for democracy, that is why i came forward, and let's be clear it doesn't have to be this way. we are here today because of deliberate choices facebook has made. haugen also accuses instagram, owned by facebook, of failing to crack down on accounts that are damaging to teens' mental health. and a new cnn analysis found proof of the app promoting extreme dieting, and eating disorders to young girls. we're going to have much more on that in a moment. let's get to cnn correspondent donie o'sullivan. you've been covering this a long time. let's begin with something that happened in the background yesterday, that facebook, instagram, whatsapp, they all went down, they're back up this morning, they all went down after really unusual widespread outages. the timing uncanny to say the least, do we have any reason to believe this was deliberate? do we know who is responsible? >> reporter: so, jim, at the moment, we don't know. facebook put out a statement late last night essential saying it was a glitch, a technical air and facebook's computers, they're data centers stopped talking to each other and the reason why it took so long to get back online is this glitch actually affected the internal systems as well. we have sought some clarity from facebook in terms of if they're investigating, say, it was maybe a rogue employee given the timing of this, but we haven't heard back yet. certainly at the moment, there is -- they are not saying it is an attack or anything nefarious of that kind. they appear to be suggesting it is a glitch and also they are importantly pointing out that no user data was compromised. but just final point on yesterday's outage, a lot of what we're going to hear on capitol hill today is facebook's power, and i think yesterday was a great reminder of that. facebook, one company, controls three of the world's biggest platforms. facebook, instagram and whatsapp. and when there is a problem with one, there is a problem with all of them. >> that's for sure. that power too i think is what so many people have latched on to, especially as we heard from the whistle-blower on sunday. we have obtained a copy of her opening statement. what more are we expecting to hear from her this morning? >> this is going to be pretty powerful testimony today. i think take a look at part of her opening statement here where she says she believes she did the right thing and necessary for the common good, but she knows facebook has infinite resources, which it could use to destroy me. i came forward because i recognized a frightening truce, almost no one outside of facebook knows what happens inside facebook. we're going to learn a lot more about that today when it comes to childhood harms, facebook's handling of elections and the democratic process, and it is all going to unfold in the coming hours. >> so, senator richard blumenthal, handling the hearing today, his office carried out what is a pretty remarkable but also concerning experiment. set up a facebook account, claiming to be a 13-year-old girl, and then bombarded with content promoting self-harm, eating disorders. you did something similar. tell us what you found. >> yeah, we spent a lot of time this weekend speaking to blumenthal's staff. did a very, very simple experiment, but so powerful and so effective in really showing the issue here. set up an account, as a 13-year-old -- as a young teenager, 13-year-old girl, followed a few accounts about dieting, a few eating disorders accounts and almost immediately instagram's algorithm kept pushing, kept suggesting more and more and more pro eating disordering accounts, accounts glorifying the disorders. when cnn took some of these accounts to instagram, they took them down. they said, these accounts actually break our policies on promoting self-harm and eating disorders. but, again, not only were -- not only did instagram not catch these accounts, they were actively pushing them and promoting them to this young user. i wanted to play this one piece of sound if we have time from an interview on "new day" this morning with a father of a person who suffered because of this. have a listen. >> what we discovered after her death was that she had been seeing material on various platforms, but instagram was one of them, that promoted just being miserable. first of all, she would have seen material that made her feel miserable and hopeless and encourage that sort of depression and anxiety. and then even more worryingly she saw material that suggested suicide might be the only way out. >> and that is unfortunately too relatable to too many families across america and around the world. problems, mental health and social media. guys? >> yeah, absolutely, donie, thank you. i want to bring in laura edle son, researcher on misinformation, co-director of the cybersecurity for democracy in new york university. and in august, facebook shut down laura's account, the company said because of her research. there was some back and forth on that. laura said it was because research, but facebook denied that. i want to pick up where donie left off. it is so disturbing. it is hard enough for young girls and in many cases for young boys to not feel inadequate, to feel everything they're doing is wrong and doesn't measure up. when you have a platform that is directing them to sites that in the words of this father promoted being miserable, that showed that maybe suicide was the only way out, his daughter took her own life, to say that's damning is an understatement and yet as we learn from the whistle-blower a lot of this was known inside the company she claims, but nothing was done about it. does that match up with what