Facebook’s Mark Zuckerberg Named in Suit by Washington, D.C., Attorney General.

The District of Columbia’s attorney general is seeking to hold FacebookInc. Chief Executive Mark Zuckerberg personally liable in a lawsuit stemming from the 2018 Cambridge Analytica scandal, in what the district said was a novel legal action against the social-media giant.

Attorney General Karl Racine said Wednesday he filed a motion to add Mr. Zuckerberg as a defendant in a consumer-protection lawsuit originally filed in December 2018 accusing Facebook of misleading its users about the privacy and security of their personal data. His office said it was the first time a U.S. regulator has specifically named Mr. Zuckerberg in a complaint.

Facebook spokesman Andy Stone said the “allegations are as meritless today as they were more than three years ago, when the District filed its complaint.

“We will continue to defend ourselves vigorously and focus on the facts,” he said.
