<https://www.washingtonpost.com/news/the-switch/wp/2018/03/16/facebook-bans-t...> Facebook is suspending the Trump-affiliated data analytics firm Cambridge Analytica, after learning that it failed to delete data that it had taken inappropriately from users of the social network, Facebook said late Friday. Facebook said it was suspending the accounts of Strategic Communication Laboratories, the parent company of Cambridge Analytica, as well as the accounts of University of Cambridge psychologist Aleksandr Kogan and Christopher Wylie of Eunoia Technologies. Cambridge Analytica, a firm that specializes in using online data to create voter personality profiles in order to target users with political messages, ran data operations for Donald Trump's presidential campaign. The company was funded by Trump supporter and hedge fund billionaire Robert Mercer, and the president's former senior adviser Stephen K. Bannon once sat on its board. The company, which began working for the Trump campaign in June 2016, promised that its so-called "psychographic" profiles could predict the personality and political leanings of every adult in the United States.
