This is hardly surprising.
After a two-year investigation federal prosecutors will bring corruption charges against U.S. Senator Robert Menendez from New Jersey for allegedly doing political favors for Florida doctor Salomon Melgen in exchange for generous gifts and campaign contributions as reported by CNN.
Menendez was dubbed "Bully Bob" after warning U.S. Attorney Paul Fishman not to release news concerning a criminal investigation into a top donor during his 2012 re-election bid as reported by Jonathan Dienst for NBC: "several sources describe the call as 'a threat' while others say they would not go that far but describe it as a serious ethical breach."
Apparently the pressure is getting to Menendez, and in recent days has engaged in paranoid rants about shadowy operatives from the Cuban government launching a smear campaign against him involving underage prostitutes in the Dominican Republic as reported by Hadas Gold for Politico.
