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.

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 post included a link to the New York Post, which reports it has learned that Trump will call for the Gulf of Mexico to become the Gulf of America. Denali will return to Mount McKinley — President Barack Obama changed the name of the continent’s highest mountain in 2015.

As president, Trump can take the action to rename the body of water, although other countries don’t have to adopt the new name.
