Several U.S. statutes currently in effect constrain the ability of President Barack Obama—acting alone without Congress—to further substantially ease or lift the current U.S. embargo against Cuba.
Congress specifically enacted sanctions on Cuba through provisions in such legislation as the Cuban Democracy Act of 1992 (CDA, P.L. 102-484, Title XVII), the Cuban Liberty and Democratic Solidarity (LIBERTAD) Act of 1996 (P.L. 104-114), and the Trade Sanctions Reform and Export Enhancement Act of 2000 (TSRA, P.L. 106-387, Title IX).
