Donald Trump calls Hillary Clinton 'Devil'

WASHINGTON: Republican presidential nominee Donald Trump’s rhetoric on the campaign trail grew even darker on Monday after a poll showed him trailing Democratic rival Hillary Clinton.

Criticizing Vermont Senator Bernie Sanders’ endorsement of Clinton, Trump pulled no punches. "He made a deal with the devil. She’s the devil," Trump said of Clinton at a ral ly in Mechanicsburg, Pennsylvania.

Trump, who has come under withering criticism for his attacks on the family of slain Army Captain Humayun Khan, also fired political adviser Ed Brookover on Monday.

A CNN poll released on Monday showed Clinton with a 52% to 43%lead over Trump.

Hours after the poll numbers were released, Trump told a crowd in Columbus, Ohio, that he worries the general election in November will be "rigged" against him, launching a fresh attack on the legitimacy of a US system his candidacy is premised on upending. "I’m afraid the election’s gonna be rigged, I have to be honest," Trump said.
