A federal judge ordered the U.S. Postal Service to reverse guidelines implemented by Postmaster General Louis DeJoy to allow extra trips ensuring election-related mail is delivered.

Judge Emmet Sullivan of the District Court for the District of Columbia granted the emergency motion on Tuesday night, ordering USPS workers be informed of the change by 9 a.m. on Wednesday. According to the Hill, Sullivan made the motion against President Trump as a means to enforce a primary injunction last month, blocking the Trump administration from enforcing the postmaster’s changes.
