your testimony says that alexander kogan's app has been banned. has he also been banned? >> yes, my understanding is he has. >> so if he were to open up another account under a name, and you were able to find it out, that would be closed down? >> senator, i believe we are preventing him from building any more apps. >> does he have a facebook account still? >> senator, i believe the answer to that is no, but i can follow up with you afterwards. >> okay. and with respect to cambridge analytica, your testimony is that first you required them to formally certify they deleted all improperly acquired data. where did that formal certification take place? that sounds kind of like a quasi official thing to formally certify. what did that entail? >> senator, first they sent us an e-mail notice from their chief data officer, telling us they didn't have any of the data anymore, they deleted it and weren't using it, and later followed up with i believe a full legal contract where, they certified that they had deleted the data. >> in the legal contract? >> yes, i believe so. >> okay, a

alexander kogan linked to st.ersburg state university, kind of a link to the russian government. basically, he does research, and it was provided to cambridge analytica. he's basically saying that, you know, i actually am not the person who is in trouble here. this has to do with facebook policy. here's what he had to say to savannah guthrie earlier this morning. >> at the time, we didn't think we were doing anything wrong. it was the normal business as usual practice. i think right now, absolutely, it is viewed as wrong. now that we know how people feel about it. >> facebook called you a fraud and liar. they painted you as the culprit here. what's your response? >> my perception, it's pr spin. i think they're trying to distract people from realizing that what we did was the normal practice back then. it was a pretty friendly relationship with facebook. i had a lot of things to lose by making them upset. >> you can see that he felt he was following policy. he was doing what he thought facebook not only wanted but

was alexander kogan able to get both sets of data. mark: it was just a subset of what was entered by the person. a subset of the 95 categories of data that you keep. ,ark: the app developer says this is the type of data i am asking for. including public information like your name, the pages you follow, other interests. has to developer disclose that upfront and you agree to it. an answer to a: couple other senator's questions, you talked about facebook starting this -- storing this data. and you talk about it being in the system. inonder if outset of the way which alexander kogan was able you,cess this eta, whether facebook, could be vulnerable to a data breach or hack. there are many kinds of .ecurity threats including people trying to break it our security system. senator baldwin: you believe that you have been hacked, would you have the duty to inform those impacted? mark: yes. knowor baldwin: do you whether alexander kogan sold any of the data he collected with anyone other than cambridge analytica? mark: yes, we do. he sold it to

you're listed as both alexander kogan and alexander spectre. can you explain that? yes, sir.rried and my wife and i decided that it didn't make sense for me to take her name, or for her to take my name. so we said let's choose a new last name. and since we're both religious and scientists, we thought the idea of light made a lot of sense. so we were looking for something related to light. then my father was sadly sick at the time and one of his surgeons at the time was named jason spectre. we thought that is a really cool sounding name. it also kneels down the theme of light, because of spectrum. and so we decided on spectre as a derivative of a spectrum, as a symbol going for it as a family. you know that spectre is the evil organisation in the bond film? it's an unfortunate coinicidence. did you know that at the time? i did not. when the controversy broke, facebook described dr kogan‘s worked as a scam and a fraud and asked him to delete the data he's obtained. in my view, facebook's comments are pr crisis mode, right? i think, i don't believe they actually think these thin

i wonder if outside of the way in which alexander kogan was able to access this data. >> there are many kind of security threats that a company like ours faces, including people trying to break into tour security systems. >> if you believed that you had been hacked, do you believe you would have the duty to inform those who were impacted? >> yes. >> do you know whether alexander hogan sold any of the data he collected with interest in other than cambridge analytica? >> yes, we do. he sold it to a couple of other firms. >> can you identify them: >> yes. one called unoya, and there may have been a couple others as well. >> and then how much do you know or have you tried to find out how cambridge analytica used the data while they had it before you believe they deleted it. >> since we just heard they didn't delete it about a month ago, we kicked off an internal investigation see if they used that data in any of their ads. that investigation is still under way. and we'll -- we can come back to the results of that once we have that. >> i want to switch to my home state of wisconsin. accordin

