Now theyre telling their story only on gma. We do say good morning, america. Thank you for joining us on this september 11th. Were marking, 18 years. Its been 18 years since those devastating attacks that caused so much loss as you know, but also really brought out the best in so many of us. It really did and Memorial Services, they are taking place this morning from ground zero here in new york, to the pentagon and shanksville, pennsylvania. Were going to have much more on that ahead. So much more ahead. But also this morning, were live in houston, of course, gearing up for that third democratic debate and george is already there. Good morning to you, george. Good morning, guys. Down here in texas, southern university, michael, you know it well. Its your alma mater, were here in the health and Education Center but its a little dressed up for tomorrow nights debate. Take a look behind me. 3,000 strong will be watching tomorrow night. Ten candidates on stage. The top ten candidates meeting facetoface for the first time in a single night. Thats tomorrow night at 8 00 and coming up here, our brandnew poll which shows where the race against President Trump and some of these Top Democrats stand. Some surprising results and more on that white house shakeup. Well get back to you in a moment. Proud moment for tsu. Oh, yeah, go, tigers. Thats right. Well get to that ahead, but first, we want to get to the breaking news overnight. At least 11 reported tornadoes hitting wyoming and south dakota. Take a look at these images. This is sioux falls. A twister leaving a trail of destruction. Ginger starts us off with the latest. Good morning, ginger. And we are so fortunate, robin, that those images did not come with any serious injuries. Really a miracle because there were 11 reported tornadoes as you mentioned. One in wyoming. The debris starts flying. This was a very powerful day. This morning in sioux falls twohour delays for schools and they are asking people to shelter in place. They have had flash flood warnings and the threat is not over today. Oh, it hit something. Reporter tornadoes ripping through wyoming and south dakota. This is circulation. Reporter 11 reported tornadoes including an overnight twister in sioux falls. And it sounded like a Freight Train going over the house so i got up, dashed into my closet. It felt like the roof was going to come off. Reporter the likely tornado shredding this advanced auto parts store. Winds gusting 70 miles an hour plus, heavy rain, lots of lightning. Reporter electrical wire, insulation, all falling out of the walls hanging from the roof of a best buy. Its scary. Reporter the storm even blowing through the glass doors of this hospital. So much debris littering the roads the city is asking everyone to stay in place this morning until they can clean it all up. Got to get north. Bigtime tornado massive hail. Reporter now that same storm is heading east. Its heading east and south. The same system is going to kind of stall out and become a stationary front, so you have severe forecasts not just for the state of nebraska, but also through iowa, southern minnesota and green bay. You even make it this evening during dinnertime into the damaging wind threat, robin. I know youre keeping an eye on that. Lets go back to george in houston getting ready for the big debate tomorrow night. George . Thank you, robin. Were going to start with the shakeup at the white house. President trump parting ways with his Third National security adviser in less than three years. John bolton is out after major splits with the president. Our National Correspondent terry moran is at the white house, and terry, the president insists he fired bolton. Bolton says he resigned. Reporter thats right, george, good morning. Its messy, thats for sure. It was sudden but not surprising. This was a long time coming. John bolton and President Trump have been disagreeing for months behind the scenes on the president s approaches, peace overtures to north korea, to iran, to afghanistan, and now as you say theyre going at it in public. They cant even agree on how it all ended. The white house this morning is scrambling to fill yet another big vacancy after President Trump abruptly announced he was getting rid of his Third National security adviser, john bolton. The president tweeting, i asked john for his resignation. But bolton saying thats not how it happened telling abc news, he never asked me to resign directly or indirectly. Bolton also tweeting, i offered to resign last night, and President Trump said, lets talk about it tomorrow. Boltons reputation as a hawk and advocate of using u. S. Military power around the world put him at odds with the president. John bolton is absolutely a hawk. If it was up to him he would take on the whole world at one time, okay . Reporter one recent flash point, trumps negotiations with the taliban in an effort to strike a peace deal in