I can't think of a single department in the massive federal bureaucracy where the employees are not out to sabotage the Trump administration.
I think there are some agencies where people even neutral (never mind pro)to Trump have to keep their heads down or get harassed. Strongly suspect this includes EPA, much of Justice and State. Unfortunately while I think most of the Federal bureaucracy is actually Neutral to Trump, I agree that even in Nominally pro-Trump agencies like the Coast Guard or CPB there are cliques of rabid anti-trumpers doing everything they can to sabotage him.