you found? >> unfortunately yes. i think one of the most horrible things that all of this is that what i'm finding is the company's own internal research is consistent with what i and other researchers have been telling them for years is the case. that harmful problematic content is spreading rampantly on their systems. and they don't seem to be willing to do anything about it because doing something about it would cut into their profits. >> yeah, that's a part of the story that needs to be highlighted. this is facebook's own findings, right? on this threat. and they made a deliberate effort to hide those findings, which led haugen to come forward with it. facebook's response will be, listen, it is not -- i heard this multiple times from facebook executives, it is not in our interest for folks to have negative experiences online. their bottom line is only served by positive experiences. is that true? >> you know, that would have been a lot easier to believe three weeks ago before all this internal research came out. now we're finding that's just not the case. one thing i found the most damning about reading this internal research is that their internal researchers experimented with mitigations, things to reduce this harm. but doing, you know, enabling those mitigations would have cut into the company's bottom line. so they chose not to do it. i think that's, you know, one of the things i find unconscionable. >> they have the information, they're not acting on it. in her opening statement, we know haugen is going to say that google, pinterest, yelp, she found deliberate choices made by facebook. she says something more needs to be done. these are not tweaks to privacy laws, but actual regulation. i'm curious, from your point of view, based on your research, what do you see in terms of changes that would actually be effective at facebook? >> yeah. so we are calling for comprehensive federal regulation. and i think as a first step so much more transparency is needed because at this point how can the public have any confidence in anything that facebook says. so we just need a lot more transparency of public content to researchers. we probably need a mechanism for user safety audits so that, again, the public can begin to rebuild some trust. but i think the single most important thing is we need some kind of federal regulation to block facebook from putting its own profits ahead of user safety. that's what has to stop. >> listen, it is a rare bipartisan issue, democratic and republican lawmakers taking aim here, the question is can that work its way through the current legislative stalemates on capitol hill, something like that. laura, thank you for the work you're doing. >> thanks. well, the troubling headlines just part of a brutal monday for facebook. the company's stock plunged after the news from the whistle-blower founder mark zuckerberg lost billions in the sell-off, he has many billions more. >> there is that. cnn's chief business correspondent christine romans joining us now. really a rough day for facebook overall. how is the company's financial health right now? >> look, you know, profit doubled in the second quarter, you are using its site and its services for free and you're the product that it sells, right? so our social networks are incredibly lucrative for facebook. the stock down about 5% yesterday. that's a big move, yes. but this year it is still up 19% since it went public in 2012. up almost 800%. so the numbers show us that while we're questioning the democratic values that could be eroded, the personal safety of young people, whether algorithms are tweaked to foment descent, that conflict makes money for facebook, all these things we're talking about recently, all of that has been very profitable for this company. there is a new phase we're entering here, for many years there were those who said keep your hands off big tech, washington doesn't know how to regulate big tech. i think the new mood is not will you regulate facebook, but how will you regulate facebook? as for mark zuckerberg yesterday, bad day for him, he lost $6 billion on the day. that's a lot of money and that was enough for him to fall down in the rankings of a bloomberg billionaires index. he's number five now behind bill gates. you can see. he lost $6 billion, but $121 billion. he's been a very, very rich man, making money off of us, the product. we are the product. never forget it. >> not exactly a financial tragedy there. still $121 billion. christine romans, thanks very much. coming up next, former vice president mike pence suggests it is the media that is blowing the january 6th capitol insurrection out of proportion. even though that same crowd of rioters chanted they wanted to hang him. i'll be joined by republican member of the house committee investigating the insurrection as more subpoena deadlines draw near. also new this morning, astrazeneca just asked the fda for emergency use authorization for a new antibody treatment to fight covid-19, and brian laundrie's sister speaking to reporters. what she's sharing about the last time she spoke with her parents and what she says happened at the campground her family visited. at vanguard, you're more than just an investor, you're an owner with access to financial advice, totools and a personalized pln that helps you build a future for those you love. vanguard. become an owner. this is the new world of work. each day looks different than the last. but whatever work becomes... the servicenow platform will makit just, flow. whher it's finding ways to help you serve your customers, orchestrating a safe return to the office... wait. an office?

