A federal judge is extending a legal block on President Donald Trump’s plan to regulate mail ballots during the midterm elections. The order Friday from U.S.

A federal judge on Friday extended her prohibition against the U.S. Postal Service implementing Donald Trump’s executive order seeking to limit mail voting during the midterms, putting another major obstacle in the way of the administration as the first states begin sending out mail ballots.

The preliminary injunction from U.S. District Court Judge Indira Talwani replaces a temporary order she granted blocking the Postal Service’s plan.

The Trump administration had already asked the Supreme Court to lift Talwani’s temporary order, and on Friday it informed her that it would appeal her latest decision to the U.S. 1st Circuit Court of Appeals.

The administration is running out of time to make big changes in voting procedures, though. North Carolina began sending out its first mail ballots Friday and more states will swiftly follow.
