some tough questions after a ninth day of wikileaks e-mails. more on that in a moment. but we begin with mary bruce, covering the trump campaign. >> reporter: tonight, donald trump is lashing out. saying the election can't be trusted. >> the election is being rigged by corrupt media pushing false allegations and outright lies in an effort to elect hillary clinton president. >> reporter: without evidence, trump is increasingly saying he's the victim of a conspiracy. in less than 48 hours, trump claiming a rigged election more than 20 times, even suggesting "saturday night live" is in on it. >> what about all the women accusing you of sexual assault? >> they need to shut the hell up. >> reporter: tweeting, time to retire, boring and unfunny show. alec baldwin portrayal stinks. media rigging election.

but the clinton campaign says trump is using scorched earth scare tactics. >> he knows he's losing. >> reporter: trump is ramping up his attacks as more women accuse him of sexual misconduct. the latest to speak out, kathy heller saying that in the mid-'90s, trump kissed her without consent at a mother's day event. allegation, saying it would have been the talk of palm beach for the past two decades. >> false stories, all made up. lies. lies. >> reporter: tonight, trump speaking about the suspected firebombing of an office,

and with the final debate just three days away, trump has a new unfounded theory. clinton may be on drugs. >> i think we should take a drug test prior to the debate. i do. because i don't know what's going on with her. but at the beginning of her last debate, she was all pumped up at the beginning. and at the end, it was like, take me down. >> reporter: and tom, despite the controversy, our new poll shows trump supporters are sticking with him, but their enthusiasm is waning, down 12 points since last month. >> tom? >> mary, thank you. >>me holed up with her debate prep team in new york today. the third and final showdown wednesday night. but the campaign also facing mounting questions over e-mails revealed aftileaks. here's devin dwyer. >> reporter: tonight, hillary clinton is in seclusion to prepare for this week's final debate. no public events scheduled for five days. this, as wikileaks released hundreds of e-mails believed

account. by what the fbi suspects could be russian hackers. the daily drip becoming a rolling october surprise. one podesta e-mail claims to include transcripts of private speeches clinton gave to goldman sachs. while they haven't been independently verified by abc news, critics say clinton's public is a lot less tough in private when paid a $225,000 speaking fee. clinton appears to have told goldman bankers in 2013, there's nothing magic about regulations. too much is bad, too little is bad. the people that know the industry belt better than anybody are the people that work in the industry. while there's no bombshell, in one message last year, close clinton aides express frustration with clinton's inability to do a national interview and communicate genuine feelings of remorse or regret about her e-mail server.

worst terrorist organizations we have ever seen, in history i think, probably. and i think it's very important for everybody that can do something to stand up and fight back. >> reporter: the iraqi military has dropped leaflets on mosul telling residents to stay away from isis positions. around 1 million people are expected to flee the fighting in what the u.n. says could be the biggest humanitarian crisis this year. tom? >> alex, thank you. meantime, more hostile activity involving a u.s. warship off the coast of yemen. the navy destroyer uss mason firing to protect itself from what may have been missiles from yemen. the navy is reviewing the incident, coming days after the u.s. military launched retaliatory strikes which knocked out three radar sites in yemen. back here at home, to some dangerous weather out west. a powerful storm lashing the coast from northern california to the canadian border. knocking down trees and knocking
