"i feel very bad because i can

see my friends going to school, ziki told us, and i am struggling." when you go to sleep at night, before you go to sleep, what do you think about? "school," he told us, his only dream. well, sometimes dreams do come true. now ziki is getting ready for school for the very first time. around 50 cbs viewers were so moved by ziki's plight, they connected with sister katherine who has saved over a thousand children from the mines. enough money was raised to send ziki and his three siblings to school. "i would see the other kids going to school and i would look at them," ziki said. "but today, feel the happiness they feel and i'm now like them." there was some first day nerves. he held back tears outside the classroom, but it wasn't long before ziki bravely stood up and introduced himself to his new classmates.

and joined the soccer team. ziki has changed the lives of these children and maybe more. "if i become a government minister," he said, "i would ask all the children who work in the mines to go to school so they could become like me." deborah petta, cbs news, democratic republic of congo. >> that is overnight for this friday. for some of you, the news continues. for others, check back for the morning news and cbs news this morning. from the broadcast center in new york city, i'm jeff glor.

this is the "cbs overnight news." >> welcome to the overnight news. i'm vladimir duthier. national guard troops are waiting for marching orders to help guard the southern border from illegal immigrants and drug smugglers. but the mission is still unclear. president trump ordered the deployment wednesday, saying a drastic surge of illegal activity left him no choice. yesterday secretary of homeland security kirstjen nielsen said the amount of troops is still being decided. the pentagon could not say if any of the troops would be armed. while mr. trump's move is stirring controversy, he is not the first president to send in the guards to help with border security. here is chip reid. >> the threat is real. >> reporter: homeland security secretary kirstjen nielsen said

national guardsmen will be sent to the border soon. >> department of defense and department of homeland security work together with our governors to deploy the national guard to our southwest border to assist the border patrol. >> reporter: but she could not say how big the force would be, when they would be deemployed or for how long. >> it will be strong. it will be as many as needed to fill the gaps we have today is what i can tell you. >> reporter: in a memo the president told the situation on the u.s. border a point of crisis and continues the lawlessness that continues at our southern border is fundamentally incompatible with the safety, security and sovereignty of the american people. the congressional hispanic caucus fired back, calling the president's actions unwarranted, and saying they will ultimately undermine our military readiness. federal law prohibits the u.s. military from acting as law enforcement. they cannot arrest illegal border crosser, and can only act in a support capacity. nielsen said the effort would be similar to a 2006 operation when president george w. bush sent 6,000 troops to assist border patrol.

in 2010, president obama also sent national guard members to the southern border. senior administration officials said illegal crossings were at a, quote, staggering high in march, but did not offer specific figures. >> the urgency cannot, however, be underscored. it's time to act. >> reporter: it's not clear exactly how many people crossed the border illegally last month, but customs and border protection says that apprehensions rose by 200% this march compared to march of 2017. however, for the year, apprehensions are down compared to the same point last year. >> president trump's escalating trade standoff with china could hit many of his voters the hardest. this week china announced tariffs on pork, beef, and soybeans. those industries are the lifeblood of rural communities in republican-leaning states. dean reynolds went to a pig farm in tippett on the, indiana to see one of the front lines in a possible trade war. >> reporter: last year the u.s. ex-ported some $1.1 billion of

pork to china. and the pork industry supports about 550,000 jobs in mostly rural america, which overwhelmingly supported donald trump. >> i don't think there is any segment of our industry that will escape some financial hard times if we do indeed see a diminished export market. >> reporter: keith shutmer is a pig farmer and trump supporter. the thought of a possible 25% chinese tariff on american pork makes him nervous. >> if you had the president right here, what would you tell >> we would just reiterate how vitally important the exports are to our industry. >> reporter: china's tariffs would impact nearly 10% of all u.s. pork exports. of the top 10 pork producing states in the u.s., eight of them voted for president trump in 2016. are you reconsidering your support for him? >> we have to have a trust that he has our best interests in mind. and we just have to believe that

