We begin in michigan where republican president ial candidate zain is grinning already. Donald trump is back on the campaign trail. How could you not grin . This come as trump tops two polls in the early voting states of New Hampshire and iowa on the heels of last weeks debate. On tuesday, he gave his first speech since the gop debate and of course the controversial comments he made about debate moderator and fox news anchor megyn kelly. Before he speech, he boasted about how much support he had from key demographics, including women, hispanics and took aim at another republican contender, jeb bush. Listen i think we will do well with the hispanic and women vote. If you look at nevada, they did the poll and im leading in the hispanic vote because i create jobs. I will be creating tremendous numbers of jobs. I think we will do great. The Womens Health issues, im for that. I watched jeb bush give the worst answer the other day. I think thats going to be his 47 . Romney possibly lost the election for a lot of reasons frankly that he lost, but one of the big reasons was his 47 . That was a disaster. I think jebs answer the other day on Womens Health issues is a disaster for him. Hi then went and said he misspoke. How do you misspeak about that . I will be great on Womens Health issues. I cherish women. I will be great on Womens Health issues, believe me. Sara murray is joining us from birch run, michigan. You were there listening to what donald trump had to say. At this stage the electorate is looking for specifics from the republican front runner. Lets listen to what he said about the womens issues. I go home and see my wife, e melania, she will make a beautiful first lady, she has a great heart. She cares more about those women issues that i bush doesnt care about that. Between her and ivanka, believe me. So essentially saying, hey, women in my family care about womens issues. Im wondering if women were impressed by this . We are talking to women here. I they felt like the idea that donald trump was struggling with female voters was overblown. This came about after the Fiery Exchange with megan dela megyn e debate stage. This is sort of politics as usual. They werent holding it against him. None of the people i talked to said they felt like donald trump would be with the kind of president who was harmful to women. That was interesting to hear. He continues to be the teflon don. Controversies do not stick to him. Another issue, trump mentioned he is winning withing the latino vote in nevada, that is true according to a poll there but trump mentioned he leads only among republicans. Hillary clinton in the same poll is favored by hispanics by 20 percentage points. Im wondering if the party in general is worried that a trump nomination may hand it to democrats. It is true that they have struggled with women and hispanic voters and we have heard criticism saying if we want to be serious, trump is not the guy to do that. It is interesting to watch trump turn that around. Hes been trying to turn the womens issue around on jeb bush for instance. We will see how successful that is for him. Theres real concern within the Republican Party that donald trump is not the face they want to put if they are going to improve their appeal to female and hispanic voters. Some think he could undermine the progress. In many ways he fact he is not a politician, hes different, the rules dont apply to him is almost his appeal. What do attendees think of what he had to say or do you get the sense he is in awe of the celebrity because he is a big star in the states . Lie like the idea he does not talk like a politician. They find it refreshing. It almost makes them more willing to give a pass. When you ask why doesnt ve offered more specifics on policy, and do you think it is time, they agree it is time but they are not angry for him doing it up until now. They say hee needed to get to our attention and now he has it he is moving to the next phase of the campaign. They want to hear details but more patient with the idea that trump is not the usual politician. Not your typical campaign and may not be hitting the normal milestones we may see from a traditional candidate at this point. Fascinating to watch. Well continue to wonder what donald trump will do next. Sara murray joining us from michigan, thank you very much. Thanks. Interesting, even though he hasnt outlined clear policies people like the way he talks. He is direct, says exactly what he thinks. Theres value in being a strong communicator. Even though he hasnt offered specifics for a large percentage of republicans it is enough and they believe he can get things done. When he makes the speeches it is a stream of consciousness. Former Florida Governor jeb bush was on the podium on tuesday outlining his plan to fight isis and islamic extremism. He spoke to supporters on tuesday in california at the Ronald Reagan president ial library. Are here are some specifics. He said he would impose a nofly zone over syria and embed u. S. Troops with iraqi forces. He took aim at barack obama for pulling combat troops out of iraq he says too quickly and not having a strategy to fight isis. They are pursuing a minimalist approach of incremental escalation. The results have been a creeping u. S. Involvement without any strategic results. The worst of both worlds. A year of limited strikes and other half measures has made little discernible difference the sum total of the isis danger. A halting, ineffective effort against them has only emboldened these terrorists leaving the pandemic unchecked. Hillary clinton will hand over her private email service to the server rather to the u. S. Justice department. She used it during her time as secretary of state. And has faced intense criticism for not using a secure government server. The fbi opened an investigation. Hillary clinton said she turned over all of her workrelated emails to the state department. Until now she wouldnt turn over the server itself. The majority of respondents in polls dont think she is trustworthy. Im joined by someone who has covered a lot of our president ial campaigns. Thank you for being with us. You are live in los angeles. Ron, Hillary Clinton had previously said that she wouldnt hand over her private email server to the justice department. Whats behind the sudden change . Why now . They are facing really steady relentless pressure on this. She had wanted to maintain control and privacy and what happened is it has become an enormous level of disclosure of her emails and controversy that is unprecedented for a former secretary of state and for a president ial candidate. I think this was an indication of the kind of pressure she faces on this issue. Trustworthiness as been