2020 United States Senate special election in Arizona
2020 United States Senate special election in Arizona will be held on November 3, 2020. Following the death of Republican U.S. Senator
John McCain on August 25, 2018, Governor
Doug Ducey was required by Arizona law to appoint a Republican
to fill the vacancy in McCain's Senate seat. 
In September 2018, Ducey appointed former U.S. Senator
 Jon Kyl to fill McCain's seat until after the Special Election of November 2020. This will determine who serves the remainder of the term until January 2023. Kyl did not complete the term, and resigned on December 31, 2018.
On December 18, 2018, Ducey announced in a statement that
 Martha McSally would be appointed to fill the seat following Kyl's resignation.
McSally was sworn in as Arizona's junior senator on January 3, 2019.
