Trump orders unilateral "complete blockade" of sanctioned oil tankers off Venezuela
On December 16, 2025, President Trump announced via Truth Social that he had ordered a "complete blockade" of all U.S.-sanctioned oil tankers going to and from Venezuela, declaring the country "completely surrounded by the largest Armada ever assembled in the History of South America." The unilateral order — issued without congressional authorization — became the operational basis for a wave of Coast Guard tanker seizures and interdictions off Venezuela in the days and weeks that followed.
