Mark Zuckerberg will have to give a 6-hour deposition about Cambridge Analytica as part of a class-action lawsuit

• Mark Zuckerberg will give a six-hour deposition on Cambridge Analytica as part of a class-action lawsuit.
• The class action was filed in 2018 on behalf of California Facebook users.

Mark Zuckerberg is going to have to testify about Cambridge Analytica again.

A class-action lawsuit filed on behalf of California Facebook users is calling Zuckerberg for a six-hour deposition in September, according to a court filing submitted Wednesday and viewed by Insider.

The Cambridge Analytica scandal first made headlines in 2018 when news reports revealed a British data analytics firm called Cambridge Analytica had harvested the data of millions of Facebook users without their consent.

The company has tried to salvage its reputation since 2018. In October 2021, it changed its name to Meta but Cambridge Analytica continues to haunt it.

The lawsuit, which was first filed in 2018, is also calling Meta's COO Sheryl Sandberg for a five-hour deposition.

Sandberg announced in June she is stepping down from her role at Meta. She will be replaced by Javier Olivan, who has also been summoned for deposition.

The filing stated prosecutors plan to depose other Facebook executives, who are "key witnesses," for more than seven hours.

The filing also said Facebook will hand over 1,200 documents to prosecutors that the company previously withheld as privileged.

This isn't the first time Zuckerberg has been called to testify over Cambridge Analytica. The Facebook founder appeared before a US Senate joint committee hearing in 2018 to give evidence on how the company handled user data in the wake of the scandal.

The Cambridge Analytica breach resulted in a record-breaking $5 billion fine for Facebook from the Federal Trade Commission in 2019, and severely damaged the tech giant's reputation around user privacy.

Meta did not immediately respond when contacted for comment by Insider outside of normal working hours.
