The Trump administration's fierce crackdown on the "migrant caravan" has caused the 6,000-strong group to stall in Tijuana, Mexico; with many choosing to return home rather than wait months for their asylum claims to be processed by American authorities.
"Since that caravan formed in mid-October, we've seen 90,000 people come to our border, 85 percent of those crossing illegally between ports of entry, and all lured by the fact that our legal framework has huge gaps that create the opportunity to stay in the USA while awaiting your court hearing, even if they don't have a lawful permission or protection claim".
