Did you mean this Menendez?:
Relationship with non-profit group
In early September 2006, federal authorities delivered a subpoena to the North Hudson County Action Corp., a non-profit organization in Union City, NJ. Specifically, they sought records of a rental deal between the agency and Menendez.
In 1983, Menendez purchased a three-story brick house on a residential street in Union City for $92,000. He and his family lived there briefly, but ultimately moved out and began renting it as a commercial property. In 1994, he entered a rental agreement with the North Hudson group, who planned to use the home for administrative offices. Menendez charged them $3,100 per month, and later raised the figure to $4,000 per month.
During a nine-year period in which he served Hudson County in the House, Menendez received over $300,000 from the group in rent payments. As a congressman, Menendez often helped secure funds for the non-profit organization. In 1998, Menendez helped the agency win designation as a federally qualified health care center, a title that made it eligible for federal health care grants. In the eight years that followed this designation, the agency collected $9.6 million in federal grants. In 2001, the group honored Menendez as it’s “man of the year” and named a pavilion after him.
Menendez argued that before renting out the house in 1994, he obtained clearance from the House Ethics Committee. He has stated that there was nothing improper about his actions because he never negotiated directly with agency officials and the organization paid slightly below-market rent for the house. In 2003, Menendez sold the house for $450,000. The new owner continued to rent the house to the North Hudson Community Action Corp.; at a rate of $3,700 per month.  
Hiring controversy with top advisor
In September of 2006, a tape emerged of Donald Scarinci - Menendez's chilhood friend and closest political advisor - pressuring a Union City, NJ psychiatrist with several contracts with the prison system to hire an additional physician known to Scarinci. In the secretly recorded conversation, Scarinci told the physician that doing so would be a favor to Menendez, then a member of the U.S. House of Representatives. When the tapes content became public, Menendez severed ties with Scarinci, claiming that he had used his name and influence without his knowledge and committed a serious breach of good judgment.
