PHOENIX - Republican Rep. Martha McSally has filed signatures to be on the ballot to run for U.S. Senate.
Her campaign said she filed more than 13,800 signatures on Tuesday in order to run in the Republican primary. She'll be running against Kelli Ward and Joe Arpaio.
McSally currently represents Arizona's second district in Congress, which covers most of Tucson.
McSally's filing makes her the sixth candidate in the race across three parties. Democratic front-runner Rep. Kyrsten Sinema filed her signatures earlier on Tuesday. Also running are Democrat Deedra Abboud and Green party candidate Eve Reyes-Aguirre.
