The Nazis party required a loyalty oath, not to the law, or the people or to their Constitution but to the all powerful Leader Adolph.  Holding any type of civil service job in Nazis Germany required membership in the Nazis party.  Here we take an oath when entering the service, we swear to defend the US Constitution against all enemies foreign and domestic.  Zinke, Trump and the entire ilk associated with Trump are a domestic threat to our Constitution and needed to be regarded accordingly.
