Facing his second day of questioning from members of Congress on Wednesday, Zuckerberg was answering a question from Rep. Anna Eshoo, a Democrat from California.
Facebook has said that 87 million people's personal data was scooped up when some 270,000 users took a personality quiz and had not just their data, but the data of their friends to be accessed by an outside app. Cambridge Analytica then obtained this data and is said to have used it to try to influence elections around the world.
