US Senator Bob Menendez pleaded not guilty to a new federal charge that he conspired with his wife and a businessman to act as an agent of Egypt while he was chairman of the Senate Foreign Relations Committee.

The New Jersey Democrat entered his plea Monday in New York federal court to a revised indictment that includes the foreign agent count as well as earlier charges that he and his wife, Nadine, accepted bribes of cash, gold bars and a Mercedes convertible. In exchange, prosecutors allege, Menendez corruptly helped Egypt and three New Jersey businessmen.
