California Attorney General Xavier Becerra said he asked the San Francisco Superior Court to order Facebook (FB) - Get Report to comply with a subpoena connected to an investigation into the social-media company's privacy practices.
The subpoena was issued on June 17, 2019, a statement from the attorney general's office said.
"The California Department of Justice, pursuant to its statutory authority, issued investigative subpoenas against Facebook starting back in June 2018 to examine the company's actions and business practices and any violations of user privacy. The responses we have received to date are patently inadequate," Becerra said.
On June 4, 2018, the Attorney General issued an investigative subpoena requiring Facebook to produce documents related to its business practices.
The inquiry was launched in response to the Cambridge Analytica scandal, which placed Facebook at the center of the 2016 presidential election. Cambridge is an "app provider that accessed 87 million Americans' data and used it to conduct election-related disinformation campaigns," the AG's office said.
Will Castleberry, Facebook's vice president of state and local policy, told CNBC that the Menlo Park, Calif., company has "cooperated extensively" with the investigation, but he did not address the state attorney general's filing that said it hasn't complied with subpoenas.
Becerra said, "Our work must move forward. We are left with little choice but to seek a court order compelling Facebook to faithfully comply with our duly authorized subpoenas."
Facebook shares are off 1.3% to $191.75 on Wednesday.
