The promise is an advocacy/leadership commitment: introduce the Federal Reserve Board Abolition Act and champion abolishing the Fed. All three cited sources were fetched, are reachable, and support the CHAMPIONED outcome. (1) GovInfo (PRIMARY) confirms S. 4463, short title "Federal Reserve Board Abolition Act," full title "To abolish the Board of Governors of the Federal Reserve System... to repeal the Federal Reserve Act," Sponsor Mike Lee (UT), introduced June 5, 2024 (promise dated 2024-06-06), referred to the Committee on Banking, Housing, and Urban Affairs; the action line "Mr. Lee introduced the following bill" establishes Lee as author and lead sponsor — genuine leadership, not a vote or mere support, which satisfies the CHAMPIONED bar. (2) Deseret News confirms verbatim that Lee, with Rep. Thomas Massie, re-introduced the same Act in March 2025 (119th Congress), sustaining the effort into a new Congress, and that it was unclear if it would ever reach the floor. (3) TownLift confirms verbatim Lee's press statement that the legislation targets "a system that enables unchecked government spending, the monetization of federal debt that fuels it, and widespread economic disruption. It's time to end the Fed," directly supporting the promise's "which he argues enables unchecked government spending" framing. The quotes are genuine, not fabricated. CHAMPIONED does not overstate the evidence: the rating correctly does not claim the Fed was actually abolished (it still exists — so not FULL abolition), only that Lee authored, sponsored, publicly drove, and persisted with the introduction/advocacy effort across two Congresses. That documented leadership exceeds the single-vote CHAMPIONED threshold. Not UNRATABLE: post-promise conduct is well documented in primary and reputable secondary sources.
