Donald Trump told supporters Saturday that reports about delegates planning a last-ditch effort to try to deny him the GOP presidential nomination at next month's convention is a "hoax.""Believe me. By these people right here, it's all made up by the press. OK? It's all made up. It's, it's, it's a hoax, I'm telling you," Trump said at a rally in Las Vegas. Trump said he watched a report about the effort on CNN on Friday."Breaking news! There will be this and that at the convention," Trump yelled, mocking the network's report. "Who are they gonna pick? I beat everybody. But I don't mean beat. I beat the hell out of them, right? Beat the hell out of them."
