President Donald Trump's administration has increased pressure on Venezuelan President Nicolás Maduro by designating the Cartel de los Soles as a foreign terrorist organization. The move Monday is part of the Trump administration's escalating campaign to combat drug trafficking into the United States. Secretary of State Marco Rubio has accused it of being responsible for terrorist violence in the Western Hemisphere. The term Cartel de los Soles originally referred to Venezuelan military officers involved in drug-running, but it is not a cartel per se. The designation comes as Trump evaluates whether to take military action against Venezuela. The U.S. Justice Department has indicted Maduro on narcoterrorism charges.
