In March 2017, Cassidy sent a letter to one of his constituents that falsely asserted that Obamacare "allows a presidentially handpicked 'Health Choices Commissioner' to determine what coverage and treatments are available to you." Cassidy supported the Lowering Gasoline Prices to Fuel an America That Works Act of 2014 (H.R. 4899; 113th Congress), a bill to revise existing laws regarding the development of oil and gas resources on the Outer Continental Shelf. The bill is intended to increase domestic energy production and lower gas prices. He argued that the bill "would allow us to take advantage of our natural resources and expands our energy manufacturing and construction industries."

Kimmel had earlier chastised Republicans for voting to repeal the Affordable Care Act and replace it with legislation that would not ensure protection for children such as his newborn, who was born with a heart defect that required immediate surgery. 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.
