Donald Trump’s real estate empire is linked to an international money-laundering scheme that netted more than $1 billion for himself and his business partners, according to the third installment of a documentary series by Dutch filmmakers that aired Wednesday.

As Alternet’s Steven Rosenfeld reports, director of “The Dubious Friends of Donald Trump, Part III: The Multibillion-Dollar Fraud” Sander Rietveld followed the transfer of money from Kazakhstan to the United States to identify “how this could relate to Donald Trump, the Trump Organization and Trump’s real estate.”

The result, Rietveld said, ”is a follow-the-money documentary revealing the connections between several people in Trump’s orbit and an alleged multibillion-dollar fraud.” Rietveld also noted Kazakh oligarch Ilyas Khrapunov “tried to block” the documentary from airing.

“Judge turned down his request and allowed airing documentary,” Rietveld said.

The documentary zeros in on money from Kazakhstan that went towards Bayrock, the group that joined forces with Trump International for the company’s SoHo Tower project. The project manager of Bayrock, Felix Sater, pleaded guilty in 1998 to a fraud scheme involving the Russian mob. He later became an FBI informant and in 2017 began cooperating with investigators working on an international money laundering scheme, the Financial Times reports.

“The significant thing is they have got the Kazakh government saying that Bayrock was a money launderer for these guys,” James Henry, an investigative reporter who worked on the film, told AlterNet. Henry noted if special counsel Robert Mueller probes Trump’s Bayrock ties, “we have Felix Sater laundering criminal money.”

Pointing to the the previous two installments in this documentary series, Henry argued Trump and his associates have engaged in “a continuing cover-up of money laundering.”
