Donald Trump is pressing to restore a hardline tariff regime after a Supreme Court ruling curbed the president's unilateral authority to impose trade barriers. The decision shifts the battleground to Congress, where lawmakers now face a choice that could reshape U.S. trade policy for years.
The court's limits
The Supreme Court ruled that the executive branch cannot levy tariffs without clear congressional approval. That directly undercuts the legal basis Trump used during his first term, when he imposed sweeping duties on steel, aluminum, and Chinese goods under national security and trade law provisions. The ruling forces a rethinking of how far the president can go on trade.
Trump's response
Trump has made clear he wants to bring back those hardline policies. With the court narrowing his options, he's now calling on Congress to act. The former president argues that lawmakers should grant the executive broader tariff authority — or risk losing leverage in trade negotiations. His push sets up a clash between those who want to reclaim congressional power over trade and those who back a tougher White House stance.
What Congress might do
The ruling opens the door for legislative changes that could redefine U.S. trade policy long-term. Lawmakers are weighing whether to give the president new tariff powers, impose new constraints, or leave the current system in place. Any move would have ripple effects on global trade relationships, from allies to major competitors. No bill has been introduced yet, but the debate is expected to intensify in the coming months.
No timeline has been set for legislative action. The question now is whether Congress will hand Trump the tools he wants — or keep them for itself.
