In August 2019, Baldwin was one of 19 senators to sign a letter to United States Secretary of the Treasury Steve Mnuchin and United States Secretary of Health and Human Services Alex Azar requesting data from the Trump administration in order to help states and Congress understand the potential consequences of the Texas v. United States Affordable Care Act lawsuit, writing that an overhaul of the present health care system would form "an enormous hole in the pocketbooks of the people we serve as well as wreck state budgets". The same month, Baldwin, three other Senate Democrats, and Bernie Sanders signed a letter to Acting FDA Commissioner Ned Sharpless in response to Novartis falsifying data as part of an attempt to gain the FDA's approval for its new gene therapy Zolgensma, writing that it was "unconscionable that a drug company would provide manipulated data to federal regulators in order to rush its product to market, reap federal perks, and charge the highest amount in American history for its medication."
