Trump reiterated that the president has the authority to decide whether to impose tariffs.

On November 9, Trump reiterated that the President of the United States has the authority to decide whether to impose tariffs: “So, let's be clear? The President of the United States is allowed (and Congress fully approves!) to stop all trade with foreign countries (which is much more complicated than imposing tariffs!), and can issue licenses to foreign countries, but cannot impose simple tariffs on foreign countries, even for national security. This is completely not the intention of our great founding fathers! This is simply ridiculous! Other countries can impose tariffs on us, but we cannot impose tariffs on them? This is simply their dream! Businesses flocking to the U.S. is entirely due to tariffs. Has the U.S. Supreme Court not been informed of this? What is going on?” This Wednesday, the U.S. Supreme Court held oral arguments on the legality of Trump's large-scale imposition of reciprocal tariffs. Besides the liberal justices of the Supreme Court, several conservative justices also expressed doubts about the legality of Trump's tariffs. Chief Justice Roberts (John Roberts) stated that Trump's tariffs are taxes on Americans, which always belongs to the core power of Congress. Among the three justices appointed by Trump, Gorsuch (Neil Gorsuch) and Barrett (Amy Coney Barrett) also raised questions of doubt and deeply explored the arguments of tariff opponents. The Supreme Court has a conservative majority, with a ratio of 6:3. The Supreme Court could announce its ruling in December.
