The republican nomination. But in an interesting twist, more voters would be satisfied in retired brain surgeon ben carson actually wins the nomination over trump. Carson leading by 9 . The mildmannered candidate surprising some by taking a jab at the gop frontrunner wednesday. Going after trumps faith. By humility and the fear of the the lord are riches and honor and life. And thats a very big part of who i am. I dont get that impression with him. Maybe im wrong. Reporter to which trump shot back on twitter. Wow, i am ahead of the field we van gel calls and virtually every other group. And ben carson just took a swipe at me. But carson didnt stop there talking about trumps immigration policy but not mentioning him by name. If anybody can show me how you can actually round up these people who arent necessarily going to be cooperative and how thats not going to jam up the court system and cost enormous amounts of money, im perfectly happy to listen. Reporter trump sticking it to carson, too. He doesnt understand it and hes wrong. Reporter as carson makes gains on trump, a controversial new profile for the billionaire hits newsstands in this issue of Rolling Stone magazine. Trump insulting rival candidate Carly Fiorina watching her on tv saying, quote, look at that face. Would anyone vote for that . Fiorina responding on fox news. Im not going to spend a single cycle wondering what donald trump means, but maybe, just maybe, im getting under the skin a bit because im climbing in the polls. Reporter Trumps Campaign has not commented on the Rolling Stone piece or on fiorinas response to it. Thank you. After mourning in private, Vice President joe biden is in public. He had a meeting with jewish leaders in public and will appear on the Stephen Colbert show tonight. Lets go to jeff zelany following all the latest. Jeff . Reporter Vice President joe biden is traveling to new york for four separate stops today as we works through whether to jump into the 2016 president ial race. And hes going to renew his call to increase the minimum wage and attending a fundraiser for Democratic Senate candidates. And hell appear on the late show with Stephen Colbert. Now i can tell you the Clinton Campaign is watching this with great interest. As Hillary Clinton travels to ohio and wisconsin today to attend fundraisers of her own. But shes also speaking out in strong support of the iran nuclear agreement. Saying in a speech yesterday this president ial campaign has serious consequences. My approach will be distrust and very ify. We should know that iran will test the next president. They want to see how far they can bend the rules. That wont work if im in the white house. Reporter so clinton is trying to put controversies behind her by delivering more speeches like that. And appearing in interviews of her own. She sat down with Ellen Degeneres earlier this week and that interview airs today. One interesting point, she talks about her granddaughter charlotte so often and asked what shell call her. Im fine with grandma and madam president , i mean, whatever. Thats great. Okay, jeff, stay with us because we want to bring in contributing editor for new york magazine, jason engerly. Donald trump is at 32 . Well see what happens, this is with republicans and the allimportant independents. So lets see whats happened in terms of the change between july and now with all the candidates. Donald trump has almost doubled his support. . July he had 18 . Now he has 32 . Look what happened to ben carson, he more than quadrupled his support up to 19 . Everyone else has helded and did or actually fallen somewhat other than Carly Fiorina who increased her support. What do you see, jason . Well, obviously, the republican field is favoring outsiders right now. And that would be trump and carson. I mean, i think that the way trump has just been able to defy political gravity has been fascinating. His inevitable demise gets pushed off. Everybody thought by the end of the summer he would implode. Then later this fall. Now the republican elites are resigning himself to the fact that hell be around in New Hampshire and iowa. Eventually hell falter but they are looking to april, may, june. How do you know hell demise . Inevitable hes falter. He falters plenty. Thats the only thing inevitable, he will falter, but it doesnt hurt him in thele whos. He goes the opposite direction. Weigh in on this, is it time that we have been saying for a while, dont write him off. But in a more profound way, he could be representative of something people want right now. What makes you feel otherwise . Sure. Hes definitely tapping into this interest. I dont think we should write him off, we should write him in. Now hes becoming more of a serious president ial candidate. So everything he says will be looked at in a slightly different way. Those comments about Carly Fiorina, i promise or predict to you that will come back during the debate next week here on cnn. And she can be standing on that stage looking him in the eye and said, donald, you dont like my face. Things are magnified before a big audience eventually will be part of this whole Information Packet that voters have. Some voters wont care about it but some will care about it. The fall always becomes a time for new voters to take a look at the