>> oh, jim, that coup attempt insurrection, that was nine months ago, we should just move on. no, look, we're going to do everything in our power to get him to testify. i mean, there is civil, there is criminal referrals that can happen if they refuse, refusing a subpoena from congress is a crime. and want to be clear about something, i mean, we have a right to get to the bottom of this. we aren't out to try to hang this around anybody's neck. we want answers. the problem is when you start seeing people resist, and people obfuscate, you have to look at that and geeo why are they doin that if they have nothing to hide? we have a lot of people coming and talking to us voluntarily. we'll get to the bottom of it. we want to do it quickly, efficiently and thoroughly. regardless of whether, you know, more or our generation gets the truth, we will, our kids' generations deserve to read an accurate account in their reference books. >> i just wonder, that is not an outlier position in the current republican party, and your view has revisionism on january 6th, these short nine months later taking over the gop. >> yeah. happened -- it didn't even happen nine months later. couple of weeks later, kevin mccarthy went and kissed the ring at mar-a-lago and literally -- figuratively literally took the paddles from the ambulance, put them on donald trump and resurrected him politically with that one single visit. and then all of a sudden it became maybe it was antifa. that night matt gaetz said we know it is antifa. it is like, what? that all started. you have the vice president, here is the thing so disappointing to traditional republicans like me is mike pence, i disagree we was complacent during the four years of trump, but he had a heroic moment. if you read the coup memo, that outlined a coup, that's literally what it did, that's what donald trump was pushing, mike pence resisted that, he could have gone with it, created a constitutional crisis, he's not going to win back the trump people. he's not going to convince us he was anti-trump. he could stand up and say i was with the president, until i wasn't and i don't understand this pivot. >> on pence, we have learned more on january 6th, including he made a call to former vice president dan quayle to seek his counsel on perhaps whether he had some power to overturn in that crucial moment. i wonder is the narrative of mike pence the hero that day, are we learning there is less to it? >> yeah, i'm not sure. so, you know, i don't know if he had called dan quayle to see can i do this or how do i resist doing this? i read the account in the book. the reality is he did his constitutional duty, so i don't think that's heroic. i think having stood in the pressure of donald trump is somewhat heroic in these days, unfortunately. i think the big thing for him to give him credit for on that day is the recognition that he could have done something different and thrown us into a complete constitutional crisis. what i don't understand is his life was in danger, the number three in line for the presidency was in danger and four, all within striking distance of a mob that killed a police officer, beat one to within an inch of his life, so do it to a politician, and now all of a sudden he's revising that day and saying he and trump are buddies again. i don't get this toxic hold the trump has over people, he never had it over me. maybe i just missed out. i'm glad i did. >> washington post reports that trump considered announcing his candidacy for 2024 after the afghan withdraw. he was convinced not to, but some believe he was close to doing just that. it is possible he could win. it is possible. do you believe a -- the u.s. democratic system as we know it would survive? not just the run, but a second trump presidency? >> i think our system is broken. and i'm not -- you know sitting here to say democracy is bad, the republicans are bad. i think what failed us is the two-party system that has kowtowed to the extremes. we have our freedom club in our party. now you have no offense the progressive caucus on the left that is looking a gift horse in the mouth with a bipartisan infrastructure bill, and doing what i saw the freedom club do five years ago, by the way. and the vast majority of americans in the middle aren't on twitter yelling. they're saying i feel so disaffected right now. and we're plugged into this matrix that says if you don't like joe biden's presidency, i don't like his policies, by the way, your alternative is it must be donald trump. oh, hell no. there is a vast array of options outside of those two, particularly outside of donald trump, but we're plugged into this belief that you only have one option. we got to break that belief and change things. donald trump very well may run again in 2024. i would have thought six months ago wouldn't, i think he sees joe biden stumbling, thinks he can win and he may win. >> just briefly, you mentioned the bipartisan infrastructure plan, you publicly supported that. given last week's failure to get it through, you know, infighting in the democratic party, do you still support the bipartisan infrastructure plan, will you vote for it? >> yeah, i'll vote for it. we're -- it is dangerous if they somehow tie the two together with the $5 trillion that mr. clyburn was saying i don't care how much it is, kind of to paraphrase him, that's a problem. i intend to vote for it. we need bipartisan infrastructure in this country. let's take the win. that's how we used to legislate, take the win and the controversial stuff you fight hard to get through. >> we'll see. we'll see if they meet this next deadline. adam kinzinger, thank you for joining us. >> anytime, jim. up next, cnn learned that johnson & johnson asked the fda to authorize booster shots for its coronavirus vaccine. plus, we're just moments away from the opening bell on wall street. looks like a slight bounce, trying to reclaim losses from yesterday, inflation and debt ceiling concerns still top of mind for investors and behind the big chunk of the recent declines, losses for some of the biggest tech firms. facebook stock a little higher after having its worst day of the year. ththis is how you become the best!

