Independently reconfirmed: Rep. Marcy Kaptur (D-OH) was the primary sponsor of the Restoring Communities Left Behind Act (H.R. 816 in the 117th Congress, H.R. 837 in the 118th Congress), introduced with Rep. Rashida Tlaib. Kaptur's own House press release (kaptur.house.gov) and Center for Community Progress confirm her lead-sponsor role, the $5 billion HUD-administered grant program the bill created, and the extensive endorsement list (Habitat for Humanity, Center for Community Progress, National Community Stabilization Trust, LISC). In both Congresses the bill was Referred to the House Committee on Financial Services and never advanced to a floor vote or became law (per congress.gov records preserved in the prior researcher's Wayback citations, which I could not independently refetch because Congress.gov returns 403 to this tool and web.archive.org is blocked, but which are consistent with all other primary evidence). Kaptur actively LED/drove the effort well beyond a single supporting vote (repeat introductions, press releases, endorsement coalition-building) but the bill was not enacted, so CHAMPIONED (+0.75) is the correct fit — not FULL (never enacted), not PARTIAL (no partial passage), not merely ATTEMPTED (she was the driver, not just a yes vote). Same standard would rate a Republican lead sponsor of a two-Congress bill that stalled in committee the same way.
