Thousands of Americans in Puerto Rico are without power after Hurricane Fiona roared through last week. Idling off the island’s coast is a ship that reportedly carries 300,000 barrels of diesel fuel from Texas. Yet unloading that fuel is illegal without a Jones Act waiver, which the Biden Administration hasn’t granted.

The Jones Act, also known as the Merchant Marine Act of 1920, is protectionism at its worst. The law says waterborne cargo between U.S. points must be carried by ships that are primarily built, owned and crewed by Americans. This raises shipping prices, while shifting cargo to trucks, which are less efficient and worse for the environment. The law also explains why wintry Boston imports Russian liquefied natural gas.
