U.S. President Donald Trump is set to address the public concerning the Supreme Court's recent ruling that deemed tariffs he imposed under national emergency powers as illegal. The press conference is scheduled for approximately 7:45 PM Finnish time, and will be broadcast live by Ilta-Sanomat. This follows the Supreme Court's decision which clarified that the International Emergency Economic Powers Act (IEEPA) does not grant the president unilateral authority to impose tariffs, emphasizing that congressional approval is required for such actions.

In its ruling, the Supreme Court highlighted the limitations of the president's power under the IEEPA, stating that any tariffs considered should have gone through Congress to ensure representation and oversight. The implications of this ruling are significant as it reinforces the principle of checks and balances within the government, especially concerning economic measures that can impact international trade relations.

Following the ruling, President Trump expressed his disapproval, labeling the decision as 'shameful' during an informal commentary session. His upcoming statements are anticipated to reflect his stance on the legal constraints imposed by the court and his views on the broader implications for future tariff policies and executive power. The live broadcast by Ilta-Sanomat aims to provide real-time coverage of the president's responses and the ensuing public discourse surrounding this pivotal legal ruling.
