The Justice Department will reportedly file corruption charges against Senator Bob Menendez in the upcoming weeks, according to CNN. The expected charges stemmed from an investigation of the New Jersey Democrat’s relationship with Florida ophthalmologist Salomon Melgen, a longtime donor and friend of the senator and his family. Menendez has called the investigation, which involved the DOJ and the FBI, a “smear campaign.” After the federal investigation began in 2013, Menendez paid Melgen $58,000 for flights he took on the donor’s private plane to the Dominican Republic. The investigation has involved several other possible instances of corruption. Given the statute of limitations on several of the potential charges, CNN reports that charges will be announced soon.
