President Donald Trump said Wednesday that he may go to the Supreme Court next month to hear oral arguments in the key tariff case that could decide the fate of his sweeping protectionist trade agenda.

Trump would apparently be the first sitting US president to take part in oral arguments before the Supreme Court.

“We have a major case before the Supreme Court, and I tell you, this is one of the most important cases in the history of our country,” Trump said in the Oval Office. “If we don’t win this case, we will be a weakened, troubled, financial mess for many, many years to come.”

“That’s why I think I’m going to go to the Supreme Court to watch,” Trump said.

The Supreme Court is scheduled to hear arguments on November 5 in the customs case, known as VOS Selections v. Trump, listen.

The case centers on the question of whether the law that Trump has used to impose his major country-specific tariff policies — including his so-called reciprocal tariffs and his fentanyl-related tariffs — actually authorizes these trade measures.

The White House did not immediately respond to CNBC’s request for additional comment on Trump’s comments.
