Facebook shares plunge amid Cambridge Analytica data falloutFacebook plunged to its worst loss in four years on Monday and led a rout in technology companies. The social media company's stock fell following reports that a data mining firm working for the Trump campaign improperly obtained data on 50 million Facebook users. The drop in Facebook stock came after the New York Times and the Guardian reported that the firm, Cambridge Analytica, was able to tap the profiles of more than 50 million Facebook users without their permission. Facebook said late on Friday that it suspended Cambridge Analytica and its parent company. Facebook also said it recently received a report that Cambridge Analytica hadn't deleted all of the data it obtained from Facebook, something Facebook said the company claimed to have done.
