President Donald Trump said Wednesday that the United States has seized an oil tanker off the coast of Venezuela as tensions mount with the government of President Nicolás Maduro.

Using U.S. forces to take control of a merchant ship is incredibly unusual and marks the Trump administration’s latest push to increase pressure on Maduro, who has been charged with narcoterrorism in the United States.

The U.S. has built up the largest military presence in the region in decades and launched a series of deadly strikes on alleged drug-smuggling boats in the Caribbean Sea and eastern Pacific Ocean. The campaign is facing growing scrutiny from Congress.

“We’ve just seized a tanker on the coast of Venezuela, a large tanker, very large, largest one ever seized, actually,” Trump told reporters at the White House, later adding that "it was seized for a very good reason.”

Trump did not offer additional details. When asked what would happen to the oil aboard the tanker, Trump said, “Well, we keep it, I guess.”

The seizure was led by the U.S. Coast Guard and supported by the Navy, according to a U.S. official who was not authorized to comment publicly and spoke on the condition of anonymity. The official added that it was conducted under U.S. law enforcement authority.

The Coast Guard members were taken to the oil tanker by helicopter from the aircraft carrier USS Gerald R. Ford, the official said. The Ford is in the Caribbean Sea after arriving last month in a major show of force, joining a fleet of other warships.

Video posted to social media by Attorney General Pam Bondi shows people fast-roping from one of the helicopters involved in the operation as it hovers just feet from the deck.

The Coast Guard members can be seen later in the video moving throughout the superstructure of the ship with their weapons drawn.

Bondi wrote that “for multiple years, the oil tanker has been sanctioned by the United States due to its involvement in an illicit oil shipping network supporting foreign terrorist organizations.”

The U.S. official identified the seized tanker as the Skipper.

The ship departed Venezuela around Dec. 2 with about 2 million barrels of heavy crude, roughly half of it belonging to a Cuban state-run oil importer, according to documents from the state-owned company Petróleos de Venezuela S.A., commonly known as PDVSA, that were provided on the condition of anonymity because the person did not have permission to share them.

The Skipper was previously known as the M/T Adisa, according to ship tracking data. The Adisa was sanctioned by the U.S. in 2022 over accusations of belonging to a sophisticated network of shadow tankers that smuggled crude oil on behalf of Iran’s Revolutionary Guard and Lebanon's Hezbollah militant group.

The network was reportedly run by a Switzerland-based Ukrainian oil trader, the U.S. Treasury Department said at the time.