afghanistan. Did he leave the white house because he disagreed with you in particular over talks with the taliban . So last night, the president asked for ambassador boltons resignation. The president is entitled to the staff that he wants at any moment. Reporter trump ally senator Lindsey Graham says the next appointee must adapt to trumps style. I dont care if President Trump and kim jongun go on vacation. If thats what it takes to give up the nuclear weapons, im okay with personal diplomacy. Reporter as the president hunts for his fourth National Security adviser in three years, critics warn, instability has its price. These abrupt changeovers in his leadership team, while they might make for Great Television and they might work well on a tv show where your signature line is youre fired doesnt make for predictable or steady management. Reporter no president has ever had four National Security advisers. Thats a crucial position in three years. President trump says hell name that man or woman next week. In the meantime, secretary of state mike pompeo has managed to survive in Many Administration from the very beginning. Hes the dominant player on Foreign Policy here, george. Yeah, there doesnt appear to be any daylight between pompeo and the president. Meantime, terry, relief for President Trump overnight. His candidate in that special house election in North Carolina squeaked out a win. Reporter thats right. That is good news for President Trump, but it comes with a little bit of a warning sign too. Dan bishop, a state senator from North Carolina, hanging on to a seat republicans have held since 1962 that was gerrymandered for them to win, barely eking out a victory by just about two points. Republicans had won it by 12 over an iraq war veteran democrat. It is a win and a win is a win but it does spell trouble for republicans Going Forward if that is the way things are going to fall next year. George. Okay. Terry, thanks. Lets turn to our brandnew poll showing how the Top Democrats are doing against President Trump ahead of tomorrow nights debate. With the president s Approval Rating down to 38 approaching his record low, hes now trailing all the Top Democrats in headtohead matchups. Our senior White House Correspondent cecilia vega here with me with all the details. Good morning. Reporter good to be here. These numbers should really give the president and his team some pause ahead of this debate. If the election was held today, five democrats would handily beat him. Let me show you those numbers. Joe biden leading the pack by 16 points and not the only one with a doubledigit lead. Bernie sanders is there followed by Elizabeth Warren, Kamala Harris and Pete Buttigieg with a sixpoint lead. Really this is about concerns over the economy. Thats whats driving this among americans who think the recession who think a recession is likely. Biden leads trump, 7020. I thought it was interesting in the poll. In those states that trump won in 2016, a biden versus trump matchup is very tight. It should give the democrats some pause as theyre trying to win back the White Working Class voters that trump won last time. Far ahead in the blue states and talking about the economic concern, theres more concern about a possible recession Going Forward and the fact that the idea that President Trumps trade war with china may be fueling that. And that is why these approval numbers that you talked about at the top of this are stagnant for him right now at 38 . He still enjoys strong support among republicans but the takeaway in the poll, its still early. Americans are still making up their mind on all of these. It shows more than half the voters can change their mind. Thanks very much. All the top contenders here for tomorrow nights democratic debate sharing the same stage for the first time. That starts at 8 00 p. M. Eastern. Michael . Were looking forward to that, george, and were going to turn now to new developments in the battle against isis. A u. S. Led coalition dropping 80, 000 pounds of bombs on an island in iraq filled with members of the terror group. James longman is in london with all the details. Good morning, james. Reporter good morning, michael. Quite extraordinary images out of iraq. Take a look. U. S. Air force commanders released footage of 80,000 pounds of bombs that were dropped on an island described as infested by isis and it was recorded from the air. You can see those bombs spread across the whole area effectively carpet bombed. The u. S. most advanced warplanes taking part. Huge mushroom clouds visible and all this shows isis is very much a threat. Donald trump claimed victory over the group, but after losing control of the socalled caliphate, isis sleeper cells melted back into the population and have since launched deadly attacks. Over in syria, refugee camps are proving Fertile Ground for extremists. Chilen dancing around an isis flag and while those