Marco Rubio has been an especially vocal critic of Nicolas Maduro, and the Florida senator's public lambasting of the Venezuelan president, as well as other Rubio remarks, apparently ticked off one powerful politician in that country enough that he wanted Rubio killed for it. The Miami Herald reports on a Department of Homeland Security memo sent out last month to various law enforcement agencies that noted an "order to have Senator Rubio assassinated," though it added that the threat was unconfirmed and that there weren't specifics available on the alleged plot. The man supposedly behind the machinations: Diosdado Cabello Rondon, a former army lieutenant believed to now head up Venezuela's security forces.
Cabello Rondon, who has earned the nickname "the Pablo Escobar of Venezuela" for his alleged dealings in drug trafficking, supposedly was "communicating with unspecified Mexican nationals" in the Rubio assassination plot, per Politico, which has seen the memo. In addition to attacking the Venezuelan president on Twitter, Rubio has also specifically gone after Cabello Rondon, with the Miami Herald documenting some of their back-and-forth online (one of Cabello Rondon's nicknames for the senator: "Narco Rubio"). Fox News reports that Rubio, who hasn't yet commented publicly on this development, has been flanked by extra security, including from Capitol Police, since the threat became known.
