Yes, but let me clarify. There is a separate Facebook-related incident that has not been reported at all yet—I'm working with a journalist right now to bring it to everyone's attention—that is not involved with Cambridge Analytica, as far as I know, but the number is 48 million people on that one. It does involve messages. The degree of privateness they were sent...is not quite determined yet, but they do get pretty personal.
On April 17th, 2018. See this statement in context.
