The election of Donald Trump for a second term has produced many predictions on the future of antitrust enforcement. Many focus on federal antitrust enforcers’ likely policies and priorities. But the federal government is not the only antitrust enforcer in town. State attorneys general also have broad antitrust enforcement authority pursuant to state statutes, which are typically based on federal antitrust statutes but are sometimes even broader.

Predicting the landscape for antitrust enforcement under the second Trump Administration therefore requires analyzing more than federal antitrust regulators; state attorneys general must be considered. And the impact of state antitrust enforcers may well be profound.
