Trump then added, “Go ahead, I’m going back to Chevron. Thank you, Marco.”

The message referred to oil company Chevron, which produces about 150,000 barrels of oil per day in Venezuela, according to CNN. Chevron is among the oil firms in discussions with the White House over potential investment in Venezuelan oil infrastructure and is one of the more established companies operating there.

Rubio’s expression suggested he was not pleased that Trump had read the message publicly. Trump even slapped him on the back and laughed afterward.

The meeting also highlighted that Venezuela may not be the only foreign target on Trump’s agenda. He reiterated his interest in Greenland, claiming national security concerns and warning that if the U.S. doesn’t act there, Russia or China might.
