U.S. Defence Secretary Pete Hegseth said Tuesday that the Pentagon will not publicly release unedited video of a strike that killed two survivors of an initial attack on a boat allegedly carrying cocaine in the Caribbean.

Hegseth said that members of the U.S. House and Senate armed services committees would have an opportunity this week to review the video, but did not say whether all members of Congress would be allowed to see it, even as a defence policy bill demands that it be released to Congress.

“Of course we’re not going to release a top secret, full, unedited video of that to the general public,” Hegseth told reporters as he exited a closed-door briefing with senators.

U.S. President Donald Trump’s top cabinet officials overseeing national security were on Capitol Hill Tuesday to defend the swift escalation of U.S. military force and deadly boat strikes in international waters near Venezuela, but it left lawmakers questioning the broader goals of the campaign.

Democrats left the Senate briefing saying it had been too short and that the officials from Trump’s administration had not seemed prepared to thoroughly answer questions.

“The administration came to this briefing empty-handed,” Senate Democratic Leader Chuck Schumer said. “We don’t know what the ultimate goal is. The president says different things at different times and contradicts himself.”

Hegseth, along with U.S. Secretary of State Marco Rubio and others, briefed the House and the Senate amid congressional investigations into the military strike in September that killed two survivors. Overall, they defended the campaign as a success that had prevented drugs from reaching American shores.

Rubio told reporters the campaign is a “counter drug mission” that is “focused on dismantling the infrastructure of these terrorist organizations that are operating in our hemisphere, undermining the security of Americans, killing Americans, poisoning Americans.”

But lawmakers have been focusing on the Sept. 2 attack on two survivors as they sift through the rationale for the broader U.S. military buildup in the region that increasingly appears pointed at Venezuela. On the eve of the briefings, the U.S. military said late Monday it attacked three more boats believed to have been smuggling drugs in the eastern Pacific Ocean, killing eight people.

Senators on both sides of the aisle said the officials left them in the dark about Trump’s goals when it comes to Venezuelan President Nicolás Maduro or committing U.S. forces directly to the South American nation.

The closed-door sessions come as the U.S. is building up warships, flying fighter jets near Venezuelan airspace and seizing an oil tanker as part of its campaign against Maduro, who has insisted the real purpose of the U.S. military operations is to force him from office.

Trump’s Republican administration has not sought any authorization from Congress for action against Venezuela. But lawmakers objecting to the military incursions are pushing war powers resolutions toward potential voting this week.

‘You’re shooting civilians’

It’s all raising sharp questions that Hegseth and the others will be pressed to answer. The administration’s go-it-alone approach without Congress, experts say, has led to problematic military actions, none more so than the strike that killed two people who had climbed on top of part of a boat that had been partially destroyed in an initial attack.

“If it’s not a war against Venezuela, then we’re using armed force against civilians who are just committing crimes,” said John Yoo, a Berkeley Law professor who helped craft the George W. Bush administration’s legal arguments and justification for aggressive interrogation after the Sept. 11, 2001, attacks. “Then this question, this worry, becomes really pronounced. You know, you’re shooting civilians. There’s no military purpose for it.”

Yet for the first several months, Congress has received little more than a trickle of information about why or how the U.S. military was conducting a campaign that has destroyed more than 20 boats and killed at least 95 people. At times, lawmakers have learned of strikes from social media after the Pentagon posted videos of boats bursting into flames.

Congress is now demanding — including with language in an annual military policy bill — that the Pentagon release video of that initial operation to lawmakers.

For some, the footage has become a case sample that demonstrates the flawed rationale behind the entire campaign.

“The American public ought to see it. I think shooting unarmed people floundering in the water, clinging to wreckage, is not who we are as a people,” said Sen. Rand Paul, a Republican who has been an outspoken critic of the campaign. “You can’t say you’re at war and say, ‘We’re not going to give any kind of due process to anybody and blow up people without any kind of proof,'” he said.

Hegseth told lawmakers last week that he was still deciding whether to release the footage.

Still, there are also many prominent Republicans who back the campaign. Sen. Jim Risch, the Republican chair of the Senate foreign relations committee, last week called the attacks “absolutely, totally, and 100 per cent legal under U.S. law and international law” and claimed that many American lives had been saved by making sure the drugs didn’t reach the U.S.

But as lawmakers have dug into the details of the Sept. 2 strike, inconsistencies have emerged in the Trump administration’s explanation of the attack, which the Pentagon initially tried to dismiss as a “completely false” narrative.

Shifting rationale

Trump has argued the strike that killed survivors was justified because the people were trying to overturn the boat. Several Republican lawmakers have also put forward that argument, saying that it showed the two survivors were trying to stay in the fight, rather than surrender.

However, Adm. Frank (Mitch) Bradley, who ordered the second strike as he commanded the special forces soldiers conducting it, acknowledged in private briefings on Capitol Hill last week that although the two people had tried to overturn the boat, they were unlikely to succeed. That’s according to several people who either were in the briefings or had knowledge of them and spoke on the condition of anonymity because they were not authorized to discuss them.

The two people had climbed on top of the overturned boat, had not made any radio or cellphone calls for backup and were waving, Bradley told the lawmakers. The navy admiral consulted with a military attorney, then ordered the second strike because it was believed that drugs were in the hull of the boat and the mission was to make sure they were destroyed.

Were the survivors ‘shipwrecked’?

Experts say the strike seems to run counter to the Pentagon’s own manual on the laws of war, which states that “orders to fire upon the shipwrecked would be clearly illegal.”

“The boat was damaged, the boat was overturned, and the boat had no power,” said Michael Schmitt, a former U.S. air force lawyer and professor emeritus at the U.S. Naval War College. “I really don’t care if there was another boat coming to rescue them. They’re shipwrecked.”

The argument at the heart of Trump’s campaign — that drugs bound for the U.S. are the equivalent of an attack on American lives — has resulted in lawmakers trying to parse whether laws were violated and, more broadly, what Trump’s goals are with Venezuela.

Besides the briefings from Hegseth and Rubio on Tuesday, Bradley is also expected to appear for classified briefings with the Senate and House armed services committees on Wednesday.

Republican Sen. Thom Tillis said he wants to “really understand what action, what intelligence they were acting on and whether or not they follow the laws of war, the laws of the sea.”