there is more to these negotiations than we understand. >> reporter: china's proposed 25% tariff on american soybeans could have an even bigger financial impact on u.s. farmers. the american soybean association says china buys nearly a third of u.s. production annually. that includes about a quarter of all the soybeans grown in illinois. >> i'm not as enthusiastic a supporter as i was two years ago. >> reporter: trump supporter eldon gould is one of illinois's over 43,000 soybean farmers. >> well, i guess i would have to say that i'm disappointed. and i'll be the first to admit that i voted for mr. trump. but i was hoping that he would take a more reasonable approach to trade. >> reporter: now yesterday, the white house economic adviser, larry kudlow, suggested that all this talk about tariffs may just be a negotiating ploy. and the white house in fact said the door is open for further

talks with beijing, and that no firm date has been set for the imposition of u.s. tariffs against china. >> facebook ceo mark zuckerberg is getting ready to testify before congress next week. lawmakers want answers about the company's data privacy scandal that is now even worse than first thought. here is nancy cordes. >> reporter: they want to know whether any other companies have been able to get access to this kind of data, and exactly what kind of information we're talking about. zuckerberg insists that facebook has gotten a lot better at protecting user information. but he also admitted that every facebook user, and therer two billion of them, should assume that at some point their personal information has been scraped from the site by a third party. >> it's clear now that we didn't do enough. >> reporter: in a rare conference call with reporter, zuckerberg fell on his sword, acknowledging that a company hired by the trump campaign was able to access the personal data of far more users than

previously believed, up to 87 million people unwittingly shared their information with cambridge analytica, a political consulting firm partially funded by the billionaire mercer family. >> when you're building something like facebook, there are going to be things that you mess up. and if we had gotten this right, we would have messed something else up. >> reporter: but some lawmakers see this as the latest in a series of security blunders that zuckerberg should answer for in person. >> the air needs to be cleared by the ceo. >> reporter: they want to know why zuckerberg initially laughed off the notion of foreign meddling back in 2016. >> the idea that fake news on facebook influenced the election in any way i think is a pretty crazy idea. >> reporter: that he says was a mistake that has since been fixed. just this week, facebook removed more than 270 russian pages and accounts, and restricted apps from accessing certain details about you and your friends. still, facebook's stock price

has tumbled more than 10% since last month. morgan stanley warning that data privacy issues are feeding investor concern. how can you ever fully reassure users that their information isn't going to be used in a way that they don't expect? >> we can certainly do a better job of explaining what we actually do. the vast majority of the data that facebook knows about because you chose to share it. >> reporter: zuckerberg was asked whether anyone at facebook has been fired over this cambridge analytica scandal, and he said no. he has said, however, that social media companies like facebook perhaps should be regulated more heavily by the federal government. >> the "cbs overnight news" will be right back.

this is the "cbs overnight news." >> an old recall is coming back to haunt toyota. the automaker voluntarily recalled hundreds of thousands of prius hybrids in 2014 and 2015 because some cars would lose power while being driven. toyota says it fixed the problem, but now a california dealership is refusing to sell certain models and filed a lawsuit saying toyota's solution is still a safety risk. here is kris van cleave. >> reporter: these voluntary recall dealt with a component known as the inverter in the engine. several years later car dealer roger hogan says he sees a steady stream of these hybrids coming boo his dealerships with an issue he believes the recall should have fixed.

>> the experience was terrifying. >> reporter: kathleen ryan says she was in the fast lane on this busy los angeles freeway in january when something went wrong in her 2010 toyota prius hybrid. >> it felt like someone pulled the emergency brake. i mean, i couldn't believe what was happening. you step on the accelerator and nothing happened. >> reporter: a toyota mechanic traced the problem to the car's inverter, which controls the transfer of electricity between the battery and the prius' two electric motors. in 2014, ryan's prius was among roughly 800,000 voluntarily recalled because circuit in the inverter could overheat and fail potentially causing the vehicle to lose propulsion. documents she got the software fix offered by toyota that added a fail-safe mode intended to keep the karung at a reduced speed long enough for a driver to safely get off the road. you won't sell any of these cars? >> these are no sale. these are locked up, keys pulled, in the computer, do not sell these cars. >> reporter: roger hogan owns

