The news broke shortly before he was sworn in Monday morning, and Trump confirmed it during his inaugural address. The order will rename the Gulf of Mexico to the Gulf of America, and Mount Denali to Mount McKinley, which was the official name recognized by the federal government from 1917 until 2015.

The executive order will direct the secretary of the interior to change the name to "Gulf of America” for use on official maps and throughout the federal government, according to the New York Post, which first reported the news. Trump has nominated Republican North Dakota Gov. Doug Burgum to the Department of Interior.

Among the first executive orders set to be signed by President Donald Trump will be an order to rename the Gulf of Mexico to the newly named "Gulf of America." The plan will be enacted "a short time from now," Trump said during his inaugural address at the Capitol Rotunda on Monday.
