The USDA had previously reopened certain ports, such as Douglas, Arizona, after Mexico's efforts to control the screwworm pest.

The US has closed its ports of entry to Mexican cattle for fear of the parasitic, flesh-eating worm spreading north.

Sheinbaum has become Mexico’s toughest representative against Trump’s hardcore policies — winning the favor of Mexico’s younger voters along the way.

The Mexico City Anti-Gentrification Front, one of the organizations behind the protest, stated it was “completely against” any acts of physical violence and denied that the protests were xenophobic. Instead, the organization cited failures by the local government to address the root of the problems.

Mexican President Claudia Sheinbaum said on Thursday that the U.S. decision to halt cattle imports from Mexico again over the flesh-eating screwworm pest was "exaggerated."

The U.S. has closed its southern border again to livestock imports, saying that a flesh-eating parasite has moved further north in Mexico than previously reported.

"First, we need to ask ourselves: what is gentrification?" Sheinbaum said before dedicating a large portion of her morning press conference to the topic.
