The warning comes as a federal appeals court hears arguments on the legality of his tariff policy. Trump added that if the court were to rule against him, “they should have done so LONG AGO,” claiming, “there is no way America could recover from such a judicial tragedy.”

Even though President Donald Trump often argues the US economy is booming under his watch, he warned Friday of a 1929-style crash if courts strike down his use of emergency powers to justify sweeping tariffs.

The president has crowed about the billions of dollars collected so far from tariffs. That money could be at risk if the White House loses the legal battle.
