A permit issued by the United States government allowing energy giant Chevron Corp. to pump and export Venezuelan oil will be terminated this week, President Donald Trump announced Wednesday, ending what became a financial lifeline for the South American country.

Trump’s announcement accused the government of President Nicolás Maduro of not meeting democratic conditions for last year’s July presidential election as well as of not moving fast enough to transport back to Venezuela immigrants set for deportation.

“We are hereby reversing the concessions that Crooked Joe Biden gave to Nicolás Maduro, of Venezuela, on the oil transaction agreement,” Trump wrote.

Trump's post did not specifically mention California-based Chevron nor the permit, formally known as a general license, that exempts the company from economic sanctions and allows it to export and sale Venezuelan oil in the U.S.
