tell viewers about who was on capitol hill and why they were there? guest: sheryl sandberg, the chief operating officer of race book testified on election security and the use of platforms by foreign adversaries in the u.s. election process. she was joined by the ceo of twitter, jack dorsey. jack then travel to the other side of capitol hill to the house for the energy and commerce committee where he testified so low on the idea that twitter may be biased. host: what is the significance that you had the ceos of these platforms to talk about these issues? guest: it has been a long time coming. the companies are in the spotlight for they didn't do enough in the election by russia. in their own definition they were slow to take action in that. a lot of their testimony was acknowledging they were slow to act. so it is significant to have them with push and pull. jack dorsey's first testimony and he has been the ceo for quite some time. so to have him up there answering questions was significant. google was also invited. the decline to send a representative. which lawmakers did not enjoy. host: what did they resolve to do because of that? is a rolling process by their own admission. one of the things they have done is to hire humans and work on technology to determine fraudulent accounts. i have figured out ways to detect signs that accounts are not coming from people they want to have on the platform and thwarting them when they try to register to use the platform. they put a lot of attention into that. and they have also done more for transparency. one of the complaints was that ads would be placed on the sites pay for theng who add. those are additional steps they've taken. they have resisted the idea of having regulation around that sort of transparency but they are eager to take those steps voluntarily. so they don't have to be regulated. what is their thinking on that currently? guest: we are in a push and pull phase that washington goes through. police yourself or we will step in. and we are seeing conservatives theyepublicans say that will not take a hands-off approach. host: calling in to join us on of discussion on the ceos facebook and twitter. if you would like to ask a ,uestion, it is (202) 748-8000 democrats.

guest: i think so. it was only jack dorsey testified alone. i think he handled himself well. and members seemed pretty responsive to him personally. think he has proven that he has no intention of discriminating godless of what personal ideology would be -- informationng regardless of what his personal ideology would be. some said that it would not spare -- that it was not fair for him to be there without other platforms. the committee argued that twitter has become such a platform -- the first argument is that we are open to having all the companies guest: shadowing is a term, an umbrella term for the idea some of the decisions made about how the platform, interactive features of the platform, just to take a step back, there is so much content on twitter they can't throw everything at everyone. they do make decisions how to rank and promote content. their argument is in making some of those decisions, that search functionality feature, that it makes it harder to find accounts, shadow banning includes that. also the idea if you click on a hash tag, a key word that appears on twitter, that groups conversations on a common theme, in some cases that appears in that conversation. their argument is we have to manage that content in some wafmente conservatives in particular embrace this idea of shadow banning, we don't know you can't -- i can't know you are not seeing my tweets. in some way i'm hidden on the platform. ---202-p 48-8001. it was during that hearing where jack dorsey had exchange about these shadow accounts with the chairman, greg walden. here's a bit of that exchange. mr. walden: certain prominent serve serve users, including of sour colleagues, who have come to us, representative meadows, jordan, gaets, were not shown in the automatically populated dropdown searches on twitter, correct? out of the more than 300 million active twitter users, why did this only happen to certain accounts? in other words, what did the algorithm take into account that led to prominent conservatives, including members of the u.s. house of representatives, not being included in auto search suggestions? what cows causted that mr. dorsey: thank you for the question. we used signals. usually hundreds of signals to determine and decide what to show, what to down rank, or potentially what to filter. in this particular case, as i mentioned in my opening, we were using a signal of the behavior of the people following accounts. we didn't believe upon further consideration, and also seeing the impact, which was about 600,000 accounts, pretty broad pace based, that was fair and we decided to correct t we decided it was not fair to use a signal for filtering in general. we decided to crack that within search as well -- correct that within search as well. it is important for us to, one, be able to experiment freely with the signals, and to have the freedom to be able to inject them and also to remove them, because that's the only way we're going to learn. we will make mistakes along the way, and the way we want to be judged is making sure that we recognize those and that we crack them. host: not only talk about his response but his style in approaching the legislators and how that compares and contrast with miss sandberg. guest: very deliberate. very thoughtful. i mentioned before we got on air he had come by the "politico" world headquarters in rosalyn, virginia, for an interview and sat down with our editorial team before his testimony. the response seems to me he approaches -- he's certainly thought about these issues. so he presents himself in that way. he speaks very deliberately. i think there's been some commentary, fair or not about his appearance. he has a fairly described as scraggly beard. i don't know what a viewer on twitter should look like, but it's not that. and he said yes, i agree with you. but as i mentioned i think he handled himself in way that was very much him but also in way that was appropriately from the members of congress point of view deferential and respectful. host: quite a different world for them. they probably have staffers that handle particularly pieces of legislation or what happens on capitol hill directly. guest: in the past it has been a little bit -- it's interesting the ways the different tech companies approach washington. some have their headquarters in california. speaker ryan: i don't know how any were around in the 1960's. that's the last time the number of americans filing for unemployment benefits was this low. 49 years ago. it this is the best job market we have had in decades. and here's something else that's very encouraging. workers in what are traditionally considered lower-wage jobs, the bank tellers, maintenance workers, they are seeing some of the gg