strikes can wipe out large groups of tajefighters its hard to beat the ideology with bombs alone, amy. James longman, thank you. Now to that spy mystery making headlines. Reports that a cia operative deep inside the kremlin was pulled from russia over fears his cover had be b well, now, moscow is responding and Martha Raddatz is in washington with all the latest on that. Good morning, martha. Reporter good morning, amy. Overnight an independent russian newspaper reporting that the man believed to be a highly placed spy for the u. S. Worked for five years as an assistant to one of Vladimir Putins top Foreign Policy aides. He was reportedly one of the cias most valuable russian spies working at this building in moscow with access to the highest levels of the kremlin, the heart of Vladimir Putins government. Cnn was the first to report that after decades of spying for the u. S. In late 2016, he found himself in grave danger. The spy was instrumental i concluding that russia had interfered in the 2016 election, and that putin himself had orchestrated the interference, but his identity was starting to leak. The russians now revealing the name of a former russian official who worked in the kremlin, but putins spokesman calling reports that he was a mole pulp fiction. They say he was fired. Secretary of state mike pompeo also taking issue with reports. The recording is materially inaccurate and you should know i dont talk about things like this very often. Reporter we have not confirmed the name of the spy nor will we repeat the name. The russians revealed it. The reports say the cia eventually extracted the spy, his wife and children who could remain in danger. It was just last year that russia was blamed for the attempted murder by poisoning with a nerve agent, a former russian intelligence officer, Sergei Skripal and he made it clear spying will not be tolerated in the past. There were multiple assassination attempts so the spy reportedly working with the u. S. Does remain in grave danger and he might live right here in the u. S. , a man with the same name as the official russia identified bought a house an hour outside of washington. It would be highly unusual for an extracted spy to use his real name, but former officials tell us, robin, that in the end, it is up to that person to decide, robin. All right, martha. Thank you. Now to that urgent new vaping warning from the American Lung association claiming ecigarettes can cause irreversible lung damage and disease saying people should just not use them. This comes as we learn another vapingrelated death. Adrienne bankert is in los angeles, has the latest for us on that. Good morning, adrienne. Reporter good morning to you, too, robin. These numbers just exploding within the past few months. The American Lung association is saying that young people are at greater risk with a disproportionate number of youth becoming gravely ill. Its a staggering outbreak with more than 14 vaping cases in texas alone. Health officials revealing a terrible trend. This morning, the American LungAssociation Says in a statement, ecigarettes are not safe and can cause irreversible lung damage and lung disease. The cdc investigating the rising number of more than 450 patients in 33 states suffering from serious lung illnesses as the nations death toll linked to vaping rises to 6. The latest, a patient in kansas, over 50 years old with Underlying Health problems whose symptoms worsened rapidly. What weve seen in the course of the past, lets say, month is an increased number of people coming in with respiratory problems as a result of vaping. Reporter Health Experts are still trying to determine a cause for such a violent and sudden response. The cdc says while many of the patients, but not all, reported recent use of thccontaining products, some reported both using thc and nicotine. We dont know but something clearly has changed the last month to six weeks in the products that are being vaped and thats what the cdc is working to find out. Reporter a Houston Area High School student is the third person in the last month to be rushed to the hospital for a medical emergency after they suddenly fell ill from vaping after a school event. A girl handed it to him, he hit it, passed out and would not wake up. Reporter that young man was treated and released from the hospital. For 17yearold Whitney Livingston in tyler, texas, she is spending her senior year in high school on a ventilator and her mom has a message to other parents. She told me she was smoking cigarettes and i thought it was safe to smoke Something Else, help them make the right choice because it can save their life. Reporter and medical experts stress that symptoms may mimic the flu or pneumonia. The cdc is looking to figure out if theres one common ingredient with vapes and ecigarettes that links all these recent cases. Guys. Still so many more questions than answers right now.
