The Supreme Court ruled against President Trump's global tariffs, stating that only Congress has the power to impose taxes, including tariffs. This decision marks a significant setback for Trump’s economic agenda. The ruling was 6-3, with dissent from Justices Alito, Thomas, and Kavanaugh. The court's decision does not prevent Trump from imposing duties under other laws, but public support for tariffs has been low. The economic impact of these tariffs is estimated at $3 trillion over the next decade.
