Independently verified via GovTrack (Congress.gov was bot-blocked but the same primary records confirm). Maxine Waters is the lead sponsor/author of the Housing Crisis Response Act in both cited Congresses: H.R.4233 'Housing Crisis Response Act of 2023' (118th), sponsor Rep. Maxine Waters [D-CA-43], introduced June 21, 2023, referred to committee and never received a vote; and H.R.6771 'Housing Crisis Response Act of 2025' (119th), sponsor Waters, introduced December 17, 2025, referred to committee (pending, not enacted). She originated and repeatedly reintroduced the legislation across two Congresses, so she actively LED and drove the effort well beyond a single supporting vote. However, the promise to 'push to enact' was not fulfilled: both versions stalled in committee with no floor vote or passage (Democrats were in the House minority both Congresses). This is a clean fit for CHAMPIONED (+0.75): led/sponsored/drove the effort, not fully enacted. Applying the same nonpartisan standard, any lead sponsor who authors and reintroduces a named bill but never advances it past committee referral earns CHAMPIONED, not FULL and not merely ATTEMPTED. Confidence 0.9: sponsorship is an unambiguous primary-record fact; the only judgment call is CHAMPIONED vs PARTIAL, and since zero of the bill was enacted, CHAMPIONED (led-but-not-landed) is correct.
