Wikipedia's Marcy Kaptur article independently confirms she was the sponsor of H.R. 1489 (2011) — the Return to Prudent Banking Act — 'a bill aimed at restoring key provisions of the Glass–Steagall Act (1933) by repealing parts of the Gramm–Leach–Bliley Act (1999) and restoring the separation between commercial banking and securities trading,' with 30 co-sponsors. The promise text itself refers to 'her' bill, consistent with Kaptur being the originating and repeat sponsor across Congresses (H.R. 1489, 129, 381, 790, 2176). None reached passage — all died in committee — so this is not FULL/PARTIAL, but leading the reintroduction effort across five successive Congresses is the textbook CHAMPIONED profile. Congress.gov primary bill URLs are valid (blocked to bot fetch by 403, not invented). Confidence trimmed from 0.9 to 0.85 because I directly verified only H.R. 1489 through an independent secondary; the later reintroductions rely on the primary URLs the prior researcher cited. Under a nonpartisan standard, a Republican champion of a reintroduced-but-never-passed marquee bill over five Congresses would receive the same CHAMPIONED label.
