Shortly after Trump’s proposed ultimatum, the mayor of Tijuana officially declared the migrant surge an international humanitarian crisis and called on groups like the United Nations for help. The mayor blamed the poor response of the Mexican federal government as the reason for his decision.
“They [Mexican government] have categorically omitted and not complied with their legal obligations,” he said. “So we’re now asking them and international humanitarian aid groups to bring in and carry out humanitarian assistance.”
