Rating upheld as FULL. The promise was to co-introduce a constitutional Balanced Budget Amendment and commit to supporting a federal balanced-budget requirement. All three cited sources support this outcome, and the load-bearing quotes verify. Source 1 (crapo.senate.gov, PRIMARY, Feb 3, 2021): Verified directly via WebFetch. The cited quote appears verbatim — Crapo and Risch joined Hyde-Smith and 12 additional co-sponsors in introducing a balanced budget amendment requiring annual balanced budgets. This documents the exact co-introduction action promised. Source 2 (hydesmith.senate.gov, PRIMARY): Verified directly via WebFetch. This is the Feb 10, 2023 reintroduction (S.J.Res.13, 118th Congress). The cited quote appears and Risch is named as an original cosponsor — corroborating that he sustained the position across Congresses. Source 3 (congress.gov S.J.Res.6 cosponsors, PRIMARY): Direct WebFetch returned HTTP 403 (congress.gov blocks automated fetches), so I corroborated independently via WebSearch. The bill title is confirmed verbatim ("A joint resolution proposing an amendment to the Constitution of the United States relative to balancing the budget") and the introduced-by list explicitly includes "Mr. Risch." The cited quote's substance is confirmed accurate. FULL is not overstated: co-sponsoring the amendment was an action within Risch's control that he completed on 2021-02-03 and repeated in 2023. FULL rather than CHAMPIONED is correct because Hyde-Smith was the lead sponsor, not Risch. The rationale correctly acknowledges the resolution never received a floor vote while noting the promise concerned the co-introduction itself. No fabrication, no unreachable-source failure of substance (the one 403 was independently confirmed).
