We had our third shottest august on record, george and lara. Wow, a hot day ahead. The race for president now, your voice, your vote and the gloves are off for jeb bush. Launching an allout assault on donald trump after weeks of attacks. Trump is standing by live to respond. First lets get the latest from jon karl and jon, with trump still rising the bush camp making a big and possibly risky decision. Reporter big and risky but jeb bush is way down in the polls and clearly irritated by donald trump. In the war of words between donald trump and jeb bush, Florida Governor admits its getting personal. Its all personal for him, sure. Mischaracterry sayings of my views. Reporter bush is firing back not just in english but in spanish. Accusing trump of vilifying anyone who disagrees with him. [ speaking spanish ] reporter now the Bush Campaign is throwing trumps words right back at him. Portraying the donald as no conservative. I lived in new york city and manhattan all my life, okay, so my views are different than if i lived in iowa. Hillary clinton is a terrific woman. Im a little biased because ive known her for years. Reporter trump hit right back with jebs own words praising hillary. We recognize the commitment of someone who tweeted her life to Public Service and want to say thank you to secretary clinton and president clinton. Reporter the Clinton Campaign chimed in, no need to fight, guys. You both agree hillary was a great secretary of state. We get it. All three may have a larger problem. A new abc Washington Post poll show americans have a negative view of all of them, 53 viewing clinton unfavorably, 55 and 59 for donald trump. Those numbers are just another indication of how unusual this race is. You have Hillary Clinton and donald trump both the clear frontrunners for their partys nominations and viewed unfavorably by a clear majority of voters. And, george, this is before all of those television attack ads that you know will come before tomorrow. This is just the beginning. Okay, jon, thanks very much. To donald trump right now. Still holding pretty commanding lead in the republican polls, National Polls and iowa. Mr. Trump, thanks for joining us this morning. Boy, you heard jeb bush yesterday. Youre not a conservative, youre more democrat than republican. This is all personal. Is he drawing blood . Well, i think he had really no choice. Hes doing very poorly in the polls. Hes a very low energy kind of guy and he had to do something so theyre spending a lot of money on ads and he has a lot of money from the Hedge Fund Guys from the special interests from lobbyists, he raised over 100 million so they control him totally so he really had no choice, i think, george. He had to go out with an ad and did a very expensive ad and lets see what happens. So far everybody thats attacked me has gone down. He also shows you praising Hillary Clinton in the video. Bottom line, who would be the better president obama, jeb bush or Hillary Clinton . Well, i go with the republican. Hillary was absolutely a horrendous secretary of state, probably the worst ever and i would have to go really with the republican. You know, i was obviously very friendly, i was a Major Business person. Youve seen that and i really was very friendly with all politicians. If im in new york i was friendly with politicians throughout the united states. I was friendly that was my obligation. That was my job to do as what they just they turned me into a world class businessman so i had to get along with everybody. I got along with the clintons and everybody and it was important to do so, but now, you know, you look at jeb and see what hes doing and its sort of an interesting thing and i think he probably had no choice. Its probably now going to stop because it seems to be backfiring on him based on the polls, seems to be somewhat backfiring on jeb. In the video it says showed you answering questions saying you have no idea why youre republican. How would you answer that today . Why are you a republican . That was at a time when the republicans were not doing well and, frankly, they had some ideas that were different from my ideas and a lot of people felt that way and many republicans were saying we have no idea why were republicans. The republicans were not doing well. But right now you say you are a republican. You are going to go with the republican nominee and heard you say that about jeb bush. What about ben carson . One poll shows him tied with you right now in iowa. Others have you ahead still. What do you make of the threat posed by ben carson in iowa . Well, i like ben a lot. Hes a good guy but hes been spending a tremendous amount of Advertising Money in iowa and the one poll where we have a tie and the other one im leading by quite a bit in iowa, but one of them came out and a little bit surprisingly there was a tie and i think thats great. But ben is spending money in iowa and im not. I am out in iowa quite a bit and made speeches, quite a few of them and had a tremendous response and tremendous audiences but ben is spending a lot of money in iowa. You said you want to prohibit American Companies like ford from building plants in mexico and complained about china eating our lunch. So will you disassociate yourself from every company that creates jobs i want to prohibit them but create jobs here. We need jobs in the united states, george. We dont need jobs in mexico. We dont need jobs in china. China is eating our lunch, mexico is eating our lunch. We need jobs here. We need plants built right here in the united states. We dont need them built in mexico. We dont need them built in china. That doesnt help us despite what some people will try and tell you that it does. Believe me, it doesnt. Ill have jobs in the united states. Im going to win the hispanic vote because im going to create jobs and ive already, if you look at polls with the hispanics im winning in many polls with hispanics which some people are surprised at. Im not surprised at. But yes or no, will you dissociate from any companies or partners of yours that do business in china or mexico . I wouldnt do that. I want to do business with them. Im a free trader. The problem with free trade you have to have smart leaders on our side. We do not have smart leaders. We do not have good negotiators. Everything we negotiate is bad including the iran deal. That deal is one of the worst negotiated transactions ive ever witnessed in my entire life. Its negotiated by people that are either stupid, incompetent, theres something wrong a deal thats absolutely insane. So we have bad negotiators on that we have bad negotiators on trade. If i win were going to turn it around and bring jobs back to this country and have a lot of convict instead of always losing. Always opinionated donald trump, thank you for joining us this morning. Thank you very much. Indeed, turning now to the kentucky county clerk who refused to issue samesex marriage licenses because of her religious beliefs defying the Supreme Courts ruling.

We should have the same rights as everybody else to walk into that office and get a marriage license. Were equal to everyone else.

Abcs david kerley in silver spring, maryland, with the details. Good morning. Reporter two deaths already, the government is worried about more. So this morning a warning to five Online Companies and already that warning is having an effect. This morning warning letters sent to five producers of powdered caffeine from the fda stating that it is potentially dangerous and presents significant or unreasonable risk of illness or injury. Too much caffeine can cause erratic heartbeats, seizures, even death but its increasingly popular with Young Athletes like 18yearold Logan Steiner who died just two weeks before his High School Graduation after using just one teaspoon. But one teaspoon equals 28 couples of coffee. Who would think caffeine is broken down into such an amazingly deadly, lethal weapon. It is poison in a jar, plain and simple. It needs to be done and rid of, just get rid of it. Reporter the fda claims safe amounts of the powder, 1 16 of a teaspoon are too small to measure. Its sold online. Some in 3. 5ounce packages, the equivalent of 1250 red bulls or 3,000 cans of cocacola. The fda demanding the Companies Respond in 15 days but 3 of the 5 are telling abc news and other outlets they are getting out of the business. They will no longer offer pure caffeine powder supplements. There are two other companies that weve asked for a response, will they continue to sell it . They did not respond. This is a supplement so the fda cant ban it but, george and lara, they say theyll keep the pressure on those two other companies. A lot of scary information, thanks.
