A burglar breaking into a house then this happens. An 11yearold home from School Coming facetoface with the intruder. My heart started pumping when i saw him. And cruel hoax. Was one of the biggest stars in the word, maroon levine, the victim of a vicious prank . Victim of a vicious prank . An anonymous caller claiming he was abusing his supermodel wife and 4weekold daughter. The investigation this morning. And we do say good morning, america. Great for us to have david muir with us. Great to be here. Are you ready for the final one . The last one has arrived. Less than three weeks to go until election day and americans say it doesnt get here quickly enough, right . Take a live look at the debate hall at the university of nevada. Donald trump, Hillary Clinton as robin mentions about to face off there for the final time tonight. One last time and the president theyre looking to replace had his final state dinner overnight and look at Michelle Obama there shining and looking amazing in that versace dress. Well have much more on that coming up but first we want to, of course, get to tonights showdown. The stakes extremely high especially for donald trump. This brandnew poll shows him trailing Hillary Clinton by nine points. As you can imagine, we have Team Coverage this morning, abcs tom llamas starts us off in the debate hall there in las vegas. Good morning, tom. Reporter robin, good morning to you. The tensions so high at this third and final debate, the protocol may actually change. Traditionally the families of the candidates come out from opposite ends of the debate stage so they can cross the room and shake hands in the middle but according to the New York Times the Clinton Campaign has requested that they change this, that the families come out as close to their seats as possible and this is because of the penchant of donald trump to have stunts pulled off in the middle of the debate hall to humiliate the clintons so we may skip altogether that famous handshake. This morning, donald trump with another ace up his sleeve. Inviting president obamas half brother, malik, to be his guest at tonights debate. Tomorrow night is going to be interesting. Reporter malik, who lives in kenya, but it a u. S. Citizen is a trump supporter, and clashed with his brother and Hillary Clinton over their policies. At the last debate, trump had bill clintons accusers sitting right in the debate hall. Thats where malik will be tonight. The new psychological warfare comes as sources tell abc news trump will be aggressive in his approach tonight similar to the last debate. Trump already criticizing clintons stamina. Now she has to do debate prep for five days, right . You know what the debate prep is . Its resting. Its lying down going to sleep. Reporter but while clinton prepares, president obama is taking on trump. I have never seen in my lifetime or in modern political history any president ial candidate trying to discredit the elections and the election process before votes have even taken place. Reporter the president taking issue with trumps talk of a rigged election. But they even want to try to rig the election at the polling booths where so many cities are corrupt. You start whining before the game is even over, whenever things are going badly for you and you lose, you start blaming somebody else, then you dont have what it takes to be in this job. Reporter now donald trump is expected to be in debate prep all day today and lately hes ramped up his attacks on Hillary Clintons health and her email server and, david, we expect that to be a big part of his strategy tonight. David . The only time when the hall is going to be quiet there right behind tom llamas. Now to Hillary Clinton. You heard donald trump criticize her for being off the trail for prepping for the debate but her team says it works. They say just look at the last two debates. Lets get right to Abcs Cecilia Vega live in las vegas this morning with new reporting on clintons strategy going into tonight. Two big issues, they say, shes going to go there . Reporter yeah, they sure do. Two issues in the headlines. Here they are, his claims of a rigged election and, of course, those women who have come forward to accuse donald trump of sexual misconduct. She has yet to actually take him on directly on those two fronts and we expect her to do so for the very first time in here tonight. Also were told shes been preparing to answer questions about those hacked wikileaks emails. We expect her strategy, though, to be to turn it to russia which, of course, is behind the hacks. We also know she is planning on a big head game in this hall tonight. She is bringing two guests of her own, reality tv star billionaire donald trump nemesis mark cuban and meg whitman, hewlettpackards ceo, a bigtime republican supporter of Hillary Clintons. Both of them will be in this hall tonight. Back to the argument from trump turning this back to stamina. These several days of debate prep, but shes had an answer for that. Before saying youre right, i did prepare. She seems to think this really works for her. Reporter yes, she says preparation is key to her performance on that stage. Not just that, her aides say it has paid off in the polls post debate that shes seen a bump but take a look. We crunched the numbers. Donald trump has held more than twice as Many Campaign events as Hillary Clinton in the last few months, 81 to her 32. We expect him to bring up this issue of stamina on the stage in here tonight, david. Well see you in prime time. Thank you. Tonights debate, of course, is the last big chance for these candidates to shape this race so lets bring in abcs jon karl who is also there in las vegas with a look at the latest polls heading into this showdown. Now, before we get into the polls, lets talk about Something Else here. Because wikileaks emails expected to be a hot topic in tonights debate. And you are learning that theres a warning to trump from a Top Republican about this. Reporter yeah, this is significant, robin. Marco rubio, senator marco rubio says these are stolen emails hacked by the russians and that they shouldnt be used. This is what he tells abc news, these leaks are an effort by a Foreign Government to interfere with our electoral process and i will not indulge it. Further, i will i want to warn my fellow republicans who may want to capitalize politically on these leaks. Today it is the democrats. Tomorrow, it could be us. So rubio says trump should stop talking about the Wikileaks Revelations and that he will do so himself. That warning is raising a lot of eyebrows so lets get to those allimportant polls, especially in the battleground states. Where do things stand there and what issues seem to be really be resonating