This is what a CPO Chief Petty Officer uniform looks like.

This is what a Commissioned Naval Officer uniform looks like.

So, the question is? What country is his uniform from? It is not an American Navy uniform at all, of any kind.
Whether the guy was really actually in the Navy or not, is answering the wrong question.
Maybe he 'made up' his own uniform so he could be on stage with Hillary with it on. This is normally against regulations, but in this case, I don't know. Since this is not a real uniform, does it apply?
