Arizona Governor Doug Ducey, R, will appoint former Sen. Jon Kyl, R-Ariz., to fill the Senate seat left by the late Sen. John McCain, R-Ariz., the Arizona Republic reports.

Gov. Ducey will announce Kyl's appointment at a press conference Tuesday morning at the Arizona Capitol after notifying Cindy McCain. She endorsed the appointment on Twitter.

Kyl, 76, retired from the Senate in 2013, previously serving as Senate minority whip. At the time, he indicated he would not seek elected office again. If he has not changed his mind, it's likely he will not run for another term once the rest of McCain's term expires.

Update: 

The New York Times reports that Kyl has only committed to serve until the new Congress begins in January. He has indicated he is open to serving until 2020, but will not run for re-election if he does so.