with voters there . Reporter well, the big picture across all these battleground states is you see real momentum for Hillary Clinton and a downward trend for donald trump. But lets look at three of the states remaining really close. The first is ohio. This is probably the best battleground state for donald trump. Up 48 44. The big animating issues here are trade and the economy. Thats where trump has the advantage. Of course, he wants to rip up some of those trade deals, tougher negotiation, that message is resonating in ohio. In florida, you see the mirror image. You see Hillary Clinton on the rise and in florida, what were seeing in the polls is that experience and Foreign Policy are the top issues and that voters are giving Hillary Clinton an advantage there. And then finally right here in the state of nevada this is very much a battleground state, a tight state if you look at this, 46 44 in the latest poll thats within the margin of error, slight lead for Hillary Clinton. The animating issue here is immigration. Of course, donald trump wants to build that wall. Hillary clinton has the opposite position here. She supports a path to citizenship for the 11 million or so undocumented immigrants in this country. The difference couldnt be more stark. A lot of hispanics in this state, and that is advantage, at least so far, Hillary Clinton. It does appear that way, all right, jon, busy day ahead for you and night as well. David. In the meantime, wont have our Powerhouse Political Team with us here on the desk. Martha raddatz and matt dowd. Huge stakes for both donald trump and Hillary Clinton tonight but first donald trump, matt. We saw the stunt before the last debate. He was there with women who accused bill clinton in the past. Moments before the debate, they were all sitting there during that presser. Now we hear hes bringing president obamas half brother. The question is does this work and what does donald trump really have to achieve tonight . First, dont you guys feel biblical with martha and matthew and david . Very biblical table here. Very good day. No, they dont work. I mean theres something for us in the press and people to talk about and say, oh, isnt that interesting . It doesnt work for Hillary Clinton or donald trump. I mean its a Perfect Place to do it is las vegas to have a stunt. Now if they showed up with celine dion it might have impact but these dont matter. What is going to be trumps strategy and what do you make of rubio suggesting that he stay as way from wikileaks . Well, i actually think i totally agree with marco rubio in this. Its stolen information, private information and republicans are in a hypocritical place when they use it because it undermines our democracy and hes right. It undermines our electoral process. I think donald trump has to win and he has to win big tonight. Hes behind as weve seen in the polls and all the key states and nationally in this. He has to change the dynamic of this race and the only place he can do it from now until election day is tonight. How aggressive do you expect Hillary Clinton to be . I expect her to be assertive but not aggressive and we were talking, robin, before, the worst thing she can do is go into a prevent defense because as we know when you do that you start giving up points. You have to play to win, not play not to lose. Now, david and martha i was just going to say that, really. You stole my sports thing. Martha, you and david, you both have moderated debates. Oh, yes. So much has been made about the body language. They didnt shake hands. Donald trump following Hillary Clinton around the stage so what do you think we can expect tonight . Well, i think we have no idea. When i sat there for the last debate and watched them come out and they didnt shake hands, michael, i thought, oh, boy, were in trouble because all that matters and thats the optics of all this and people look at that and very from the getgo when they looked at each other and did not shake hands, that was something. The body language, you could just feel it in that debate hall. Im looking at these debate hall pictures and just sort of having memories of being terrified and on the spot there but him walking around, you could just feel it and you know its a little different on television than what you feel in the room but it was probably even bigger on television. Its going to be a little bit different, and this is not a town hall tonight. Not a town hall so they have to talk just to each other so they cant walk around and they will probably just stay behind the podium. You were amazing, by the way. Even on snl their portrayal of you, i loved it. They were amazing on snl. They nailed it. It was a good martha. Quick question for you, matt, though. On Hillary Clinton you hear the stamina argument from donald trump. Her taking several days off to prep. Take a look at in this morning. All the debate prep. Listen to this. My vision of america is an america where everyone has a place. Literally using her words, theyre trying to get under his skin with her preparation. I think she has been really smart in this preparation. If you think about it this way, donald trump is in a series of rallies basically totaling 200,000 people. These debates will have an audience of 200 million people. So if you want to be game on, you want to be game on when the largest audience is there. When the lights are on. Great book ends, dont you think . It was fun. And the final president ial debate as you know is tonight. You can see it right here on abc. David will be joining george who is anchoring our live coverage with our entire Political Team starting at 9 00 p. M. Eastern time. Well, you know what . Heat of the debate, now theres heat here in times square, and millions of people on the east coast are feeling that heat, and ginger, you have incredible images of fog thats been rolling in. Right. As so many of us were baking in the 80s, even in southern new england. Look what it looked like downtown boston. They struggled to get out of the 60s thanks to that onshore wind. I was stalking their page and saw this. We put a time lapse to showcase how that can change so quickly. So many of us could break or see a record again. You did it yesterday from t all you did it yesterday from texas all the way up through new england. Montgomery, alabama, went to 92, newark, 85. Not reserved as far as records go to right here. Check this out. The ridge stays in place. We could see records break again from atlanta to washington, d. C. But it doesnt last long. There it goes and back to reality even below average for some. By the time we get into the weekend, guys. Thanks so much. See you in a moment. The other news, a frightening scene at a San Francisco high school.
