The Trump administration has added Colombia to a list of nations failing to cooperate in the drug war for the first time in nearly three decades. But the U.S. also issued a waiver blocking any major aid cut to the staunch ally. The move Monday reflects a decade-long boom in cocaine production in Colombia and a slowdown in coca eradication under President Gustavo Petro’s leftist administration. The U.S. last added Colombia to the list in 1997 when the country’s cartels had infiltrated the highest levels of power. Since 2000, U.S. administrations have sent billions of dollars in aid to Colombia. The cooperation began to unravel a decade ago when a program to spray coca fields with glyphosate was suspended.

President Donald Trump says the U.S. military again targeted a boat allegedly carrying drugs from Venezuela, killing three aboard the vessel. Trump announced the strike in a posting on social media. The strike comes two weeks after another military strike on what the Trump administration says was a drug-carrying speedboat from Venezuela that killed 11. The administration has justified the military action as a necessary escalation to stem the flow of drugs into the United States. But several senators, Democrats and some Republicans, have indicated their dissatisfaction with the administration’s rationale and questioned the legality of the action. There was no immediate comment from the Venezuelan government.

U.S. Defense Secretary Pete Hegseth and Air Force Gen. Dan Caine, chairman of the Joint Chiefs of Staff, have arrived in Puerto Rico as the U.S. steps up its military operations against drug cartels in the Caribbean. The arrival comes more than a week after ships carrying hundreds of U.S. marines deployed to Puerto Rico for a training exercise. Puerto Rico's Gov. Jenniffer González said Hegseth and Caine visited the U.S. territory on Monday to support those participating in the training. The visit comes as the U.S. prepares to deploy 10 F-35 fighter jets to Puerto Rico for operations targeting drug cartels.