do you see any reason that it would not be granted, that emergency use authorization for a booster? >> no, i think it will be, erica. i think really the data, it suggests that, you know, one dose may not be sufficient. in fact, this could have easily been a two-dose vaccine. and the reality is the question then is it a booster? are we completing a series? it is unfortunate because it is nice to have a one-dose vaccine against the disease, but it may be we were asking for too much. >> i want to look at new data here that relates specifically to the pfizer vaccine, which is, of course, the one that most -- the vast majority of americans have been vaccinated have gotten. it shows two things. good and bad. hospitalization after five, six months remains the protection, i should say, against hospitalization remains very strong. but the protection against infection wains over time to 47% six months after the second dose. for folks at home, who may have been vaccinated like myself with pfizer, should they look at the numbers with concern or focus on the hospitalization number there? >> jim, i really think we need to focus on the hospitalization number. we have to remember this vaccine is really not designed and never intended to prevent infection. it is hard to get vaccines to be, you know t, that effective. so i think preventing severe disease, preventing hospitalizations and death is the outcome we need to expect from the vaccines. if we bring transmission down, it would also help reduce infections, but the reality is this vaccine is not going to be 100% effective in prevent infection and that's why we need to continue thinking about other measures to prevent infection as long as we have significant transmission as we have now in the country. >> is that the case for boosters for all? >> i think so. i think it emphasizes that boosters may help. we don't know for how long those boosters are going to continue providing that level of protection. the data from israel suggests after you get a booster, you have 11 point decrease in the risk of infection. that may be helpful. it may go away after a couple of months. we don't know what's going to happen six months after you get your booster. >> big picture, dr. fauci saying over the weekend, you know, we seem to be turning the corner on this latest delta surge and those numbers are on our screen there, you know, number of deaths down 12%. we're also seeing number of infections further down. do you think folks at home watching now should take some comfort in those numbers? >> well, we're coming down, but i think, you know, we're coming down from a very high peak, jim. the reality is we still have a lot of cases, a lot of hospitalizations, a lot of deaths. i would like to see daily cases in the 10,000 to 20,000 new cases. i would like to see deaths down to 100 deaths a day. we were almost there in late june, early july, and if we get down there, i would take total comfort. at this point in time, i think there is still a lot of transmission, particularly in many states here in the southern u.s. >> you know there is 18 months in everybody, though is looking for some sense of prepandemic normalcy. whether we get back there i think is a separate issue. as we're looking for that i'm curious your take on this holiday guidance that the cdc says was posted in error. we were talking this all felt very 2020. seemed to be really out of touch with where we are as a country right now. that misstep by the cdc, what is your -- what is your take on that and what it does overall, right, to how much people are going to consider any further recommendations when we do get closer to the holidays? >> well, you know, my advice to people to prepare for the holidays is get everybody vaccinated. your number one, two, and three thing you need to do is vaccinate everybody in your hous household. if you have people under the age of 12, you can't do that. vaccinate your kids down to the age of 5 because if everybody is vaccinated in the household, i would say you can meet very safely. my advice is if you have doubts about it, you can also use rapid testing. i think using testing before you get together is actually a very good strategy. the cdc also talks about -- i like meeting outside. i like meeting outside if it is possible. but there is some areas of the country where that is not possible. >> listen to the doctor, get vaccinated if you're not yet. dr. carlos del rio, thank you very much. coming up next, a whistle-blower is exposing the torture of up to 2 million minorities in china's western xinjiang region. the result of cnn's nearly three-year long investigation. it is amazing this is happening in the 21st century. that is next. ♪ ♪ to each their own love. the vera wang love collection.

