I think that DCJ piece is good, and clearly ‘mob’ connections are rife, but outside of that early-80’s wash of Roy Cohn and the ready-mix concrete guys, there’s not a lot more specific to Italian mafia.

I read that Giuliani’s ‘cleanup’ of Italian mobsters allowed in the russians which was duly appreciated. Early 80s is the same time the Kremlin started to keep tabs on Trump, giving him a tour and business opportunities then.

Felix Sater, Michael Cohen, Rybolovlev and others who consistently and repeatedly appear in any honest accounting of his blatantly illegal dealings.

Unger’s account of infiltration also exposes how Trump’s financial entanglements laid the groundwork for this betrayal. In the 1980s, as Trump struggled with debt from failing casinos and overextended real estate ventures, Soviet-linked financiers appeared, flush with cash.

Deals involving Trump Tower properties drew in shadowy buyers connected to Russian organized crime and intelligence fronts. Even when Western banks deemed him too risky, new Russian-linked money never seemed to dry up. Each transaction pulled him closer into Moscow’s orbit.

By the time the Soviet Union collapsed, Russian oligarchs kept the pipeline open, ensuring that Trump’s business empire would survive—and remain beholden to foreign backers whose first loyalty was to the Kremlin. (via)

So while there certainly were ties to Italian mafia, his later business and almost all of his political life is awash in russian mob ties. Given that russia is run by mafias-within-mafias that’s not so surprising, is it.
