Mexican President Claudia Sheinbaum has responded sarcastically to U.S. President-elect Donald Trump’s proposal to rename the Gulf of Mexico as the Gulf of America.

Mexican President Claudia Sheinbaum dove into President-elect Trump’s chatter of geopolitical rearrangement Wednesday, proposing a name change for North America in response to Trump’s musings about the Gulf of Mexico.

The Mexican president responded to President-elect Trump's contention that the sea should have a more U.S.-centric designation by showing a map from 1607 during a Wednesday press conference. The map, which predates the founding of the United States by more than 150 years, labels all of North America as "América Mexicana” (“Mexican America”).
