The USSC scheduled this as late as possible (the last week in its 2023-24 term), and will probably issue a ruling as late as possible (July 1st). Justice has been delayed. This delay is disappointing for those who want some personal accountability for J6. I remain optimistic that the voters will reject Trump's dystopia, and our justice system will work. Delaying the trial until after the election makes it more likely loser Trump will be found guilty as charged.

The framing of the question by the USSC is bizarre. Why insert a gratuitous "alleged"? Some possible different phrasing of the issue:

A. Whether and if so to what extent does a former President enjoy presidential immunity from criminal prosecution for conduct alleged to involve official acts during his tenure in office.

B. Whether and if so to what extent does a former President enjoy presidential immunity from criminal prosecution for official acts during his tenure in office.

C. Is a former President immune from criminal prosecution for his official acts?

Of course, all of this is unnecessary in Trump's case because the conduct (campaigning) was private conduct.

"In the civil context, the Supreme Court has explained that a former President is absolutely immune from civil liability for his official acts, defined to include any conduct falling within the “‘outer perimeter’ of his official responsibility.” Both sitting and former Presidents remain civilly liable for private conduct."
