Minnesota Attorney General Keith Ellison announced Tuesday that he is suing TikTok, alleging the social media app is “preying on Minnesota’s young people” through manipulative and deceptive practices.

More than a dozen other Democratic attorneys general have sued TikTok for its alleged impact on young users and “deceptive practices.” Ellison’s lawsuit, filed in state court, argued that the app violates a Minnesota law against deceptive trade practices and consumer fraud.
