As Congress continues pressing the Trump administration for legal justification behind its expanding use of military force, new scrutiny is centering on a maritime strike campaign in the Caribbean and eastern Pacific. On Monday, Aug. 3, Sen. Tim Kaine of Virginia said people killed in those operations were “murder victims” in a letter to President Donald Trump after what he described as a review of classified information. The dispute adds to a months-long fight over whether the administration can treat suspected drug-trafficking boats as military targets without a vote from Congress.
Kaine escalates criticism after classified review
Kaine, a Virginia Democrat who sits on the Senate Armed Services and Foreign Relations committees, told Trump in a letter dated Monday, Aug. 3, that “they are murder victims” after reviewing classified information tied to the administration’s boat-strike campaign, according to CNN’s reporting on the letter. CNN reported that Kaine wrote the United States was carrying out “violent and fatal attacks against people far beyond” the limits of the classified legal opinion he reviewed, and that available evidence suggested some of those killed were not involved in narcotrafficking.
The campaign at issue is known as Operation Southern Spear. According to CNN and a new report from the Washington Office on Latin America, the operation has killed at least 221 people and destroyed at least 67 vessels since it began in September 2025. WOLA said its count was compiled from publicly documented strike events and described the operation as a lethal campaign against civilian boats in Latin America and the Caribbean.
Kaine’s letter marks one of the sharpest statements yet from a senator who has had access to classified material about the strikes. Earlier oversight letters he led in September 2025 asked Trump to explain who was targeted, whether those on board posed an imminent threat, and why interdiction, seizure and arrest were not used instead of lethal force, according to Kaine’s Senate office.
The direct geography in this development is Virginia because Kaine represents the state and is one of the Senate Democrats most publicly challenging the operation. What is confirmed is that Kaine authored the Aug. 3 letter and tied his criticism to a review of classified information shared with Congress, according to CNN’s account and his prior committee work on the issue. What is not yet public is the full classified record he reviewed, and the administration has not released the legal opinion or the underlying targeting evidence for public inspection.
Virginia is also central because Kaine has repeatedly used his committee positions to question the operation’s legal basis. In a June 2 Senate Foreign Relations Committee hearing, Kaine said the administration had still not provided Congress with the Justice Department’s Office of Legal Counsel opinion justifying related uses of force and separately pressed Secretary of State Marco Rubio on targeting criteria for the boat strikes, according to Kaine’s office.
There is no public indication that any Virginia site was struck or that Virginia residents were among the victims discussed in Kaine’s latest letter. The local impact instead runs through representation and oversight: a Virginia senator is directly challenging whether U.S. military force is being used lawfully in operations that the White House says are aimed at narcotics trafficking abroad.
The immediate context for Kaine’s letter is a long-running dispute over whether the president can classify suspected traffickers as wartime enemies and order military strikes at sea. Senate Judiciary Committee Democrats said in an earlier letter to Attorney General Pam Bondi that strikes between Sept. 2 and Oct. 28, 2025, killed 57 people across 14 vessels, and they wrote that summarily killing criminal suspects is prohibited under domestic and international law. That letter also said the administration had relied on a classified Office of Legal Counsel opinion to justify the attacks.
Kaine and other senators have been raising similar questions since the first widely scrutinized strike on Sept. 2, 2025, when a vessel in the Caribbean was hit and 11 people were reportedly killed, according to letters released by Kaine, Sen. Angus King and other lawmakers. Those senators asked whether the people on board had been positively identified as lawful targets, whether they posed an imminent threat, and whether nonlethal options had been considered before force was used.
For residents trying to understand what comes next, the practical reality is that the legal and political fight is still unresolved. The White House has defended the campaign, with spokesperson Anna Kelly telling CNN that the strikes have targeted designated “narcoterrorists” and that Trump will continue using U.S. power against drug trafficking networks. As of Aug. 4, the administration had not publicly released the classified legal opinion that Kaine says he reviewed, leaving the central justification for the operation undisclosed.
