The promise was to introduce the ELITE Vehicles Act to repeal the federal tax credits for new and used EVs and EV charging stations. Barrasso did exactly this and led it. His own Senate press release (verified verbatim) states he introduced the Eliminating Lavish Incentives to Electric (ELITE) Vehicles Act (S. 4237) and that it "repeals the $7,500 tax credit for new electric vehicles (EVs), eliminates the tax credit for purchasing used EVs, wipes out the federal investment tax credit for electric vehicle charging stations, and closes the 'leasing loophole'" — matching the promise. Congress.gov/GovTrack confirm S.4237 (118th Congress), sole primary sponsor Sen. Barrasso, introduced 05/02/2024 (the promise date), 18 cosponsors, referred to the Committee on Finance. Barrasso is the named author/lead sponsor of the 118th-Congress bill (the ELITE branding is his) and rallied cosponsors, which is genuine LEADERSHIP — authorship, not a mere vote or support — so CHAMPIONED is warranted over FULL. Caveat noted: the 119th-Congress reintroduction (S.541) is actually led by Cassidy, so that source evidences Barrasso's continued involvement rather than sole leadership; this does not change the finding on the underlying promise. The bill was referred to Finance and did not reach a floor vote, but the promise concerned introducing the bill, which Barrasso fully accomplished and led.
