Trump stated that calculating the amount owed and identifying who, when, and where to make payments would "take many years." The tariffs, initially announced last April, are being challenged by small businesses and a group of U.S. states who argue that the president exceeded his authority in imposing the levies on goods entering the country.

The legal challenge centers on the argument that Trump overstepped his authority in implementing the tariffs. Challengers contend that the tariffs, which are essentially taxes on imported goods, require congressional approval, which was not obtained. The administration, however, maintains that the tariffs were enacted under existing laws granting the president broad powers in matters of national security and trade.

Trump has repeatedly expressed frustration over the legal battle, writing on Truth Social that if the Supreme Court does not uphold his tariffs, "WE'RE SCREWED." The outcome of the Supreme Court's decision could have significant implications for U.S. trade policy and the president's ability to unilaterally impose tariffs.

The Supreme Court's ruling is expected to clarify the extent of presidential power in trade matters. A decision against the administration could lead to a rollback of existing tariffs and potentially require the government to issue refunds to businesses that have paid them. Conversely, a ruling in favor of the administration would affirm the president's authority to impose tariffs without explicit congressional approval, potentially paving the way for further trade actions. The decision is anticipated to be released as early as Wednesday.
