Republican Donald Trump is stepping up attacks against Democrat Hillary Clinton.
FOX's Rachel Sutherland reports:
Trump has a new nickname for Clinton, unveiled in Pennsylvania as he criticized Bernie Sanders' decision to endorse her:
(Trump) "If he would have just not done anything, just go home, go to sleep, relax, he would have been a hero. But he made a deal with the devil. She's the devil."
Trump also said at a rally in Ohio that he's worried about the November election because he fears the system is rigged. Trump is back on Twitter, calling Clinton a pathological liar.
