One of these agencies is not going to comply. And then what? Trump is already pushing the legal “theory” that the judiciary cannot check the executive. This is bound to end up in front of the Supreme Court, and who knows what those guys will do?
If I were Trump or Vought I'd be over the moon about this ruling. A lowly district judge telling the president what to put on a federal agency's website. No idea about the legal side, but the optics are great for Trump.
