Sheriffs are not politically appointed, they do not work for the governor, they are elected by and answer directly to the people who elected them in the county for which they serve.
Last week, as I recall, Inslee threatened to arrest the Sheriffs for not enforcing state law.
The Attorney General of Washington state is an independently elected Democrat, so I assume that Inslee and the A.G. are rowing on the same boat.
By the way, Inslee and the A.G. do not enforce immigration law in Washington!
