Facebook CEO Mark Zuckerberg will express contrition for allowing third-party apps to grab the data of its users without their permission and for being “too slow to spot and respond to Russian interference” during the U.S. election, according to his prepared remarks published by the House Energy and Commerce Committee. Zuckerberg plans to open his remarks this week before a joint hearing of the Commerce and Judiciary Committees with a familiar recitation of the social media platform’s ability to link far-flung people together but then pivot into an acknowledgment of Facebook’s increasingly visible dark side. “It’s clear now that we didn’t do enough to prevent these tools from being used for harm as well,” Zuckerberg plans to tell lawmakers.
