PHOENIX —

Martha McSally has reportedly been appointed to the Senate seat once filled by late Senator John McCain.

Arizona Governor Doug Ducey announced her appointment to the position Tuesday morning, replacing Jon Kyl who was sitting in McCain's seat.

He said in a tweet: "All her life, (McSally) has put service first — leading in the toughest of fights. With her experience and record of service, Martha is uniquely qualified to fight for #Arizona in the U.S. Senate."

Governor Ducey recently announced that U.S. Sen. Jon Kyl will resign at the end of the year from the U.S. Senate seat he was appointed to less than four months ago following the death of Sen. Jon McCain.

McSally lost her bid for Arizona's other Senate seat to Kyrsten Sinema just weeks ago.

"Martha McSally would be a very good member of the United States Senate, however she got there," Kyl said after the election. "And I regret that she didn't make it in her election."

"I can't think of anybody more qualified than Martha McSally," he added.

Cindy McCain weighed in on the appointment on Twitter, saying "Arizonans will be pulling for her, hoping that she will follow his example of selfless leadership."
