Sue Donahue has been chosen to fill out the Arizona Senate term of Kelli Ward, who is running for the U.S. Senate.
Ward resigned her seat last week to focus on her Republican primary challenge to U.S. Sen. John McCain, a five-term senator and 2008 Republican presidential nominee.
Ward is a physician from Lake Havasu City. The district she represented spans much of Mohave and all of La Paz counties.
Donahue was selected Tuesday to replace Ward on a unanimous vote by the Mohave County Board of supervisors.
Donahue is a Republican from Lake Havasu City who has been an administrative assistant to Mohave County Supervisor Buster Johnson.
She told supervisors that she won't run for a full term when the state Senate seat opens up in the 2016 election.
