 Sen. Marco Rubio engaged in a Sunday morning Twitter war with one of his favorite targets, Venezuelan ruling socialist party deputy Diosdado Cabello. 
  
 It began after Cabello announced government forces had gotten an apparent military rebellion under control -- before the military or Venezuela's defense minister weighed in. Rubio referred to allegations of drug trafficking that have long hounded Cabello. 
  
 Fact that Narco leader @dcabellor annouced #6Aug military rebellion & govt response shows who's in charge of security forces in #Venezuela — Marco Rubio (@marcorubio) August 6, 2017 
  
 Cabello responded by suggesting Rubio -- read: the U.S. -- might be behind the "terrorist attack," given that Rubio was the first foreign official to comment on the short-lived insurrection. 
  
 El primer personaje que sale a defender el ataque terrorista es @marcorubio, ya sabemos de dónde viene todo, serás derrotado una y mil veces — Diosdado Cabello R (@dcabellor) August 6, 2017 
  
 He then dubbed the Florida Republican "Narco Rubio."

Marco Rubio, a fervent critic of the South American country’s government, according to intelligence obtained by the U.S. last month. 
  
 Although federal authorities couldn’t be sure at the time whether the uncorroborated threat was real, they took it seriously enough that Rubio has been guarded by a security detail for several weeks in both Washington and Miami. 
  
 Believed to be behind the order: Diosdado Cabello, the influential former military chief and lawmaker from the ruling socialist party who has publicly feuded with Rubio. 
  
 At a July 19 Senate hearing, the same day he was first spotted with more security, Rubio repeated his line that Cabello — who has long been suspected by U.S. authorities of drug trafficking — is “the Pablo Escobar of Venezuela.” A week ago on Twitter, Cabello dubbed the senator “Narco Rubio.”

 The death threat was outlined in a memo to several law enforcement agencies disseminated last month by the Department of Homeland Security. The memo, designated “law enforcement sensitive” but not classified, was obtained by the Miami Herald. 
  
 The memo revealed an “order to have Senator Rubio assassinated,” though it also warned that “no specific information regarding an assassination plot against Senator Rubio has been garnered thus far” and that the U.S. had not been able to verify the threat. That Cabello has been a vocal Rubio critic in Venezuelan media was also noted, a sign that federal authorities are well aware of the political bluster complicating the situation. 
  
 According to the memo, Cabello might have gone as far as to contact “unspecified Mexican nationals” in connection with his plan to harm Rubio. 
  
 The U.S. believes Cabello controls all of Venezuela’s security forces. Rubio, a Republican, has President Donald Trump’s ear on U.S. policy toward Venezuela.

 The Venezuelan Embassy in Washington declined to comment Saturday. Venezuela’s Ministry of Communication and Information said Sunday that it could not respond to media queries until Monday. Messages sent to some of Cabello’s email addresses were not immediately returned. 
  
 Rubio declined comment through a spokeswoman. His office had previously sent reporters’ questions about the security detail to Capitol Police, which did not respond Saturday but has in the past also declined comment. 
  
 Capitol Police “is responsible for the security of members of Congress,” Homeland Security spokesman David Lapan said in a statement. “It would be inappropriate for DHS to comment on the seriousness of the threat.” 
  
 Lawmakers have been on heightened alert since a June 14 shooting in Virginia targeted Republican members of Congress practicing baseball. House Majority Whip Steve Scalise of Louisiana was critically injured. He was protected by Capitol Police officers — who ultimately killed the shooter — only because he is a member of congressional leadership. 
  
 Capitol reporters first noticed police officers trailing Rubio almost a month ago. When he was interviewed last week by Herald news partner WFOR-CBS 4, Rubio’s security included at least one Miami-Dade County Police officer. MDPD was one of the law-enforcement agencies asked to help protect Rubio. 
  
