Earlier this week, Republican presidential nominee Donald Trump refused to say whether he would accept the outcome of the Nov. 8 election, casting doubts on the "rigged" process during the third and final presidential debate in Las Vegas.

"I would like to promise and pledge to all of my voters and supporters, and to all of the people of the United States, that I will totally accept the results of this great and historic presidential election -- if I win," he said at a rally in Delaware, Ohio.
Trump then pointed to the 2000 election as historical precedent not to concede, saying if then Democratic nominee Al Gore and George W. Bush had been posed the same question weeks before that year's presidential election, there would never have been a recount.
