White House officials are crafting a fiscal 2018 budget proposal for President Donald Trump that aims to wipe out the deficit through a combination of robust economic growth, steep cuts in certain means-tested entitlement programs and other savings.

Trump would aim to balance the federal budget within 10 years. His plan relies on Congress passing a comprehensive tax overhaul and other policies, such as deregulation. The administration believes these approaches will jump-start the economy, causing economic growth to ramp up to 3 percent in the coming decade, people with knowledge of the plan said.

While the Trump budget request is not final and could be changed, these sources also said it would propose about $800 billion in cuts to projected spending in a wide array of means-tested, mandatory spending programs including Medicaid over 10 years. The proposed reductions in Medicaid would go beyond those in a House-passed health care overhaul.

Trump is not expected to propose any major changes in Social Security or Medicare. He pledged not to cut these programs during the campaign. But sources said the budget will include proposals to reduce the cost of the Social Security Disability Insurance program, which is not means-tested.

It’s not clear which programs might be cut beyond Medicaid but means-tested mandatory spending programs include food stamps, Temporary Assistance for Needy Families, Supplemental Security Income, child nutrition programs and the Pell Grant program.
