is the relationship between Miami ophthalmologist Solomon Melgen and New Jersey Senator Robert Menendez:

Melgen had reportedly received help from Menendez is the matter of a port-security contract between a company owned by Melgen and the Dominican government. That contract could be worth as much as $50 million a year for 20 years — that is, a total of one billion dollars — except that Dominican officials refuse to honor what they have condemned as the “exorbitant” terms of the contract. Melgen’s financial situation looks shady; he reportedly owes the IRS $11.1 million. But if he could get the U.S. government to pressure the Dominican Republic into honoring that billion-dollar contract, Melgen’s money worries would be over.

Unfortunately for Melgen, however, Matthew Boyle broke the story less than a week before Election Day last fall and, while the mainstream media ignored Boyle’s exclusive at the time, now the potential political ramifications are quite serious. Even if it cannot be proven that Menendez consorted with hookers, underaged or otherwise, during his visits to Melgen’s Caribbean luxury resort, the New Jersey Democrat’s connection to his Florida benefactor is sure to be subjected to intense scrutiny now.

Let’s hope so.

In Santo Domingo, Vinicio Castillo, Melgen’s and Menendez’s Dominican lawyer – who also happens to be Melgen’s cousin – said the accusations are aimed at discrediting Salomon Melgen and U.S. Sen. Robert Menendez and stopping a contract to X-ray shipments moving through ports in the Dominican Republic.

Castillo called the allegations part of a “diabolical plot” orchestrated to discredit Melgen, who owns a company with a lucrative contract with the Dominican government to provide X-ray machines at ports. The machines would be used to scan shipping containers to look for contraband and illegal drugs.

The contract was originally signed with the Dominican government a decade ago. Two years ago, Melgen bought out the company that had signed the contract.

That contract has raised controversy due to its cost — an estimated $500 million to $1 billion over 20 years. And the machines have not been installed.

Menendez, who has received healthy campaign contributions from the doctor, in a July Senate hearing peppered Obama officials about what they were doing to help U.S. business interests in the Dominican Republic. He specifically mentioned the contract for X-ray equipment at the ports.

Castillo’s father, Vinicio “Vincho” Castillo, the government’s drug czar and Melgen’s uncle, has also spoken about the need for the machines.

Menendez would rather have you believe this is a story that “anonymous, nameless, faceless individuals on a Web site” concocted.
