Trump claims he'll rename the Gulf of Mexico to 'Gulf of America'

President-elect Donald Trump declared in a proposal out of left field on Tuesday that his administration will rename the Gulf of Mexico the "Gulf of America" in his latest attack on Mexico.

"We're going to change because we do most of the work there and it's ours," Trump said. "It's appropriate, and Mexico has to stop allowing millions of people to pour into our country," Trump said in a wide-ranging news conference.

Trump criticized Mexico for the increase of drugs coming into the U.S. and said that he would make Mexico and Canada pay through "substantial tariffs."

"We want to get along with everybody. But you know ... it takes two to tango," he said.

Shortly after, longtime Trump ally Republican Rep. Marjorie Taylor Greene announced on X that she had instructed her staff to begin drafting legislation to change the name of the gulf.

"This is important to begin funding the changing of maps for all agencies within the federal government, like the FAA and the military," she said in her post.

The Gulf of Mexico has been identified by several names through its history, with "Golfo de Mexico" first appearing on maps in the mid-16th century when Spain occupied the areas now known as Cuba to the south, Mexico to the west and the the U.S. states that surround it to the North.

The Gulf of Mexico is one of the largest and most important bodies of water in North America. It's the ninth-largest body of water in the world and covers some 600,000 square miles.

Half of the U.S. petroleum refining and natural gas processing capacity is located along the Gulf of Mexico, according to the National Oceanic and Atmospheric Administration, and it supplies about 40% of the nation's seafood.

Its more than 17.2 million acres of marsh and nearly 30,000 miles of tidal shoreline draw millions of tourists to the area each year, the NOAA says, and it's home to hundreds of fish species.

Trump's promise to rename the gulf isn't the first.

In 2012, then-Mississippi State Rep. Steve Holland proposed a bill that also would have renamed the gulf into the "Gulf of America," however the Democrat backtracked and said he was joking and using it as a way to criticize his Republican colleagues over their anti-immigrant stances.

"They are trying to really discriminate against immigrants, which offends me severely," Holland told ABC News in 2012. "I just thought if we're gonna get into it, we might as well all get into it, it's purely tongue and cheek."

Stephen Colbert suggested the same name during the 2010 BP oil spill on his Comedy Central show "The Colbert Report."

"We broke it, we bought it," he joked.
