Former Facebook employee-turned-whistleblower whistleblower Frances Haugen, who testified before Congress about how the social media giant misled the public, will now face questions in the UK Parliament.
Haugen is set to testify staring at 9:30 a.m. ET.
Haugen, the 37-year-old former Facebook (FB) product manager who worked on civic integrity issues at the company, revealed her identity during a "60 Minutes" segment that aired earlier this month.
She has reportedly filed at least eight whistleblower complaints with the Securities and Exchange Commission alleging that the company is hiding research about its shortcomings from investors and the public. She also shared the documents with regulators and the Wall Street Journal, which published a multi-part investigation showing that Facebook was aware of problems with its apps.
In her testimony before Congress earlier this month, Haugen faced questions from a Commerce subcommittee about what Facebook-owned Instagram knew about its effects on young users, among other issues.
"I am here today because I believe that Facebook's products harm children, stoke division, and weaken our democracy," she said during her opening remarks. "The company's leadership knows how to make Facebook and Instagram safer but won't make the necessary changes because they have put their astronomical profits before people. Congressional action is needed. They won't solve this crisis without your help."
