zuckerberg: mr. chairman, thank you. as i mentioned, we're now conducting a full investigation into every single app that had access to a large amount of information, before we lockdown platform to prevent developers from accessing this information around 2014. we believe that we're going to be investigating many apps, tens of thousands of apps, and if we find any suspicious activity, we're going to conduct a full audit of those apps to understand how they're using their data and if they're doing anything improper. if we find that they're doing anything improper, we'll ban them from facebook and we will tell everyone affected. as for past activity, i don't have all the examples of apps that we've banned here. but if you'd like, i can have my team follow up with you after this. mr. grassley: you have ever required an audit to ensure the deletion of improperly transferred data and if so, how many times? mr. zuckerberg: mr. chairman, yes, we have. i don't have the exact figure on how many times we have.

what did you think about mark zuckerberg's testimony. >> caller: i thought mark zuckerberg did an excellent job. even when he evaded questions, i felt he was very attentive. there was some real sincerity that came across, some real surprise. sometimes he did evade questions, but i would say over all he did great. i was embarrassed, especially yesterday by the senators, by some of the questions and the repetitive questions that came in with their questions, i assume the staff prepared or they prepared with them. and it was very uncomfortable today many so of today, but mostly more yesterday, when the same question would be asked. because they didn't have an understanding to understand their question had already been answered and they asked the same thing. but mark zuckerberg was very patient. never said i already answered that. or this is the tenth time i've answered that. so i just felt in this situation the senators and the representatives would have been better served by taking an expert on their staff who is maybe an expert in technology, getting the questions they want, and let someone

hotel question, which shook zuckerberg durbin asked zuckerberg who he contacted that week and where he stayed last night which the ceo declined to answer dan primack said i think zuk is bli blinking out an sos signal so, some of them were more lighthearted a lot of people folki ipoking f zuckerberg >> he's young. >> 33. >> still like a grown-up these days, i think. zuckerberg got off easy. except for the hotel question. that is the one that connected with the audience. a lot of senators -- i mean this with all due respect, they seemed to ask questions like how does the app -- >> it was like tech support. >> like someone trying to explain how an engine worked, but never worked on a car engine so your mom. >> my mom said kate, what was facebook called when you were in high school? it was something different i said "the facebook?" >> that was the original name. >> she said it was something else wasn't it myspace. she was asking if they were the same they are ish, but not. >> i will defend your mother here, she is obviously very nice >> she's the best. >> facebook killed myspace effecti

zuckerberg: yes. rep. cardenas: something was brought to my attention recently that apparently facebook does in information toy augment the information you have on users to build around them. we recentlyrg: announced we are stopping working with data brokers as part of the at system. rep. cardenas: but you did do that to build your company? mr. zuckerberg: it is an industry practice, and examining our systems, we decided is not a think will want to be a part of. rep. cardenas: but you did engage in that as well? mr. zuckerberg: yes, until we announced we are shutting it down. rep. cardenas: it is my understanding that when the guardian reported on the cambridge analytica consumer issue, facebook started to see them they went forward with the story. did something like that happen? believeerberg: i don't -- i believe they may have been a factual inaccuracy. rep. cardenas: you checking the guardian and saint you do not to go with that story because it is not 100% factual? mr. zuckerberg: yes. rep. cardenas: t

zuckerberg: vonnie: yes -- mr. zuckerberg: yes. rep. doyle: emerging from practices the ftc said were unfair and deceptive, one was making facebook users private information public without notice or consent. claiming that facebook certify the security and integrity of certain apps when it did not. it enabled developers to access information about a user and their friends, correct? mr. zuckerberg: i am not familiar with all of the things the ftc said. rep. doyle: this is part of the consent decree. i am concerned that despite this consent decree, facebook allow developers access to an unknown number of users on facebook for years. potentially hundreds of millions and more. not only allowed but partnered with individuals and app developers such as aleksandr kogan who sold the data on the open market and the cup -- to cambridge analytica. plant tosaid that you audit tens of thousands of developers that may have been improperly harvesting data, and you said you would give all facebook users access to user controls that will be made availabl

