Last week’s announcement that six more countries—including genocidal Myanmar—will be added to the “travel ban” list of countries whose citizens are barred from immigrating to the United States is just the most recent effort by the Trump Administration to demonize immigrants and close our borders to those fleeing repression and violence. And with the presidential election campaign now officially underway following this week’s Iowa caucus, we can expect ever more draconian attacks on immigrants as Trump gears up for the November election.

Starting with the original travel ban Trump put into place shortly after his January 2017 inauguration, his broad assault on immigration and refugees has spawned a wide array of legal challenges that have presented the courts with fundamental questions about the power of the President, the contours of the vast and complicated Congressional statutory scheme regulating immigration, the role of the judiciary in adjudicating disputes over immigration policy, and the constitutional rights of noncitizens either present in the United States or at the border seeking refuge here.
