At a campaign event on Saturday in Pittsburgh, Pennsylvania, Democratic presidential nominee Hillary Clinton criticized Trump's stance about the Nov. 8 election being rigged.
"Donald Trump did something the other night that no other presidential nominee has ever done of either party, he refused to say he would respect the results of this election. Now make no mistake about this my friends he is threatening our democracy. We know in our country the difference between leadership and dictatorship," she said.
Trump suggested he might not accept the election result if his Democratic opponent Hillary Clinton wins on Nov. 8, called her a "nasty woman," and repeated hard-line conservative positions on issues such as abortion and immigration.