>> translator: yes. everyone uses different methods. >> reporter: for years, stories of arbitrary arrests, unspeakable cruelty and mass internment camps have been trickling out of china's xinjiang region. testimonies from people like this man. when you were detained in 2013, what was your main job? >> kindergarten teacher. >> reporter: police took him from his uyghur language kindergarten. >> put me in the -- this is the interrogation room and inside iron cage there is a chair, you're shackled, your feet are shackled. >> reporter: he said police accused him of espionage, plotting against the chinese government and the crime of separatism and they demanded a confession. >> just confess, just admit what you have done. it is good for you. >> reporter: now, for the very first time, cnn has spoken to a former chinese police officer who claims his job was to arrest and extract confessions from ethnic uyghurs in xinjiang. >> translator: some cops would play the good cops and some would play the bad cops. after we beat them, we would offer them a cigarette. >> reporter: did you have to be the bad cop sometimes? >> translator: of course. >> reporter: the man who asks to be called jiang says he worked more than ten years as a cop, before fleeing china after growing disillusioned with the ruling communist party. i met him in a european country. he wore his police uniform to authenticate his story but does not want to be identified to protect himself and relatives that are still in china. to prove that he was a chinese police officer, jiang is showing me many photos of different police badges, training certificates, even portraits of his graduating class at police academy, images that we cannot show on television because they would reveal his identity. jiang says he was sent from his home province to work in xinjiang three times during which he was ordered to arrest hundreds of suspects, all of them ethnic uyghurs. how were the interrogations being conducted? >> translator: beat them, kick them, beat them bruised and swollen, knock their heads on the radiator, police would step on the suspect's face and tell him to confess. >> reporter: jiang says some suspects were as young as 14 and all of the detainees were beaten. were the suspects all men? >> translator: men and women. >> reporter: did you witness women being beaten? >> translator: yes. >> reporter: cnn cannot independently confirm jiang's allegations. nor those of the kindergarten teacher who says in addition to beatings, he was raped on his first night of detention by chinese prisoners who followed the orders of prison guards. >> it is very bad. >> reporter: this was prisoners who sexually assaulted you? >> yeah. the prisoners. >> reporter: more than one? >> more than one. yeah. like, just first of all they surrounded me and the police there ordered me to take off my underwear and -- >> and bend over. >> and bend over. don't do this. don't do this, i cried. please don't do this. and then, like, one of -- i don't know -- hold my hand, like this. >> reporter: jiang, the police officer who fled china, describes in graphic detail methods of sexual torture that he says police officers used. >> translator: if you want people to confess, you use the electric baton. we would tie two electrical wires on the tips and set the wires on their genitals while the person is tied up. the result is better. >> reporter: he also says police sometimes ordered prisoners to sexually assault detainees. >> translator: we call it an in prison investigation. >> reporter: the chinese government insists it is battling violent extremism in xinjiang. beijing also denies any human rights abuses whatsoever are being committed there. >> translator: i want to reiterate the so-called genocide in xinjiang is nothing but a rumor backed by ulterior motives and outright lie. >> reporter: but jiang says he got double his normal salary to join tens of thousands of other police sent to xinjiang as part of the government crackdown. how many of the people that you arrested in xinjiang do you think were actually violent extremists? >> translator: none. >> reporter: none? >> translator: xinjiang is not a war zone. those people are our fellow citizens, not foreign enemies. >> reporter: if you didn't carry out the arrests, what would happen to you?
