The Department of the Interior says they're moving quickly to implement President Donald Trump's executive order to rename Mount Denali and the Gulf of Mexico.

In one of his first acts as president, Donald Trump used an executive order on Monday to rename the Gulf of Mexico and Denali in Alaska. To start, Trump re-named the Gulf of Mexico the “Gulf of America,” following through on a promise he made during his campaign.