race. So now hes a serious president ial candidate to be treated like one and well see what he thinks about it. Well see if voters care about faith because ben carson said to trump, that trump does not think that trump has humility and that the faith is not a very big part of his life. Does this matter to voters at this point . It doesnt seem like it does so far. I mean, this is not necessarily a new thing to say about donald trump. You know, he clearly doesnt know the difference between the Old Testament and new testament. It seems he likes the art of the deal almost as much as the bible and yet standing among evangelicals as increased. When out in iowa, he basically insulted them and it doesnt make a difference. Jason, if youre dealing with a voter group that cares about their faith and it being taken seriously, especially the bible, we are talking evangelicals here, more than anything else, he is about the opposite of what they would want on paper and yet they are choosing first to synthesize. I think theres something about his willingness to be incorrect. And i think in the poll, the fact that a majority of Republican Voters being concerned about illegal immigration, that has to be of great concern to the rest of the Republican Party. Because i think that even if trump does inevitably falter, he will have changed the shape of the race by forcing other candidates to go through immigration in a way that could harm them in a general election. If i can jump in here for a second, the evangelicals in iowa, this is a big deal. What ben carson said yesterday is going to be the most interesting attack on him. Well see if it works or not, but social conservatives, evangelicals in the Iowa Caucuses, very important. Thats who ben carson was talking to in his speech in california. I think this is one of those that may stick among some of those evangelical voters in the Iowa Caucuses. We should mention well have donald trump on new day at 7 30 eastern. So everyone should stick around for this as we put the questions to him. But also speaking of the positions that voters think are important, well put this up. A new cnn poll out this morning that asks, most important reason why you support donald trump . 21 say on the job experience. They believe hes an experienced negotiator and businessman. 71 say position on the issues. And then look at that, the next one is 5 , dont like other candidates. So its not a protest vote, jason. No, its well, you know, its a protest vote in the sense that the idea that they think he has experience, the issues hes focusing on are not necessarily issues anyone else is focusing on before. I think that you cant say that its not a protest vote in the sense that hes just completely different than the rest of the field in the fact they are gravitating to carson. I get that its not his fellow candidates, like jeb bush, obviously. Jeb bush is saddled with the washington label and saddled with the establishment label. Anyone at all associated with washington and with having been in office at this point. Thats a strike against you. Jason, lets end here with a little politics. At what month do you believe that donald trump will no longer be first in the polls . March. I would say now. March. We have a beer on it. We have to keep politics serious. I have never known to you suggest that. Silver mining. Jeff and jason, thank you very much. So the candidates as part of the cnn commitment to cover the race, well have people everywhere today. As we mentioned, youll get a dose of the donald next hour on new day. You get to feel the burn with Bernie Sanders joining wolf blitzer at 1 00. And jeb, better looking than my brother, bush, speaking with jeff tapper at 4 00 p. M. And tune into the big Republican Debate here on wednesday, september 16, 6 00 and 8 00 p. M. Eastern. And tonight on ac 360 find out which candidates will be on the main debate stage. And well get to other news now. New details emerging this morning in the death of Illinois Police lieutenant joe gliniewicz. The coroner says a single gunshot is what killed him. Reporter good morning, makayla. The lake county coroner is quoted saying lieutenant gliniewicz died from one devastating gunshot wound. He wont go into the details and say how many times, where he was shot, if there were other wounds or even the manner of death saying that he doesnt know where the bullet came from. And also adding, quote, right now all unnatural deaths are up for suggestion. That means homicide, suicide, accident, undetermined. Ive covered a lot of crime scenes and have to give you context here because a few things really standout. First of all, the investigation from the getgo has been looking for three suspects. Very early on in that investigation they stopped doing the doortodoor geographic gridlike search with lots of officers on the ground. Now, after that we have the commander whose in charge flubbing, calling this case first a murder and then correcting himself and saying, quote, im sorry, killed. And then youve got this Surveillance Video that authorities were so focused on saying that it had three suspects. Well, they talked to those suspects and now they say that those individuals are not persons of interest. They are not suspects. And here we are with very little information, chris, and a