Updated 1:37 p.m. | Gov. Doug Ducey will appoint former Sen. Jon Kyl to the Senate following GOP Sen. John McCain’s death late last month, he announced Tuesday.

“I kept coming back to one name and on person: Jon Kyl,” Ducey said Tuesday. “There is no one in Arizona with the stature of Sen. Jon Kyl. He’s a man without comparable peer.”

Kyl only committed to serve through the end of the year, raising questions about the rest of McCain’s term, which ends in 2022.

Ducey, a Republican, was required by law to appoint a member of McCain’s party to fill his seat. Because of the timing of McCain’s death, the governor’s appointment would theoretically serve through most of 2020. A special election is expected to be held in 2020 to serve out the remainder of McCain’s term, which ends in 2022.

“People automatically assumed that this appointment will serve through 2020,” Ducey said at a Tuesday press conference. “I haven’t been able to get that assurance from Sen. Kyl yet. What I have gotten is a commitment to serve Arizona through at least this session of Congress and it’s my hope that he serves longer”
