All eyes are on the olympics opening up in a couple of days and the Opening Ceremony, well, there is a lot of concern about how the conditions are shaping up there. Well have except yours. You know what, i survived sochi. I can survive rio. Well figure it out. Another word for you airbnb. That is coming up. But first breaking news. Crash landing at one of the worlds busiest airports in dubai. You can see the jetliner there engulfed in smoke. 300 people evacuated. And our aviation correspondent david kerley is tracking all the latest. Good morning, david. Good morning, george. This was a troubled landing. Something went terribly gone. Part of the plane explodes. Caught in dramatic moments. Just after it crash landed on a runway at Dubai International airport. Whatten explosion. This is a Dubai International airport. The fire, smoke and explosion leading to emergency chutes being deployed. The explosion coming right after the jet came to rest on the runway. It appears to be sitting on its belly. The airplane has not said if there was an issue with its landing gear. Everything sounded normal. Hello, emirates 521. 521, good afternoon. Reporter the largest carrier in the middle east was flying from india to dubai and the flight path appears completely normal. So the question this morning what happened in those final seconds and on the runway that led to this horrifying explosion. Remarkably emirates is saying this morning, no one was hurt. Its remarkable after that explosion. Crews are trained to evacuate aircraft as quickly as possible to get away from the remaining fuel on board. Now to the race for the white house. And that new trouble for donald trump. The republican nominee going headtohead with top members of his own party as president obama calls him, quote, unfit for the presidency. Abcs cecilia vega has the latest. Good morning, cecilia. Reporter robin, good morning to you. What happened in the last 24 hours for donald trump reads like a checklist of political donts. Hes managed to anger party leaders, anger vets, even moms with babies, yes, babies. Donald trump may be the republican nominee but this morning he is at war with his own party, not just refusing to endorse two of the gops highest ranking members in their state primaries, House Speaker paul ryan and senator john mccain. You know, never been a big fan of john mccain and i just hate the way our veterans have been treated by john and other people. Reporter trump also coming under fire for this move at a virginia rally. A man came up to me and he handed me his purple heart. Reporter trump who never served in the military then said i always wanted to get the purple heart. This was much easier. Reporter he even raised eyebrows for booting out a crying baby. At first saying dont worry about that baby. I love babies. I love babies. I hear that baby crying, i like it. Reporter but then actually i was only kidding. You can get the baby out of here. Thats all right. Dont worry. I think she really believed me that i love having a baby crying while im speaking. Thats okay. Reporter this morning, two highprofile republican supporters announcing they will not vote for trump. Hewlettpackard Ceo Meg Whitman and new york congressman Richard Hanna both saying they will break ranks and support Hillary Clinton. Overnight, ivanka trump forced to defend her fathers comments on Sexual Harassment after he said if his own daughter faced harassment she would find another job. I think Sexual Harassment is inexcusable in any setting. Reporter president obama also piling on with his strongest attack yet. Hes woefully unprepared to do this job. Reporter suggesting gop leaders should withdraw their endorsement of trump. There has to be a point at which you say, this is not somebody i can support for president of the United States. There has to come a point at which you say enough. Reporter well, so far none of the gop leadership is defecting as a result of that call from president obama, but we do now know that overnight rnc chairman Reince Priebus called donald trump to express frustration with how his campaign is handling its messaging and now the Clinton Campaign is pouncing making a concentrated effort to target republicans and pick up some of these votes, george. So much going on there, cecilia. Lets talk about it now with our political analysts jon karl and matthew dowd and let me begin with you. We say this a lot. Weve never seen anything like this. But you have panic at the top ranks of the Republican Party. Trump seems to be at war with the entire party establishment. Right now, and youre reporting something startling. Senior officials inside the Republican Party actually exploring what to do if trump drops out. This is absolutely unprecedented. First of all, i am told that rnc chairman Reince Priebus is furious, that he has had multiple discussions with trump telling him he needs to drastically change course. But heres the news, i am told that senior officials at the party are actively exploring what would happen if trump dropped out. How to replace him on the ballot. The answer, george, is they cant force him out. He would have to go out voluntarily, and then it would be the 168 members of the rnc through a complicated process that would pick a new candidate. It would have to happen by early september. But they think thats a real possibility . He is so unpredictable right now. He is so they are so unable to control his message that they just dont know and they clearly think it is a possibility which is why theyre looking at these rules. So, matthew dowd, lets look at the calculation for these other republican leaders. So far paul ryan, even though hes not endorsed by donald trump, john mccain meeting with mike pence overnight, the Vice President ial candidate, but not rescinding his endorsement either. At what point do the calculations change . Well, i think thats a really good question, george. I think first of all there is a question of principle. Is this the candidate they want to stand by in the course of this as a principled stand and they seem to have answered that already, which is yes. I think, at some point if he deteriorates, lets keep in mind hes still within shouting distance of Hillary Clinton after all of this. We havent seen the results of the last 24 hours, but, george, donald Trump Reminds me of the movie tin cup where the Kevin Costner character keeps dropping the ball and hitting it in the lake and he ends up with a 13 on the hole where the crowd is watching. We are watching this unfold in a way weve never seen before. One of the reasons, jon karl, some of the republicans Still Standing by trump, it appears that he still has some ability to raise some money for them. He does and, george, i have to say the frustration is especially deep because they believe that Hillary Clinton looks vulnerable, exactly as matthew said, shes actually had a bad few days, the dnc has gone through a whole shakeup. She misstated what the fbi director said about her emails. One top official told me if trump had gone on vacation for the past two weeks, he would be in the lead. But, yes, he can still raise money and he still has support among the republican rank and file. This does appear to be masking Hillary Clintons weaknesses, matt. It does. You have two flawed characters, two candidates in the course of this with the highest unfavorability rating weve seen in a president ial contest and an environment that actually helps donald trump. I think thats what most frustrates republicans in this. They think this is the perfect time to capture the white house and they have somebody that keeps committing pilot error in the course of this day in and day out. Okay, matthew dowd, jon karl, thanks very much. Lets go to robin. All right, george, now to the monsoon in the southwest. Flash floods sparking hundreds of evacuations and water rescues. Ginger, of course, is here with all the latest on that. Hey, good morning, robin. Phoenix, arizona, averages about an inch of rain in the entire month of august.

Weve heard about with other nations.

Reporter while others have highlighted exposed wiring, leaky pipes and clogged toilets. To make matters worse, security is also a concern after the Australian Team was robbed during a fire.
