Rachel Maddow to help moderate first Democratic primary debate

The first debate of the Democratic presidential primary will be moderated by Savannah Guthrie, Lester Holt, Chuck Todd, José Díaz-Balart of Telemundo, and the MSNBC commentator Rachel Maddow, NBC News announced on Tuesday.

The two-night event, set for June 26 and 27 in Miami, is the first nationally televised clash of the sprawling Democratic field and will air in prime-time on MSNBC, Telemundo, and — in a rarity for a primary debate — on NBC broadcast stations around the country.
