Former Senator Jon Kyl Dies at 84
Jon Kyl, former Republican U.S. senator from Arizona, died Wednesday at 84. A neurological disorder manifesting as dementia was the cause, according to a family friend.
- Kyl served in the House from 1987 to 1995, then won three Senate terms.
- 2013 marked his exit as Senate minority whip, the No. 2 Republican.
- 2018: Gov. Doug Ducey appointed him to fill John McCain's vacant seat.
- December 2025: Kyl disclosed his dementia diagnosis and withdrew from public life.
Why it matters: Kyl's policy reach extended well beyond his tenure. He authored landmark tribal water-rights legislation and helped shape Arizona's groundwater code as a lawyer before entering politics.
- 2004 legislation gave the Gila River Indian Community rights to water equivalent to roughly 313,500 Olympic pools annually.
- After leaving the Senate, he guided Brett Kavanaugh's confirmation to the Supreme Court.
