July 24, 2026 is not a date most Americans have circled on their calendars. Congressional Republicans are acutely aware of it, though — probably while staring at the ceiling at 2 a.m. That's the day Trump's Section 122 tariffs expire by statute, dropping a 150-day political hand grenade squarely in the middle of midterm campaign season. Someone has to make a decision. Nobody wants to make it. And the longer they wait, the worse it gets.
How a Trade War Became a Congressional Problem
In February, the Supreme Court did something that surprised almost no one who reads trade law and stunned almost everyone who makes it: it struck down Trump's sweeping tariffs imposed under the International Emergency Economic Powers Act in a 6-3 decision [1]. The ruling in Learning Resources Inc. et al. v. Trump was clear — IEEPA does not grant the president unilateral authority to impose broad tariffs, because taxing imports is fundamentally a congressional power. Trump, to his credit, moved fast. Within hours of the ruling, he pivoted to Section 122 of the Trade Act of 1974 — a narrower authority that allows the president to impose a temporary tariff of up to 15 percent when there's a "large and serious" balance-of-payments deficit [2]. The new 10 percent global tariff took effect February 24. Markets stabilized. The White House declared victory. And buried in the fine print of the proclamation was a detail that would haunt Republican strategists for the next five months: Section 122 tariffs are capped at 150 days. They expire at 12:01 a.m. on July 24, 2026, unless Congress votes to extend them. Congress now owns this.
