Announcer from nbc news, this is a special edition of today countdown to rio with matt lauer live from Rio De Janeiro, brazil, and savannah guthrie, live from rockefeller plaza. Good morning, everybody. Welcome to a special split edition of today on a Tuesday Morning. Beautiful shots of rio. Boardwalk just off copacabana beach. Fridays Opening Ceremony just three short days away. I see you with the jacket there. We have to remember, this is winter in rio. It is winter. Were dead in the middle of winter. Temperatures during the day can get up into the 80s when the sun is out. Its a lot chillier today. Probably 70 degrees. Its a little overcast and the wind is blowing. We are along the prominad at copacabana beach. It goes all of the popular place. The beach is right here obviously. But during the day, all times of the day, youll find people here walking, strolling with their kids, exercising. Exercise is very popular here because they all want to look good in those tiny little bathing suits they wear on the beaches and because, savannah, were at the olympics, we sent our researchers and interns and our production assistants out on back any moment now. Meanwhile, coming up, well have a lot from rio including that story you just talked about. Thomas bach commenting on their decision not to ban the entire russian team from these games. You know about sugarloaf, right, savannah . Sugarloaf mountain. Exactly. That iconic granite peak. Hoda and i took a journey up there yesterday. The view is well have that for you as well. Looking forward to that. Lets start with the president ial race. Our new nbc News Survey Monkey online tracking poll following her nomination at the Democratic National convention, Hillary Clinton now leads it. Donald trump, 50 to 42 . Thats a sevenpoint jump from last week. Nbcs Hallie Jackson has the race covered this morning. Shes in columbus, ohio. Hallie, good morning to you. Reporter good morning. That online poll you just bounce now for Hillary Clinton coming out of her convention as her rival, donald trump, faces new fallout today from multiple controversies. He often calls her crooked. Now donald trump has a new name for Hillary Clinton. Shes the devil. Reporter that insult coming as trump slams the endorsement of Bernie Sanders. He made a deal of with the definitely. Shes a devil. Reporter a new fiery attack. The gop nominee not backing off criticism of the khan family whose son was killed in iraq. As far as im concerned hes a hero. Horrible things were said about me. Reporter trump later adding the son wouldnt have died because i wouldnt have been in the war if i was president back then. Reporter the gold star parents keeping up their own genuine patriotic american falling in his trap. Hes a snake solesman. Reporter another military mom confronting trumps vp. Mike pence forced to defend his running mate on the campaign trail. The last 24 hours have seen responses. Almost all praising captain humayun khans service. John mccain said trump doesnt have an unfettered license to defend those who are the best among us but mccain and other republicans still not unendorsing the nominee. I support the nominee of the party. I would not have said what he said in the way he said it because the family had a right in. I mean, is there no limit to which this guy will descend . Reporter all this as clinton faces her own controversy over her emails. Fact checkers giving their worst rating to her response to this question on fox news. Fbi director james comey said none of those things that you told the American Public were true. Chris, thats not what i heard director comey say. Director comey said my answers were truthful. Reporter clinton getting backing from billionaires like Warren Buffett laying down a challenge to trump. Release your returns, buffett said. Im under audit, too. There are no rules. Reporter heres Something Else making headlines for trump this morning. His comments to a usa today columnist about the Sexual Harassment complaints against fox news roger ailes. That ailes allegedly behaved. I would like to think ivanka would find another career or company if that was the case. As an author points out, most women arent able to quit her job and why a woman should upend her career because she ended up in the crosshairs of some harasser. Hallie jackson on the trail. Thank you. Lots to talk about with mark halperin. Good morning to you. Trying to figure this donald trump. This story has been kept alive for four days. Is this strategy on his part or has he lost control of this . I think about president george w. Bush who received this kind of criticism from many people including Cindy Sheehan but he didnt engage with Cindy Sheehan. He disagreed with that criticism but didnt attack her. I dont understand what trumps strategy is. You would be in the same place as a lot of republicans no one has ever behaved quite like this in president ial politics. Hes gone after people before in the past. John mccain and others and succeeded by showing strength but hes chosen to keep up a long running battle with the most sympathetic people you can imagine, gold star families. Pushing off otherwise negative stories about Hillary Clinton that may lead all of the headlines. Greatest frustration for republicans who want him to win is you have the remarks that ha Hillary Clinton talking about the fbi investigation where she clearly wasnt accurate. Youve got gdp growth numbers. Sluggish. Weak economic numbers for the incumbent party. A lot of republicans are wonder why donald trump continues to fight