Sen. Tim Kaine on Monday accused the Trump administration of committing murder with its campaign of military strikes against purported drug trafficking vessels, which has killed at least 221 people since its launch in September 2025.

In a letter sent to President Donald Trump, Kaine (D-Va.) said that he reviewed classified notifications sent to Congress related to the boat strike campaign and concluded that the US “is engaged in violent and fatal attacks against people far beyond those” whom the Department of Justice Office of Legal Counsel (OLC) said would be legitimate military targets.

Kaine didn’t go into detail about the OLC’s classified legal opinion justifying the strikes, but he said the evidence he has gathered suggests the US “has killed individuals who are not involved in narcotrafficking.”

“They are murder victims,” Kaine emphasized.

Kaine also pointed to a recent analysis conducted by the Drug Enforcement Administration, first reported on by The Washington Post last month, which found that the boat strike campaign “has had no effect on the flow of illegal drugs into the United States.”

Kaine concluded his letter by urging Trump to “closely examine the circumstances of these strikes, to ensure that you are personally aware of the extent to which the leadership of the Department of Defense has exceeded your July 2025 directive, incurring massive expense and operating with dubious legality, and with no progress towards your stated objective.”

“And once you have done so,” Kaine added, “I urge you to halt this illegal, costly, and ineffective operation.”

Despite Kaine’s warnings, there is little sign that the administration is rethinking its boat strike campaign.

US Southern Command (SOUTHCOM) on Monday announced the formation of the Joint Task Force Western Hemisphere, a new command structure aimed specifically at combating international drug cartels.

Journalist Juan Esteban Silva described the announcement of the task force as “major shift” in US security strategy that is putting “Colombia and Venezuela… at the center of the conversation.”

An analysis published by The Diplomatic Insight on Tuesday said the SOUTHCOM announcement “aligns with Trump administration’s anti-narcotics campaign under a permanent command structure with expanded geographic reach, part of what the administration has described as a ‘maximum pressure’ policy against transnational criminal networks in the hemisphere.”

The analysis also noted that the new command structure replaces Joint Task Force Southern Spear, which has been responsible for carrying out boat strike operations in the Caribbean and Eastern Pacific Ocean.