two southern california toyota dealerships. he says after seeing more than 100 of the sedans come in with failed inverters that had previously received the recall fix, he stopped selling many used priuses, which were among his best-seller. >> a recall is supposed to prevent the incident from happening. it's not supposed to be you fix it after you've experienced a horrific event. you're supposed to prevent that event from ever occurring. why should you be allowed to put someone's life in danger? >> reporter: do you feel like toyota is putting people's lives in danger? >> absolutely. >> reporter: hogan will still take priuses as trade-ins, but if it's a 2010 to 2015, they're going to end up here on the roof. there are about 50 of them parked. he estimates having a million dollars parked in priuses he will not sell. in the 40 years you've been in the car business, how often have you unilaterally done a stop sale on a type of car? >> i've never done anything like this. i've never felt i had the need to do anything like this. >> reporter: in october, a

toyota vice president wrote to hogan, when implemented, the software change lessens the likelihood of failure. and once in fail-safe mode, the vehicle can be safely driven for some time. but in december, hogan petitioned federal regulators to investigate the recall fix for not addressing the inverter failures directly, writing there are lives needlessly at risk. >> something caused these holes. >> reporter: metal holes inside this inverter hogan showed us melted and something pierced it. it came out of martha's 2012 prius. the engine component got the recall repair prior to failing late last year on this busy road with a 50 miles an hour speed limit. >> it slowed down to the point that i was barely going. and fortunately, there wasn't a lot of traffic on there. i'm thankful that i wasn't on the freeway. >> reporter: if you hit the gas, did significant happen? >> no. no, it didn't. >> reporter: hogan is also suing toyota for $100 million. his suit alleges breach of contract and fraud, arguing the automaker's remedy did not fix

the safety defect. according to the complaint, the software fix costs about $80 a car. to replace the inverter can cost up to three grand each. the company changed the inverter design in late 2014. hogan's suit also claims toyota is trying to block him from handing over his dealerships to his sons. but toyota says there is not a safety issue, and hogan's claims are without merit. the company has confidence its remedy is effective, and the recall's addition of a fail-safe mode was implemented to enhance vehicle safety. instead, toyota argues the timing of the lawsuit and hogan's claims are motivated primarily by a separate dispute he has with toyota over management and succession issues involving his dealership, not the effectiveness of the prius inverter recall. there are going to be people who see this and say this is about promoting a lawsuit, that you have a grudge against toyota, that it's not -- this isn't really about the prius. >> my real grudge with toyota has always been their lack of commitment to customer safety.

that's what started this problem. i didn't create the 100 failures at my two stores. i didn't manufacturer those cars and then issue a recall that doesn't work. toyota did. >> reporter: ryan is still driving her prius, but now with a new inverter. >> i really appreciate the opportunity to share this story, because people who have these priuses who have had them recalled and assume that everything is okay, this could happen to them. >> reporter: the national hay highway traffic safety administration tells cbs this morning it is monitoring its complaints and will take action as needed. toyota insists that the vehicles are safe and says it too is monitoring the issue. >> the "cbs overnight news" will be right back. many sleep-aids have pain medicine but zzzquil is different because why would you take a pain medicine when all you want is good sleep? zzzquil: a non-habit forming sleep-aid that's not for pain, just for sleep.

"ready player one" is my first published work. >> reporter: in a literary

magazine? >> nothing. >> reporter: short story? you were just going out, giving it a try. "ready player one" envisions a dark future in which people spend most of their time plugged in to a virtual online world. the plot involves a high stakes scavenger hunt. the clues come from 1980s pop culture. >> this is great. >> reporter: promotion of the film has taken over the real world. >> so much stuff in here i want to steal. >> reporter: including a massive interactive exhibit in cline's hometown of austin, texas. so these are the stacked trailers from the book? >> well, i grew up in a trailer park, and living in a trailer park feels not great. anso i imagine like in the future what would be worse than a trailer park? >> reporter: cline and his brother eric were raised in rural ohio by a mix of their grandparents and an atari console. a love for "star wars" fed dreams of working in the movies, but for years the closest ernie came was a job as a video store

