CHAMPIONED is upheld. All three cited sources are reachable and support genuine, sustained LEADERSHIP by Warren on the Price Gouging Prevention Act, well beyond a single vote or generic support. Source 1 (warren.senate.gov) confirms verbatim the headline "Warren, Baldwin, Casey, Schakowsky Reintroduce Legislation to Crack Down on Price Gouging by Giant Corporations" and shows Warren authoring/leading the Feb 15, 2024 reintroduction (named first, featured quote). Source 2 (warren.senate.gov, Oct 11, 2024) contains the cited long quote verbatim and documents Warren renewing the push via FTC pressure during Hurricanes Helene and Milton — sustained advocacy. Source 3 (Quiver Quantitative) confirms Warren is the primary sponsor of S.2321 (Price Gouging Prevention Act of 2025), referred to the Commerce Committee on July 17, 2025, and NOT passed. I additionally verified via GovTrack/LegiScan that Warren is the sponsor of record ("Ms. Warren introduced the bill") for the promise-date bill S.3803 (118th Congress), which died in committee without a floor vote — confirming she is the author/lead, not merely one cosponsor. IMPORTANT CAVEAT (accurate): the Act has NOT become law — S.3803 was referred to committee, never got a floor vote, and died with the 118th Congress; S.2321 remains in committee. So the literal promise to "pass" the Act is unfulfilled, but as a minority-party senator Warren led/drove the effort as fully as her position allows across two Congresses, which meets the CHAMPIONED bar (leadership without enactment) rather than FULL or merely ATTEMPTED.
