A trade court’s decision Wednesday evening isn’t just a blow to President Donald Trump’s tariff plans. It calls into question the entire governing strategy of an administration constructed on an expansive vision of executive power.

The Trump administration appealed a ruling by a federal trade court invalidating many of the president’s recent tariffs.

Trump's determination to move fast could slow implementation of his tariff regime. It also threatens to cost him credibility.

President Donald Trump said twice Friday that China had breached the terms of the bilateral trade agreement but offered scant details.