zuckerberg: i do notmr. zuckerberg: -- mr. zuckerberg: i do not. rep. sarbanes: president trump at 5.9 million advertisements approved and secretary clinton at 66,000 ads. times as much on the current campaign which raises questions about whether the advertisement approval processes or inappropriately bypassed in the final months and weeks of the election by the trump campaign. i am worried the embeds may have facilitated that. can you say with certainty that facebook or any facebook employees working at campaign embeds did not grant special approval rights to the trunk campaign to allow that to upload a large number of facebook ads in the final stretch? mr. zuckerberg: we apply the same standard to all campaigns. rep. sarbanes: can you say that there were not special approval rights granted? there were not special approved rival -- rights granted from the support folks in the donald trump campaign? mr. zuckerberg: yes. when i am saying -- rep. sarbanes: i will take you at your word. the reason this is important and we need to get to the bottom of it, i

zuckerberg. we will hear what the facebook ceo says about data privacy and the future of social media. a lot to come in the next two hours and more, but we are 30 minutes into the wednesday trading session in the u.s., and a lot has happened to roil markets already. good thing julie hyman is here. julie: there is a lot to sift through. you have the paul ryan news, the facebook hearing, the president tweeting about syria. we are seeing stocks pare some of their initial declines, particularly the nasdaq, which is little changed. they spoke shares are higher gain after a 4.5% yesterday. of course, we have seen big swings on a daily basis for the major averages. take a look at the s&p 500 on the bloomberg as one example. here is the daily percentage 1%e of the s&p -- demarcation line. it has really been swinging. overall the s&p is down a little more than 1%. all of these swings are not absolute movement thus far this year. let's look at other asset classes today, because we are seeing some movement

as mark zuckerberg testifies before us lawmakers, we hearfrom as mark zuckerberg testifies before us lawmakers, we hear from the american social media expert known as the queen of facebook, and we talked to a russian dissident who says he has twice been poisoned by the state. what advice would he give spy the state. what advice would he give spy girl as she leaves hospital? that's on newsnight later. —— yuli skripal. —— yulia skripal. good evening and welcome to bbc news. the chief executive of facebook, mark zuckerberg, has apologised to a us senate committee for allowing companies, such as the british data firm cambridge analytica, to misuse personal data. he said that facebook did not take a broad enough view of its responsibility and accepted that russia had exploited the network in the us presidential election. our media editor, amol rajan, reports. it was the interrogation he feared and had long resisted. mark zuckerberg has never testified before congress. now, with the eyes of the world on him, this moment in the spotlight promised high drama and delivered it. in his

fire zuckerberg. so there's no mechanism to remove himself except auto. >> if he thinks it will save his company. >> i used to like napster too. >> all things are up for grabs. what's the one thing you're watching for today? >> i think the onus is on him. even if it might technically be on congress to come up with some remedy. to say we're not just complicit, but to really get into some teeth about what the platform can do to mitigate this threat. if he doesn't do that, i think he'll have a tough day. >> it's going to be an interesting day. cominge ing up, president trump the u.s. has several military options for syria and will act soon. is a strike imminent? plus, an nbc news exclusive. russia has figured out how to jam u.s. drones in syria. those details next. [burke] at farmers, we've seen almost everything so we know how to cover almost anything. even "close claws." [driver] so, we took your shortcut, which was a bad idea.

it's been a long two days for mark zuckerberg. still the facebook ceo emerged mostly unruffled after 48 hours of congressional grilling. zuckerberg generally kept his cool, even as lawmakers downplayed his apologies over failures to protect user privacy and assurances to do better. some key takeaways, regulatory proposals are coming, but there is no clear agreement on what regulations will look like or what facebook would support. still, shareholders and seem to be relieved that zuckerberg can hold his own in testimony. shares rose through both days of the hearing. data collection, particularly off facebook for those who were not on facebook, emerged as a key concern. joining us now to dissect of the , our48 hours in washington guests who have been following every step of these hearings. my take away from day two, more pointed questions, better informed questions. zuckerberg still generally unflustered, but a little more evasive and a little more nervous. david: they were really attacking him and trying hard to sort of bait him to

