Mississippi Edition

Hillary Clinton is officially the Democratic nominee for president. We'll talk live with a Mississippi delegate in Philadelphia, Pennsylvania. Then, state Republican leaders defend their party's work at the Neshoba County Fair. Later, starting a dialogue in Jackson between law enforcement and communities of color. And, a rally is scheduled in Tupelo tomorrow in response to the killing of an unarmed black man -- Antwun "Ronnie" Shumpert -- by a police officer in June.
