"I became aware of an investigation; I am not aware of the extent or the individuals involved. I am, of course, prepared to assist the authorities with any inquiries if requested," Menendez said.
The recently issued subpoenas, including the one sent to Sacco, are not related to any accusations of wrongdoing involving the meat company or Menendez, two sources said.
The sources also noted that the subpoenas partially request information concerning particular legislative modifications in New Jersey. However, they did not provide any specific details regarding the nature of these changes.
The subpoena for Sacco, a Democrat, was released on Wednesday, one day after he was re-elected as the mayor.
Sacco's spokesperson underlined, "We believe it would not be appropriate to make any further comments at this moment."
