President Donald Trump faces a major legal challenge as multiple states plan to file a lawsuit against his new 10% tariff order on imported goods. The states are taking action after the Supreme Court struck down Trump's earlier sweeping duties last month, setting up another constitutional battle over executive authority in trade policy.

The legal challenge comes as Trump attempts to implement a scaled-back version of his import tax strategy. The states argue that the president lacks constitutional authority to unilaterally impose tariffs without congressional approval. This follows a pattern of Trump's trade policies facing judicial scrutiny, with the Supreme Court's recent ruling effectively invalidating his broader tariff framework.

Legal experts suggest the states' lawsuit could significantly delay or derail Trump's latest tariff initiative. The case raises fundamental questions about the separation of powers and presidential authority in international trade matters. With the Supreme Court already having ruled against Trump's previous approach, the administration may face an uphill battle in defending its new 10% tariff structure against the multistate challenge.
