SEC Probing Whether Facebook Warned Investors About Data Sharing

Securities regulators are investigating whether Facebook Inc. adequately warned investors that developers and other third parties may have obtained users’ data without their permission or in violation of Facebook policies, people familiar with the matter said. The Securities and Exchange Commission’s probe of the social-media company, first reported in early July, follows revelations that Cambridge Analytica, a data-analytics firm that had ties to President Donald Trump’s 2016 campaign, got access to information on millions of Facebook users.
