The race for the white house and the first debate for the democrats looking to take an President Trump. Ten took the stage in miami last night. Ten more tonight. The economy, immigration and health care at the top of their agenda. Abcs mary bruce with all the highlights. Good morning, mary. Reporter good morning, george. Last nights showdown was a chance to talk on the national stage. They outlined their visions for what america is and should be and exposed deep divides on immigration and health care but the candidates rarely seemed to take on each other but focused on the one thing they agree on getting a democrat back in the white house. Ten candidates, two hours of debate, one big au they started in agreement. The candidates going after trumps economy. Senator Elizabeth Warren whos been rising in the polls pushed for what she called a structural change in government. Reporter new jersey senator cory booker said the economy is failing average americans. Its about time we have an economy that works for everybody. Reporter but it didnt take long to see clear contrasts. Who here would abolish their private Health Insurance in favor of a governmentrun plan . Just a show of hands to start out with. [ applause ] all right. There are a lot of politicians who say, oh, its just not possible. We just cant do it. Have a lot of political reasons for this. What theyre really telling you, they just wont fight for it. Reporter the debate over immigration leading to some breakout moments for candidates who have been flying under the radar like new york city mayor bill de blasio. For all the american citizens out there who feel youre falling behind and feel the American Dream is not working for you, the immigrants didnt do that to you. The big corporations did that to you. Reporter former san antonio mayor Julian Castro gave a passionate response to that gutwrenching photo from the border, a warn a father and his young daughter drowned at the border in search of a better life. Watching that image of oscar and his daughter, valeria, is heartbreaking. It should also piss us off and i would sign an executive order that would get rid of trumps zero tolerance policy, the remain in mexico policy and the metering policy. Reporter castro came ready for a border battle with beto orourke. Youre looking at just one small part. Im talking about a comprehensive rewrite of our immigration laws. Thats not true. Thats actually not true. Reporter he was the first of the night to speak in spanish. [ speaking a Foreign Language ] reporter but others followed suit.

I just want to say theres three women up here whorigh cho. Reporter ending where it began going after trump. The biggest threat to the security of the United States is donald trump. [ applause ] reporter now the one name that surprisingly did not come up at all last night the early frontrunner, joe biden. Not a single mention by name but that will all change tonight when joe biden Takes Center Stage along with Bernie Sanders and pete buttigieg. No question about that. That line from jay inslee about President Trump being a National Security threat, surprisingly not that much focus on the president directly last night. Reporter yeah, george, in many ways it was surprising that this debate wasnt really about donald trump. This was much more about the candidates themselves and their visions for the future of the democratic party. They spent much more time discussing policy differences than impeachment. For lesser known candidates it was also simply an introduction, a chance to tell voters where they stand, george. Mary bruce, i know youll be there again tonight. Lets bring in our chief white house correspondent, jon karl, in japan with the president , and jon, the president may not have been the focus last night. He was traveling but he was watching. It appears that the president s television aboard air force one was tuned in to the debate, george. About 35 minutes in, he tweeted a oneword take calling it boring. But, george, apparently he was still watching that boring debate a half an hour after that because he also tweeted an attack on the Technical Glitch the debate had affecting the audio for a short time. So, yes, he was watching. The president and republicans hoping to make a target of the democrats plans, particularly on the economy and health care. Absolutely. Particularly on the fact that virtually every democrat on that stage took positions to the left of barack obama, playing right into at least from the campaigns view their plan to portray the democrats as simply too far to the left effectively a socialist party now. Big weekend ahead for the president there in japan. Meetings with president xi of china and president putin of russia. Yes. Hes going to be meeting with putin tomorrow, george. This will be the first meeting between the president and putin since the release of the Mueller Report but perhaps the most consequential meeting this weekend will be with president xi of china, something the markets will be watching very carefully. World markets, whether or not they can come to some kind of agreement to avert or end what looks like an allout trade war. Jon karl with the president. Thanks very much, jon. Michael . As we saw the crisis at the border took center stage at last nights debate, our chief National Correspondent matt gutman gained access to one of the facilities in the middle of the firestorm and he joins us now from clint, texas. Good morning, matt. Reporter hey, good morning, michael. This facility is a hub for uncompanied migrant children. Its now the target of a restraining order filed just overnight alleging that conditions inside are unsafe and unsanitary. Now, when we saw it there was soap, there were tooth brushes, but its basically like a jail situation. Its jarring to see toddlers walking inside cells, kids the same age as the little girl in that picture. This morning we learned another family, a woman, a toddler and two infants were found dead on the u. S. Side of the border just off the rio grande. Migrants have long hoped the rio grande would carry them into the u. S. , but this mexican psa released tuesday warning the rivers currents could also kill them. [ speaking a Foreign Language ] the warnings follow this haunting image, Oscar Ramirez and his daughter valeria tucked into his shirt. Her arm draped over his neck, drowned on the banks of the rio gran grande. Valeria was just shy of her second birthday and her grandmother clinging to the toddlers stuffed animal. This is her favorite doll, she says. The image graphically capturing the desperation of migrants who risk everything to cross into the u. S. And used as a political bludgeon on capitol hill. The president s actions at the border are a whirlwind of incompetence leading to pictures like this. Reporter President Trump blaming the tragedy on democrats and what he called open borders. Open borders mean crime and open borders mean people drowning in the rivers. Reporter but scrutiny is also mounting on the governments handling of childrens detention centers. Overnight, a restraining order filed against two texas facilities demanding immediate remedy for the Public Health emergency at the facilities. Abc news