Jon Kyl, Arizona senator with Iowa roots, dies at 84
Former U.S. Sen. Jon Kyl of Arizona, a Republican leader who guided Supreme Court Justice Brett Kavanaugh's confirmation and shaped landmark Western water policy, has died at 84. His family announced that Kyl died from complications of a neurological disease, having stepped back from public life in December 2025 after a dementia diagnosis.
Kyl's story includes deep Iowa ties. He was born in Oakland, Nebraska, in 1942 but grew up in a rural farming district in Iowa that his father represented in the U.S. House. At 18, he left for the University of Arizona, where he met his wife, Caryll, and later earned a law degree.
What did Jon Kyl accomplish in Congress?
Kyl spent nearly three decades in Washington, serving eight years in the House and 18 in the Senate, plus a brief partial term filling the vacancy left by the late Sen. John McCain. He rose to minority whip during his final full term and was known for his intense work ethic.
In a 2012 floor speech, then-Minority Leader Mitch McConnell called Kyl's work ethic legendary, noting he labored behind the scenes for 15 years on tribal water rights. Kyl authored the 2004 legislation that delivered one of the largest tribal water settlements in U.S. history, giving the Gila River Indian Community enough water to fill nearly 313,500 Olympic-sized swimming pools each year.
Kyl also shaped Arizona's 1980 groundwater code, a first-of-its-kind regulatory framework for managing water in the drought-prone state. Arizona State University's Kyl Center for Water Policy bears his name.
How did Kyl influence the Supreme Court and national policy?
Kyl returned to the Senate in 2018 after being appointed by then-Gov. Doug Ducey to replace McCain. He served as Kavanaugh's chief Sherpa, guiding the nominee through a contentious confirmation process. President Donald Trump praised the appointment, saying he looked forward to working with the extraordinary senator.
Earlier in his career, Kyl backed legislation to authorize a border fence along the U.S.-Mexico border. He also joined Democrats on a failed immigration bill that would have provided a path to citizenship and guest-worker status.
Ducey, who considered Kyl a mentor, called him a true statesman and a workhorse among Washington's show horses. He credited Kyl with keeping the Republican caucus united against Obamacare and for his strong support of Israel.
What did colleagues say about Jon Kyl?
Sarah Porter, director of the Kyl Center for Water Policy, said Kyl cared deeply about the public good and thought about future generations. She described him as quite a dynamo until recent years.
Kyl himself reflected on his legacy in 2012, telling former Supreme Court Justice Sandra Day O'Connor: At the federal level, probably a lot of my better achievements were in preventing bad things from happening than forcing good things to happen.
In his final public statement disclosing his dementia diagnosis, Kyl recalled Ronald Reagan's words when the former president revealed his own Alzheimer's diagnosis. Kyl said he shared Reagan's confidence in America's future and considered himself a very fortunate man.
What is Jon Kyl's lasting impact on Iowa and the nation?
While Kyl spent his political career representing Arizona, his Iowa upbringing shaped his values of hard work and public service. His legacy includes water policy that sustains millions of Western residents, a Supreme Court justice he helped confirm, and a reputation for quiet, effective conservatism that many Iowa Republicans admire.
Kyl is survived by his wife, Caryll, and their family.
