The heart of the charges is that Menendez advocated for Melgen's personal and business interests in exchange for travel — including at least 20 flights — and political and legal-defense contributions. Melgen is accused of paying for private flights for Menendez and various unnamed guests, and of putting them up in a luxury hotel in Paris and a resort in the Dominican Republic. "The ocean-side community has a marina, three golf courses, thirteen tennis courts, three polo playing fields, equestrian facilities, a 245-acre shooting facility, a spa, beaches, restaurants and a hotel," it says of Casa de Campo, where Melgen had a villa where Menendez allegedly stayed several times. The same day, the indictment says, Melgen and his family donated $40,000 to the New Jersey Democratic State Committee's federal election account and $20,000 to Menendez's legal defense fund. The Food and Drug Administration allows each vial to be used for only one eye of one patient, saying using it on multiple patients or both eyes of one patient increased the risk of infection. The indictment says Menendez spoke with Department of Health and Human Services officials on Menendez's behalf, including attempting to arrange a phone call with the secretary, and also tried to get two other senators to take up the cause.
