Government officials in the US and Europe are demanding answers from Facebook Inc after reports that Cambridge Analytica, the advertising-data firm that helped Donald Trump win the US presidency, retained information on tens of millions of Facebook users without their consent.
Over the weekend, entreaties for the social-media giant to take responsibility evolved into calls for chief executive officer Mark Zuckerberg to appear in front of lawmakers. Facebook has already testified about how its platform was used by Russian propagandists ahead of the 2016 election, but the company never put Zuckerberg himself in the spotlight with government leaders. The pressure may also foreshadow tougher regulation for the social network.
