Trump administration ruins an FBI agent’s career because he’s friends with the wrong guy. Every other agent now has to worry that if they do something that bothers Trump, even something that is legal and legitimate!, they might lose their job.
This is not the way to retain the best employees for our government! Nor how a democratic country operates.
Trump removes people with great experience for bad reasons, then puts in shills he thinks are loyal. The remaining underlings see that the way to keep their jobs is to shut up, and do what they’re told, even if the shills at the top don’t know what they’re doing.
