President Trump said Wednesday he was revoking a Biden-era license allowing Chevron to produce oil in Venezuela over what he said was strongman Nicolás Maduro’s failure to assist in deporting migrants.

Oil prices edged up from two-month lows on Thursday after U.S. President Donald Trump announced a reversal of a license given to Chevron to operate in Venezuela, potentially tightening crude supply. Brent crude oil futures rose 19 cents or 0.

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