Prosecutors say Melgen bribed Menendez with scores of trips on his private jet, vacations at exclusive Dominican resorts and the high-end Paris hotel, and hundreds of thousands of dollars in campaign contributions. Although the senator didn't pay for the trips at the time – or report them on his financial-disclosure forms – he did aid Melgen in another way, prosecutors say: by using the power of his office to help the doctor's foreign girlfriends obtain visas and pressuring high-level government officials to change policies ranging from Medicare reimbursement to Dominican port security that would advance the doctor's financial interests.
