Former Arizona Senator and GOP Leader Jon Kyl Dies at Age 84

Former Arizona Gov. Doug Ducey, who regarded Kyl as a mentor, recalled that Kyl was a “workhorse” who would sit in coach on flights, reading proposed bills and Senate business rather than seeking attention.
Kyl once told former Supreme Court Justice Sandra Day O’Connor that many of his most important accomplishments involved “preventing bad things from happening” rather than forcing good policies through Congress.
Kyl’s family described him as a man who loved and explored Arizona “with vigor, curiosity and wonder,” and said his public service was guided by faith, honor, warmth and love. The family said memorial details would be announced later.
Between his Senate terms, Kyl worked for Covington & Burling as a lawyer and lobbyist; reported clients included Anheuser-Busch, Georgetown University, Merck, Northrop Grumman, Qualcomm, Raytheon and Walmart. He was also named to Time’s 100 most influential people list in 2010.
In his final months before withdrawing from public life, Kyl remained active as a frequently cited expert on the Constitution, adding to his influence beyond his elected positions.
