The FBI, SEC and Justice Department Now Want to Know What Facebook Knew About Cambridge Analytica

A federal probe into Facebook's sharing of user data with Cambridge Analytica now involves the FBI, the Securities and Exchange Commission and the Justice Department, the Washington Post reported. Representatives from these agencies have joined the Federal Trade Commission in the inquiry, the newspaper reported, citing five unnamed people familiar with the matter. Those people spoke on condition of anonymity because the probes are not complete. The probe reportedly centers on what Facebook knew in 2015, when it learned that the political data-mining firm Cambridge Analytica had improperly accessed the personal data of tens of millions of Facebook users. Facebook didn't disclose the incident with the political firm, which later worked for the Trump campaign and other Republican candidates, until this March.
