On or before the first. Monday in February, the president submits a detailed budget request for discretionary spending to Congress, covering the next fiscal year that begins October 1.
The president's proposed budget that was given to Congress only addresses Discretionary spending for the 12 agencies. The other 92% of the Federal Government's expenses are mandatory or entitlements.
President Trumph's $3.6 Trillion in Revenues (FY 2017) must cover all discretionary, mandatory, and entitlement spending requirements.
The president’s proposed $1.15 Trillion discretionary budget for FY 2017, includes increases for only three agencies — Veterans Affairs +6%, Homeland Security +7%, and Defense +10%. Defense spending accounts for 56.1% of all total discretionary spending.
The budget makes severe cuts to Health and Human Services that includes $5.9 Billion or about 18% to the National Institutes of Health (NIH). The proposed budget jeopardizes essential biomedical research and development by NIH. It also impacts coherent prevention strategies and critical disease response work by the Centers for Disease Control and Prevention (CDC).
