Document reveals how Facebook downplayed early Cambridge Analytica concerns

Internal correspondence provides new insight into how Facebook staff reacted to concerns about use of user data by political campaign consultants

Internal Facebook correspondence from September 2015, released as part of a US government lawsuit on Friday, reveals new details about Facebook's early knowledge of potentially improper data collection by Cambridge Analytica.

The existence of the internal discussion was first reported by the Guardian in March 2019. That report marked Facebook's first acknowledgement that some of its employees were aware of concerns about improper data practices by Cambridge Analytica four months before the Guardian's 11 December 2015 article exposed them.
