In a flurry of first-day-in-office activity, Donald Trump has signed an order to rename the 617,800 sq mile Gulf of Mexico and Alaska’s 20,000ft mountain Denali.

The Gulf of Mexico will be renamed the Gulf of America, and Denali, the highest peak in North America, will revert to Mount McKinley – the name it was called before Barack Obama changed it in 2015.

The renaming of the two natural features is to honor “American greatness”, according to a preview of the orders obtained by the New York Post.
