Federal prosecutors in New York City have rewritten their indictment against U.S. Sen. Bob Menendez of New Jersey and his wife to charge them with conspiring to have him act as an agent of Egypt and Egyptian officials.

The superseding indictment, filed in Manhattan federal court on Thursday, accuses Menendez of violating the Foreign Agents Registration Act, which requires people to register with the U.S. government if they are acting as “an agent of a foreign principal.” As a member of Congress, Menendez was prohibited from being an agent of a foreign government, even if he did register as one.

The indictment says the conspiracy occurred from January 2018 to June 2022.
