The last-minute deal had echoes of Trump's first administration, when he threatened Mexico with tariffs and Sheinbaum's predecessor Andrés Manuel López Obrador defused the threat, sending thousands of troops under his newly created National Guard to deter migrants from crossing the border.

President Claudia Sheinbaum’s government said the National Guard members had redeployed to 18 cities and towns along the U.S.-Mexico border as part of a deal to delay U.S. tariffs.
