Trial likely to last five to seven weeks

California Attorney General Rob Bonta says this trial will last five to seven weeks. Both sides laid out their cases today, he says, adding that the states' case was particularly "compelling" with their first witness speaking of Meta knowing about harm to its users but failing to act. Meta's motto was to "move fast and break things", he says, adding, "Unfortunately, the thing that was broken here was the mental health of our children."
