WASHINGTON (AP) — The White House said Monday that a Navy admiral acted “within his authority and the law” when he ordered a second, follow-up strike on an alleged drug boat in the Caribbean Sea in a September U.S. military operation that has come under bipartisan scrutiny.

White House press secretary Karoline Leavitt offered the justification for the Sept. 2 strike as lawmakers announced there will be congressional review of the U.S. military strikes against vessels suspected of smuggling drugs in the Caribbean and the eastern Pacific Ocean. The lawmakers cited a published report that Defense Secretary Pete Hegseth issued a verbal order for a second strike that killed survivors on the boat.

Navy Vice Adm. Frank “Mitch” Bradley, who Leavitt said ordered the second strike, is expected to provide a classified briefing Thursday to lawmakers overseeing the military.

Leavitt in her comments to reporters did not dispute a Washington Post report that there were survivors after the initial strike. Her explanation came after President Donald Trump a day earlier said he “wouldn’t have wanted that — not a second strike” when asked about the incident.

“Secretary Hegseth authorized Admiral Bradley to conduct these kinetic strikes,” said Leavitt. “Admiral Bradley worked well within his authority and the law, directing the engagement to ensure the boat was destroyed and the threat to the United States of America was eliminated.”

Late Monday, Hegseth posted: “Admiral Mitch Bradley is an American hero, a true professional, and has my 100% support. I stand by him and the combat decisions he has made — on the September 2 mission and all others since.”

A month after the strike, Bradley was promoted from commander of Joint Special Operations Command to commander of U.S. Special Operations Command.

Concern over the Trump administration’s military strikes against the alleged drug-smuggling boats has been building in Congress, but details of this follow-on strike stunned many lawmakers from both parties and generated stark questions about the legality of the attacks and the overall strategy in the region, and particularly toward Venezuelan President Nicolás Maduro.

The lawmakers said they did not know whether last week’s Post report was true, and some Republicans were skeptical. Still, they said the reported attacking of survivors of an initial missile strike posed serious concerns and merited further scrutiny.

The White House weighed in after Trump on Sunday vigorously defended Hegseth.

“Pete said he did not order the death of those two men,” Trump said. He added, “And I believe him.”

Leavitt said Hegseth has spoken with members of Congress who may have expressed some concerns about the reports over the weekend.

Gen. Dan Caine, chairman of the Joint Chiefs of Staff, also spoke over the weekend with the two Republican and two Democratic lawmakers leading the Senate and House Armed Services committees. He reiterated “his trust and confidence in the experienced commanders at every echelon,” Caine’s office said in a statement.

The statement added that the call focused on “addressing the intent and legality of missions to disrupt illicit trafficking networks which threaten the security and stability of the Western Hemisphere.”

Senate Majority Leader John Thune on Monday broadly defended the operations, echoing the Trump administration position that they’re necessary to stem the flow of illegal narcotics into the United States.

Thune said the committees in Congress will look into what happened. “I don’t think you want to draw any conclusions or deductions until you have all the facts,” he said of the Sept. 2 strike. “We’ll see where they lead.”
