If you want a detailed understanding of what Trump is doing with his executive order on immigration you need to listen to KrisAnne Hall deconstruct the entire issue within the boundaries of the Constitution.

You can go to mainstream media and get a talking head spouting off some opinion that is based on little fact, or you can really be informed about this entire issue in light of Presidential authority within the Constitution by listening to someone who has the knowledge and training to walk us all through article/section/clause of the Constitution. Our supreme law of the land.
