Over the course of President Donald Trump’s first year in office, his administration’s top immigration priority has shifted subtly. He’s talking less about deporting “bad hombres” and talking more — a lot more — about how “chain migration” is bad for the United States.
“We have to get rid of chainlike immigration, we have to get rid of the chain,” Trump told the New York Times’s Mike Schmidt in an impromptu interview at his West Palm Beach golf club in December. He followed it up, as he does, with a tweet:
The Democrats have been told, and fully understand, that there can be no DACA without the desperately needed WALL at the Southern Border and an END to the horrible Chain Migration & ridiculous Lottery System of Immigration etc. We must protect our Country at all cost!— Donald J.
