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.

Kyl, 83, became one of Arizona's most prominent Republicans during a career that spanned nearly three decades across both chambers of Congress, including a stint as Senate minority whip.

"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.
