Arizona Gov. Doug Ducey appointed former Sen. Jon Kyl on Sept. 4 to succeed the late Sen. John McCain in the U.S. Senate.

Kyl agreed to serve the rest of the year but didn’t commit to continuing through 2020. If Kyl steps down at the end of the year, Ducey will be required to appoint another replacement.
