Former Facebook product manager Frances Haugen appeared before a U.S. Senate subcommittee, testifying that the company’s products “harm children, stoke division and weaken our democracy,” and implored Congress to take action. (The Logic)

Talking point: Haugen’s testimony could be the catalyst for tougher U.S. regulations of tech companies. It comes after Haugen went public on “60 Minutes” on Sunday as a corporate whistleblower after being the source for a series of reports in The Wall Street Journal about issues at Facebook. She told the subcommittee today that understaffing is part of the problem. Haugen raised national-security and human-rights concerns about Facebook’s platforms. A statement issued to various media outlets by Lena Pietsch, Facebook’s director of policy communications, downplayed Haugen’s role at the company and questioned the depth of her knowledge on internal matters. Meanwhile, Facebook released more details about Monday’s outage, saying it was caused by a malfunctioning command intended to assess its data network capacity.
