Former GOP Sen Jon Kyl announces dementia diagnosis, steps away from public life

Former Republican Sen. Jon Kyl announced on Tuesday he is withdrawing from public life after being diagnosed with dementia.

"I was blessed to represent the people of Arizona in Congress and to have numerous other opportunities to contribute to the political and civic life of our nation and state," Kyl said in a statement. "However, the time has come for me to withdraw from public life. I have been diagnosed with a neurological disease manifesting as dementia."

Kyl represented Arizona's 4th Congressional District in the House from 1987 to 1995 before serving in the U.S. Senate from 1995 to 2013.

After leaving the Senate, Kyl joined the lobbying firm Covington and Burling, before being appointed in 2018 by then-Gov. Doug Ducey to fill the vacancy caused by the death of former Sen. John McCain.

Kyl moved to Arizona as an 18-year-old freshman to attend the University of Arizona, where he met his wife.

The university said Kyl devoted more than two decades to public service, leaving a lasting impact on water policy, national defense and intelligence.

"His leadership, integrity, and commitment to service reflect the highest ideals of public life," the university said in a statement.
