The Trump administration is defined by hostility to expertise and has silenced or purged people who know things across agencies.

At a fundamental level, they’re just hostile to the idea of expertise in any domain, in pretty much every agency where there’s something to know, where there’s technical stuff that you need to know to make good decisions. The people who actually know things, or the people who are willing to speak up about what they know, have been silenced, purged.
