Facebook told CNN it is looking into ties between one of its current employees and Cambridge Analytica, the controversial data firm that worked for Donald Trump's presidential campaign and was suspended by Facebook on Friday.
Joseph Chancellor, now a researcher at Facebook, was a director of Global Science Research, a company that provided data to Cambridge Analytica. The New York Times and The Observer newspaper in London reported Saturday that Cambridge Analytica harvested information on 50 million Facebook users.
The revelations have prompted renewed scrutiny of how Facebook was used to reach and influence voters ahead of the 2016 US presidential election.
"Joseph Chancellor is an employee of Facebook. We are looking into the situation," a spokesperson for Facebook told CNN.
On Friday, Facebook announced it was suspending Cambridge Analytica and data scientist Aleksandr Kogan, Chancellor's former business colleague, from using its platform while it investigates.
Facebook said in a blog post that Kogan "lied to us" and "violated" its policies in 2015 "by passing data" to a third party, including Cambridge Analytica.
The nature of Chancellor's role as a director of Global Science Research and his knowledge of Kogan's data collection practices are not clear. A spokesperson for Cambridge Analytica said "there was no recollection of any interactions or emails with" Chancellor.
Facebook didn't mention Global Science Research in its blog post. But Cambridge Analytica said Saturday that it contracted the company in 2014 to "undertake a large scale research project in the United States."
Global Science Research was incorporated in May 2014 and listed Kogan and Chancellor as directors, according to UK government records. (The records show that Global Science Research was dissolved in October 2017.)
Neither Kogan nor Chancellor have responded to CNN's requests for comment through email and social media. In addition, Facebook has not replied to a request that it ask Chancellor for comment.
On his work profile, Chancellor describes himself as a quantitative social psychologist.
Kogan and Chancellor were both at the University of Cambridge when they set up Global Science Research, according to their LinkedIn profiles.
The UK government records show Chancellor left Global Science Research in September 2015. According to his LinkedIn profile, he joined Facebook in November 2015.
A spokesperson for Cambridge University told CNN that Kogan, who still works for the university, assured them "that none of the data from his academic research was transferred for commercial use." Cambridge University could not immediately say if it asked Chancellor for similar assurances.
The data on Facebook users was gathered through a survey app called "thisisyourdigitallife." According to the Cambridge University spokesperson, the app was developed by Global Science Research.
The Cambridge spokesperson said Kogan told the university that the app made clear it was for commercial, and not academic, research.
But Facebook disputes that point. Facebook provided CNN with the description it said Kogan gave them about the app in 2014.
"This app is part of a research program in the Department of Psychology at the University of Cambridge," the description stated. "We are using this app for research purposes - learning about how people's Facebook behaviour can be used to better understand their psychological traits, well-being, health, etc and overcome classic problems in social science. Users of the app will be presented with a description of the types of data we gather and the scientific purpose of the data."
The description continued, "Users will be informed that the data will be carefully protected and never used for commercial purposes."
While Kogan's collection of the data complied with Facebook policy, how he allegedly shared the data was not. Facebook said it ordered Kogan and Cambridge Analytica to delete the data when it determined Kogan had breached its policies in 2015.
Facebook would not say if Chancellor also had access to the data and if he was asked to delete it.
