What they stand for
Hirono has spent years focused on a few core fights. Each is tied to bills actually introduced or votes actually cast.
- 01Supports federal recognition of Native Hawaiian veteran benefitsHirono sponsored the Parity for Native Hawaiian Veterans Act of 2025 (S.1853) and the Filipino Veterans Family Reunification Act of 2025 (S.461), both of which address federal benefits and family reunification pathways for veterans from Hawaii and the Pacific region. These bills reflect a consistent pattern of legislative attention to veteran communities with ties to Hawaii and the broader Pacific.
- 02Seeks to protect and preserve Social Security benefitsHirono sponsored the Protecting and Preserving Social Security Act (S.2614), a reintroduced measure directed at the federal Social Security program. She has also sponsored the Public Service Freedom to Negotiate Act of 2025 (S.1352), which concerns collective bargaining rights for public employees, reflecting a pattern of legislative engagement with federal benefit and labor protections.
- 03Advances health data privacy and reproductive data protectionsHirono sponsored the My Body, My Data Act of 2025 (S.2029), which addresses the privacy of personal health and reproductive data. The bill has been reintroduced across multiple Congresses, indicating sustained legislative focus on limiting the collection and use of sensitive health information held by private entities.
- 04Promotes AANHPI history education and recognition in schoolsHirono sponsored the Teaching Asian American, Native Hawaiian, and Pacific Islander History Act of 2025 (S.1844) and the Fred Korematsu Congressional Gold Medal Act of 2025 (S.338). These bills address the inclusion of AANHPI history in educational curricula and the formal congressional recognition of civil rights figures, respectively.
- 05Sponsors measures for Hawaii's environmental and agricultural needsHirono sponsored the Continued Rapid Ohia Death Response Act of 2025 (S.85), addressing a fungal disease threatening Hawaii's native ohia tree population, the AG RESEARCH Act (S.1825) focused on agricultural research, and the Sustainable Vessel Fuel Act (S.692) concerning maritime fuel standards. These bills reflect legislative engagement with Hawaii's land, ecology, and maritime economy.
