Donald Trump launched his Presidential campaign on the issue of immigration, and after his Inauguration, arrests by Immigration and Customs Enforcement increased sharply. David Remnick talks with the staff writer Jonathan Blitzer, who has been covering Trump’s immigration policy all along. “The Trump Administration got smarter over the last four years,” he tells David Remnick. Rather than the “high drama” of executive orders, they began implementing rules and regulation changes across multiple departments that are much harder to undo. Blitzer explains that the cumulative impact fundamentally alters how the government thinks about immigration.
