Bob Menendez: Accused of receiving gifts from wealthy ophthalmologist Solomon Mergen in Florida and exchanging political favors. These gifts include traveling abroad on Dr. Mergen's private jet, luxury vacations in Paris and the Caribbean, and campaign donations to organizations that support Menendez. Prosecutors claim that Menendez has become Dr. Mergen's "private senator" and accuse him of using his influence to help Mergen defend a bill dispute related to Medicare.
