[Trump Claims U.S. President Has the Right to Impose Tariffs and Questions Supreme Court's Stance] U.S. President Trump posted on social media stating that the President of the United States has the full authority to completely ban trade with a certain foreign country, a power that has already been approved by Congress and is even more severe than imposing tariffs. However, he questioned why the President does not have the authority to impose tariffs on a certain foreign country, even for the purpose of safeguarding national security. He argued that this situation is inconsistent with the expectations of America's Founding Fathers and criticized the fact that other countries can impose tariffs on the U.S., while the U.S. cannot impose tariffs on them. Additionally, he mentioned that tariff policies are a key factor in attracting businesses to the U.S. and raised doubts about whether the U.S. Supreme Court understands the relevant circumstances.
