WASHINGTON (AP) — Special counsel Robert Mueller’s grand jury is investigating a prominent Democratic lobbyist and a former GOP congressman for their involvement in an influence campaign on behalf of Ukrainian interests tied to Paul Manafort, according to a person with direct knowledge of the investigation. At the center of the widening probe are Tony Podesta, a longtime Democratic operative, and Vin Weber, a former GOP congressman and leader of his own high-powered lobbying firm, Mercury LLC. The two men were hired as part of a multimillion-dollar lobbying effort directed by Manafort and longtime associate Rick Gates.
