Zuckerberg Named in Suit by Washington, D.C., Attorney General

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.

Mr. Racine said he made the decision after reviewing company documents as part of discovery in the lawsuit. “It’s clear Mr. Zuckerberg knowingly and actively participated in each decision that led to Cambridge Analytica’s mass collection of Facebook user data and Facebook’s misrepresentations to users about how secure their data was,” he said.

The development is a reminder of the legal threats facing Facebook and Mr. Zuckerberg. The Washington, D.C., lawsuit was filed after the disclosure that Cambridge Analytica, a now-defunct political consulting firm, had improperly mined user data.

More recently, officials have been looking into company documents disclosed by a former employee, Frances Haugen, and reported on by The Wall Street Journal, that show the company knows its platforms are riddled with flaws that cause harm.

The Journal’s articles and subsequent Senate hearings have motivated lawmakers to start writing legislation to address perceived concerns about the company’s platforms. Mr. Racine’s action shows the courtroom could also be an avenue to address those concerns.

“We think Facebook may now face a similar challenge from increased litigation as Tobacco, or more recently, OxyContin,” Blair Levin, an analyst with New Street Research, wrote in a recent note to clients. He said that class-action lawsuits from private plaintiffs are also a threat to the company’s bottom line.

Much of the new allegations against Mr. Zuckerberg is redacted due to a protective order in place in the litigation, Mr. Racine said. The attorney general, whose term expires in early 2023, has said he wouldn’t seek re-election.

Also Wednesday, Sen. Richard Blumenthal (D., Conn.) sent a letter to Mr. Zuckerberg, inviting him to testify at a hearing on Instagram and kids. “Parents across America are deeply disturbed by ongoing reports that Facebook knows that Instagram can cause destructive and lasting harms to many teens and children, especially to their mental health and wellbeing,” Mr. Blumenthal wrote. He also said he was “disappointed that Facebook has been unwilling to be fully transparent … and appears to have concealed vital information from us about teen mental health and addiction.”

He indicated that Adam Mosseri, the head of Instagram, could testify instead.

Facebook had no immediate comment on the request.