got a chance to see one of the two facilities in the restraining order. But no cameras allowed. Any chance to take the cameras inside to show people whats going on . No, its a pen and pad tour. We were also forbidden from speaking to any of those children. This facility was designed to accommodate about 100 people for 8 to 12 hours, but it has had up to 700 children inside, and their average stay right now is six to ten days. A situation that even the Border Patrol admits it just cant cope with. Amy . Matt gutman at the border for us, thank you. New trouble for boeing. Another potential problem discovered on its 737 max jet, the passenger plane already grounded following those two deadly crashes. Senior transportation correspondent david kerley is at Reagan National airport with the latest on this one. Good morning, david. Reporter good morning, amy. This is a new, separate problem which could keep the max on the ground even longer. During a test flight on friday an faa pilot found some of the controls, a button on the control, it took longer to nose up the plane and bring it to level than he expected. Now, this is not related to the socalled mcas system which we saw related to those two deadly crashes. This is a separate part of the problem. Boeing believes they can fix wit a software fix. The faa is wondering whether the computer chip in all those maxes would have to be replaced and that could take a whole lot longer. The airlines pushing out their cancellations, now until labor day, through august, all the way to labor day. So the max not expected to fly for those three airlines during the very busy Summer Travel season. George . Complicates the summer. Okay, david, thanks very much. New developments involving that missing utah student who disappeared after leaving the airport in a lyft, was dropped off at a park. This morning authorities have zeroed in on a home, and abcs gio benitez has the latest. Reporter this morning, new developments in the search for missing university of utah student mackenzie lueck. Police descending on this Salt Lake City house early in the afternoon with a search warrant. Neighbors saying the police had been there for much of the day. The leads developed that we developed led us here. Then we served the search warrant. Reporter this comes as the search for lueck enters its tenth agonizing day. Police say lueck was last seen in these newly released images. The 23yearold then texted her mother before ordering a ride share to this north Salt Lake City park where police say she met someone at 3 00 a. M. That ride share driver has been cleared as a suspect. Police are now looking at luecks digital footprint for clues. Does mackenzie have an alternate phone she has used in the past or is using . Does she have social media accounts we dont know about . Reporter investigators say there is no evidence of foul play, but with few leads and no contact, they are leaving no stone unturned. We are treating this with a high degree of care and caution. Reporter and police still havent said if they know anything about who lueck met at that park. Thats the mystery right now and to make matters even worse they found that the surveillance cameras at that park were what they call dummy cameras. So they dont actually work so theyre really relying on witnesses to come forward. Wow, all right. Thank you so much, gio. And now to the latest on that 2yearold who was hit in hat one wentizing ofned ne u g medical condition of that 2yearold girl struck in the head by a foul ball a month ago at houstons minute maid park. M lawyer and saying the young girl was hospitalized for several days with a Skull Fracture and associated subdural bleeding, brain contusions, even suffering a seizure at the hospital and the familys Attorney Says she will be reassessed again in a few weeks and they will know more, but particularly with a young child it will take sometime to know just what the future holds. Reporter that foul ball coming off the bat of Albert Almora jr. Of the chicago cubs. Yeah, im speechless. Im in im at a loss of words. Reporter according to the family lawyer, the little girl and her family were sitting just ten feet outside of that protective netting which is meant to stop foul balls from injuring fans. The onetwo comes home and bellinger rifles it foul. Reporter days ago another fan was struck by a foul ball in los angeles. That fan was treated for her injuries at the hospital and has recovered. Last year Major League Baseball introduced a mandatory policy for teams to have netting that reaches to the end of both dugouts to protect fans. But these incidents have some asking if the netting reaches far enough. The attorney of this little girl tells us the family wants that netting extended as far as the foul poles in the outfield and it is up to each stadium and team to determine the netting to be on that dugout. Three of the 30, the white sox, nationals and dodgers, are extending it. This puts a lot of pressure on the astros to do the same. We are pulling for this girl who remains on medication. Thank you so much. We absolutely are. As the u. S. Womens soccer team prepares to face off against france tomorrow they are also facing a war of words between their cocaptain and the president of the United States. Abcs will reeve is here with more. Good morning, will. Reporter good morning, amy. This morning as team usa gets ready for its biggest match of this world cup, one of the teams captains taking on an even bigger opponent, the president. Rapinoe, shot, goal. U. S. Wins. Reporter soccer superstar Megan Rapinoe has been steamrolling opponents during the world cup, but should the u. S.

Im not going to the [muted] white house. No. Im not going to the white house. Were not going to be invited. Reporter rapinoe who is openly gay described herself as a walking protest when it comes to the Trump Administration. But her latest comment quickly got the president s attention. I am a big fan of the American Team and womens soccer but megan should win first before she talks. Finish the job. We havent yet invited megan or the team but i am now inviting the team win or lose. Rapinoe scores. Reporter rapinoe has long been an outspoken against ineqlitynd pr others neiling the kneeling during the National Anthem in the past. When the rules were rewritten rapinoe respected the rule opting not to sing it with her hands behind the back at this world cup. President trump also taking aim at the 33yearolds anthem protest, megan should never disrespect our country, the white house or our flag, especially since so much has been done for her and the team. Rapinoes teammates coming to their cocaptains defense. Defender ali krieger tweeting in regards to the president s tweet today, i know women who you cannot control or grope anger you, but i stand by mpinoe and will sit this one out as well. U. S. Soccer is not commenting on the matter but social media is buzzing with people taking some supporting rapinoe and her teammates. Others saying her comments have made them decide to root for france. Wow. Yeah. That match is tomorrow and its the biggest one in the world. Big opponents and also the heat wave happening in paris. Match at 9 00 p. M. Local time.
