Mexico's president sarcastically said that the U.S. should be called "Mexican America" after Trump's vow to rename the Gulf of Mexico the "Gulf of America."

Claudia Sheinbaum gave a sarcastic history lesson to the president-elect, while Canada has also hit back at comments about it becoming the 51st US state.

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”).
