WASHINGTON — President Trump announced on Saturday that he intends to raise his planned global tariff to 15%, an increase from the 10% levy imposed just one day prior. The move comes as a direct challenge to the U.S. Supreme Court, which on Friday struck down his previous set of sweeping global duties.

In a series of social media posts, Mr. Trump blasted the high court’s decision as “ridiculous, poorly written, and extraordinarily anti-American.” He stated that the escalation to 15%—the maximum allowed under the specific legal provision he is now utilizing—is a necessary step to stop foreign countries from “ripping the U.S. off.”

Bypassing the Judicial Roadblock

Infuriated by Friday’s ruling, which held that the power to tax belongs to Congress rather than the Executive branch, Mr. Trump signed a new proclamation enabling him to bypass the legislature once more. While the previous tariffs relied on the International Emergency Economic Powers Act (IEEPA), the new 15% levy invokes Section 122 of the Trade Act of 1974.

“Effective immediately,” the President wrote, the Worldwide Tariff will be raised to the “fully allowed, and legally tested, 15% level.” These new duties are currently scheduled to take effect starting February 24, although legal experts anticipate immediate challenges to this new interpretation of trade law.

Continuing the “MAGA” Trade Agenda

Mr. Trump emphasized that his administration would continue to “determine and issue the new and legally permissible Tariffs” to further his “Making America Great Again” agenda. Beyond these temporary 150-day tariffs, the President indicated he is pursuing additional duties through other federal laws that require formal investigations by the Commerce Department.

It is important to note that the Supreme Court’s ruling did not impact tariffs issued under different legal authorities, such as the existing levies on steel, aluminum, and auto imports. The administration remains defiant, with the President signaling that a permanent judicial defeat on one legal front will only lead to the opening of another.
