State of the Irish Mob in America

I was wondering if there is any indication that there is still an Irish Mob alive in America? I know NYC had gangs like the Westies up through the 80s. And Boston was known for gangs like Whitey Bulger's. Is there any known or powerful Irish Mob's still around?
Also, is there any good historical reading online about them? I did a search on the forum here and did not come across a ton of information.

Probably the main books would be the two by Tj English, westies and paddywacked

But those are books

Thanks. I have read The Westies. I will check out Paddywhacked.
