And they've invoked the legal concept "the fruit of the poisonous tree" to invalidate the investigation.

Professor Elizabeth Joh teaches Intro to Constitutional Law and most of the time this is a pretty straight forward job. But when Trump came into office, everything changed. During the four years of the Trump presidency, Professor Joh would check Twitter five minutes before each class to find out what the 45th President had said and how it jibes with 200 years of the judicial branch interpreting and ruling on the Constitution. Acclaimed podcaster Roman Mars (99% Invisible) was so anxious about all the norms and laws being tested in the Trump era that he asked his neighbor, Elizabeth, to explain what was going on in the world from a Constitutional law perspective. Even after Trump left office, there is still so much for Roman to learn. What Trump Can Teach Us About Con Law is a weekly, fun, casual Con Law 101 class that uses the tumultuous activities of the executive, legislative, and judicial branches to teach us all about the US Constitution.
