Sen. Bob Menendez, his wife Nadine and an Egyptian-born New Jersey businessman have been charged with an additional count of conspiracy for a public official to act as a foreign agent in a superseding indictment handed up Thursday.

The 69-year-old New Jersey Democrat now faces four counts in a case brought by Manhattan prosecutors accusing him of accepting cash, gold, a luxury car and other items in exchange for using his influence to help Wael Hana and two other cronies.

The new count formally accuses Menendez of surreptitiously lobbying his colleagues while chair of the powerful Senate Foreign Relations Committee, to unfreeze $300 million in military aid meant for the Cairo government.
