All three cited PRIMARY sources are reachable, and every quoted line appears verbatim. The 2021 release headline "Kennedy, Cassidy, colleagues introduce legislation to reauthorize and reform NFIP" is exact, and that single source substantiates all three promise prongs: Kennedy co-introduced (with Cassidy and Democrat Menendez, plus six others) a bipartisan bill to reauthorize/extend the NFIP, "place guardrails on FEMA's Risk Rating 2.0" to curb premium hikes (lower premiums), and that "emphasizes prevention and mitigation efforts" (flood mitigation). The 2024 source confirms he "introduced the National Flood Insurance Program (NFIP) Extension Act of 2024" as lead sponsor, with the quote verbatim. The December 2024 source confirms he "requested unanimous support to pass his bill" on the Senate floor (blocked), with the quote verbatim. This establishes REAL leadership — co-lead on the bipartisan reform bill and lead sponsor of extension acts he personally drove to the floor — satisfying the CHAMPIONED bar (leading/authoring, not merely voting). Confidence held at 0.8 rather than higher because the comprehensive three-prong reform (premium guardrails + mitigation) has not been enacted and maps to the bill where Kennedy is one of several co-sponsors (Cassidy listed first), and because the original rationale includes ancillary claims (specific bill numbers, Public Law 115-396, a Sept 2023 floor date) not documented by the three cited sources; those extras are not load-bearing, as the cited sources independently support the outcome. The promise verb is "advancing his introduced bipartisan legislation," which the sources demonstrably confirm.
