There have been a host of civil servants purged from a litany of federal services for this reason. You don't have to look very hard to find them. Example: https://www.npr.org/2025/09/10/g-s1-87947/fbi-lawsuit-firing....

Another (higher profile) example are the baseless threats of criminal indictments against Jerome Powell -- it is impossible to argue that these threats have been made for any reason other than that he, as a nonpartisan official, defied the president's demands to execute his duties as fed chair in such a way (that is, poorly) so as to put a temporary thumb on the scale for the current admin.

The more important question, I think, is how many folk in explicitly nonpartisan functions are choosing not to break step with the current admin for fear of some sort of (likely professional) reprisal. I'm not alleging that they're disappearing dissenters or anything that inflammatory, but it would be intellectually dishonest to contend that there isn't a long, well-documented trail of malfeasance here.
