PHOENIX — Phoenix will host a Democratic Party presidential debate on March 15, two days before Arizona presidential preference election, the Democratic National Committee and the Congressional Hispanic Caucus announced Friday.

The debate will air live on CNN and Univision. 

The debate location has not been announced, but people familiar with the plans said the event could be at downtown's Phoenix Convention Center or the Arizona Federal Theatre, formerly the Comerica Theatre, across the street from the Sandra Day O'Connor Federal Courthouse. 

People who wish to attend must RSVP at the party website.

The debate site and date confirms Arizona's status as a key battleground state in the race for the White House and control of the U.S. Senate.

"I personally want to thank Phoenix Mayor Kate Gallego, Senator Kyrsten Sinema, members of Congress Ruben Gallego and Greg Stanton, and the Congressional Hispanic Caucus for their assistance throughout the selection process," said DNC Chair Tom Perez. "Arizonans can't ask for better local and national advocates."

Perez is scheduled to visit Phoenix on Monday, two days ahead of President Donald Trump's rally at Veterans Memorial Coliseum. 

Arizona's Democratic primary is open only to registered Democrats. The deadline to register or change your party preference is Tuesday.
