In my Georgetown class last week, we got into a lively discussion about President Trump’s refugee travel ban. One of my students has her law degree from Harvard and is now studying for a Master’s degree in public policy at the McCourt School of Public Policy, where I teach. She had been at D.C. airports most of the previous weekend, trying to help many of the international arrivals who had been detained. “This administration just doesn’t accept the rule of law,” she lamented, and said how discouraged she was feeling.
