You are mistaken. SCOTUS is simply asking for briefings on whether they should take the case. I think it is highly unlikely they would take this case. These are two substantial issues which deal with presidential immunity, which means that the Supreme Court would want appellate judges to weigh in first. Everybody in DC legal circles knows that the trial judge is deliberately trying to speed up the case.
I write briefs for a living. Just now, I needed more time than this on something much less weighty.
