After two days and more than 10 hours of questioning of Mark Zuckerberg, the Facebook chief executive, there was widespread consensus among lawmakers that social media technology — and its potential for abuse — had far outpaced Washington and that Congress should step in to close the gap. But the agreement largely ended there.

Facebook CEO Mark Zuckerberg's appearance before Congress turned into something of a pointed gripe session, with both Democratic and Republican senators attacking Facebook for failing to protect users’ data and stop Russian election interference, and raising questions about whether Facebook should be more heavily regulated. Of specific interest were the revelations that sensitive data of as many as 87 million Facebook users were harvested without explicit permission by a political consulting firm, Cambridge Analytica, which was connected to the Trump campaign.
