Mexico's President Claudia Sheinbaum responded sarcastically on Wednesday to U.S. President-elect Donald Trump's proposal to change the name of the Gulf of Mexico to the Gulf of America. Standing before a global map in her daily press briefing, Sheinbaum proposed dryly that North America should be renamed “América Mexicana,” or “Mexican America,” because a founding document dating from 1814 that preceded Mexico's constitution referred to it that way.
