Congressional budget measures under the Trump administration brought significant plans aimed at reducing the federal share of Medicaid funding and restructuring the program. The “One Big Beautiful Bill Act,” signed into law in 2025, forecasts to reduce federal Medicaid expenditures by more than $1 trillion over a decade and adds new requirements, like work obligations and higher cost-sharing, which could impact coverage and reduce federal support.
