A federal trial is underway in California, involving Meta and claims about the harm its platforms cause to youth mental health. Jury selection started on Wednesday. The trial, expected to last six to eight weeks, is part of a larger lawsuit filed in 2023.

Meta is facing 29 states in the federal multidistrict lawsuit, but only four states are involved in this particular trial. Further details about the trial and the allegations against Meta are available from the source, including information about the lawsuit and the states involved.
