Mexican President Claudia Sheinbaum took aim at U.S. President-elect Donald Trump on Wednesday, Jan. 8. The jab came one day after Trump suggested renaming the Gulf of Mexico as the “Gulf of America.”

During a news conference Wednesday, with an old global map displayed behind her, Sheinbaum sarcastically proposed that North America should be renamed “América Mexicana,” or “Mexican America.”

“Obviously, the Gulf of Mexico’s name is recognized by the United Nations, by a United Nations agency, but why don’t we call it (United States) Mexican America?” Sheinbaum asked. “Sounds nice, doesn’t it?”

Sheinbaum argued that the United States was once referred to by this name, according to a founding document from 1814. She also reiterated that the Gulf of Mexico has had its name since 1607.

When a reporter asked Sheinbaum about the incoming Trump administration, she said that Mexico would maintain good relations with the United States and President Trump. She cited the positive relationship Trump had with former Mexican President Andrés Manuel López Obrador, who also served as Sheinbaum’s political mentor.

While López Obrador was in office, he cultivated a relationship with Trump. Under U.S. pressure, Obrador’s government began blocking migrants from traveling north toward the U.S. border.

After Trump made the “Gulf of America” remark during a news conference on Tuesday, Jan. 7, he added, “Mexico has to stop allowing millions of people to pour into our country.”

He also claimed that Mexico is run by drug cartels and, in recent weeks, threatened Sheinbaum with tariffs on Mexican imports unless her administration does more to stop migrants and drugs from crossing the U.S.-Mexico border.

In response to the cartel comment, Sheinbaum said, “In Mexico, the people rule.”

Weeks ago, Sheinbaum initially said Mexico would not accept deportees from other countries. However, she later revised her position, stating that Mexico would accept deportees under certain conditions.
