A permit issued by the United States government allowing energy giant Chevron Corp. to pump and export Venezuelan oil will be terminated this week.

The United States is rescinding a Treasury license allowing Chevron to produce and export oil from Venezuela, despite U.S. sanctions, President Donald Trump said Wednesday, because President Nicolás Maduro was not legitimately elected and has not accepted Venezuelans deported from this country fast enough.

President Trump’s immigration agenda, an entrenched regime’s interests and an oil industry lobbying campaign have all played a part.
