WASHINGTON — Facebook on Wednesday said the personal information of up to 87 million people, most of them Americans, may have been improperly shared during the 2016 election with Cambridge Analytica, a political consulting firm connected to President Trump.
The new figure sharply increased the company’s previous estimate of how many users’ information was harvested by Cambridge Analytica. For weeks, Facebook had said that the data of about 50 million users was at issue.
Facebook released the revised estimate of affected users as part of an extended statement about its plans for handling personal data. The company said it would start alerting users on April 9 about whether their information may have been shared with Cambridge Analytica.
