From the Document: "Since April 2019, 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 Cuban government's behavior with regard to not only Cuba's human rights record but also its support to the Venezuelan regime of Nicolás Maduro. Congress traditionally has played an important role in shaping U.S. policy toward Cuba through legislation and oversight, but it has appeared divided over Cuba the past decade, with some favoring engagement and others favoring strong sanctions."
