All three cited sources are reachable and support the CHAMPIONED rating for this promise (enact the American Innovation and Choice Online Act to bar self-preferencing by dominant platforms). Source 1 (klobuchar.senate.gov news release) documents Klobuchar leading the bill and the Senate Judiciary Committee's January 20, 2022 passage by 16-6; the quote "I'm proud to lead this much-needed legislation alongside Senator Grassley, Chair Durbin, and a bipartisan group of our colleagues" is verified verbatim, and the page frames the bill as advanced from committee, NOT enacted. Source 2 (June 2023) verifies the headline "Klobuchar, Grassley, Colleagues Introduce Bipartisan Legislation to Boost Competition and Rein in Big Tech" and the substance about giving small businesses/entrepreneurs a chance to compete and dominant platforms giving preference to their own products and services, confirming she led the renewed effort in the next Congress. Source 3 (Bipartisan Policy Center) corroborates Klobuchar/Grassley sponsorship, the 16-6 committee vote on January 20, and that the bill has not become law. The promise was to ENACT the bill; it was not enacted, so it is correctly NOT rated FULL. The evidence shows Klobuchar as lead author/sponsor who drove the bill through committee and reintroduced it — leading it beyond a mere vote — which matches CHAMPIONED. The rating does not overstate the evidence (it explicitly stops short of claiming enactment). Quotes are genuine and the sources document this outcome for this promise. Rating upheld.
