PolygamousRanchKid shares a report from CNN: Cambridge Analytica whistleblower Christopher Wylie says the data the firm gathered from Facebook could have come from more than 87 million users and could be stored in Russia. Wylie added that his lawyer has been contacted by U.S. authorities, including congressional investigators and the Department of Justice, and says he plans to cooperate with them. Aleksander Kogan, a Russian data scientist who gave lectures at St. Petersburg State University, gathered Facebook data from millions of Americans. He then sold it to Cambridge Analytica, which worked with President Donald Trump's 2016 presidential campaign. "I know that Facebook is now starting to take steps to rectify that and start to find out who had access to it and where it could have gone, but ultimately it's not watertight to say that, you know, we can ensure that all the data is gone forever," he said.
