WASHINGTON, March 4 (Reuters) - U.S. President Donald Trump's administration said on Tuesday it is ending a license that it had granted to U.S. oil producer Chevron CVX.N since 2022 to operate in Venezuela and export its oil, after Washington accused President Nicolas Maduro of not making progress on electoral reforms and migrant returns.

Chevron will have through April 3 to wind down exports from Venezuela, according to an update of the license, published by the U.S. Treasury Department.
