WASHINGTON (March 15, 2013)—A federal grand jury in Miami is investigating U.S. Sen. Robert Menendez, D-N.J., for his role in advocating for the business interests of a wealthy donor and friend, the Washington Post reported.
A story on the newspaper's website late Thursday said that as part of the probe federal agents have questioned witnesses about the interactions between Menendez and Florida ophthalmologist Salomon Melgen.
The newspaper cites unidentified people it says are familiar with the probe.
Menendez has raised questions with U.S. officials about the Dominican Republic government's failure to honor a port security contract involving Melgen, and he contacted U.S. health agencies to question their billing practices and policies amid a dispute between Melgen and federal authorities.
The Post says Melgen declined to say Thursday whether he knew anything about the investigation, but he says any probe would find no wrongdoing.
