Among the now well-known cast of creatures involved in the panoramic episode of perfidious sedition known as RussiaGate, Mr. Sussman was a bit-player, an errand boy for the Perkins Coie law firm that did much of Hillary Clinton's dirty work in the 2016 campaign and for the Democratic Party beyond. Mr. Sussman is charged with lying to the FBI in conveying campaign dirt paid-for by Mrs. Clinton to the FBI's general counsel, James Baker, Mr. Sussman's old colleague from the days when he worked as a cyber-security expert at the bureau. He also peddled-around the same material, cooked up by Glenn Simpson's Fusion GPS company and man-of-mystery Christopher Steele, to The New York Times and other news media, who ran with it like kids with a kite.
