In all honesty, while I don’t like this, I’m surprised they weren’t doing this already. A portion of the process is intended to weed out extremism and potential threats trying to find a way into the country. It seems to at reviewing social media posts for problematic content would have been standard procedure already.

The part I have a problem with is who gets to determine what is extremism. In the past that determination likely came from non-partisan federal acency rule-making. Now it is likely coming from the partisan administration.