clerk. when writing screenplays didn't quite work out, he started a novel. nine years later with a baby daughter to support, cline sent the book to publisher. >> and the very next day we had sold the rights to "ready player one" for more money than i ever imagined i would make or anyone in my family had ever made. my whole life had just changed in that first 24 hours. and they said oh, by the way, now there is a bidding war going on in hollywood for the film rights. >> reporter: why did you think it would make a good movie? >> because it was great adventure. i wanted to make a movie because i hadn't made an adventure film like this, my god, for decades. >> reporter: when steven spielberg signed on to direct, cline, the ultimate fan boy, became his collaborator. ⌞> so he is an authority on popular culture. when we made the movie we kept going back to ernie just to pick his brain. >> reporter: was he able to play it cool around you? >> yeah. i think he was hanging on a little bit. >> even now just talking to him, i'll hang up the phone having a conversation with him. i just talked to steven

spielberg. it never goes away because he was such a giant figure in my childhood. >> reporter: you have steven spielberg's number in your phone? >> no, he calls me. i could get ahold of him if i needed to, but he doesn't hand it that number. >> reporter: success has given ernie bigger turkey, now he is an action figure. >> reporter: but it's love for the little ones that got him here. to make the point, he brought out the atari console he got for christmas in 1978 and started playing a game called adventure. >> it was the first virtual reality game that i ever played. >> very virtual. >> reporter: in the flashing fuzzy picks excels, young ernie found a secret room where the designer had hidden his name. >> that was just a profound moment. >> reporter: years later, that moment gave cline the idea for a virtual staph injury hunt, the plot of "ready player one." >> are you willing to fight? >> reporter: it's a story about someone trying to use their love and knowledge of '80s pop

culture to achieve fame and fortune. and you're the person who did that. >> i know. i feel like i am a testament to what happens if you be free what you love and why you love it and not afraid or worried about what other people will think about your love or your passions. just be bold and celebrate the things that you're passionate about. and amazing things can happen.

building a home in the united states takes about three to six months. the average cost is near lay quarter million. but now 3-d printing technology is being used to drastically speed up home construction for a fraction of the price. omar villafranca shows us how. >> this isn't a technology that is going to help a little niche of the way we think about shelter. this is a paradigm shift in the way we build houses. >> yeah. >> reporter: this technology starts with a one-ton 3-d printer which squeezed out enough concrete to build a small two bedroom, one bathroom single-family home. jason ballard is co-founder of ikon, one of the companies behind the project. >> this house right here was printed in 47 hours at quarter speed. at full spaed it could have printed this house in 11 or 12

hours. >> reporter: a home in 11 or 12 hours. >> and that's on version one of the technology. >> and it's designed to take families that have been living in tents or shacks and to bring them into what we believe is a beautiful home that they can build their lives on for the >> reporter: brett hagler runs the nonprofit new story. he is hoping to bring this technology to poor technologies in el salvador by the end of next year. when you see a home like that, do you get excited about the future? >> i do, i do. i'm excited about everything concrete. >> you're going to add your cement. >> reporter: university of texas engineering professor is an adviser on the project. while sees the potential for 3-d printed homes, she questions how the concrete mix will stand up over time. is there enough data out there saying that these kind of homes can be safe? >> no, there is not there. is not. >> reporter: does the building of these homes need the wait until there is data, or do the homes need to be built and then study the data? >> you have to do both at the same time.

if you wait until there is data to build it, you're never going to build it. >> reporter: icon will use this model home as an office for the next few years, while third party labs test its long-term durability. >> we're going make ourselves the guinea pigs before we put another family's life in the mix. >> reporter: and this particular design has limitations. utilities like electric and plumbing still need to be installed outside the walls. >> right now it's just going to be a novelty. it's just going to be eye candy. >> reporter: even if all goes as planned, it will likely be years before 3-d printing becomes a mainstay of u.s. residential construction. omar villafranca, austin, texas. that is the overnight news for this friday. for some of you, the news continues. for others, check back a little later for the morning news and cbs this morning. from the broadcast center in new york city, i'm vladimir duthier.
