After taking office, President Donald Trump ordered that the water bordered by the Southern United States, Mexico and Cuba be renamed to the Gulf of America. He also ordered America’s highest mountain peak be changed back to Mt. McKinley.

For nearly half a century, there’s been little thought about the name Congress gave to the Gulf of Mexico Fishery Management Council — until now. On Monday, President Donald Trump signed an order to rename the waterbody to the “Gulf of America” on federal agency maps, contracts, and other documents and communications.
