All four cited sources are reachable and support the CHAMPIONED outcome for this promise. The two PRIMARY Wyden sources confirm (a) Wyden authored and introduced the Government Surveillance Reform Act to reform FISA Section 702, restore warrant protections, and close the data-broker loophole — the exact cited headline ("Wyden, Lee, Davidson and Lofgren Introduce Bill to Reform FISA Section 702...") appears verbatim and names Wyden first as lead introducer — and (b) his April 20, 2024 statement opposing 702 reauthorization without warrant reforms, with the cited quote appearing verbatim. CyberScoop (secondary) confirms Wyden introducing/leading the reform bill and its exact headline; the ACLU (secondary) confirms the exact title and names Wyden as the bill's lead sponsor. These sources demonstrate real LEADERSHIP (authored/introduced/led the bipartisan-bicameral vehicle), not a mere vote or expression of support, which distinguishes CHAMPIONED from FULL/PARTIAL. The substantive reform was NOT enacted — Section 702 was reauthorized without the warrant requirement — so the promised outcome was not achieved and FULL is not warranted; CHAMPIONED (sustained leadership of the promised vehicle without achieving enactment) is accurate and not overstated. Minor note: the fetched Wyden introduction press release reads as the updated 2026 reintroduction rather than the original Nov. 2023 introduction, but this only reinforces the rating's claim of leadership sustained across Congresses; the original 2023 introduction is independently documented by the CyberScoop source. Rating upheld.