cambridge analytical data breach scandal first of all speaking to a parliamentary committee dr alexander kogan he's the man who produced the app that was used to harvest the data of some eighty seven million facebook users and then illegibly passed it on to cambridge analytical for use in influencing the donald trump campaign and following that swiftly it was a press conference given by cambridge analytical defending or dealing with what it described as ill informed and inaccurate speculation about the company well alexander kogan insists as he has done before that he did nothing wrong back in two thousand and fourteen both sides he said knew precisely what was going on what he was doing no one raised any objections then he says he's being made a scapegoat by facebook that describes him as a liar and a fraud his product as a scam and cambridge analytical that says the data he produced was in effect will take a listen to this exchange from the briefing in which the committee suggests that his motivation may in the end have been commercial game essentially the payments on the part and soon to be

analytical says he wasn't upfront about how the data was collected as a say in the middle east alexander kogan will find out more about him today he insists he did nothing wrong and just briefly jonah i mean as you say he's been implicated in providing the means for the scandal so is what he did illegal i think that's an incredibly difficult question to answer this is a largely unregulated space of course the digital world that is one of the crucial issues under examination now there are very few rules governing what facebook does with data and of course facebook has existed from the beginning of obvious exhibit existence accumulating aggregating data using it for advertising models and so on and cambridge analytic what it was doing in gathering data and then targeting political ads that particular subsets of voters based on their likes and dislikes is the sort of thing that political parties have been doing since the beginning of democracy it's a question of where these two things intersect and whether that data was improperly used in other words not with the knowledge of the people giving it

said that he to be instrumental in electing donald trump well i was alexander kogan being probed here by this committee that has heard from facebook and cambridge i live and a little before he insists he did nothing whatsoever wrong that can that facebook was totally aware of what he was doing that cambridge analytical ensured him should in that it was doing nothing illegal and yet he is in his words being scapegoated by both as scrutiny amounts against that well the committee scrutinizing him indeed alexander koch and looking at his methods and motivations in particular looking at the extent to which he may have been motivated by commercial interests because he was being paid not in money for these ads but b. being allowed to keep the data for his own future use he had a couple of largely failed companies it has to be said said that it attempted to monetize personal data that aspect of it would give him essentially a motivation perhaps and then the methodology has been suggested by the committee that he was less than honest that he misrepresented the nature of the app that people usi

harm us and hack our democracy facebook made it too easy for a single person in this instance alexander kogan to get extensive personal information about eighty seven million people he sold this data cambridge analytical who used it to try to sway the two thousand and sixteen president presidential election for the trump campaign and facebook made itself a powerful tool for things like voter suppression in part by opening its platform to app developers with little or no oversight but it gets worse the fact is no one knows how many people have access to the cambridge analytical data and no one knows how many other cambridge analytical is are still out there shutting down access to data to third parties isn't enough in my opinion facebook and many other companies are doing the same thing they're using people's personal information to do highly targeted product and political advert. and facebook is just the latest in a never ending string of companies that vacuum up our data but fail to keep it safe and this incident demonstrates yet again that our laws are not working making matters worse repub

presidential election well alexander kogan insists he did nothing wrong he's being targeted he says scapegoated by both facebook and cambridge and a little girl who claim that they weren't entirely aware of how the information was gathered and b what it use it was eventually going to be put to the denies all of that and the committee probing his motivation and methodology looking at his perhaps commercial interests or motivations he had a couple of companies that he'd set up to use personal data for commercial purposes he was paid indeed for this app not in money but by being allowed to keep the data essentially to be able to use it in future for commercial purposes and then also his methodology the committee suggesting he wasn't entirely honest and open with users of the after the misrepresented its purpose by not making it specific that it was going to have political uses later on he said well looking back i should have perhaps been more critical about the way that the app was presented the way it was all set up but his essential defense here is that for years and years across the lagoon vall

