U.S. President Donald Trump on Wednesday said he was reversing a license given to Chevron to operate in Venezuela by his predecessor Joe Biden more than two years ago, accusing President Nicolas Maduro of not making progress on electoral reforms and migrant returns.

The Trump administration formally revoked on Tuesday the license that allows oil giant Chevron Corp. to sell Venezuelan oil in the United States, giving the U.S. company only 30 days to wind down its operations in the South American country.