zuckerberg, along with his wife, established the chan-zuckerberg initiative for further philanthropic causes i turn to you. welcome to the committee whatever your statement is orally, if you have a longer one, it'll be included in the record so proceed, sir. >> chairman grassley, chairman thune, ranking member nelson, and members of the committee, we face a number of important issues around privacy, safety, and democracy. you will rightfully have hard questions for me to answer before i talk about the steps we're taking to address them, i want to talk about how we got here facebook is an idealistic and optimistic company for most of our existence, we focused on all of the good that connecting people can do as facebook asgrown, people everywhere have gotten a powerful new tool for staying connected to the people they love, for making their voices heard, and for building communities and businesses just recently, we've seen the me too movement and the march for our lives organized at least in part on facebook after hurricane harvey, people came together to raise more than $20 million for

zuckerberg parried back. they were unable to press mark zuckerberg or get into the depth. it is not zuckerberg's job to clean up the mess, but it is also congress's job to pass laws, and provide strong protection for the american public. there was not sufficient commitment or discussion about what an internet bill of rights would look like. emily: what should congress do? ro: i think that there is some very common sense things that we should do. you ought to have a right to know your data. if you want to know your financial information, you can go get your credit report. you can know who has asked for that credit information, who is trying to get information about you. you should have the ability to do that with all of your data. you should be able to inquire facebook, twitter, google, or cambridge analytica to give you a report of your data. we have these rights for health also. second, you should be able to update your data. third, you should be able to move, and delete your data. europe has a comprehensive set of these rights. i think the european regulation goes too fa

zuckerberg, i think your cozy community, as dr. martin jamieson recently said, is beginning to look a lot like "the truman show," where people's identities and relationships are made available to people who they don't know. >> your platform is still being used to circumvent the law and allow people to buy highly addictive drugs without a prescription. with all due respect, facebook is enabling an illegal activity, and in so doing, you are hurting people. >> you said everyone controls their data, but you are collecting data on people that are not facebook users, and you are collecting their data. emily: so where does the social network go from here? we posed that question to roger mcnamee, and our very own sarah frier. >> so all those times during that 10 hours of testimony that zuckerberg said, i will have my team follow up with you on that, now that is happening. the congressmen are getting their questions to facebook staff, facebook staff has to go through and meticulously answer them all, then we will get some him really interes

mark zuckerberg on capitol hill. leonard: i asked him a direct question and he responded. i tend to disagree with his response. the ftc is now investigating the matter and i hope the investigation occurs in a timely fashion. emily: what are you most concerned about? leonard: i'm concerned about the privacy of the american people and certainly the privacy of the american people was violated in this situation. moving forward, we have to make sure that it does not happen again. emily: do you think that regulation -- more regulation is necessary? leonard: i am a cosponsor of a bill sponsored by marsha blackburn of tennessee, the browser though -- bill. ist would have a system that more protective of the privacy of the american people, and you have to opt in. the browser bill is for all isp's and i think that is the way to proceed. emily: is there any regulation beyond that that you would support, given that there are a ride range of topics -- wide range of topics here? leonard: i want to make sure that companies have the

zuckerberg a quick break here >> i'm melissa lee, you are joining us of special coverage of mark zuckerberg's testimony it began 2:30 p.m. eastern time. investors appeared to have like what they saw, shares jumped 2.5% facebook has had its best day. "fast money" time is here. all here for instant reaction. and jim cramer will be joining us in a few minutes. julia, what was the most interesting thing you heard today? how would you grade him? >> i think he is doing well. he hasn't broken a sweat and he has been grilled by the 43 senators who are in the room still probably almost an hour left of questions yet to come. and fielding questions on a wide range of topics, everything from election manipulation to data security, to cracking down on hate speed and even social media addiction. an assortment of questions and a number of questions about regulations. he said he was open to regulations. and also asked about the sustainability of facebook's business model here is what he said >> is an alternative to facebook in the private sector? >> yes, the average american uses eight different apps to comm

zuckerberg, good afternoon. let me just cut to the chase, if you and other social media companies do not get your act in order, none of us are going to have any privacy anymore. that's what we're facing. we're talking about personally identifiable information that if not kept by the social media companies from theft, a value that we have in america being our personal privacy, we won't have it anymore. by the advent of technology and of course all of us are part of it. from the moment we wake up in the morning until we go to bed, we're on those hand held tablets. and online companies like facebook are tracking our activities and collecting information. facebook has a responsibility to protect this personal information. personal information. we had a good discussion yesterday. we went over all of this. you told me that the company had failed to do so. it's not the first time that facebook has mishandled it users' information. the ftc found that facebook's privacy policies had deceived users in the past. and in the

