As a pro-democracy activist who is highly concerned with foreign influence-peddling in the United States, I have been closely watching the prosecution of former FBI counterintelligence chief Charles McGonigal. As the Aug. 16 news article “Former senior FBI official pleads guilty to illegally assisting Putin ally” reported, Mr. McGonigal pleaded guilty to charges related to his work for the sanctioned Russian billionaire and Putin ally Oleg Deripaska and, according to Mr. McGonigal’s attorney, is in discussions about another plea deal around allegedly taking bribes while serving as counterintelligence chief of the FBI’s New York bureau.
