WATCH: McSally, Sinema U.S. Senate debate

Arizona PBS, in partnership with The Arizona Republic and azcentral.com, hosts the only live television debate between U.S. Senate candidates Martha McSally and Kyrsten Sinema.

The hourlong debate covers local and national issues. McSally, a two-term congresswoman from Tucson, and Sinema, a three-term congresswoman from Phoenix, are competing for an open seat in the U.S. Senate. Incumbent Jeff Flake has declined to seek a second term.

“Arizona Horizon” host Ted Simons and Arizona Republic/azcentral.com reporter Maria Polletta serve as moderators for the debate.
