first fully what and when, the cambridge analytica whistle—blower chris wylie has given an account thatinconsistencies with the account given by cambridge ghouta and facebook. the second issue is public safety, we live in a time when a few firms have become wealthy by amassing troops of personal data and consumers need to realise that every time they go online david and digital footprint every time they go online david and digitalfootprint and every time they go online david and digital footprint and individuals, companies and governments can use that data to do things they might not like. the third layer is the politics. we have to regulators in britain looking at whether cambridge analytica was involved in the brexit referendum. in america the questions about their role in the trump election. if it is proven as cambridge analytica claim that they use psychological profiling to influence voters, if that is to perhaps the fragility of western democracy owes as much to our online habits as our offline once. thank you. now time for the sports news. the semifinals of the fa cup will see ma

this morning the founder, chris wylie whose no longer with the company, the company met to gather dateters. this data was voted to take advantage of people's mental vulnerables and this is a company he says took fake news to another level. >> when i show you an ad for a candidate tbts, hi, i'm so and so i and approve this message. what cambridge analytica is works on creating a web of disinformation on line so people start going down the rabbit hole of clicking on blogs, websiting et cetera that make them thing certain things are happening that may not be. >> cambridge analytica says it fully complies with facebook terms and service. wylie, the guy you just heard from there is quoted to be a disgruntle employee and is speaking to the media in an attempt to hurt the company. you might have heard facebook banned c banned cambridge analytica back on saturday night. facebook says it's committed to enforcing its policies in protecting people's information. >> we shall just say, almost in the time we went on the air in the last ten minutes, next has talked to corey lewandowski about cambridg

>> and i mentioned chris wylie at the reporter from our parters in the kux-- in the u.k.dinary testimony. what did we learn from him yesterday that we don't know before about the expense of this and the reach of this data operation? >> he had given us the number 50 million. what he testified to u.k. parliament yesterday was that it could be many, many more than that 50 million number. so it is really extraordinary, the scope of this breach. >> we look at colorado here. and i know oregon has been invoked. there is still a lot yet to be determined. so there is a lot of forensics happening at this point about where this data is. >> that is exactly right. cambridge analytica said they are deleting and now blaming rogue employees who have taken the data and it clearly still exists but we've learned that cambridge analytica had employees imbedded either with state republican parties or with campaigns across the country. so you have foreigners working to help republican candidates get elected in the 2014 mid-term elections. >> and thank you very much. appreciate that. that is an

people like chris wylie, former cambridge research esh at analytica.described how the company worked. >> imagine i ask you and say hey, if i give you $1 or $2 can you fill out the survey, do it on the app. and you say fine. i don't just capture responses. i capture information about you from facebook. and then crawls through your social network and captures the data. by you filling out my survey, i capture 300 records. reporter: the users facebook friends were spied on without consent. their likes, gender, sexual orientation and political leanings. everything was gathered. on twitter, facebook executive andrew bosworth denied climbs of a data link saying no passwords or information were stolen or hacked. friday, facebook announced that it had suspended cambridge analytica. that is not enough for politicians in britain and the us. they want to tackle the issue and confront those responsible. brent: facebook is a big company. we'll see reactions at the stock price. let's bring in our correspondent at the us stock commavening. this is bad news for faceboo

chris wylie, who worked with this company, cambridge analytica, and he of course claims that 50 milliond four years ago, facebook pushes back hard and said there was no breach, definitely, of its data, and says people, when theyjoined this app, they did so knowing notjust there but all of their friends personal information would be tapped into. they are not updating the statement in the light of comments from the chair of the select committee. as for cambridge analytica, have not heard from them, they say they did not use any of the information that they harvested from this infamous app, in the us presidential election of 2016 and that they only used legally acquired data, fairly, in also consensus. voting is under way across russia in the country's election, in which president putin is expected to win a fourth term in office. there are several other candidates but his main rival alexei navalny has been barred from taking part after being convicted of fraud, a charge he says was politically motivated. from moscow richard galpin reports. richard, obviously one of the key things about the

we're expected to hear from whistle blower chris wylie in london. we don't know what he's going to say, we don't know what's going to come out of this press conference but he may have a little something more about the story in "the washington post". wylie and other staffers say cambridge assigned dozens of foreign citizens to provide messaging device. why does it matter? that could violate u.s. elections which limit four nationals getting involved in political campaigns here at home. this.com is coming. the calls are getting louder from congress for the facebook ceo to testify. i want to wrap it up with jo ling kent who has more. >> mark zuckerberg is expanding his apology tour. facebook this morning confirming it does have the ability to track your phone call and text messages if you have an android device. >> i don't think facebook has been fully forthcoming. >> the top zpat on the intelligence committee wants ans. >> mr. zuckerberg needs to come and testify. he said he will do it if he's the right person. i've got experts on my staff that you don

