alexander cogan gained access to information from users who chose to sign up for his app. everyone involved gave their consent. people knowingly provided their information." apparently the problem came when they realize the information wasn't being used as they thought it would be for academic purposes but was being used for political targeting by a trump connected campaign consultant. charlie, what do you make of it? >> it's funny because i remember in 2004 when howard dean was first doing some of the data mining and he was harold as a hero. in 2008 and 2012, everybody was marveled -- marveled at obama's ability to use this kind of data mining this kind of data to reach voters. of course as soon as donald trump doesn't, it becomes a scandal. then everybody starts talking about needing to curb it or regulated or whatever. the truth of the matter is, that's the business these people are in. they are in the business of collecting people's personal data, selling it to people, to be mined so people can advertise or do whatever. >> shannon: katie, are we talking about apples an

speaking to cnn, alexander cogan, the scientist that collected all this information and sold it to cambridgebe a scapegoat to distract from bigger problems facing the company. >> we did collect 50 million people, but we only gave 30 million people. >> what kind of information about those 30 million people were you providing? >> basically their public profile. things like name, age, gender and location. and then these really noisy personality predictions. that was basically it. >> when you were offering your data to cambridge analytica, you knew who -- you knew what they did -- did you know what they were going to do with it? did you know what their interest was? >> no. i was pretty heavily siloed as far as clients. i found out about donald trump just like everybody else, through the news. >> what's also key to point out here is that former white house chief strategist steve bannon was vice president and secretary of cambridge analytica until he stepped down to run trump's campaign. today they're reporting bannon was part of this very program that collected all the millions of facebook users'

one of the other things that was pitched to the minister national related toere was some of cogan's russian research . it was about whether you could profile dispositional and then quantify that in data of people who are more likely to commit crime. i didn't continue working on the project because i got switched over. provided documentation on trinidad to the committee. the choir, the anonymized isp data. >> you mentioned lafayette. rica and visit the national corporation there. and not just come up with interiors. what that country. that country does not need any more tensions. could you explain more about done?he work was >> to be clear, that is not sclridge analytica, that is , or some iteration. not political work. -- i believe canada is the main funder. on information, operations, training, and also my understanding was they were doing counter propaganda work in the bullpen. nothing nefarious. >> there should be no suggestion that they have piggybacked on the back of that to do political work? >> not necessarily. they usedin lithuania some of their connections to do political work. my

what the guy, what cogan, he signed up to be an app developer. the reason you give app developers data is to they can make good apps on your platform. >> is facebook done saying we're not being a media company. >> i think facebook's done-ish saying they're not a media company. >> at this point you are just irresponsible and you need to get supervised. >> there is a whole bunch of users who don't care. >> nobody i know -- i got one thing from yesterday saying somebody shut down their facebook account. >> this is about regulators and government leaders getting involved. people are still going to be posting pick turs of puppies and looking for ex-boyfriends. >> should they sue cambridge analytica? >> are you answering the question where is cheryl sandberg? >> i would like to know, too. we haven't heard a thing during this whole mess. >> that's it for this hour of velshi and ruhle. >>> right now on "andrea mitchell reports," not again. days before a student-led march for gun safety, a student allegedly opens fire inside a southern maryland high schoo

cogan sent me a message saying he didn't want me to use it. i said ok, and that was that. ian: that was incredibly valuable data. christopher wylie: yes. but at the time, i wasn't even working in american projects. ian lucas: just so i'm clear, it's the same data that cambridge analytica had, that facebook now says they wanted them to delete. christopher wylie: yes. julian knight: the same day brought -- data, and you deleted it. did facebook ask you to delete it? christopher wylie: they asked a year later to confirm that i did. i sent a confirmation that i had. ian lucas: did facebook contact you again? or did they just except your word for it? christopher wylie: they accepted it. i followed up to make sure they were satisfied. they were, so it was only, they only started actually doing anything about it when they found out that the guardian and new york times were going to be publishing. ian lucas: did they contact you again at that stage? christopher wylie: yes. ian lucas: was that when they were getting heavy? christopher wylie: yes. they only started getting heavy wit

these are important questions as well as the links to luke oil and alexander cogan's links to st.niversity. >> we can try to put some of those questions to kylie. what are the key revelations that come out of this undercover video and great reporting? >> first of all, we've had a number of films. this was undercovering reporting that a couple of our team members went along and pretended to be skri lan kaen. cambridge analytica, we had four meetings with them. for the final meeting, alexander nix himself turns up. they talked about a whole series of dirty tricks about sending ukrainian women around to rooms where potential opponents could be filmed and that could be put out on the internet. they talked about bribery. they talked about how information doesn't necessarily need to be true. it just needs to be believable. and the way that you use the internet i think is really revealing. they talked about just putting things into the bloodstream of the internet that was kind of untrackable and untraceable. they described a world of using -- >> chilling. >> yeah. it's absolutely chillin

there's an academic at cambridge named alexander cogan, and he creates an app there is no spaces in thehe teams up with cambridge analytica, and they start paying people to download the app, use it and take the personality test that's on there. here is what's key about that app. it's not just the people who download the app and take the test that they can get information on they also start to scrape the facebook friends of everybody who used that app, and then according to facebook, they retained that data 2016 cambridge annual l littica that whistle-blower that we talked about, finally his story gets published in the "new york times," and facebook suspends cambridge analytica's accounts who better to speak to than someone who knows the ins and outs let's bring in kevin knight. kevin, good to have you here >> thank you for having me >> can you tell me what kind of data would came bring analytica have on the friends of the people who use this a.m. >> generally this kind of data is the things that would be interesting to an advertiser if you were looking to understand if somebody might be

one is making sure that evelopers like alexander cogan don't get access to as much information going forward. so we are doing a set of things that to restrict the amount of access that developers can get going forward. but the other -- because we need to make sure that there aren't any other cambridge analyticas out there or folks who are improperly access data. we're going to go now and investigate every act that has access to large amount of information from before we lock down our platform and if we detect any suspicious activity, we're going to do a full forensic audit and make sure that no one out there is improperly using dathes and that's the responsibility that we have to people in our community. host: here is so much that response saying he seems if not outright welcoming regulation or at least accepting of it. there are some really nuanced questions about how to regulate which i think are extremely interesting intellectually since zuckerberg who points the ipartisan honest ad act -- host: let's go of the doing of more regulation of facebook needed. kevin, facebook user. you
