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 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.

The tallest peak in North America has been named Denali since 2015 when its name was officially changed under former President Barack Obama.
