Frances Haugen, a Facebook whistleblower whose revelations have pitched the social network into its biggest crisis since the Cambridge Analytica furore, will make her first appearance before US senators in Washington on Tuesday.
The hearing comes after she unmasked herself on US television on Sunday night as the source who provided thousands of pages of internal documents to the Wall Street Journal that revealed frequent inconsistencies between Facebook’s public statements and its private research.
Haugen said the documents show the Silicon Valley company repeatedly prioritised “profit over safety”. She has also filed complaints to the US Securities and Exchange Commission over whether Facebook misled investors.
