The U.S. Department of Justice on Thursday filed a long-anticipated lawsuit against Apple, alleging the tech giant shut out competitors from accessing software and hardware features of its ubiquitous iPhone.

The case filed in federal court in New Jersey marks at least the third DOJ case against Apple in the last two decades alleging antitrust violations. It comes as Biden administration appointees at the DOJ and Federal Trade Commission continue to unleash what competition experts call the most aggressive antitrust enforcement in decades.
