“IEEPA nowhere mentions tariffs, duties, imposts, or taxes, and no other President in the statute’s nearly 50-year history has claimed that it authorizes tariffs,” the companies added in a filing with the appeals court.

Back in April, Trump had claimed to have done "over 200 deals" in an interview with Time Magazine, and trade advisor Peter Navarro had said that "90 deals in 90 days" was possible. The country has fallen far short of that, with only eight deals in 120 days, including one with the 27-member European Union.

The clock is ticking closer to President Trump’s latest tariff deadline of Aug. 1. And while several more deals have been reached, talks with many countries are still in flux.
