Facebook revealed on Friday that a voter profiling firm hired by Donald Trump and other Republicans had improperly used data from 270,000 users of the social media platform. Special Counsel Robert S. Mueller III has reportedly requested documents from Cambridge Analytica for its investigation. Facebook’s announcement on Friday focused on how people affiliated with Cambridge Analytica had violated policies of the social media platform. Facebook issued a statement Saturday underscoring that its policies now prevent a repeat of what Kogan and Cambridge Analytica did. Cambridge Analytica specializes in using online data to create voter personality profiles in order to target users with political messages and ran data operations for Donald Trump's presidential campaign.
