Last week, ostensibly in the name of “transparency,” Donald Trump Jr. published a series of e-mails he exchanged last year with Rob Goldstone, an intermediary who was hoping to arrange a meeting between the Trump campaign and a Kremlin-connected lawyer whom, he promised, would deliver compromising information about Hillary Clinton as part of a Russian government plot to help his father win the presidency. (Junior’s infamous response: “If it's what you say I love it especially later in the summer.”) Since then, a series of follow-up reports have shown that the White House’s effort at transparency was anything but. Over the past several days, we’ve learned that in addition to Trump Jr., Jared Kushner, Paul Manafort, and Goldstone, a music public relations executive with long ties to the Trumps, the June 9 meeting with attorney Natalia Veselnitskaya at Trump Tower was also attended by Rinat Akhmetshin, an alleged ex-Soviet spy turned Russian-American lobbyist and Anatoli Samachornov, who was reportedly there as a translator for Veselnitskaya, bringing the total number to seven.

The day the scandal broke, Trump Jr. recorded an interview with Sean Hannity in order to put the matter to rest. “I just want the truth to get out there. And that’s part of why I released all the stuff today,” he told Hannity. “This is everything.” Now, it turns out there was an eighth participant at the Trump Tower meeting, too. And if you thought the alleged ex-Soviet spy was bad, wait until you read about Irakly “Ike” Kaveladze.

Kaveladze’s lawyer, Scott Balber, who confirmed his client’s identity to CNN on Tuesday, said that Kaveladze attended the meeting “just to make sure it happened and to serve as an interpreter if necessary.” (Kaveladze was apparently unaware that Veselnitskaya had brought her own interpreter.) Kaveladze is a senior vice president at Crocus Group, the real-estate development firm owned by Aras Agalarov, the Russian oligarch and real-estate developer who, Goldstone told Trump Jr. in their e-mail exchange, had dirt on Clinton. (Goldstone represents Agalarov’s son, Emin Agalarov, a Russian pop star who was involved, along with his father, in bringing Trump’s Miss Universe pageant to Moscow in 2013.) But it’s Kaveladze’s previous work experience that may be of particular interest to people like special counsel Robert Mueller.

Kaveladze reportedly began working for Agalarov in the early 1990s, around which time federal investigators believe he began laundering money. According to an October 2000 report from the Government Accountability Office, Kaveladze was a central figure in a near decade-long effort to launder $1.4 billion of Russian and Eastern European money through U.S. banks. The report, which was flagged by ThinkProgress’s Judd Legum, alleges that “more than $800 million was deposited through wire transfer transactions from foreign countries into IBC/Euro-American client accounts at Citibank. Over 70 percent of these deposits was subsequently moved out of the U.S. banking system through wire transfer transactions to accounts in foreign countries. According to a Citibank official, these deposits included funds from Russia; and Citibank no longer opens accounts for clients of IBC/Euro-American because of concerns over suspicious account activity.”

While the G.A.O. doesn’t identify Kaveladze by name, Legum notes a November 2000 New York Times article that flags him as the person who “set up more than 2,000 corporations in Delaware for Russian brokers and then opened . . . banks accounts for them” at Citibank and the Commercial Bank of San Francisco. The same article concludes that the money “was highly likely to have arisen from Russian executives who were seeking to avoid taxes, although some money could be from organized crime.” (Kaveladze has denied all accusations of wrongdoing, and described the G.A.O. investigation at the time as a “witch hunt.”) Citibank later closed all the accounts opened by Kaveladze, and Commercial Bank shuttered its international banking division.
