From the Document: "In recent weeks, the Trump Administration has imposed a series of increasingly strong economic sanctions against Cuba, effectively ending the previous policy of engagement begun by the Obama Administration in 2014 that had eased some sanctions and moved toward the normalization of relations. As a result, U.S. policy toward Cuba again is centered on economic pressure aimed at influencing the behavior of the Cuban government, not only with regard to Cuba'sown human rights record, but also its support to the regime of Nicolás Maduro in Venezuela. On April 30, 2019, President Trump threatened a 'full and complete embargo' on Cuba and 'highest-level sanctions' unless Cuba ceased its military support for the Maduro regime. Congress traditionally has played an important role in shaping U.S. policy toward Cuba through legislation and oversight, but has appeared divided over Cuba the past decade, with some favoring engagement and others favoring strong sanctions."
