Sen. Bob Menendez (D-N.J.) plans to resign effective Aug. 20, according to two people briefed on the decision, who spoke on the condition of anonymity to discuss internal deliberations. The longtime Democratic lawmaker was convicted on July 16 of taking bribes from three businessmen who showered him and his wife with cash, gold bars and a Mercedes-Benz, an extravagant bounty for his help securing deals with foreign officials and trying to derail several criminal investigations in New Jersey.
