Two survivors of a Sept. 2 U.S. strike on a boat in the Caribbean were killed in follow-up attacks after they were seen still aboard the damaged vessel alongside packages of illegal narcotics, a senior commander is expected to tell lawmakers Thursday. Adm. Frank "Mitch" Bradley plans to say he and his legal adviser concluded the two survivors were attempting to continue their drug run, making them and the already-damaged vessel legitimate targets for another attack, two defense officials said. The details of the strike have emerged as a matter of concern for members of Congress who are seeking more information about the role played by Bradley and Defense Secretary Pete Hegseth and whether aspects of the operation violated laws of war or Pentagon procedures.
