Donald Trump was very classy and thanked Indiana and Bobby Knight. He called Ted Cruz a “tough competitor” and called for republicans to unite against Hillary Clinton. Even RNC Chair Reince Preibus has acknowledged Trump is the “Presumptive Nominee” now. .@realDonaldTrump will be presumptive @GOP nominee, we all need to unite and focus on defeating @HillaryClinton #NeverClinton — Reince Priebus (@Reince) May 4, 2016
