. >> cnn's laurie segall joins me now. laurie, terrific, compelling interview. well done. we saw contrition there. i think the question this morning is exactly what was the contrition for. >> reporter: look, i think it's been a really rough year for facebook, and i think in the last week this has been a crisis for the company. i actually asked mark, i said we look at this company -- in the last year, we look at the weaponization of the platform for political gain, and can we trust that you guys are making sure we are protected as we go into the midterm elections and looking back, did you do enough? take a listen. >> i think what's clear is that in 2016 we were not as on top of a number of issues as we should have been, whether it was russian interference or fake news. this isn't rocket science. there's a lot of hard work that we need to do to make it harder for nation states like russia to do election interference, to make it so that trolls and other folks can't spread fake news. but we can get in front of this. >> do you think that bad actors are using facebook at this mo

cambridge analytica, facebook as well and the name synonymous with facebook, mark zuckerberg, laurie segall spoke with him and we want to directed our viewers to check that out on cnn.com, but the question to you, what have authorities said about him, what do they want to know about him and whether he might have to testify there? >> reporter: well, on this side of the pond as you well know, people called investigators, lawmakers calling for cambridge analytica as well as zuckerberg to testify in terms of what he knew and how much of that information was passed on to the professor at cambridge university who created this app. but lawmakers here don't feel that his apology with that interview that you mentioned there with laurie segall, whether that went far enough. and there are several reasons for that. one is that he didn't answer critical questions which really are along the lines of he knew about this back in 2015. why didn't you do something about it then. have you spoken -- have you you contacted the 50 million people that have been -- whose data is being passed on. and also, you know,

laurie segall here with more. >> a lot of people want to hear from mark. the public, want to hear from mark. i thought it was interesting from talking to sources inside, he's very involved behind the scenes, a well respected leader. but this is a moment of crisis for facebook. executives at the top level are saying we want him out in front of this. we don't want other people taking the punch for a lot of this. another thing that was really interesting that executives said to me is the challenges and the conversations happening behind closed doors at facebook about our future, these conversations about howe they deal with fake news, our data, privacy, russian influence. they're very nuanced conversations. people say it's really hard to have those conversations publicly, but executives are pushing because they say it's important to have these nuanced conversations publicly. someone said to me there are legitimate tradeoffs. if we crack down on fake news, it could potentially -- we look at censorship with data privacy, this will impact developers. i think the

in an exclusive interview with laurie segal, he said facebook will investigate all apps with access toser data. >> it is hard to know what we will find. we're going to review thousands of apps. so this is an intensive process. this is important. this is something we clearly should have done up front with cambridge analytica. we should not have trusted the certification they gave us. we are not going to make that mistake again. >> zuckerberg also believes bad actors are still trying to use facebook to influence the mid-term elections. he acknowledges he never thought this would be something he would be dealing with ever. >> if you told me in 2004 when i started facebook that part of my responsibility is to help protect the integrity of the elections of other interference of governments, i would not believe that would be something i have to work on 14 years later. we are here now. we're going to make sure we do a good job of it. >> have you done a good enough job yet? >> well, i think we will see. you know, what's clear in 2016 we were not as on top of the issues we should have been. >>

the ceo mark zuckerberg speaking to laurie segall let's listen and we'll discuss. >> there is hard worko do to make it harder for nation states like russia to do election interference, make it so that trolls and other folks can't spread fake news. but we can get in front of this. and we have a responsibility to do this not only for the 2018 mid-terms in the u.s. which are a huge deal this year. and that's just a huge focus of us. but there is a big election in india this year. and in brazil. big elections around the world. and you can bet that we are really committed to doing everything that we need to to make sure that the integrity of those elections on facebook is secured. >> brian stelter, what stood out to you in zuckerberg's comments. >> he is looking to the future thinking about how to avoid some of the embarrassments of the past. in scandal that's consumed almost a week is about data from 2014 that might have been misused in the 2016 presidential election. but we're now close to mid-terms. people are thinking about 2020. as zuckerberg it's not just about the u.s. but countries a

our colleague laurie segall is about to sit down with zuckerberg in enlo park, a big interview on "ac 360." we've not heard from zuckerberg in a while about any topic. it's rare to see him on television. i think it shows how seriously he's taking this, that he wants to sit down and talk more about it. this does leave a lot of questions still unanswered. >> dillon, what do you think? >> just the sheer length of that statement alone, and all the different steps that zuckerberg had to outline in terms of what they're going to do to try to protect user data highlights something, which i think is really important and is the key issue with this entire scandal. user data and the exploitation of user data selling that to third parties who can then use it for -- you know, to boost their own brands or their own political candidates, that is caked in to facebook. that is what facebook does. what mark zuckerberg is trying to do now, amid all this public pressure, he is trying to limit how much that data can be exploited while still keeping pacebook intact. if you don't have data to sell to third
