A coalition of 25 U.S. states filed a lawsuit on August 4, 2026, challenging the Trump administration's new tariffs imposed on 60 trading partners.
The plaintiffs argue that the administration lacks the constitutional authority to unilaterally raise taxes, claiming the move will cause significant economic harm to domestic industries.
The legal challenge seeks an immediate injunction to halt the implementation of the tariffs, which critics describe as an illegal expansion of executive power.
