The Trump administration is reportedly exploring naming Venezuela as a state sponsor of terrora designation that only four countries now hold.
The list is reserved for governments accused of repeatedly providing "support for acts of worldwide terrorism" and includes only Iran, North Korea, Sudan and Syria, The Washington Post reported on Monday.
Rubio and two other Republican senators sent a letter to Secretary of State Mike Pompeo in September urging him to name Venezuela a state sponsor of terrorism and accusing it of links to Lebanon's Hezbollah militant group and the Revolutionary Armed Forces of Colombia, or FARC, but they offered no proof.
In addition, the designation would also help the Nicolás Maduro government to blame the country's woes on the USA, as he has done in the past. Trump has repeatedly broached the subject of military intervention in Venezuela - and designating it as a terrorism sponsor could potentially be a step towards just that.
Despite the fact that no evidence of the involvement of Caracas to the global terrorist activities of Washington has not provided the White House plans to block this Latin American country "in its boundary limits".
Administration officials have long said that further measures were under consideration, including an embargo on Venezuelan oil.
The U.S. piled sanctions on Venezuela earlier this month, adding to the country's economic woes. Once one of the richest countries in South America, the Bolivarian Republic over the last three years going through a deep crisis.
"Venezuelans' exodus is a humanitarian crisis, and the uncontrolled enhancement of this exodus started in 2016", Marcos Hernandez, the coordinator of the research, said, as quoted by El Nacional.
