Aleksandr Kogan, the data scientist at the center of the Facebook data scandal, said Mark Zuckerberg is "totally" a hypocrite.

In March, The New York Times and The Guardian reported that political data-research firm Cambridge Analytica improperly got ahold of data of as many as 87 million Facebook users on the social media platform. The information was collected through a quiz app created by Aleksander Kogan, a researcher who worked at Cambridge University at the time, then passed to the political research firm.
