His wife, Nadine Menendez, and two businessmen also have pleaded not guilty. On Friday, one businessman facing charges pled guilty in a cooperation deal with prosecutors that calls for him to testify at any trial.
The trial of Menendez and others is scheduled for May. Lawyers for Menendez did not immediately comment on Stein’s ruling.
A spokesperson for prosecutors declined to comment.
In his ruling, Stein wrote that affidavits supporting requests for search warrants only needed to establish probable cause that searches would turn up “evidence, fruits, or instrumentalities of a crime.”
He said that threshold was “amply satisfied” by evidence described in the affidavit, including numerous messages between Menendez, his wife and one of the businessmen discussing various services and payments that were to be made to Nadine Menendez in return for the senator’s aid to the businessmen.
According to an indictment, Menendez and his wife accepted gold bars and cash from a real estate developer in return for the senator using his clout to get that businessman a multimillion-dollar deal with a Qatari investment fund.
Menendez also was charged with helping another New Jersey business associate get a lucrative deal with the government of Egypt.
