As the incoming president pledges a crackdown, activist groups anticipating migrant raids are preparing to resist

Almost immediately after Donald Trump took office in 2017, he directed his administration to begin rounding up and deporting immigrants living in the country without authorization. He implemented a travel ban that caused chaos at airports, leaving families, students and scholars stranded. He also attempted to end the Deferred Action for Childhood Arrivals (Daca) program, which shields hundreds of thousands of people brought to the country as children from deportation and imposed a “zero-tolerance” at the US-Mexico border that led to the separation of thousands of families.

Many immigration advocates fear that the next four years could be even worse.
