Democratic Sen Bob Menendez's wife enters plea in bribery case as questions swirl

Sen. Bob Menendez's wife and three other alleged co-conspirators accused in a complex bribery scheme with the New Jersey Democrat pleaded not guilty in federal court Wednesday.

Nadine Menendez, along with Wael Hana, Jose Uribe and Fred Daibes, pleaded not guilty in a federal courtroom in New York, NorthJersey.com reported. 

It was the second time the co-defendants appeared in court after prosecutors filed a superseding indictment last week that charged Sen. Menendez, D-N.J.; his wife; and Hana, a New Jersey businessman from Egypt, with conspiracy for a public official to act as an agent of a foreign principal.
