The son-in-law of Russian oligarch German Khan has been charged with making false statements to the FBI as part of Special Counsel Robert Mueller’s probe of Russian collusion in the 2016 presidential election.

Alex Van Der Zwaan was charged Feb. 16 in federal court in Washington related to a report he helped prepare on the trial of a Ukrainian politician, Yulia Tymoshenko. Van Der Zwaan was charged with a criminal information, which typically precedes a guilty plea.

Van Der Zwaan, identified on his LinkedIn page as an associate in the London office of Skadden, Arps, Slate Meagher & Flom, was questioned regarding the firm’s work in 2012 on behalf of the Ukraine Ministry of Justice.

Van Der Zwaan is also married to Eva Khan, the daughter of Russian oligarch German Khan, who last year sued the media outlet BuzzFeed for libel for publishing the "Trump Dossier."
