Adversarial re-check: all four sources cited by the prior rater are real, live, and say what was claimed. I independently re-fetched the govinfo PRIMARY record for S.2812 (118th Congress) and it confirms verbatim that the 'Carbon Dioxide Removal Research and Development Act of 2023' was introduced by 'Mr. Schatz (for himself, Mr. Bennet, Mr. Coons, Mr. Heinrich, Mr. Hickenlooper, Mr. Lujan, Ms. Smith, Mr. Whitehouse, and Mr. Welch)' on September 14, 2023 and 'read twice and referred to the Committee on Health, Education, Labor, and Pensions.' Schatz is the primary sponsor and namesake author, not a supporting voter. I separately confirmed via govinfo that the House companion H.R.5457, same title, same introduction date (September 14, 2023), was filed by Rep. Paul Tonko and referred to five committees, showing a coordinated bicameral push rather than a solo message bill. The AIP FYI Federal Science Bill Tracker, a live tracker that would show enactment if it had occurred, still lists the bill's status as 'Introduced in Senate' with 8 Democratic cosponsors and 0 Republicans; govinfo carries only the introduced (-is) text with no engrossed or enrolled version, so the bill was never enacted. WRI independently corroborates the substance matching the promise: more than $12 billion over ten years across nine federal agencies (DOE $6.856B, USDA $1.188B, Commerce $1.123B, NSF $1.101B, DOT $650M, DOD $393M, EPA $311M, Interior $222M, NASA $170M). I also verified the Schatz press office release dated February 25, 2026 on the bipartisan ReSCUE Oceans Act with Sen. Murkowski and Reps. Bonamici and Carter, showing continued CDR leadership, though that is a narrower marine-CDR/NOAA bill and not the promised act itself. Fairness test under a party-blind standard: authoring, naming, and introducing a bill, recruiting cosponsors, and pairing it with a House companion is squarely the CHAMPIONED tier, which the rubric defines as actively leading or sponsoring an effort 'even if not fully enacted.' FULL is wrong because there is no public law. ATTEMPTED would understate it, since that tier describes a supporting vote rather than authorship. A Republican senator with an identical record, own named bill, zero cross-party cosponsors, dead in committee, would get CHAMPIONED under the same rule, so no partisan leniency correction is warranted. Residual uncertainty: congress.gov, GovTrack, and LegiScan all returned HTTP 403, so I could not confirm whether a 119th Congress reintroduction exists; however that question cannot move the outcome, since a reintroduction would only reinforce CHAMPIONED and its absence is offset by the verified February 2026 CDR bill. Confidence held at 0.9.
