President Donald Trump threatened on Thursday to immediately double tariffs on Mexican goods if Mexico fails to halt a caravan of roughly 1,500 migrants moving toward the U.S. border.

In a social media post, Trump stated that Mexico must stop the group now or face doubled tariffs. He noted that Mexican authorities, the governor of Texas, Border Patrol, and ICE had been informed, adding there would be no leniency.

The caravan, mostly from Central America, departed from southern Mexico earlier in the week. Mexican President Claudia Sheinbaum said her government has informed such groups that they will not be allowed into the United States and reported that no caravan has reached the northern border since early last year.

The threat comes as the United States and Mexico negotiate a new trade agreement following Trump's decision not to extend the USMCA pact. Mexico remains America's top trading partner, with significant cross-border commerce affecting states like New Mexico.

Homeland Security Secretary Markwayne Mullin said all assets would be used to secure the border and prevent the caravan from entering. Trump's move aligns with his administration's focus on immigration enforcement and using trade tools to pressure Mexico on border security.

Earlier tariffs imposed by the administration have drawn criticism from some New Mexico Democrats over potential costs to consumers and businesses, but the latest warning underscores the priority on stopping illegal crossings.
