Verified. The promise was to introduce legislation stopping the outgoing (Biden) administration from selling off taxpayer-purchased border wall materials, framed as protecting the ability to secure the southern border. Hagerty did exactly this and LED it as sole author. (1) S.5542 (118th Cong.): I could not fetch congress.gov or GovTrack directly (both return HTTP 403 to automated fetchers — a bot-block, not a dead link), but the source is genuinely reachable and its every factual claim is independently corroborated: WebSearch surfaced the congress.gov page with the exact verbatim title cited, and BillTrack50 confirms Sponsor Bill Hagerty (R) with "Sponsors (1)"/none listed (= 0 cosponsors), referral to the Committee on Homeland Security and Governmental Affairs, and the "Read twice and referred" action on 12/16/2024 (dead 01/03/2025 at end of Congress). (2) The Hagerty press release is reachable and contains the cited quote verbatim, confirming he introduced the bill himself. (3) Fox News is reachable and contains the cited lede verbatim and names Hagerty. LEADERSHIP test for CHAMPIONED is met: he is the sole sponsor/author (0 cosponsors = his own initiative), not merely a voter or co-sponsor, and he amplified it via an official press release and public promotion — authorship plus championing, so CHAMPIONED holds rather than FULL/PARTIAL. Context not affecting the rating: the bill died in committee and the underlying sale was already under a mandated contract, but the promise was to introduce/champion the legislation, which he fully did.
