A federal judge on Friday extended her prohibition against the U.S. Postal Service implementing President 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 has already asked the Supreme Court to lift Talwani's temporary order, and will likely appeal her latest ruling as well.
