Clinton signs the Helms-Burton Act, codifying the Cuba embargo into law

President Bill Clinton signed the Cuban Liberty and Democratic Solidarity Act — known as the Helms-Burton Act — on March 12, 1996, at a ceremony attended by families of the four men killed in the Brothers to the Rescue shootdown. The legislation, which Clinton had previously threatened to veto, was fast-tracked through Congress after the shootdown gave it overwhelming bipartisan momentum. Helms-Burton codified the existing executive-order-based Cuba embargo into statute, making it far harder for future presidents to lift sanctions unilaterally, and created new provisions allowing U.S. nationals to sue foreign companies that "traffic" in property confiscated by Cuba. The act fundamentally shifted Cuba policy from presidential discretion to congressional mandate.
