A federal judge in Boston has handed the Trump administration another temporary win in the legal fight over the president’s executive order to restrict mail-in voting for the midterm election.

U.S. District Judge Indira Talwani on Wednesday canceled a nationwide ruling she had issued that blocked the U.S. Postal Service from working on Trump’s directives.

The decision sets the stage for another possible consideration of the executive order by the Supreme Court. So far, the high court has ruled on a procedural issue, but not weighed in on whether Trump’s order is legal.
