation's debt.

Cutting retirement benefits to federal workers would save $63 billion over 10 years. It would be done by reducing the cost-of-living adjustment for retirees and by gradually increasing government employees' contributions to their own retirement fund.

Trump is proposing a cap on crop insurance premium subsidies and eliminating commodity payments and crop insurance for farmers with adjusted gross income above $500,000 a year.

Trump is proposing a roughly 10 percent increase to the Pentagon's base budget, with some of the money going toward new jets for the Air Force and ships for the Navy. The increase goes hand in hand with Trump's proposal to cut foreign aid, including programs that military officials say contribute to global stability and are seen as important in avoiding future conflicts.

The $1 trillion infrastructure program is now called a private/public infrastructure investment, priced at $200 billion over 10 years.

The budget would extend a voucherlike program that allows veterans to seek medical care in private hospitals outside the Veterans Affairs system.

A new program would provide six weeks of paid leave to new parents.

The bulk of the savings in Trump's budget come from "economic feedback" effects. The administration is projecting that its tax cuts and changes to welfare programs will spur significant economic growth and expand the workforce, resulting in $2 trillion more in revenue than would have been generated under current law. The economy would need to grow at least 3 percent per year, a pace most economists say is unrealistic.
