Independently verified. The actionable pledge -- give Medicare the power to negotiate drug prices -- was fully delivered. Biden championed and signed the Inflation Reduction Act of 2022 (P.L. 117-169), which amended the Medicare 'non-interference' clause to REQUIRE HHS to negotiate prices, and the administration then exercised that power: CMS announced negotiated prices for the first 10 Part D drugs on Aug 15, 2024 (38-79% below list, ~$6B projected Medicare savings), effective 2026. All three prior sources check out as real and live and directly support the claim: the White House fact sheet states verbatim 'Medicare has the power to negotiate prescription drug prices for the first time in history thanks to the Inflation Reduction Act'; KFF confirms the IRA 'amends the non-interference clause by adding an exception that requires the Secretary of HHS to negotiate prices'; GAO GAO-25-106996 documents implementation. Adversarial fairness check: I applied the same standard I would to either party -- a politician who campaigns on X, drives and signs the landmark law enacting X, and whose administration then implements X, has kept the promise; the opposite party with this record would earn FULL too. Confidence trimmed slightly from 0.97 to 0.95 only to acknowledge the KFF caveat that negotiation currently reaches a limited set of high-cost drugs (not all drugs), but the promise text asks only to 'give Medicare the power to negotiate,' which unambiguously now exists where it was previously prohibited. The 'preserving and defending Medicare' framing was also honored (no benefit cuts). FULL stands.
