Facebook is on trial in New Mexico over privacy concerns linked to the 2016 election. The state accuses the social media platform of failing to protect users from a data breach. The trial is expected to last four weeks. Opening statements are scheduled for Wednesday. Political consulting firm Cambridge Analytica bought user data harvested from millions of Facebook profiles to generate targeted ads during the 2016 election. Most U.S. states previously reached an agreement with Meta that addressed child safety concerns and privacy issues. New Mexico is the only state to push a case toward trial. Meta CEO Mark Zuckerberg isn't expected to testify in person.
