Must be another/different way to describe this guy’s position - there are lots of U. S. Marshals. What made this one so special he rated a news story? Oh! Perhaps without saying so, he was the HEAD HONCHO? Got it. I think!
Had his hands in the cookie jar.
There are 96 US Marshals throughout the country - one for each judicial district. They are all political appointees and usually are gone when a new President is in place.
