The attorney general for Washington, D.C. filed a lawsuit against Meta (FB) CEO Mark Zuckerberg on Monday, accusing him of being personally responsible for the massive Cambridge Analytica data breach.

In the suit, Attorney General Karl Racine, alleges that Zuckerberg's failure to oversee consumers' data privacy led to the Cambridge Analytica scandal, in which a political consulting firm used millions of Facebook users' data, without their knowledge, in an attempt to sway the 2016 election in favor of Donald Trump.

"The evidence shows Mr. Zuckerberg was personally involved in Facebook’s failure to protect the privacy and data of its users leading directly to the Cambridge Analytica incident," Racine said in a statement.

The civil suit, filed in Superior Court of the District of Columbia, claims Zuckerberg violated the Consumer Protection Procedures Act, the District's general consumer protection law.

"This unprecedented security breach exposed tens of millions of Americans’ personal information, and Mr. Zuckerberg’s policies enabled a multi-year effort to mislead users about the extent of Facebook's wrongful conduct. This lawsuit is not only warranted, but necessary, and sends a message that corporate leaders, including CEOs, will be held accountable for their actions,” he said.

Meta has been at the center of a maelstrom of controversy since news of Cambridge Analytica first broke. In 2019, the Federal Trade Commission ordered Facebook to pay a $5 billion fine related to the scandal. Governments and regulators across the globe, including the FTC, are also cracking down on the social media giant via antitrust suits and legislation.

According to Racine, the latest suit against Zuckerberg comes as a result of an existing investigation and lawsuit his office filed against Facebook in the aftermath of the Cambridge Analytica scandal in 2018.

Racine claims that because Zuckerberg holds the largest number of shares of Meta and has final say over everything that happens at the company, he is ultimately responsible for Facebook's day-to-day operations. As a result, Racine claims, Zuckerberg is also responsible for the events that led to the scandal.
