Facebook hasn't found other companies that leaked data like Cambridge Analytica did, said Facebook COO Sheryl Sandberg in a series of interviews published Thursday.

The statement speaks to a larger concern that many experts have expressed since The New York Times and The Guardian's Observer publication reported that UK-based Cambridge Analytica had improperly received information on millions of Facebook users. On Wednesday, the company said it counted as many as 87 million Facebook profiles that may have been caught up in the widening Cambridge Analytica scandal. Facebook also said it's possible that public information for many of its 2 billion monthly users may also have been collected by other firms.
