>> reporter: sin city showdown ended as it began without a omcustary handshake between the presidential nominees but one of the most controversial moments of the night came when donald trump refused to said if he would accept the outcome of the general election. >> i'll tell you at the time. i'll keep you in suspense. >> that is horrifying. every time donald thinks things are not going in his direction he claims whatever it is is rigged against him. >> reporr: arizona's jeff flake immediately condeemed the remarks on social media as it clinton's campaign. this group of uncommitted voters was left undivided. >> a lot of the population from the political process to say no matter what the results are, i will be okay with it, without knowing what is going to happen, i don't think anybody would do that about anything that was serious. >> reporter: the third and final

cbs news contributor bob schieffer says trump's comments mark an unprecedented departure in the history of this country. >> this is very, very unusual. i mean, it raises the question what will he do if he doesn't accept the results? i assume he is talking about filing a lawsuit or something. surely he's not thinking about trying to stage a coo. what is he talking about here? this is not the united states of america and there is no other way that you can say it. it's dangerous to be talking that way because it threatens and raises questions about the very foundations of what this nation is about. we have peaceful transfers of power in this country and to somehow to suggest that we are not going to do it that way. >> trump's running mate, indiana

threat not to accept the election results stems from the bias of the media and what he says is the very real existence of voter fraud in this country, but pence insists trump will accept the election outcome. >> he's a candidate for the president of the united states of america. he has every right. he has the prerogative to wait and see how the election comes out. sometimes extraordinary circumstances develop, major. we saw that in the year 2000 when al gore conceded the election and his concession and the matter ultimately was involved in the supreme court of the united states. >> you may recall the 2011 election was one of the closest in history. george w. bush failed to win the the outcome hinged on florida where the margin was so close that it triggered a mandatory recount. al gore dropped his challenge after the supreme court voted to end the recount. so following the debate, democratic vice presidential nominee tim kaine tweeted this

where the special forces, he told us, we can do it. but the truth is that mosul offensive has slowed to a crawl in the last 48 hours. these kurdish fighters built new defensive positions 15 miles east of the city. they recaptured this area on monday and now look like they are planning on staying put. in the village of kaballi, you can see one of the reasons it's such slow going. when isis fled the village houses here reeked with homemade bombs. they have detonated some and dismantled others. but mohammed saeed has come home to find his house still laced with explosives. he fled two years ago, along with all of the other residents. why would isis put explosives in your house?
