President Donald Trump signed numerous executive orders on his first day in office on Monday—one of the executive orders was to rename Mt. Denali and the Gulf of Mexico.

President-elect Trump will sign executive orders renaming the Gulf of Mexico and Mount Denali after his inauguration on Monday.

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.

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.”

Florida Gov. Ron DeSantis has already embraced the change. He cited the new name in an executive order earlier this week attributing inclement winter weather to a “low pressure moving across the Gulf of America.

President Donald Trump started his second administration with a blitz of policy actions to reorient the U.S. government.