so when chris wylie says that dr kogan was using apps from people who had no idea on facebook, is heg? well, i think, my understanding is that dr kogan sought permission from the people who filled out the survey and they were then giving up data on their friends. let me point out that this is no different to what barack obama's campaign were doing in 2012. the obama campaign produced a facebook app that requested their supporters to give up their facebook data and also allowed them to give up data on their... they knew they were doing it. exactly, and it's exactly the same. and you're saying everyone you asked knew they were giving up their data. well, everyone, certainly — let me clear up, we didn't ask everyone. everyone that dr kogan engaged with, my understanding is that they knew they were giving up their data and they would have signed some sort of permission for that. why do you think channel 4 then has been filming an undercover sting to prove that you had involvement in, uh, an unethical way of using people's most intimate and personal data ? well, i think... look i can't sp

improperly obtained facebook data from tens of millions of americans, according to whistle blower chris wylie one of the first clients of cambridge analytica to buy into the psychographic messaging that was developed using the 50 million facebook profiles that were misappropriated. >> a spokesman for john bolton's super pac denies knowing of any alleged impropriety by cambridge analytica, and the contract stipulates that cambridge analytica would follow the law and obtain all necessary permits. that contract, obtained by cnn, shows the bolton super pac in 2014 initially paid cambridge analytica more than $450,000 for behavioral microtargeting with psychographic messages. in other words, using data in an entirely new way. >> you're not trying to change people's votes or win people's votes at that time? you're trying to change their minds? >> you change their perspective. we want to change their perspective and change how they see things. this is a really key element of what cambridge analytica does. >> reporter: for example, cambridge analytica used facebook data to identify groups in arkansas

. >> reporter: the furor began over the weekend, after a former cambridge analytica employee, chris wylieid the company used the information to influence voters behavior. yesterday, he spoke with nbc news' "today" program:hi >>data was used to create profiling algorithms that would al to explore mental vulnerabilities of people, and en map out ways to inject information into diffe streams or channels of content online, so that sople started things all over the place that may or may not have been true. >> reporte the "new york times" reported that facebook failed to inform users whose data had been taasn for as long wo years. facebook has pushed back, saying "thelaim that this is a data breach is completely false." the company said users chose to share information. it also said it has hired auditors to make sure the data has been destroyed as promised. in now-deleted tweets, the company's chief security officer, alex stamos, admitted a researcher "lied" about how he would use the da. according to the "times," stamos plans to leave facebook later this year. the social media giant was alread

. >> well so, ali, the first point is when chris wylie, the whistleblower tells you facebook has not embraced him or accepted his guidance for digging into this thing, that is precisely the same experience that i had in 2016 when i went to the them in october before the election and i continued for three months there after trying to get them to recognize there was a systemic problem with the business model and algorithm to allow bad actors to inflict harm across areas on innocent people. so i'm not surprised that they have not accepted the offer from wylie. >> but back then, they blew you off and if anybody else told them, they blew them off. and now the emperor has no clothes. everything you've been on here telling be many facebook a company in which you were an early investor and continue to invest has come to be true. >> and much worse. >> mark zuckerberg can sort of apologize and sort of say he's sorry around the edges. that wasn't a full-throated, hey we've got a problem. >> it was worse than that. because there were a couple of things he said. i can't believe -- i couldn't have

. >> reporter: chris wylie helped found aim bridge analytica. the deal was run by jared kushner. and by brad parscale who now runs trump's 2020 election efforts. >> it's really important that americans understand what has happened with their data and their private information. >> reporter: cambridge analytica calls his comments an attempt to hurt the company. wylie left cambridge before the 2016 election. beginning in 2014, cambridge analytica funded a personal test on facebook and paid people to take it. this allowed the company to gather personal data from participants' facebook themes. but what users didn't they cambridge was also collecting data about their facebook friends, according to wylie. the alleged goal, use the data to influence the views of american voters online. in hidden camera video, from our british partner itn, channel 4, a cambridge executive told a reporter posing as a perspective client about the company's goals. >> it's no good fighting an election campaign on the facts because actually it's all about emotion. >> reporter: another executive boasting of the

i want to go to a byte on what chris wylie said on what bannon in particular wanted out of this relationship for culture. that's what he wanted. and we offered him a way to accomplish what he wanted to do. which was -- which was change the culture of america. >> and kurt, having worked for breitbart, change the culture of america and change it into what? >> steve has talked be his goal of destroying, deconstructing the administrative state of this country. tearing down the pillars, whether free press, mainstream media, establishment of political parties that's his goal all along. he wants to use social media and facebook to wage that war. to target people manipulate them. to advance the idea really of feeding them their brand of news what we would call fake news and infiltrate how they think. >> infiltrate how they think to turn people into what? what does he want people to believe in? will he wants people to be soldiers in his army of disruption. against sailing against everything that is normal, and establishment, he wants to use these people to amplify their rhetoric. the thing that stand
