Presidential pangs of conscience?

In April, President Trump said Deferred Action for Childhood Arrivals, the 2012 federal program to protect undocumented “Dreamer” immigrants who arrived in the U.S. as children, was a “very difficult subject for me.” It appears Trump was telling the truth. Trump’s administration has largely translated his presidential campaign’s hostility toward immigrants into government action. Efforts to impose a ban on travel from Muslim-majority nations have been comically inept — but persistent and seemingly heartfelt. Likewise, federal immigration agents have grown more aggressive, and less discriminating, in their pursuit of deportations. Even long-resident immigrants with American citizen children (and expert legal representation) are not safe.

At a congressional hearing last week, Thomas Homan, acting director of Immigration and Customs Enforcement, was explicit in describing the climate of fear his department seeks to create. “If you are in this country illegally, and you committed a crime by entering this country, you should be uncomfortable, you should look over your shoulder, and you need to be worried,” he said. “No population is off the table.”

To that end, the administration last week rescinded a 2014 plan to grant work permits and reprieves from deportation to potentially more than 4 million parents of U.S. citizens and green card holders. The plan had been stymied in court. But the move was nonetheless another brick in the anti-immigrant wall.

Yet supporters of immigration restrictions couldn’t help noticing that, once again, the Trump administration had failed to strip almost 800,000 Dreamers of the legal protection they had won under President Barack Obama’s 2012 executive action. A post by the Department of Homeland Security stated: “This rescission will not affect the terms of the original DACA program as outlined in the June 15, 2012 memorandum.” It added: “No work permits will be terminated prior to their current expiration dates.”

Obama’s DACA plan had pushed the limits of executive action. Ever since, immigration restrictionists
