Odaily Planet Daily reports that the U.S. Supreme Court began oral arguments on Wednesday regarding the legality of President Trump's massive retaliatory tariffs. In addition to the Supreme Court's liberal justices, several conservative justices also questioned the legality of Trump's tariffs. Chief Justice John Roberts stated that Trump's tariffs are taxes on Americans, which has always been a core power of Congress. Of the three justices appointed by Trump during his presidency, Neil Gorsuch and Amy Coney Barrett also raised challenging questions and delved into the arguments of those opposed to the tariffs. The Supreme Court has a conservative majority, 6-3. The Supreme Court is expected to announce its decision in December. The prediction platform Polymarket recently gave Trump a 27% chance of winning, down from 40% before the arguments and briefly dropping to a new low of 18% during the hearings.
