U.S. President Donald Trump speaks in the Oval Office of the White House in Washington, DC, March 27, 2019.

U.S. President Donald Trump said on Thursday he is considering a quarantine or blockade of Venezuela, as the United States steps up pressure on President Nicolas Maduro to relinquish power.

Asked by a reporter whether he was considering such a measure given the amount of involvement by China and Iran in Venezuela, Trump said: "Yes, I am."