with the khan but why isnt he focusing on these issues at a time when he did not get as good a convention bounce as Hillary Clinton did. Meanwhile, you have Top Republicans like speaker ryan, senator mcconnell, john mccain, attack on the khans personally and khan service. You dont see them rescinding their endorsement of donald trump. Do you think pressure is growing on them to do so . You dont see many of them on camera saying things. This is an uncomfortable situation for republicans. You have lots of family members im hearing of prominent republicans, sons and daughters and spouses saying this is not good. This is not the right way. You should consider unendorsing. I think most of them want to wait for the first they still feel their electoral fate is tied to donald trump. If they enunendorse, theyre worried the whole party goes down. Polls dont look great for him right now. Still close enough they hope that he can come back and party can be unified in the fall. He made that intriguing comment yesterday about the system being rigged. Some people interpreted that as hes laying the groundwork already that if he loses he can say, well, there was something unfair about the process. He wants to have a hedge against the loss to say i couldnt win because the system is rigged. Its bad for the country. We need bipartisan, nonpartisan sense that elections are fair, the kind of chaos that donald trump sows may be about himself and not good for the whole country because this election is going to be hotly contested. Lets move to new cases of zika leading the cdc to issue an historic whatever they can to stop that virus from spreading further. Nbcs Kerry Sanders is right there in the thick of the battle. Kerry, good morning. Reporter good morning, savannah. These are the weapons of war. An airplane that flies late at night, early in the morning, just down over neighborhoods skimming the neighborhoods, letting out a thin mist of insecticide and also fogger mosquito control. The fear is what looks like a one square mile of miami could spread if the mosquito population is not squashed immediately. This morning the streets of this popular miami neighborhood filled with clouds of insecticide. An urgent allout counter attack. The enemy, mosquitos carrying the zika virus. Were very active in making sure we do everything we can to control the spread of zika in our Health Officials with an extraordinary warning. Pregnant women being advised to avoid miamis artsy windwood district. To be safe pregnant women shouldnt travel there and if pregnant women live or work there, they should do Everything Possible to prevent mosquito bites. Reporter florida officials now rushing in reinforcements. An Emergency Response team from the cdc. Alarm bells going off after the number of zika cases from local mosquitos more than tripled from obviously the apparent connection. Reporter many patients are scared. Now that it hit home, were extremely concerned about the zika virus. Reporter growing concern throughout florida that fear of zika will put a damper on the states crucial tourism industry. While officials worry zika may ad still has not. You didnt even know . No. Reporter are you concerned now that you hear that . Im not pregnant. Right now im here. Im already here. Were not leaving. Reporter the fogger trucks and airplanes that are laying that insecticide down also have another problem and that is rain, which dilutes the insecticide and its that rain that creates puddles where the mosquitos breed. Night. Savannah . Kerry, tough situation down there for sure. Thank you so much. Doctor, good morning. Were at this moment that Public Officials have been warning about and worrying about where we have locally transmitted cases the zika. What are the chances that it really can be confined to just this small little area . The issue is this. What weve always banked on is that the urban infrastructure in or allow the epidemic to grow the way it has in south america and latin america because part of the advisement and guidance has been stay inside, stay in air conditioning, use your screens. Theres a lot more information. More education about this. We have some of the preparedness but some of the concerns in the last 24 hours is the insecticide working . Remove standing water, it can grow eggs in the size of a bottle cap. Its a challenge to say the least. I wonder why the warning was confined to just this neighborhood. I get thats where we know for a fact the zika mosquitos are but its not like mosquitos observe borders. Why not make it bigger in an abundance of caution . I think the answer lies in that this is an actively Ongoing Investigation and surveillance. I think the guidance as we will fairly rapid basis. As we discussed earlier, the mosquito itself doesnt travel that far. It has a narrow spectrum where it can travel but human beings hijack the bug and start traveling and where were concerned about the threat. Thats a question we were talking about ever the show. How is it transmitted . Does it go from mosquito to mosquito . No. It goes from a mosquito thats infected, bites a human being, bitten by another mosquito and the human being is the host transmitting it to the mosquitos. The mosquito doesnt transmit to another adult, it lays eggs. Thats how generation to generation the mosquito population can get out of control thats infected with this virus. Thank you so much. Lets head back down to rio and matt. All right. Thank you very much. More and more athletes, more and more spectators arriing every day wh now just three days away.
