NEW YORK — U.S. Sen. Bob Menendez publicly supported the government of Qatar and enabled a member of the Qatari royal family, a principal in a company with ties to the government of Qatar, to invest tens of millions of dollars in a New Jersey businessman’s real estate project, a rewritten indictment alleged Tuesday.

The superseding indictment in Manhattan federal court did not identify the member of the Qatari royal family but said the individual was the principal of the Qatari Investment Co., an investment fund. Menendez, D-N.J., already was charged with wielding his political influence to secretly advance Egypt’s interests.

The indictment said the Qatari investor eventually negotiated a multimillion-dollar investment finalized in 2023 in the real estate project planned by Fred Daibes, one of three businessmen charged in the indictment along with the 70-year-old senator and his wife. All have pleaded not guilty.

Adam Fee, a lawyer for Menendez, said in a statement that the new allegations “stink of desperation.”

“Despite what they’ve touted in press releases, the government does not have the proof to back up any of the old or new allegations against Senator Menendez. What they have instead is a string of baseless assumptions and bizarre conjectures based on routine, lawful contacts between a Senator and his constituents or foreign officials. They are turning this into a persecution, not a prosecution,” he said.

“At all times, Senator Menendez acted entirely appropriately with respect to Qatar, Egypt, and the many other countries he routinely interacts with. Those interactions were always based on his professional judgment as to the best interests of the United States because he is, and always has been, a patriot. This latest Indictment only exposes the lengths to which these hostile prosecutors will go to poison the public before a trial even begins. But these new allegations don’t change a thing, and their theories won’t survive the scrutiny of the court or a jury,” Fee added.

Tim Donohue, a lawyer for Daibes, said he had no immediate comment.

The indictment contains new details about the relationship between Menendez and Daibes, a powerful New Jersey real estate developer.
