mr. wylie: yes. senator cornyn: mr. zuckerberg when he was here the other day, he kept saying, we don't sell data. and i responded to him, well, rent it.ly rent it. i don't know if that's a fair characterization or no. how would you characterize the social media platforms like facebook use of personal data? they say they don't sell it. how would you characterize it? mr. wylie: they have create add platform that -- created a platform that encourages the use of data. so it's true that you can't go to facebook and simply buy facebook data. but they make it readily available to its customer via its network of applications or the fact that the lateout of people's profiles on facebook makes it very conducive to scraping data, for example. although facebook would say they don't allow that, they still setup which catalyzes its misuse in my view. senator cornyn: mr. zuckerberg also said the terms of service that consumers agree to when they sign on to facebook, you said people probably don't read it. or if they read it did he th

mr. wylie. i think these will be easy questions, but listen while i lead up to them. you joined cambridge analytica group companies in june of 2013, in may of 2014 the group received facebook data from aleksandr kogan. you stopped working for the group in july 2014. in early 2016, facebook contacted the group and yourself and asked that facebook data received from mr. kogan be deleted. in march of 2017 following an internal audit, the group certified it had purged all of mr. kogan's facebook data from its servers. the group was retained by the trump campaign in the summer of 2016, so i think these three questions will be easy. cambridge had not been retained by the trump campaign during your employment? mr. wylie: when i worked at cambridge analytica, the trump campaign was not, no. sen. grassley: and you did not work for the trump campaign while at cambridge? mr. wylie: i have never worked for the trump campaign. sen. grassley: and you were not there with the company made its certification to
