President Trump's sweeping tariff policies face mounting legal challenges, casting uncertainty over global trade and domestic economic stability. Courts have ruled the tariffs unlawful due to overreach, while the administration aggressively appeals to the Supreme Court to uphold them, warning of potential economic catastrophe. The tariffs have led to disruptions across industries, including impacts on manufacturers like John Deere. A major refund effort looms should tariffs be struck down, but consumers are unlikely to benefit directly. Meanwhile, trade deals with partners such as the EU and South Korea hang in the balance, pending judicial outcomes.
