Watching the stock market fluctuate wildly in response to President Donald Trump's constantly changing tariff plans, you might wonder why the Framers would have given a single man so much authority over the U.S. economy. The short answer: They never did, and neither did Congress.
The Constitution vests Congress, not the president, with the power to "lay and collect taxes, duties, imposts and excises." Yet Trump has announced a dizzying array of "duties," including punitive tariffs on Mexican and Canadian goods, a 25 percent tax on imported cars and car parts, tariffs on Chinese goods as high as 145 percent, and a 10 percent general tax on imports that may rise further based on supposedly "reciprocal" rates that make no sense.
These levies amount to the largest tax hike since 1993 and raise tariffs more than the notorious Smoot-Hawley Act of 1930, which deepened the Great Depression by setting off a trade war. The main authority that Trump cites for these far-reaching, commerce-disrupting, price-boosting tariffs is the International Emergency Economic Powers Act (IEEPA), a 1977 law that says nothing about tariffs.
