The nonpartisan Congressional Budget Office confirmed the Big Bad Bill will add $3.4 trillion to the deficit and leave 10 million Americans uninsured.

The claim consists of two main components: the fiscal impact on the deficit and the effect on health insurance coverage. According to recent Congressional Budget Office (CBO) estimates, the bill in question, identified in multiple sources as a large tax and spending package signed into law in July 2025, is expected to add roughly $3. 4 trillion to the federal deficit over the coming decade.

This figure aligns with official CBO projections, which are considered nonpartisan and authoritative for budgetary analysis.cnn.comcnn.com10 million more people will be uninsured because of Trump’s mega-package, CBO... Regarding health insurance coverage, the CBO forecast indicates that approximately 10 million more Americans will be uninsured by 2034 as a consequence of this legislation, primarily due to changes affecting Medicaid and Affordable Care Act (ACA) enrollment.cnn.comcnn.com10 million more people will be uninsured because of Trump’s mega-package, CBO...yahoo.comyahoo.com10 million more people will be uninsured because of Trump’s mega-package, CBO...

While some reports mention even higher numbers of potential coverage losses when including broader populations (such as Medicaid enrollees), the specific figure of 10 million uninsured is consistent with multiple reputable news outlets citing CBO data. The term 'Big Bad Bill' is a partisan characterization and not an official name, but it does not affect the factual accuracy of the numerical claims.

Overall, both key assertions are supported by credible, recent CBO data and reporting. Minor nuances include that projections are for 2034, so effects are long-term estimates subject to change with future policy or economic conditions.
