Florida's U.S. senators are increasing pressure on the Trump administration to act on the crisis in Venezuela, calling it a national security matter.
After a Friday discussion with Venezuelan, Cuban and Nicaraguan exiles, Republican Sens. Rick Scott and Marco Rubio chastised Cuba for aiding socialist president Nicolas Maduro in a standoff with U.S.-backed opposition leader Juan Guaidó.
The Cuban government denies accusations that it has troops in Venezuela.
The U.S. and more than 50 nations view Maduro's re-election last year as illegitimate because of fraud.
