In September 2017, Cassidy and Lindsey Graham introduced legislation to repeal and replace the Affordable Care Act. The "Graham–Cassidy" bill would eliminate the ACA's marketplace subsidies, repeal the ACA's Medicaid expansion, and introduce a temporary block grant that would expire in 2026. The legislation would also impose a per-enrollee cap on Medicaid funding. The Kaiser Family Foundation noted that the legislation "would fundamentally alter the current federal approach to financing health coverage for more than 80 million people who have coverage through the ACA (Medicaid expansion or marketplace) or through the traditional Medicaid program." An analysis by the Center for Budget and Policy Priorities found that the legislation "would cut federal health care funding by $299 billion relative to current law" in the year 2027 alone and estimated that it would leave 32 million more Americans without health insurance. President Donald Trump endorsed the bill.
