Don't miss a special Fox News Channel town hall event, Sunday night at 8:00pm ET

Harris Faulkner hosts the live-audience event in Phoenix, featuring Arizona Senate candidates U.S. Rep. Martha McSally (R) and U.S. Rep. Kyrsten Sinema (D).

The conversation will focus on hot-button issues in the nationwide immigration debate.

Throughout the town hall, Faulkner will feature thoughtful discussions with Arizonans who will decide in November who will replace Republican Jeff Flake in the U.S. Senate. 

Those set to appear at the event include an Arizona rancher who lives on the U.S.-Mexico border, the head of a local Border Patrol officer’s union and a high-profile immigration activist. Each of the candidates will sit down for a pre-taped interview with Faulkner to air at the town hall. 

The latest Fox News poll of the race shows Sinema leading by three points, within the margin of error. Sinema has served in the House of Representatives in 2013, representing Maricopa County, while McSally has served in Congress since 2015, representing the Tucson area.

Tune in Sunday night at 8:00pm ET for Town Hall America with Harris Faulkner.
