Why it matters: The draft legislation is stunning. The bill essentially provides Trump a license to raise U.S. tariffs at will, without congressional consent and international rules be damned.

The details: The bill, titled the “United States Fair and Reciprocal Tariff Act,” would give Trump unilateral power to ignore the two most basic principles of the WTO and negotiate one-on-one with any country:

The “Most Favored Nation” (MFN) principle that countries can’t set different tariff rates for different countries outside of free trade agreements;

“Bound tariff rates” — the tariff ceilings that each WTO country has already agreed to in previous negotiations.
