Facebook is admitting that as many as 87 million people might have had their data accessed, an increase from the 50 million disclosed in published reports. On Wednesday, CEO Mark Zuckerberg admitted he made a "huge mistake" in failing to take a broad enough view of what Facebook's responsibility is in the world.

MARK ZUCKERBERG CEO, FACEBOOK "But it's clear now that we didn't do enough. We didn't focus enough on preventing abuse and thinking through how people could use these tools to do harm as well. And that goes for fake news, foreign interference in elections, hate speech, in addition to developers and data privacy. We didn't take a broad enough view of what our responsibility is, and that was a huge mistake. It was my mistake."

Congressional officials said Zuckerberg will testify next week. Meanwhile, Facebook unveiled a new privacy policy that aims to explain the data it gathers on users more clearly. The social media giant is facing its worst privacy scandal in years following allegations that Cambridge Analytica, a Trump-affiliated data mining firm, used ill-gotten data from millions of users to try to influence elections. Facebook is restricting access for apps trying to obtain user data, such as the events they go to, or member lists and content in groups. In addition, the company is also removing the option to search for users by entering a phone number or an email address.
