Republican appointed judge - put it in the FUCKING headline. Stop pretending that the idea of an impartial judiciary is possible today. The context matters.
My understanding is that the temporary nature is supposed to be because the plaintiffs need time to advance their case, which they got. The extension is now incredibly damaging to all of the people who would have had their student debts reduced. Every day that goes by is an extra burden on them, but the judge doesn't care.
