Julián Castro's presidential campaign announced Thursday that the former Housing and Urban Development secretary will participate in a Fox News town hall on June 13 in Arizona.

"Secretary Castro is looking forward to the opportunity to share his vision for the future of our country with the FOX News audience in a state that should be critical for Democrats in 2020," Castro's campaign manager Maya Rupert said in a statement.

The event will be held in Phoenix and hosted by Bret Baier of "Special Report" and Martha MacCallum of "The Story."

The town hall will be an opportunity for Castro to reach a new set of voters amid languishing poll numbers. The former San Antonio, Texas, mayor has polled close to 2 percent in most national and state surveys.

Castro will be the fifth 2020 candidate to appear in a Fox News town hall, following Sens.
