Perez anamrithi mwenyekiti wa muda Donna Brazile, ambaye alichukua wadhifa huo baada ya Mwakilishi Debbie Wasserman Schultz kuondolewa madarakani katikati ya mwaka wa 2016 wakati barua pepe zilizovuja zilionyesha kuwa baadhi ya wanachama wa DNC, ambao wameahidi kutoegemea upande wowote katika kura za mchujo za urais, walimpendelea Clinton badala ya Sanders.
