Presumptive Republican presidential nominee Donald Trump addresses supporters during a rally at the Anaheim Convention Center in Anaheim, Calif., on May 25, 2016. Trump peppered his speech with attacks on Clinton, using his much-repeated term, "Crooked Hillary." "She doesn't have the temperament to be president," he said. "She's got bad judgment. She's got horribly bad judgment, and that was stated by none other than crazy Bernie (Sanders). Bernie said that Hillary Clinton has bad judgment."