in 2015 we heard the report that alexander kogan had sold data to cambridge analytica. decisionou part of the not to inform your users? >> i do not remember a conversation like that. >> were you aware of anyone in leadership and facebook that was in the conversation where the decision was made -- >> i'm not sure whether there was a conversation about that. in 2015 we banned the developer and delete all the data and stop using this with kimber general in a cup. >> -- cambridge analytica. >> this relates to transparency. in terms of how their personal information has been misused. i'm also concerned when he personally became aware of this, did you or senior leadership do an inquiry to find out who it facebook had this information, and did they not have a discussion about whether or not the users should be informed? >> in retrospect's i think we clearly viewed as a mistake. we do not base it on false information that we thought the case was closed and the data had been deleted. that's my understanding. >> a couple of things here, this is not a classic data breach to find a

presidential election, alexander kogan the academic at the heart of all this flatly denies and feelshis didn't help win any election for donald trump. the data he harvested, he said actually it was unlikely the data helped the trump campaign. they tried it with ted cruz before the trump campaign. ted cruz's campaign was dissatisfied with it. it is not efficient micro targeting. why? because you wouldn't use this data to run political ads on facebook. he was basically saying to be efficient you use facebook's own tools. you don't build your own. he thought it would have been very unuseful in terms of winning the 2016 presidential campaign. that was notable and also the fact that he was saying, look. facebook should have known that i was passing on data to third parties. when he became a commercial entity not when he was in academia but became a commercial entity he put it in terms and conditions of the app he was making that he would pass on data to third parties. in fact many companies do that. he says he challenged during other interviews post this testimony to go and check big comp

app was designed by alexander kogan and passed on to cambridge analytica and gave them 50 million usersusersse 50 million facebook says hardly any of them , are from the eu or the u.k. 90 that is like mark zuckerberg feels he does not need to come in front of parliament here. emily: facebook is getting its ducks in a row to lobby lawmakers. they are hiring for 11 different positions on capitol hill. talk to us about the extent of facebook's lobbying efforts how that compares to other tech companies in what they are trying to change. >> i think the first thing we have to note is that facebook's budget spent on lobbying in d.c. is so much smaller than these companies that have been doing it for years. googles and apples of the world. facebook is pretty slow to join the party. in the past, they did not have a contentious relationship with washington. they grew up in barack obama's presidency. now they are sort of realizing that they need to make nice and they need to figure out how to get in on these issues before they come to a head. most of all how ,to explain -- most of all, how to expl

was atr alexander kogan cambridge university when he was doing these particular apps, inventing them,rs. the users. notably, there was firm rhetoric coming from cambridge university in response. they said they were rather surprised that mark zuckerberg had an overal not known overallt was going on at the university of cambridge. he himself is saying they need to understand whether you say something that was going on at cambridge university bad overall and whether they require further action from facebook. in response, cambridge university said, look, we have made them aware. not only did we write them a letter on the 21st of march desiring them to provide evidence. they also said we have been publishing findings of our data and our research since 2013. you should know about this. emily: last question, we know the facebook cto will be testifying in the u.k. in a few weeks. we have 30 seconds left. how will it be different from what we saw here? alex: the problem is there are a lot of different lawmakers asking questions and they were constrained by time. they had four minutes, five min

>> yes. >> i want to show you the terms of service that alexander kogan provided to facebook. and note for you that in fact facebook was on notice that he could sell that user information. have you seen these terms of service before? >> i have not. >> who in facebook was responsible for seeing those terms of service that put you on notice that that information could be sold? >> senator, our app review team would be responsible for that. >> has anyone been fired on that app review team? >> senator, not because of this. >> doesn't that term of service conflict with the ftc order that facebook was under at that very time that this term of service was in fact provided to facebook, and you'll note that -- that the ftc order specifically requires facebook to protect privacy. isn't there a conflict there? >> it certainly appears that we should be aware that this individual submitted terms that were in conflict with the platform. >> it was willful blindness, heedless and reckless which amounted to a violation of the ftc consent decree. would you agree? >> no, senator. it's not my unde

