In 2013, the Justice Department filed an asset-forfeiture lawsuit that was sensitive because it focused on Russian corruption. It arose out of a $230 million fraud orchestrated by the Putin regime, and involved the detention, torture, and murder of Sergei Magnitsky, the Russian investigator who exposed the scheme. (I will have more to say about the case in a subsequent column.) At the center of the case was Veselnitskaya’s client, Denis Katsyv.
