The ATTEMPTED rating is well-supported and not overstated. The promise was to ENACT the Save Our Future Act — a carbon-fee bill returning revenue to families via direct checks. Two independently reachable sources confirm both halves of the outcome: (1) Schatz took the concrete legislative action within his power, and (2) the bill was never enacted, dying in committee. The PRIMARY Whitehouse Senate press release (reachable) confirms verbatim that "Senators Sheldon Whitehouse (D-RI) and Brian Schatz (D-HI) are introducing legislation to drastically drive down the harmful emissions causing climate change," that it assesses fees on large emitters, and that it returns revenue as direct checks ($800/eligible adult and $300/eligible dependent per year) — matching the promise's mechanism precisely. BillTrack50 (reachable) confirms the bill is marked "Dead" as of 01/03/2023, with the last action "Read twice and referred to the Committee on Finance" on 06/16/2021, and that it never advanced beyond its committee referral. Because Schatz actually acted (co-introduced) but the measure failed within the normal legislative process without enactment, ATTEMPTED is the correct tier — not a KEPT-tier outcome (no enactment) and not NO_OPPORTUNITY (he did have and use a chance to act). The Congress.gov citation returned HTTP 403 (a bot-block, not a content mismatch), but the one fact it supports — referral to the Committee on Finance — is independently corroborated by BillTrack50, so the rating does not depend on the unreachable source.
