Live Updates: Facebook whistleblower Frances Haugen testifies before Senate committee

Frances Haugen, the Facebook whistleblower who revealed her identity on "60 Minutes" on Sunday night, is testifying before the Senate Tuesday. She said the platform's decisions are "a huge problem" for children, public safety and democracy.

Her testimony comes after she told "60 Minutes" that "there were conflicts of interest between what was good for the public and what was good for Facebook" and Facebook "chose to optimize for its own interests, like making more money."

Haugen worked as a product manager for the civic misinformation team at Facebook for nearly two years before she quit in May. Before leaving, she said she secretly copied tens of thousands of pages of Facebook internal research, which she said provides evidence the company has been lying to the public about making significant progress against hate, violence and misinformation.
