Fact Check: Will 15 million Americans lose health insurance because of the One Big Beautiful Bill Act?

Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.


Claimant: Mark DeSaulnier (D)


Claim: “15 million Americans are on track to lose their healthcare” because of the One Big Beautiful Bill Act, and “5 million already have.”


Rating: MISLEADING


Explanation: The Congressional Budget Office estimated the law itself would increase the number of uninsured by about 10.9 million by 2034. The 15 million figure includes the separate expiration of Affordable Care Act premium tax credits, and there is no clear evidence that 5 million people had already lost coverage because of the law.
