Direction to implement this was in the executive order Trump signed which banned people from the 7 countries that the Obama administration had built a database of nationals of those countries. When I read the executive order I was quite troubled to see this. I also noticed the exit tracking part of the order went undiscussed in the media. I searched to see if anyone else had noticed but i didn't find anyone else talking about it. It almost feels like some of the more outrageous parts of the order (eg ignoring green card holders) were designed to draw attention away from the real point: slipping in exit tracking without people noticing (because they are too busy distracted fighting the other parts of the order).
