Cambridge Analytica whistleblower thinks Facebook data breach affected more users than reported

The Facebook crisis involving Cambridge Analytica's data breach leads many to question how Facebook treats their users' data; Reaction on'Outnumbered.' The man who revealed the Cambridge Analytica data-harvesting scandal said Sunday he believed the political consulting firm snatched information from more than the previously reported 87 million Facebook users. "I think that there is, you know, a genuine -- a genuine risk that this data has been accessed by quite a few people. And that it could be stored in various parts of the world, including Russia, given the fact that, you know, the professor who was managing the data harvesting process was going back and forward between the U.K. and to Russia," Christopher Wylie said on NBC News' "Meet the Press." Wylie was referring to Aleksandr Kogan, whose company, Global Science Research, harvested Facebook's data using a personality app, according to officials.
