Not that I know of, but I guess elements of the USCG can be seconded by the USN to assist in a law-enforcement capacity? it makes sense that the maritime forces get to play together though.
Navy has vastly more maritime resources than the USCG and will pass info, but doesn't board ships or engage in pursuit on it's own.
It's actually a good system, as the difference between Defense and LE is important to maintain.
The movie Sicario is basically premised off this idea of getting a LE Officer onboard for legality’s sake.
