All three cited sources are reachable and every quote appears verbatim. The CHAMPIONED leadership bar is met on both prongs of the promise. BORDER SECURITY: The Marathon Strategies 'Meet the Freshmen' profile confirms verbatim that 'In 2024, he introduced the Border Security State Reimbursement Act to reimburse states for costs associated with securing the United States border' — i.e., Curtis authored/introduced his own bill, which is leadership, not a mere vote. The Senate primary source confirms he voted Yea on S.5 (Laken Riley Act, Vote 7, Jan 20 2025, passed 64-35, enacted as Public Law 119-1), corroborating border-enforcement activity. IMMIGRATION OVERHAUL: The same Marathon source independently states Curtis 'co-sponsored the Dignity Act' comprehensive reform in the House, and Wikipedia confirms verbatim that he 'co-authored' HR 1044, the Fairness for High-Skilled Immigrants Act, and advocated for it on the House floor. Authoring a border bill plus co-sponsoring/co-authoring immigration-reform legislation constitutes real legislative leadership beyond votes, supporting CHAMPIONED. Confidence held at 0.8 (not higher) because the rating characterizes his DIGNITY Act role as 'original cosponsor/co-introducer' whereas the verified source says plainly 'co-sponsored,' and because the authored border bill and the DIGNITY overhaul were not enacted — the systemic overhaul is led/attempted, not achieved. But the promise was to 'work to' secure the border and overhaul immigration, and documented leadership on both prongs sustains the rating.
