It was a key promise on the campaign trail, and now President Donald Trump's crackdown on immigration across the country is in full effect — but not without opposition, spawning an ongoing wave of legal challenges and protests.

This week on Straight Talk, two experts in the field of immigration try to detangle some of the misconceptions surrounding the president's efforts, aiming to peel back some of the layers of the debate over immigration, from legal battles to the Trump administration's tactics to what's driving voter sentiment about foreign citizens entering the country.

Professor Juliet Stumpf is a professor of law at Lewis and Clark Law School with expertise in both immigration law and the intersection of immigration and criminal law. Professor Alexander Sager is an associate professor of philosophy at Portland State University who specializes in political philosophy and the ethics of migration.
