Nightly news begins right now. This is nbc nightly news with lester holt. Good evening. We expect to hear diametrically opposed views at the height of a president ial campaign but usually not from the same sides. Tonight thats whats happening as donald trump ramps up his fiery and unsupported predictions of largescale election fraud, even as other key republicans, mate, say it just isnt so. Nonetheless, a rigged election has become the central theme of trump rallies as we head into the final three weeks of the campaign. Whether its meant to fire up the base or provide an excuse in case of defeat, it is raising tensions and fresh worries about the dark consequences of such talk. Nbcs Peter Alexander has details. Reporter in Donald Trumps arsenal of accusations, its become one of his most potent claims. Election. Its a rigged election. This is a rigged system, folks. Reporter now facing a growing deficit in the polls and amid reports his family explored a Trump Tv Network for after the election, today trumps pouring fuel on his incendiary allegation. On twitter, claiming largescale voter fraud, questioning the fundamental fairness of the election. A message resonating with his supporters. Do you think theres largescale voter fraud in this country . Yes. Absolutely, positively. Reporter tonight Chris Christie telling nbc news im convinced that the election will be a fair one, and that the process will be one that will be accepted by the american people.

Demand that our Public Officials are upholding the integrity of the vote, but do all you can to respectfully participate in the process. To whine.

You shouldnt sew seeds of doubt unless you have some facts to back it up. Reporter here are the facts. Loyola traced voter fraud and found it practically nonexistent. Just 31 incidents out of one billion votes. Mr. Trump is using goes beyond just whats happening in the polling place. I think what hes trying to do is to send a message to his potential voters. Reporter the question tonight, will trumps message motivate enough voters in the key states that he needs to win . And tonight for the First Time SinceDonald Trumps controversial comments about women in that 2005 hot mike moment with access hollywood, were hearing from his wife Melania Trump, here with cnn. I said to my husband that, you know, the language is inappropriate, its because that is not the man that i know. And as you can see from the tape, the cameras were not on, it was only a mike. And i wonder if they even knew that the mike was on. Because they were kind of a boy talk and he was lead on, like egg on from the host to say dirty and bad stuff. Reporter that clip Melania Trump is referring to was recorded on an access hollywood press tour bus in the presence of others. Access hollywood, of course, is owned by nbc universal. Lester . Peter alexander, thank you. Tonight, police and federal agents are investigating the firebombing of a Republican Party office in North Carolina over the weekend. As the tone of the divisive and corrosive with 22 days until the election. We get more on that from our justice correspondent pete williams. Reporter tensions have been rising all year in a campaign thats seen undertones of violence. The fbi and atf are helping Police Investigate saturday nights firebombing of a county Republican Party office in hillsborough, North Carolina. No one was hurt, spray painted on a nearby wall, nazi republicans, leave town or else. And a swastika. The president of the newspaper says after it endorsed Hillary Clinton last month, the staffs been getting death threats, even the students who sell subscriptions. People are spitting on them, calling them vile names. Today somebody called and said that if we sent somebody to knock on his door, he would pour boiling water on him and sick his dogs on him. Reporter the sheriff of Milwaukee County wisconsin, david clark, a trump supporter, lit up about Big Government and media, its pick forks and torches time. Today he says hes advocating political change, not violence. But some talk this year has been ambiguous. The wall street journal interviewed a trump supporter last week in ohio who said if Hillary Clinton is elected, she should be, quote, taken out. It sounds like youre saying that it would be acceptable to assassinate a president . If shes corrupt, why should she be able to stay in office . Answer that question. Reporter the secret service wont talk about specific cases, but says it investigates all credible threats. Al baldasaro, a New Hampshire trump supporter, said agents called him after he said Hillary Clinton should be tried for treason, convicted and executed. On sunday, an online appeal asked for donations to help republicans reopen that firebombed office. The money was raised by a massachusetts