President Donald Trump is renaming the Gulf of Mexico the Gulf of America. But how will that change go into effect – and will everyone call it that?

Donald Trump will order the renaming of the Gulf of Mexico and Alaska’s Mount Denali in his first hours as the 47th president, The Post has learned.

Among the first executive orders signed by President Donald Trump was an order to rename the Gulf of Mexico to the newly named "Gulf of America." "President Trump is bringing common sense to government and renewing the pillars of American civilization," the newly inaugurated president's executive order said.
