we didn't take a broad enough view of our responsibility and that was a big mistake and it was my mistake and I'm sorry I started Facebook I run it and I'm responsible for what happens here mr. Zuckerberg would you be comfortable sharing with us the name of the hotel you stayed in last night know if you've messaged anybody this week would you share with us the names of the people you've messaged a senator no I would probably not choose to do that publicly here I think that maybe what this is all about your right to privacy the limits of your right to privacy and how much you give away in modern America in the name of quote connecting people around the world who's your biggest competitor senator we have a lot of competitors who's your biggest the other tech platforms so Google Apple Amazon Microsoft we overlap with them in different ways isn't an alternative to Facebook in the private sector yes senator the average American uses 8 different apps ok communicate with their friends and stay in touch with people ranging from tablet apps to email service you provide well we do provide a number of differences clitter the same as what you do it overlaps with a port you don't think you have a monopoly all right certainly doesn't feel like that to me ok which are you are you a tech company or you the world's largest publisher do we feel a responsibility for the content on our platform the answer to that I think is clearly yes and but I don't think that that's incompatible with fundamentally yet at our core being a technology company where the main thing that we do is have engineers and build products have you ever drawn the line on selling data to an advertiser it's actually one of the most important parts of how Facebook works is we do not sell data advertisers do not get access to people's individual data have you ever collected the content of phone calls or messages through any Facebook application or service senator I don't believe we've ever collected the content of phone calls we have an app called messenger that allows people to message their mostly their Facebook friends did you or senior leadership do an inquiry to find out who at Facebook had this information and did they not have a discussion about whether or not the users should be informed back in December of 2015 senator in retrospect I think we clearly view it as a mistake that we didn't inform people and we did that based on false information that we thought that the case was closed and that the data had been deleted so there was a decision made on that basis not to inform the users is that correct that's my understanding yes do you know when that Congress when that decision was made not to inform the users I don't how much revenue did Facebook earn from the user engagement that resulted from foreign propaganda well senator what we do know is that the IRA the internet research agency the the Russian firm ran about a hundred thousand dollars worth of ads I can't say that we've identified all of the foreign actors who are involved here so I I can't say that that's all of the money but that is what we have identified okay mr. Zuckerberg I come in peace I don't want to vote to have to regulate Facebook but my god I will but that a lot of that depends on you and I say this in gently your User Agreement sucks the purpose that User Agreement is to cover Facebook's rear end it's not to inform your users about their rights now you know that and I know that are you willing to go back and and work on on giving me a greater right to erase my data senator you can already delete any of the data that's there or we don't need to expand that work on expanding that senator I think we already do what you're referring to but certainly we're always working on trying to make these controls easier are you willing to expand my right to know who you're sharing my data with senator we already give you a list of apps that that you're using and you signed into those yourself and provided affirmative consent right as I've said before I don't share any datum that User Agreement are you willing to expand my right to prohibit you from sharing my dad senator again I believe that you already have that control so I mean I think people have that that full control in the system already today if we're not communicating this clearly then that's a big thing that we should work on I assume Facebook's been served as subpoenas for the special counselor's office is that correct yes if you were anyone at Facebook but interviewed by the special counsels office yes have you been interviewed I have not I have not others have I believe so and I want to be careful here because that our work with the special counsel is confidential and I want to make sure that in an open session I'm not revealing something that's confidential
