Economist flags Trump's one-day flip flop after having 'months to prepare' his next move

Donald Trump had "literally months to prepare" a response but still fumbled it, changing his mind after one day, according to an economist on Saturday.

The Supreme Court smacked down Trump's tariff policies in a stunning rebuke from the most conservative high court in modern history, and Trump responded by waffling his new plan, according to noted economist Justin Wolfers.

In response to the decision, Trump first said he had enacted a 10% global tariff by executive order. Then on Saturday, he raised it to 15% via a Truth Social Post.

"Based on a thorough, detailed, and complete review of the ridiculous, poorly written, and extraordinarily anti-American decision on Tariffs issued yesterday, after MANY months of contemplation, by the United States Supreme Court, please let this statement serve to represent that I, as President of the United States of America, will be, effective immediately, raising the 10% Worldwide Tariff on Countries, many of which have been 'ripping' the U.S. off for decades, without retribution (until I came along!), to the fully allowed, and legally tested, 15% level," Trump wrote this weekend.

Wolfers flagged the chaotic nature of the response, saying on X, "The President had literally months to prepare his response to the Supreme Court ruling, yet couldn't even stick with his decision on the s.122 (temporary) tariff from Friday to Saturday, raising it from 10% to 15%."
