Trump's a fan of President William McKinley, giving the Canton, Ohio, native a major shout-out in his inaugural address.

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.”

The mountain was previously called Mount McKinley, after the Ohio native former president. The name was officially changed in 2015.

The 47th president’s affinity for the 25th president is understandable, if not quite accurate.

During his inaugural address, President Donald Trump suggested he wants to revert the name of North America’s tallest mountain — Alaska’s Denali — to Mount McKinley. Here's why:

During his inaugural address, President Donald Trump vowed to change the name of Denali in Alaska back to Mount McKinley.

In 2015, the name of the peak was changed during the Obama administration to reflect the traditions of Alaska Natives and preference of many Alaskans.

The move, the 47th president says, will ‘restore the name of a great president’ to ‘Mount McKinley, where it should be and where it belongs.’

President Donald Trump has officially issued an executive order to change Denali, the tallest peak in Alaska and North America, back to Mount McKinley.

President Donald Trump says he’s changing the official name of Alaska’s — and North America’s — tallest peak from Denali back to Mount McKinley. It’s the latest chapter in a long struggle over what the mountain should be called.
