Verified all four cited sources. The three PRIMARY sources carry the CHAMPIONED outcome and were confirmed verbatim: (1) rounds.senate.gov confirms Hyde-Smith is "chair of the Senate Pro-Life Caucus" and that she and Rounds "today introduced the Dismemberment Abortion Ban Act of 2026" (dated June 24, 2026) — genuine authorship/leadership of original federal legislation, not a mere vote; (2) hydesmith.senate.gov contains her verbatim pledge "As chairman of the Pro-Life Caucus, I will lead the fight in the Senate to protect unborn children and their mothers from abortion" (Jan 5, 2023); (3) hydesmith.senate.gov/pro-life confirms she "is also serving as the chair of the Senate Pro-Life Caucus in the 119th Congress" and references the Dismemberment Abortion Ban Act of 2026 establishing "a federal prohibition on dilation and evacuation." Together these show sustained LEADERSHIP — chairing the caucus and authoring/introducing federal legislation — which satisfies the CHAMPIONED bar (led/authored, not merely voted or supported). The fourth source (NBC News) returned HTTP 403 to direct fetch, but this is an anti-scraping block, not a dead/fabricated link: WebSearch returned the exact article by title and corroborating CNN and UPI coverage confirm Hyde-Smith blocked Sen. Duckworth's IVF bill on Feb 28, 2024, objecting that it "goes way too far," with the Life at Conception Act context corroborated. That source is supplementary; the CHAMPIONED determination stands on the three verified primaries even without it. CHAMPIONED (not FULL) is correct because the promised end-state — every unborn child protected under U.S. federal law — remains unachieved post-Dobbs, while she is unmistakably leading the ongoing federal effort the vow described.