. >> alexander kogan is with us from london. good morning to you., savannah. >> this story can get real technical real fast. let's try to make it as simple as possible. you, in many tellings of this story, are the original bad guy. you took the data and sold it to cambridge analytica, the political firm. was it wrong to do that? were you wrong? >> at the time, we didn't think we were doing anything wrong. that was the normal business as usual practice. right now, it's viewed as wrong, now that we know how people feel about it. >> when you say it was the normal practice, you're saying that's how things were really done. it was clear. facebook says you are not to sell this data and yet, you sold the data. >> the amazing thing about facebook's policy, it's presented to developers just like terms of service are presented to the users, hard to find, easy to miss. most companies, if you go and look at apps right now, they have language that is in direct contradiction to that exact clause. so, arguing that's actually facebook's policies, fascinating. if yo

at the time, in 2015, we heard the reports that this developer, alexander kogan, had sold data to cambridge analytica. >> were you part of a discussion that resulted in a decision not to inform your users? >> i don't remember a conversation like that. >> are you aware of anyone in leadership at facebook who was in a conversation where a decision was made not to inform users, or do you believe no such conversation took place? >> i'm not sure whether there was a conversation of that, but i can tell you with the thought process was. when we heard about this, we banned the developer and demanded they delete the data and stop using it. same with cambridge analytica. >> i'm talking about the notification to users. this relates to the issue of and theency relationship of trust. informing the user about what how theirn terms of personal information has been misused. i am also concerned that when you personally became aware of this, did you or senior leadership do an inquiry to find out who at facebook add this information, and did they not have a discussion about whether or not users should be info

>> well, congressman, the issue of cambridge analytica and alexander kogan before we ramped those programs up dramatically. but one thing i think is important to understand overall the sheer volume of content on facebook makes us, no amount of people that we can hire will be enough to review all of the content. we need to rely on and build sophisticated ai tools that can help us flag certain content. we're getting god -- good in certain areas. one of the areas i mentioned earlier terrorist content where we have ai systems that can identify and take down 99% of the al cade and isis-related content in our system before someone, a human flags it for us. i think we need it do more of that. >> the gentleman's time expired. the chair recognizes gentleman from california, mr. mcinerney. >> thank you for sevenning before the house and senate committees. i know it as long and grueling process. i appreciate your cooperation. i'm a mathematician spent 20 years in government on technology including algorithms. i'm deeply committed and invested here. i'm going to follow up on a earlier question. is the

what was fascinating about seeing the clip of alexander kogan and you think, go goode, lord, you the world is in the hands of these two young men. >> when i think about facebook has all the most important data, we've studied the data. what dpas bo what facebook and instagram have and dating apps is who i want to be so the world likes me. but what google and amazon have is that i'm buying tube socks, underpants and, you know, athlete's foot cream. but when you talk about valuable data, does facebook and dating apps and social media really have valuable data or our fake lives? >> here's what i think is more interesting than that is how is spending so much time on these apps changing our behavior? >> there you go. >> and that is what fascinates me. it's particularly interesting because dating apps are a fantastic way to meet somebody but they can't be the only way. and what you discover and i've talked to hundreds of women and some men in the making of this book is how much time people spend online to your point about data matching with someone who they think they know and then they hav

>> yes. >> i want to show you the terms of service that alexander kogan provided to facebook. and note for you that in fact facebook was on notice that he could sell that user information. have you seen these terms of service before? >> i have not. >> who in facebook was responsible for seeing those terms of service that put you on notice that that information could be sold? >> senator, our app review team would be responsible for that. >> has anyone been fired on that app review team? >> senator, not because of this. >> doesn't that term of service conflict with the ftc order that facebook was under at that very time that this term of service was in fact provided to facebook, and you'll note that -- that the ftc order specifically requires facebook to protect privacy. isn't there a conflict there? >> it certainly appears that we should be aware that this individual submitted terms that were in conflict with the platform. >> it was willful blindness, heedless and reckless which amounted to a violation of the ftc consent decree. would you agree? >> no, senator. it's not my unde

connecticut's richard blumenthal asked about facebook's deal with alexander kogan, whose app gave cambridge analytica its access. >> i want to show you terms of service that kogin provided to facebook. i want to note for you that in fact, facebook was on notice that they could sell that data. did you see this? >> i did not. >> who was responsible for this? >> our app review team. >> was anyone fired from this team? not for that. >> reporter: illinois senator dick durbin:ou >> woulde comfortable sharing with us the hotel youig stayed in last? >> ( .laughs ) >> if you messaged anybody this week, would you share with us the names of the people you've messaged? >> senator, no, i would not choose to do that publicly here. >> reporter: zkerberg was twice pressed on whether facebook tracks users across devices anafter they leave the platform. he hesitated to answer. >> there has been repo facebook can track a user's internet browsing activity en m.ter that user has logged off the facebook platf can you confirm whether that's true? >> senator, i want to make sure i get this accurate. it's better to