 Rubio, 46, has led the push for a robust U.S. response against Venezuelan President Nicolás Maduro’s government before and after a disputed July 30 vote that elected a new legislative body whose powers supersede all other government branches — including the opposition-held parliament. Rubio has publicly warned Maduro to beware of people in his inner circle who might be looking to betray him. 
  
 The White House was succeeding in creating a regional coalition to pressure Maduro until Trump said offhandedly Friday that a “military option” in Venezuela remained possible, despite little to no support in the U.S., Venezuela or Latin America for such intervention. 
  
 “We’re not surprised by threats from the empire, from its chief Trump,” Cabello wrote Saturday on Twitter. “In the face of such deranged imperial threats, each person should man their trench. Mine will be next to the people defending the fatherland!” 
  
 For years, U.S. authorities have investigated Cabello and other high-ranking Venezuelan government members for suspected drug smuggling, an allegation Cabello has fiercely denied. Earlier this year, the U.S. accused Vice President Tareck El Aissami of being a drug kingpin and later revealed that he had at least $500 million in illicit funds tucked overseas. 
  
 Cabello, 54, is a former army lieutenant who was close to the late President Hugo Chávez and fought alongside him in a failed 1992 coup. A former vice president and head of parliament, Cabello is now a delegate to the new all-powerful constituent assembly. He continues to exert vast influence over the ruling United Socialist Party of Venezuela. 
  
 Cabello is not, however, among the 30 Venezuelan officials — including Maduro himself — whom the Trump administration has recently placed under financial sanctions for undermining democracy, engaging in corruption and repressing dissent.

 As Marco Rubio helped ratchet up U.S. pressure on Venezuela, a top politician believed to control that country’s security forces began actively discussing a plot to kill the Florida senator last month and may have wanted to use Mexican nationals for the assassination plot, according to a Department of Homeland Security memo sent to state and local law enforcement. 
  
 The alleged threats from the Venezuelan politician, Diosdado Cabello Rondon, were not specific and weren’t corroborated by enough sources to merit a detailed explanation, according to the memo, but the situation was worrying enough to prompt Capitol Police and law enforcement in Miami-Dade County to provide security for Rubio. 
  
 Story Continued Below 
  
 The Miami Herald first reported details of the memo Sunday. 
  
 Despite the potential threat, Rubio has continued to speak out against Venezuelan strongman Nicolas Maduro, has pushed for more sanctions and even engaged in a brief Twitter exchange with Cabello Rondon last week when the senator accused the Venezuelan official of involvement in drug trafficking, which Cabello Rondon has denied. 
  
 “In some unspecified manner, CABELLO RONDON’s problems involved U.S. Senator Marco Rubio,” said the memo, obtained by POLITICO, which is not releasing information that could endanger Rubio, his family or confidential law enforcement methods or sources. 
  
 The memo said that Cabello Rondon may even have discussed raising the money to kill Rubio or deal with the “problems” facing Venezuela’s ruling regime. 
  
 “CABELLO RONDON did indeed issue an order ... to have Senator Rubio assassinated,” the memo said. “Additionally, CABELLO RONDON was communicating with unspecified Mexican nationals in furtherance of the matter.”

 As Venezuela descended into chaos and a fraud-marred election that enabled Maduro to seize power, the United States labeled him a dictator and slapped individual sanctions on him and other members of his regime. 
  
 After a military uprising against Maduro was quashed, Rubio on Aug. 6 called out Cabello Rondon on Twitter and said the incident “shows who's in charge of security forces in #Venezuela.” 
  
 Cabello Rondon replied in Spanish by accusing Rubio of imperialism and as “the defender of the terrorists who attacked Fort Paramacay,” a Venezuelan military base attacked earlier this month, apparently by dissident security forces. 
  
 He also called Rubio “Narco Rubio” — an ironic nickname considering that Cabello Rondon has long been suspected by the United States of involvement in drug trafficking, which he has denied. 
  
 “Diosdado ‘Pablo Escobar’ Cabello is unusually nervous and frantic this morning,” Rubio replied at the time.

A: 
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.
