(CNBC) — A group of 50 Central American migrants who set out from southern Mexico in late March have reached the U.S. border, having endured the long journey despite threats by President Donald Trump to secure the border with National Guard personnel.
Since peaking at around 1,500 people, the so-called migrant “caravan” has dwindled under pressure from Trump and Mexican migration authorities, who vowed to separate those migrants with a right to stay in Mexico from those who did not.
“Since yesterday, some began to cross into the United States to turn themselves in from Tijuana and request asylum. We understand more of (the migrants) will do the same,” said Jose Maria Garcia, director of Juventud 2000, an organization dedicated to assisting migrants.
