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.

Renaming Denali back to Mount McKinley, along with renaming the Gulf of Mexico the Gulf of America, will be among the nearly 200 day-one executive orders Donald Trump is expected to sign after being sworn into office for his second term as president, according to published reports.

President Donald Trump said the Gulf of Mexico will be called Gulf of America, while the Denali mountain peak will revert to its old name, Mount McKinley.

Renaming it the Gulf of America would apply only in the US. And the long global history of disputed place names suggests it could be a brief experiment anyway.

As part of a torrent of decisions he issued hours after taking office, President Donald Trump declared that the name of America’s tallest mountain be changed from Denali to Mount McKinley, and that the Gulf of Mexico be renamed “The Gulf of America.”

Federal changes have to be made, but other countries and private companies can keep using "Gulf of Mexico." Here's why.

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.

The order Trump signed instructs the Interior Department to update the Geographic Names Information System to reflect the renaming of the Gulf and remove all references to the Gulf of Mexico. It says all federal references to the Gulf of America, including on agency maps, contracts, and other documents and communications shall reflect the renaming.

Gov. Ron DeSantis may have been the first official to use President's Trump's new name for the Gulf of Mexico in an official capacity.

Mexican president says President Trump can call the gulf whatever he wants but that the world will still call it the Gulf of Mexico.

The president made the name change through one of dozens of executive orders he signed on Monday. Former President Barack Obama’s administration ordered that the mountain be renamed as Denali in 2015.