democrat. Pete williams, nbc news, washington. Hillary clinton is facing new trouble of her own tonight on two different fronts. Both of them involving emails. One is the continued leaking of emails illegally hacked from chairman. A new batch published by wikileaks late today. The other separate situation involves continued fallout from her use of a private email server. New disclosures from the fbi today sparking yet another fire storm her campaign is working to put out. We get all the latest on all of it from nbcs andrea mitchell. Reporter Hillary Clinton heading out to practice for wednesdays final debate. And now facing yet another unexpected fire storm over her private emails. Today from the fbi email investigation, quoting an fbi agent accusing a Top State Department official of proposing a quid pro quo to resolve a dispute over whether a clinton email should be classified. The notes say, in exchange for marking the email unclassified, state would reciprocate by allowing the fbi to place more agents in countries where they are forbidden. Specifically, iraq. In rare agreement, donald trump and Speaker Paul Ryan jumped all over the highest level. And we cant let it happen as american citizens. Reporter the problem with that story line, the fbi and the Statement State Department say it never happened. Theres no quid pro quo. Absolutely not. Reporter in fact, both sides say it was an fbi official who brought up the question of placing agents overseas. Separately from the negotiation over classification. No linkage, no quid pro quo. Second, and the really emails, those stolen from her Campaign Chairman john podesta, and released by wikileaks, the u. S. Says, with help from russia. The wikileaks trove, not authenticated by the campaign or nbc news, include alleged transcripts from her speeches to goldman sachs. Revealing she changed her positions on trade, immigration, and wall street when she became a candidate, exactly what Bernie Sanders suspected. You gotta release the transcripts. Let everybody see them reporter now crack down on the big banks. Reporter but as a highly paid speaker, clinton appears to have told the bankers, the people that know the industry better than anybody are the people who work in the industry. But for all this, clinton is now 11 points ahead in our new poll tonight, and now expanding her campaign to red states, like utah, texas, georgia, even arizona, where Michelle Obama will campaign this week. The democrats hoping to win decisively and put to rest Donald Trumps talk of a stolen election. Lester . Overseas now to a major assault under way in the fight against isis. American forces assisting iraqis in a longawaited offensive to take back the city of mosul. The center of the islamic states power in iraq. Our chief Foreign CorrespondentRichard Engel is in iraq, taking us inside the command center for this major operation. Reporter the battle to drive isis from its iraqi stronghold mosul got off to a raucous Armored Vehicles race to the front lines. In most places isis pulled back. But not always, sending at least seven car bombs to attack iraqi and kurdish forces. This is the defining battle of president obamas war on isis, and its being coordinated here in this joint operations room. Iraqi officers on one side, their american advisers on the other. The americans control the skies, havou country, and have been launching artillery and air strikes to back up the iraqi advance. While the americans werent authorized to talk to us, the iraqi ground commander says so far coordination is working well. The american and the iraqi, one team. Reporter this base, qayyarah west, is now home to hundreds of american troops. Theyre working hard to fix the runway dug up by isis back hoes as soon as the holes land here, to support iraqi troops in mosul. Taking mosul is such a high priority because mosul is isiss last stand in iraq, the biggest city it holds. A symbol of isis power, attractive to wouldbe terrorists. We will liberate mosul, god willing, a soldier told us. But there are signs this wont be easy. Isis is very literally pursuing a policy of scorched earth. Today they dont plan to actually enter mosul itself, but to take a village nearby. Here isis set an oil well on fire. It was a deliberate act of sabotage. And many commanders fear that isis may have even worse in store for mosul itself. Isis torched the oil fields it used to fund its terrorism. Rather than see them go back to the Iraqi Government. Isis could fight to keep its capital in the Iraqi Government said in all today was a successful first day. What we saw was a tightening of the noose around mosul. The worst violence could come when troops reach the builtup areas in the city center. No sign exactly when that could happen. Lester . Richard engel, thank you.