you have told us today and you have told the world that facebook was deceived by alexander kogan whenorrect? —— so the information to cambridge analytical. yes. i was reading information that was provided. in notes from you that in fact facebook was on notice that he could sell that user information. have you seen these terms of service before?” have not. who in facebook was responsible for seeing those terms of service that puts you on notice? that information could be sold? or opera review team would be responsible for that. has anyone been fired on that application review team ? been fired on that application review team? not because of this. doesn't that term of service conflict with the ftc order? that facebook was under at that very time? that this term of service was in fact provided to facebook, and you'll note that the ftc order specifically requires facebook to protect privacy. isn't there a conflict in there? it certainly appears that we should have been aware that this app developer submitted a term that was in conflict with the rules of the platform. what happened here wa

connected to the facebook data misuse scandal has appeared before a british parliamentary committee alexander kogan is linked to the u.k. based cambridge analytical firm that's being accused of improperly accessing the information of nearly ninety million users through facebook but let's get more now from jonah holly joins us live from london journal so what more do we know about alexander code and what's he been saying to the committee. well it was interesting testimony from him he's the man of course who built the app that was used to harvest the data of hundreds of thousands of users of facebook but at the time in two thousand and fourteen he was also allowed to harvest the data from all of their friends and that gave him a magnificent dataset of some eighty seven million people which was then passed on allegedly to cambridge analytical to help them build their their micro targeted models to help influence voters principally in the u.s. election while i was on a cogen insists that he did nothing wrong that everybody knew what he was doing no one complained he says he didn't breach any terms of s

our-- at the time in 2015 we heard this report that alexander kogan had sold data to calm bridge analytica. that's a violation of our terms. >> were you part of a discussion that made the decision not to inform users. >> i don't remember a conversation like that. but the reason why-- >> are you aware of anyone in leadership at facebook who was in a conversation where a decision was made not to inform your users or do you believe no such conversation ever took place? >> i'm not sure whether there was a conversation about that, but i can tell you the thought process at the time of the company, which was that in 2015 when we heard about this we banned the developer and we demanded that they delete the data and stop using it and same with cambridge analytica and they told us they had. >> i'm talking about the notification of the users. this relates to the issue of transparency and relationship of trust, informing the user about what you know in terms of how their personal information has been misused. and i'm also concerned that when you personally became aware of this, did you or senior leade

a whole program associated with cambridge university where a number of researchers, not just alexander kogan although to our knowledge she's the only one who sold the data to cambridge analytica, there are other researchers building cap so we need to understand if there was something bad going on with temperature university overall that will require stronger action from us. rep. engel: you mentioned in your remarks hate speech. we have seen the scale of extremism. decade, partially because of the expansion of social platforms can whether it is a white supremacist rally in charlottesville that turned violent, or ethnic cleansing in irma that resulted in the second largest refugee crisis in the world. foreign orre of domestic terror organizations, hate groups, criminal or extremist networks that have scraped facebook user data, and if they have and do it in the future, how would you go about deleting it? mr. zuckerberg: congressman, we are not aware of any specific groups like that that have engaged in this. we are, as i have said, conducting a full investigation of any apps that had access to

presidential election well alexander kogan insists he did nothing wrong he's being targeted he says scapegoated by both facebook and cambridge and the little guy who claim that they weren't entirely aware of how the information was gathered and b what it use it was eventually going to be put to he denies all of that and the committee probing his motivation and methodology looking at his perhaps commercial interests or motivations he had a couple of companies that he'd set up to use personal data for commercial purposes he was paid indeed for this app not in money but by being allowed to keep the data essentially to be able to use it in future for commercial purposes and then also his methodology the committee suggesting he wasn't entirely honest and open with users of the app that he misrepresented its purpose by not making it specific that it was going to have political uses later on he said well looking back i should have perhaps been more critical about the way that the app was presented the way it was all set up but his essential defense here is that for years and years across silicon valle

