Evidence

Ms. Warren introduced S.4509; it was read twice and referred to the Senate Judiciary Committee. The bill title prohibits common ownership of PBMs and pharmacies.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): Official bill text confirms Warren introduced legislation in the 119th Congress that directly matches the commitment, including a prohibition on owning both a pharmacy and a PBM or insurer and a one-year divestment requirement. The official status shown is still introduced/referred, not enacted.

Warren's office said the reintroduced PBM Act would prohibit joint ownership of PBMs and pharmacies and require divestment within one year.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): Warren publicly renewed a bipartisan, bicameral push for the Patients Before Monopolies Act with added cosponsors. This is concrete effort toward the promise, but the release describes a proposed bill rather than a delivered federal prohibition.

Public state: unverified As of unknown · legacy_unverified · . Original AI recommendation (not independently established): never. unknown A for effort

As of September 11, 2026, the federal prohibition has not been enacted. Warren did directly advance the promised policy by sponsoring/reintroducing S.4509, the Patients Before Monopolies Act, which would prohibit common ownership of PBMs and pharmacies and require divestment, but the bill remains introduced/referred to committee rather than passed into law. This is a serious legislative attempt, so the outcome is not delivered but merits an effort badge.
