Facebook data scandal wider than first reported

NEW YORK (AP) — Face-book revealed Wednesday that tens of millions more people might have been exposed in the Cambridge Analytica privacy scandal than previously thought and said it will restrict the user data that outsiders can access.

Those developments came as congressional officials said CEO Mark Zuckerberg will testify next week, while Facebook unveiled a new privacy policy that aims to explain the data it gathers on users more clearly — but doesn’t actually change what it collects and shares.

In a call with reporters Wednesday, Zuckerberg acknowledged he made a “huge mistake” in failing to take a broad enough view of what Facebook’s responsibility is in the world. He said it isn’t enough for Facebook to believe app developers when they say they follow the rules. He says Facebook has to ensure they do.
