Sen. Bob Menendez used his influence to advocate for a Dominican Republic business deal that helped a longtime friend and donor whose South Florida office was raided by federal agents this week.

Menendez questioned Obama administration officials at a July hearing about what it was doing to help U.S. businesses that he felt were being unfairly treated by the government of the Dominican Republic and other Latin American countries.

One company Menendez was apparently referring to: ICSSI, acquired the year before by Dr. Salomon Melgen, a Palm Beach County eye doctor and friend. The firm was seeking to enforce a contract it had won to X-ray Dominican Republic port cargo, that could be worth $500 million to $1 billion over two decades.
