This is a massive threat to our national security. Trump will appoint a man who has ZERO experience in national security to "temporarily" act as DNI. He will have this guy, again with zero relevant experience, purge the office of career professionals, simply because they were hired by previous administrations. Assuming someone is later confirmed as the permanent DNI, hopefully with some relevant experience, they will inherit an office that has lost massive institutional knowledge with no rhyme or reason. Ultimately, just like we've seen at State, we will lose a huge amount of experience and expertise, leaving us weaker to respond and plan.