zuckerberg. the only regulation that was since thented -- commit millions of rules have been created in response to an abuse of freedom. oftentimes, that response is more extreme than that abuse. that's what i fear could happen. this national discussion is very important. not only for the last two days, but that it continues -- west we over respond. andconsumer and industry whatever industry it is sure that response ability. -- h-share that responsibility that is hostility. hare that responsibility. his answers are very reassuring to me -- i'm wondering what your answer would be to how quickly you would come down on an illegal drug site -- give it your best. don't wait for somebody to flag it. look for it. make it a 30. -- make it a priority. letter -- be better than this. mr. zuckerberg: i miscommunicated if i left the goingsion that we weren't after tools to fight this content and were only relying on people to flag it for us. -- at only focus on ads lot of people share this stuff in groups, to

zuckerberg. i think that gets to the heart of this expectation gap with users. you are logged in in a separate browser and log into another article, open a new tabs in the browser with your facebook cap open, the new button, you track the article you are reading, is that correct? i think there is functionality like that, yes. senator: do you think users understand that? mr. zuckerberg: senator, i think there is a reasonable -- i think the answer is probably yes for the following reasons. on awe show a like button website we show social context. it says, here are your friends who like that. in order to do that, we would have to -- have yourut if you facebook browser open and open an article in the denver post with the facebook button on it, do you think consumers, users know, that facebook now knows what article you were reading in the denver post? we would need to have that in order to serve up the like button and show you who your friends were who had also like to that. -- liked that. senator: i

facebook's mark zuckerberg will be testifying. we'll ask a team of experts what we could learn today about the private company that we trust with so much of our information. but we start with new details this afternoon on the justice department raid on the office and residences of trump's personal attorney michael cohen. "the new york times" reporting that fbi agents were looking for recordings abo records about payments to two women who claim they had affairs with mr. trump. this, as news the president is embroiled in new controversy over his reaction to that raid. the president in that extraordinary display last night lashing out at the justice department, the fbi, the special counsel and his attorney general jeff sessions. >> so i just heard that they broke into the office of one of my personal attorneys, good man, and it's a disgraceful situation. it's a total witch hunt. this is the most biased group of people. these people have the biggest conflicts of interest i've ever seen. democrats all -- just about all, either democrat

zuckerberg. thank you very much here i was thinking about facebook and how you develop your platform from a social platform amongst friends and colleagues and joining a community and a lot was based upon trust you knew your friends, right but that evolved into this business platform and one of the pilars still was trust and i think you would all -- i think everyone would agree trust is in short supply here and that's why we're here today. now you've constantly maintained that consumers own the data they provided to facebook and should have control over it and i appreciate that. i just want to understand more about what that means. to me, if you own something, you ought to have say about how and when it's used but to be clear i don't just mean pictures, elon musk addresses, facebook groups or pages i understand the data and information consumers provided to facebook can be and perhaps is used by algorithms to form assumptions and inferences about users to better target ads to the individuals. now,

zuckerberg. you have told us today and have you told the world that facebook was deceived by alexander kogan when he sold user information to cambridge analytica, correct? >> 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 will note that the ftc order specifically requires facebook to protect the privacy. isn't there a conflict there? >> senator, it certainly a

zuckerberg in person on this. i think most people think there was a breach of trust and we need to get to the bottom of how that happened. did that violate the law or their own policies? what needs to be done going forward? >> something investors are trying to get their head around. if you decide from these hearings that facebook's internal controls are not adequate, what does regulation look like from washington, d.c.? what kind of regulations have you got in mind? sen. wicker: i have an open mind about what we need to do. i think that ought to be the approach of most members of the committee. i do not have legislation in mind. i don't think the ftc has regulations in mind. i think we will be listening to what we find out. i will tell you, generally speaking, i come down on the side of a light touch regulation. i think the internet has derived -- thrived. it has been the engine of our economy and economic growth for two and a half, three decades. and we need to be careful with overregulation. at the same time, if
