[Victor Blackwell, Cnn Anchor:] Breaking overnight, new explosions in China. Reigniting fires and sending black smoke, again, billowing into the air.
[Donald Trump , Presidential Candidate:] Honestly, I think we are led by stupid people.
[Christi Paul, Cnn Anchor:] How do you really feel? Donald Trump blasting members of his own party and Hillary Clinton in his latest campaign stop, but with all eyes on Iowa this morning, which candidate is coming out fighting?
[Blackwell:] Plus, seemingly a first for ISIS. The terror group using a mustard agent as a weapon and at least one attack in Syria and that has the U.S. and others extremely concerned. Good morning. Good to be with you this Saturday morning. I'm Victor Blackwell.
[Paul:] I'm Christi Paul. Always so glad to have your company.
[Blackwell:] All right, it's said to be a big political day as presidential hopefuls, including a pair of frontrunners, descend upon the Iowa State Fair. Now among those said to attend, former Secretary of State Hillary Clinton, Senator Bernie Sanders and the GOP frontrunner, Donald Trump. Now the mogul expected to make a grand entrance arriving in the G- Trump here, his helicopter. This comes after a big rally in another key state. The first primary in the country, New Hampshire, that is where he took shots at rivals, Jeb Bush and Hillary Clinton. He also gave a little more insight into the policy he might roll out. Joining us now to discuss is CNN's Sunlen Serfaty. Sunlen, what has been the reaction this morning to Trump's speech, a little meteor?
[Sunlen Serfaty, Cnn Correspondent:] That's right, Victor. We talked to a lot of voters here in New Hampshire, who specifically came out to hear Trump speak last night. There was really broad consensus among them. They want to hear more specifics. They want to know what a potential President Trump would do in office and certainly this had been a major constant criticism of Trump and his campaign that he speaks in broad strokes, but he doesn't offer up the policies in specific to back them up. So certainly here this is a big stay tuned coming from Donald Trump. In an interview with "The Washington Post" promising that he will release specific policy papers the first part of September starting with his immigration policy and moving to his tax policy. And this comes at a time where the campaign really seems to be trying to take themselves more seriously and trying to dig in a lot of the early states and notable that also in that interview, Trump is saying he is reaching out to some senators in help in writing policy. Saying he specifically reached out to Senator Sessions as he writes his immigration plan. Here is Donald Trump last night in New Hampshire.
[Donald Trump , Presidential Candidate:] It will be very soon. I have some of the most brilliant people in the country working on tax, which I'm involved in very much because I understand the system very well, probably better than anyone who has ever run for office, if you want to know the truth, because I am part of the system. But we have some amazing people working on immigration, so I would say over the next two or three weeks, probably sometime during the September.
[Serfaty:] Meanwhile, Donald Trump continuing to go after his opponents really not lighting up and honing in on Secretary of State Hillary Clinton and her use of her private e-mail server when she was secretary of state. Here is more of Donald Trump.
[Trump:] I think, at some point, she perhaps is not able to run and have to end her campaign. That seems to be the thinking by so many. General Petraeus, his life was destroyed with a tiny fraction of what he has done. So it's very unfair to him if they are going to destroy him over doing, by comparison nothing, I don't see how she can run. I think she has got much bigger problems than running for office.
[Serfaty:] And Trump does head to Iowa for the Iowa State Fair today and it also comes at a time where the campaign there is really beefing up their staffing during the early state. Victor, another sign that the campaign is moving towards potentially a longer campaign, they are in it potentially for the long haul.
[Blackwell:] All right, we will see. Sunlen Serfaty, thank you so much.
[Paul:] Meanwhile, Hillary Clinton unleashed her harshest attacks on the Republicans yet. In 20-minute speech before 2,000 people at the Iowa Democratic Wing Ding Dinner, Clinton blasted several GOP contenders by name and brought one rowdy crowd to its feet. Listen to this.
[Hillary Clinton , Presidential Candidate:] Now, I know most of the attention these days is on a certain flamboyant frontrunner. But don't let the circus distract you. If you look at their policies, most of the other candidates are just Trump without the pizzazz or the hair. Yes. Mr. Trump says outrageous and hateful things about immigrants, but how many of the other candidates disagree with his platform? None of the leading candidates support a real path to citizenship when they talk about legal status that is code for second-class status. The same when it comes to women's health and women's rights.
[Paul:] Clinton also addressed the e-mail scandal saying she had provided her server to the Justice Department and that she would not play politics with national security. We want to get to the breaking news out of China right now, new explosions rocking that same site where we saw that massive blast that killed dozens of people earlier this week. Flames now reignited, we understand, and black smoke once again in the air. Look at the pictures we are getting here. Will Ripley has been at the site since the first explosion Wednesday. Will, what can you tell us what is happening there right now?
[Will Ripley, Cnn Correspondent:] There have been a lot of developments. Several explosions were heard here prompting the evacuation of this emergency shelter that we have been reporting from. We saw busloads of families with children being taken to a safer location farther away downtown and earlier in the day, we were wearing our masks while reporting here, but just within the last few minutes the government telling us, in fact, the evacuation was false. That the air they say is safe, and even though deadly sodium cyanide has been detected near the site of this chemical explosion along with a long list of other toxic along with some other potentially explosive and dangerous toxins, they say air quality shows things are back to normal here. Although you can see some people are still choosing not to be photographed, but use face masks as well that's a decision we are constantly evaluating. The families of some of the missing firefighters stormed a press conference this morning. We were there and locked in the room by government officials trying to prevent us from talking with these families who say that their loved ones are still missing and they were in the first wave of firefighters. The firefighters who the government now says used water on that chemical fire Wednesday, unaware that water, when being mixed with those chemicals, would create explosions like the ones that we saw here. It seems as if these first responders were unaware of the danger and they were running to try to put out the fire, but by using water, that triggered these blasts and that is where the investigation is taking us right now. As we were trying to report about that very topic earlier from a different location, a plain clothes officer shoved our camera and put their hands in front of it and pushed us into our vehicle while we were live telling us to get out of the way. So it just goes to show, Christi, how China the increasing sensitivity and the suspicions here of some sort of government cover- up, that why was this facility allowed to store these chemicals so close to where families and children were living? Meanwhile, you see people are now returning to this emergency shelter, getting water and other needed supplies. There are still thousands of people who are homeless here right now as a result of this disaster and they are not sure when they will be able to go home Christi.
[Paul:] All right, Will Ripley, great report. Thank you so much. We appreciate the update.
[Blackwell:] Imagine this, a man in New York saw more than 100 patients and had an office, but authorities say he was no doctor. Before he actually was caught, he acted like a doctor for three years! We will tell you how he got away with it. That is still ahead. Plus, ISIS is taking its attack to a new level. More on what the terror group is using that has U.S. military leaders so concerned. And look at this, a volcano erupts, sending ash three miles high and igniting several explosions.