lot of questions in the killing of this lieutenant. But you got an entire force and really a big part of the city there looking for answersful well stay on this story. Rosa, thank you very much. Also important for you to know this morning, the u. S. And nato expressing renewed and intensified concerns over a Russian Military buildup in syria. Lets get right to pentagon correspondent Barbara Starr with the latest. Reporter good morning, chris. The confrontation essentially brewing between moscow and washington. Secretary of state john kerry now making a second telephone call in a week to his russian counterpart foreign minister Sergey Lavrov asking what the syrians are up to in syria. Theres a lot of concern over the Russian Military buildup. Listen to what the state department has to say about this. It is the true, and if brought out those reports could lead to greater violence and more, even more instability in this area. Reporter now what the u. S. Has been noticing, the buildup is all about, they are seeing russian infantry, Naval Infantry, the equivalent of u. S. Marines going into syria. They are seeing dozens of russian vehicles, some Armored Vehicles beginning to appear on the ground there. Russian transport planes bringing in more and more equipment. What do they think is happening . The u. S. Theory is at this point the russians are building up for possible air strikes against rebel forces challenging bashar al assad, thats exactly not what washington wants to see. They want assad to go. They dont want to see the russians cropping him up and the violence being extended even further. That is so troubling. Barbara, thank you for the update. Also breaking news right now at this hour, theres a desperate rescue underway during an understaprecedented downpour japan causing more than a thousand people to evacuate. Will ripley is in tokyo with the latest on whats happening. What is happening, will . Reporter alyson, two feet of rain since monday evening in parts of japan to lead to what is unfolding right now. The dramatic rescues along the river, these are people who had almost no notice to evacuate from their homes as the waters rose so quickly they had to run upstairs to their balconies and rooftops. Some people were stuck in their cars or clinging to light poles waiting for the Japanese Military to come to rescue them. More than 170,000 people received emergency evacuation orders. Many are staying in some 100 Evacuation Centers set up right now, but what is still unknown at this hour, exactly how many people may still be trapped in some of the flooded out buildings. Some of those buildings we have seen from aerial photographs washed away by the strength of those rising waters. And in near fukushima prefecture, home of the crippled nuclear plant, theres contaminated radioactive water being stored outside that has been spilling at times during this rain event into the ocean. The power provider tepco says there were several tons of radioactive water that spilled over a period of three hours. They say that leak is now contained but they continue to monitor radiation levels in the area which are normal for now. Thank you so much for that update. Well watch with you and let us know when there are more developments. Meanwhile, back here stateside, a Tropical Storm is churning in the atlantic. Rain is expected to hit the northeast today.

It will be shaping up slow across the northeast today if youre traveling by car or rail for that matter. It could be slow because of the rainfall. We are not talking rainfall in tokyo and points north of there, but still significant rainfall. And yes, henri is in the atlantic ocean. So heavy northeast rainfall, two to four inches of rain in some spots. Here we move ahead to 8 00 tonight, the rain continues over the area for hour after hour after hour. This is 2 00, 3 00, 4 00 and its still raining. Two to four inches possible from new york city down to south jersey. Other than that, cold air coming in to feel like fall for the next couple of days as two low pressure centers, two cold fronts really start to cool down the northeast. In fact, well only be in the 70s today and up to 80, well just muster barely 80 tomorrow and even cooler sunday and monday as we move you ahead. Yes, you said henri, i know weve had a slow Severe Weather or circulation season here. Cyclone season and Severe Weather and tropical season very slow this year, but today is the peak of the season.

And when i found out that my daughterinlaw, joyce, cant eat gluten, we found a way to remove the grains that contain gluten, from the naturally gluten free oats that cheerios are made of.

There wont be surprise anytimeanywhere inspections. And after ten years, restrictions are lifted and iran could build a Nuclear Weapon in two months. Congress should reject a bad deal. We need a better deal. And i didnt get here alone. There were people who listened along the way. People who gave me options. Kept me on track. And through it all, my retirement never got left behind. So today, im prepared for anything we may want tomorrow to be. Every someday needs a plan. Lets talk about your old 401 k today. Made a simple tripvere chto the grocery storeis anything but simple. So finally, i had an important conversation with my dermatologist about humira.
