PHOENIX — Jon Kyl, a prominent figure in Arizona politics and a key player in the U.S. Senate for nearly three decades, passed away on September 16, 2026, at the age of 84. His family announced that Kyl succumbed to complications from a neurological disease, a condition he had publicly disclosed in December 2025, which prompted him to step back from public life.
Kyl’s extensive career began well before his election to Congress. He initially worked as an attorney for the Salt River Project, where he contributed significantly to the development of the state’s water policy. His legal expertise was instrumental in the drafting of the Arizona Groundwater Management Act, a pioneering piece of legislation aimed at regulating groundwater usage in a region frequently afflicted by drought. Over 26 years in Congress, he is credited with seeing 18 of his bills become law, addressing a wide array of issues ranging from crime victims’ rights to land exchanges and federal court appointment ethics.
In the Senate, Kyl championed water rights issues, notably as the author of the Arizona Water Settlements Act, passed in 2004. This landmark legislation established one of the largest tribal water rights settlements in U.S. history, ensuring the Gila River Indian Community access to a substantial annual water supply. His efforts significantly reformed previous agreements governing water rights in Southern Arizona, underscoring his commitment to addressing the complex needs of water management in the state.
Arizona Governor Katie Hobbs paid tribute to Kyl, noting his deep commitment to public service. “Throughout his decades of public service in the House and Senate, he was a dedicated statesman who always cared deeply for our state,” Hobbs wrote in a social media post, reflecting on Kyl’s long-standing influence on Arizona’s governance.
Kyl was born on April 25, 1942, in Oakland, Nebraska, and grew up in a political household; his father served as a U.S. Representative for over a decade. After moving to Arizona for college, Kyl earned a law degree and established a career that combined legal practice with civic leadership, eventually leading him to a seat in the U.S. House of Representatives in 1987. He later won a Senate seat in 1994 following the retirement of Sen. Dennis DeConcini.
During his tenure, Kyl rose through the ranks, becoming the Republican whip in 2007, a position he held until his retirement in 2013. Colleagues admired his work ethic and dedication, with Senate Minority Leader Mitch McConnell praising his quiet yet persistent push for essential legislation, including those concerning critical water rights.
The impact of Kyl’s work extends beyond legislation; it influences future generations navigating the complexities of water management in the arid West. Sarah Porter, who directs the Kyl Center for Water Policy at Arizona State University, noted his practical approach and willingness to engage with contemporary water challenges, a legacy that will continue to shape policy discussions in Arizona.
Kyl leaves behind a significant legacy, marked by his dedication to public service, legal acumen, and commitment to Arizona’s water rights. His passing has resonated deeply within the community and the political landscape he helped shape.
