Opening statements started Tuesday in a pivotal trial for Meta Platforms in a California federal court, where states are seeking billions of dollars in damages for social media harms to children. Attorneys general from California, Colorado, Kentucky and New Jersey are seeking extensive financial damages plus changes to how the company operates Facebook and Instagram. Twenty-nine states sued the tech giant in 2023 over child safety and privacy. The other 25 will go to trial later. The company also faces lawsuits in state courts. Meta said in a statement that it believes it has a strong case.
