Former U.S. Senator Jon Kyl, a prominent figure in Arizona’s political landscape, has passed away at the age of 84 after a battle with a neurological disorder. His death, which occurred on Wednesday, September 16, was confirmed by Gordon James, a close friend of Kyl’s family. The news comes approximately nine months after Kyl announced he would be retreating from public life due to a diagnosis of dementia, a condition impacting cognitive abilities.

In his statement issued in December 2025, Kyl reflected on the challenging path ahead, remarking, “My family and I now head down a path filled with moments of joy and increasing difficulties.” Despite the difficulties associated with his condition, he expressed his gratitude for the support he received from his loved ones, maintaining a perspective of gratitude through his struggles: “I remain a very fortunate man.”
Born on April 25, 1942, in Oakland, Nebraska, Kyl grew up in Iowa, where he was influenced by his father’s career in public service. His father represented a rural district in Congress, which likely inspired Kyl’s own journey into politics. Kyl moved to Arizona, where he earned a law degree from the University of Arizona—a place where he also met his future wife, Caryll. Together, they raised two children during their life in the state.
Kyl’s political career began in earnest when he was elected to the U.S. House of Representatives in 1987, serving until 1995. He was subsequently elected to the Senate, where he remained until 2013, assuming a leadership role as Senate Minority Whip during the final years of his time there. Notably, Kyl was known for his collaborative spirit and commitment to finding bipartisan solutions.
Following his departure from the Senate, Kyl shifted gears to work as a lobbyist. However, he was called back to public service in 2018, when he was appointed to fill the Senate seat left vacant by the late John McCain’s death. At the time, President Donald Trump remarked that he was “enthusiastic” about working with Kyl, describing him as an “extraordinary senator.”
In the wake of Kyl’s passing, tributes poured in from various leaders across Arizona. Governor Katie Hobbs expressed the community’s grief, stating, “Arizonans are mourning the loss of former U.S. Senator Jon Kyl. Throughout his decades of public service in the House and Senate, he was a dedicated statesman who cared deeply for our state.” Her message on social media conveyed condolences to Kyl’s family and recognition of his commitment to public life.
Adrian Fontes, Arizona’s Secretary of State, also paid tribute, highlighting Kyl’s contributions on critical issues, such as tribal water rights. Fontes noted, “He made a lasting contribution through his work, helping to bring stakeholders together to advance important water settlements in Arizona. His dedication to resolving some of the West’s most complex water challenges is his legacy.”
The loss of Kyl resonates deeply within the communities he served, reflecting on nearly three decades of service dedicated to improving the lives of Arizonans. Lawmakers and citizens alike recognised his efforts and the impact he had in shaping the state’s policies and addressing its challenges.
As the state mourns the passing of a significant political figure, Kyl’s commitment to service and legacy of public work will be remembered by those who had the privilege to know him and those who were influenced by his policies.
