Sen. Al Franken (D-Minn.) on Wednesday called on Apple to more fully explain how the facial-recognition system on its new iPhone X will protect the privacy of its users and whether the data will be shared with law enforcement.

The request, in a letter sent to Apple chief executive Tim Cook, echoes concerns that privacy advocates raised following the announcement of the new system on Tuesday. The technology uses several sensors to map the faces of users and stores the resulting data on the device itself, allowing users to later unlock the device or use the Apple Pay app my merely glancing at it.
