President Trump announced in a letter posted to social media on Saturday that he would place a 30 percent tariff on goods from the European Union, upending months of careful negotiations and further roiling what is one of the world’s most important economic relationships.

President Donald Trump on Saturday threatened duties of 30% on products from Mexico and the European Union, two of America’s biggest trading partners, in an ongoing tariff campaign that’s upended global trade since he retook office in January.

President Trump announced on social media that he is levying 30% tariffs against Mexico and the European Union. They are set to begin on August 1.

The 1996 agreement is set to expire Monday, which could raise the price of Mexican tomatoes and threaten thousands of Texas jobs.

If implemented, Trump's new 35 percent duties will be "separate from all Sectoral Tariffs," such as the 50 percent tariff on steel and aluminum imports. Trump also promised that, if Canada raises its own tariffs in response, then "whatever number [Canada chooses] to raise them by, will be added onto the 35% that [the U.S. charges]."

President-Musk shutdown scandal keeps escalating. Meanwhile, President’s tariff moves toward Mexico and Canada just got paused.
