This resolution formally honors the life and career of Jon Llewellyn Kyl, a former U.S. Senator from Arizona who died at age 84. It recounts his biography and public service, including his education at the University of Arizona, his legal career in Phoenix, four terms in the U.S. House of Representatives, and nearly two decades in the Senate spanning 1995 to 2013, plus a brief return to the Senate in 2018 following John McCain's death. The resolution highlights his leadership roles within the Senate Republican Conference and his policy work on water issues, crime victims' rights, and national security, noting institutions named in his honor at Arizona State University and the University of Arizona. As a formal expression of the Senate's sentiment, the measure does not create new law, spend money, or set any timeline; it simply records the Senate's sorrow at his passing, directs that the resolution be sent to the House and to Kyl's family, and provides that the Senate adjourn that day as a mark of respect. It affects no groups beyond serving as a tribute to Kyl, his family, and his legacy of public service.