of course now we know that's exactly what happened. 2014 alexander kogan used a survey at and was able access facebook users and friends data was able to obtain personal information about and up to 87 million facebook users. kogan sold that data to cambridge analytica political consulting firm that worked with the trump campaign and the brexit campaign and brag about influencing other political outcomes in mexico australia and kenya and based on recently released under recordings have sent text workers as part of its toolbox for influencing political candidates. we learned about how cambridge analytica had obtained this data we have also learned that facebook is known about cambridge analytica since late 2016 but did little other than that mending cambridge analytica certified that it has done so. while facebook continue to allow cambridge analytica to advertise on its platform until just before last month story broke. the stories story is led to a firestorm river new concerned of the privacy on line generally and facebook specifically. the controversy had been raging for over year abo

the british professor alexander kogan four years ago ran a personality test on facebook to collect data from millions of americans. now facebook claims kogan broke company policy by sharing that information with a political consulting firm that was working with the trump campaign. kogan admits to "60 minutes" what he did wasn't right or wise. >> if i had any inkling that what we were going to do would destroy my relationship with facebook i would never done it. this is the blindness we had back then. >> yeah. facebook's calling their relationship complicated now. kogan also said what he did was not hacking because facebook created tools for developers to collect data. >>> parts of the florida panhandle are in cleanup mode after strong storms created a waterspout. >> it ripped the roof off at least one home as it came ashore in ft. walton beach. it flipped over boats as well. and pushed around and damaged a city pickup truck there left in the parking lot. the waterspout knocked down trees and utility poles, broke windows. there are no reports of any injuries. >> always amazing to see one

you have told us today and you told the world that facebook was whenved by alexander kogan he sold use information to cambridge analytica, correct? mark: yes. >> i want to show you the terms of service that he provided to facebook. and note for you that in fact, facebook was on notice that he could sell that user information, have you seen these terms of service before? >> i have not. >> in facebook was responsible for seeing those terms of service that put you on notice? >> hour after the team would be responsible for that. center, nobody has been fired because of this. of servicethe term conflict with the ftc order? that facebook was under at that very time? that the terms of service was in fact, provided to facebook and ftc orderote that specifically requires facebook to protect privacy. is there a conflict there? that we should be aware that this app developer submitted a term that was in conflict with the rules of the platform. washat happened here willful blindness. which he was an reckless amounted to a violation of the ftc consent decree. would you decrypt -- a great russian ma

when we talked about the data breach, 87 million people, that was a bad actor, alexander kogan, who puthird party app up where he signed a terms and conditions never to sell the data. he was able to ultimately access through the friends 87 million people. facebook has since changed that. if this were to happen again there would be 300,000 folks, not 87 million. these are people who willingly went to the app, took a quiz, and that exposed their data. but the third party app developers are required under the terms and conditions to never sell that data. this individual did sell it. they have since changed the way that works so they can't access friends of those participants. so i came away convinced that facebook us self-policing. he was very clear on how the privacy works and how users can in fact opt out of their data being shared and it is not that difficult to do. so i would agree with you, i don't see regulations or legislation coming through in the near future and we will continue to hold hearings as need be. they're operating under an ftc, federal trade commission consent decree fr

the otherr one isis the whole situation we are here is becaush third party app developer, alexander kogan, didn't velop follow-through on the rules.ow r he was told he can't sell the data. he gathered the data. and then he did what he's not s supposed to and sold that data. and it's very hard to anticipate a bad actor doing what they areh doing until after they have done it. and clearly you took actions ios after 2014. one so one real quick question is, what did change, in ten or 20 seconds, what data was being collected before you locked down the platform and how did that change to today? >> congressman, thank you. so before 2014, when we nounc announceded the change, someone could sign into an app and shar some of their data. but also could share some basicc information about their friends. and in 2014, the major change was we said now you are not abe going to be able to share any information about your friends. so if you and your friend happened to be playing a game today or on an app that listening to music together, then that app could have some information from both of you, because
