Russian metal tycoon Oleg Deripaska filed suit [complaint, PDF] in New York state court Wednesday against former Trump campaign chairman Paul Manafort and associate Rick Gates alleging fraud.

Related charges were brought in 2014 in the Cayman Islands. This new claim relies in part on evidence from the unsealed indictment [text, PDF] against Manafort stemming from Special Counsel Robert Muller’s investigation into possible coordination between the Trump campaign and Russia.

Deripaska, through his company Surf Horizon Limited, gave $18.9 million to Manafort and Gates to invest in an Ukrainian cable network. The lawsuit alleges that the two American lobbyists instead put the money to use financing their lavish lifestyle, buying homes and paying children’s tuition. The Cayman Islands lawsuit had sought to compel production of an account of the funds. Lawyers for Deripaska now use details of the international money laundering scheme alleged by the Special Counsel to account for this money. In their new case of fraud against Manafort and Gates, Surf Horizon Limited seeks nearly $27 million in compensatory and punitive damages.
