Trump Announces 'Remain in Mexico' Policy — Migrant Protection Protocols (2019-01-25)

The Trump administration formally implements the Migrant Protection Protocols (MPP), also known as 'Remain in Mexico,' requiring asylum seekers to wait in Mexico while their US immigration cases are processed. Over 70,000 migrants are returned to Mexico under the policy. Human rights organizations document widespread violence, kidnapping, and rape of migrants forced to wait in dangerous Mexican border cities. Biden ends the policy in 2021; Trump reinstates it in 2025.
