The whistle-blower whose revelations about Facebook have set off shock waves from Silicon Valley to Washington stepped into the spotlight this weekend.

Frances Haugen, a former Facebook product manager, revealed her identity Sunday on 60 Minutes as the person who leaked tens of thousands of internal research documents to lawmakers, regulators and the media. She said they showed the social media giant was concealing information about its risks to users, and about its progress in combating hate and misinformation.
