When federal prosecutors charged a former top FBI agent with violating U.S. sanctions against Russia early in January, an unnamed “international law firm in Manhattan” landed at the center of some of the relationships detailed in the 21-page indictment.

While the indictment unsealed last week against Charles McGonigal does not identify the firm to whom he allegedly introduced an agent for oligarch Oleg Deripaska, with the goal of ending sanctions against the billionaire with close ties to Vladimir Putin, Am Law 200 firm Kobre & Kim has a documented connection to these players, via a 2021 disclosure that names the law firm, along with the defendants.