a major issue for Hillary Clinton. While i have you, i want top talk about donald trump. We heard him speak a few hours ago. He said he wants to run as a republican but he will keep the door open to being able to run as an independent. How much of this is him sort of trying to have leverage over the gop . None of us can peer far in to the future of donald trump. It is something i think she deciding minute by minute if not second by second. But it is a threat. In the sense if he chose to run as a Third Party Candidate he would be an enormous challenge for the push can party. His support is concentrated on the elements of white america, particularly blue collar white america. Those are the voters that have become the corner stone of. It is hard to imagine any republican nominee being able to survive, i think, a donald Trump Third Party candidacy. Its not easy to do. Difficult to get on the ballot in all 50 states. Rules conflict and vary state by state. Some say if you run in one party you cant come back in the general. But someone with his money could cause a lot of mischief for the Republican Party if he chooses to go that route. While i have you, i want your reaction to a comment that donald trump made about illegal immigration listen to this. Other countries are sending over people they dont want. They dont want to use their prisons. They dont want to use it. They say why should we use our prisons, for many, many years to house really bad people when the United States will do it . So listen to, the facts dont support what he is saying. Immigration has increased since the 90s but crime has gone down. How does donald trump get away with saying these things without alienating the hispanic community. He has alienated the hispanic community. Too late. Okay. Thats not who he is talking to. There are impact of not only illegal and legal immigration. Half of all republicans in a poll, and a quarter of democrats, growing number of immigrants has threaten traditional american values. You know, this school year that just finished was the first time in American History the majority of our students nationwide were nonwhite, kids of color. Its a different country than when reagan was president. Strump striking a nerve with them. That segment is not big enough to win the primary or general election. The challenge for republicans is how do they satisfy the voters central to their coalition without alienating the growing segments which are Tipping Point voters if a president ial election. The reason why democrats have won the popular vote in five of the last six. Those controversial comments do not seem to be hurting donald trump. We saw the iowa poll and New Hampshire poll as well. Thank you so much. Always a pleasure. Thank you. The top u. S. Diplomate is warning if Congress Rejects the iran nuclear agreement, the world currency could be threatened. Kerry argued the u. S. Would have to impose sanctions on anyone doing business with iran Going Forward and that could result in retaliation. Currency experts dismiss it as rhetoric. Kerry said it makes it impossible for iran to develop the Nuclear Weapon without detection. Listen. Iran could not possibly create, according to tour Intelligence Community and our energy department, they cant create an entire secret, separate fuel cycle track, not doing bt without being detected. I cant tell you that iran might not decide in 15 years lets try to break out. What i can tell you is if they did we will know it to a certainty. Congress has until september 17th to act on that deal. In the meantime we are following breaking news out of china where the country has devalued the currency for the second day in a row. The peoples bank of china set the reference rate 1. 6 lower today. Look at how chinas Financial Markets are responding. Are they rebounding . It seems as though the shanghai composite is. 45 percentage point and hang seng back 1. 75 there. Bring in Financial Consultant from beijing to discuss why this is being done. What is the Chinese Central Bank saying is the reason behind this devaluation and what else are some of the suspicions . Errol, the central bank, of course, saying this is long overdue. The currency which before tuesdays announcement was only allowed to fluctuate within a narrow preset band set by the central bank. That value had been deviating for some time. Thats why they said they did it to have the Exchange Rate more reflective of the reality. If you ask other people the government is doing it to weaken the currency intentionally to help eck porters, especially because tuesdays announcement came days after weak export date was announced by the government. This is now the second largest economy of the world, china. China also is a Major Trading partner of many, if not most, economies of the world. This decision, of course, has been sending ripple effects throughout the world. You mentioned donald trump, he mentioned the chinese currency devaluation in a speech in michigan. This is not new. Many politicians in the u. S. Long accused china of keeping the currency artificially low to help its exporters. The government says no. We are doing it to make it more market based. In a strange way, the Chinese Central Bank has just given donald trump a bit of legitimacy today. Im not sure what that means. Thank you for that update live from beijing. The devalue situation could have some ripple effects in terms of trade and the Global Financial market as well. Cnn anchor Richard Quest explains why it matters. Reporter when you look at how the yuan moved you see all of these effects, whether it is going up or down f. This case obviously it is falling. Meefdly we see the dollar getting stronger. That means more exports from the United States. They become more expensive. Clear negative. Chinese goods, they of course become cheaper which means a more competitive battle. In the short and easy terms, devaluing the yuan is bad for u. S. Exporters and brilliant for chinese export ers but theres more to it than that. You have to look at other currencies tied to the yuan that are losing value, australian and new zealand dollars and brazil. They were all down. They were down not only because of the technical effect but because commodity prices. They are priced in dollars. Those countries are big commodity exporters. Oils, minings, metals. They are all losing ground. At its most simplistic, you can see the yuans move in simply chinese versus u. S. Export 0s and the rest of the world. In the wider picture, over the longer term, you are left with the conclusion that there is a much bigger political play underway. Richard quest, cnn, new york. We will keep our eyes on that. In the meantime we will take a break here on cnn newsroom.
