Columbus, Ohio (CNN)Donald Trump on Monday took his complaints about the "rigged" political system one step further.
"I'm afraid the election's going to be rigged. I have to be honest," Trump told voters in Ohio, a crucial swing state.
Trump's comments Monday came as he decried Vermont Sen. Bernie Sanders for endorsing Hillary Clinton in the Democratic primary, even as some Sanders supporters have continued to resist unifying behind the nominee. Trump has sought to siphon off Sanders supporters and draw them to his campaign.
