Alaskans are responding after President Donald Trump changed the name of North America's tallest peak from Denali back to Mount McKinley.

The tallest mountain in the United States has been officially reverted to Mount McKinley, the U.S. Department of the Interior announced in a press release Friday. The official action comes four days after President Donald Trump signed an executive order on his first day back in office that also changes the name of the Gulf of Mexico to the Gulf of America.

The president wants to honor a predecessor, William McKinley, by returning his name to North America’s highest peak. The state’s senators prefer the Native name.
