Footnote 3 from the presiding judges ruling:
3 Should any defendant who has not yet filed a waiver invoke the statutory speedy trial deadline before the trial of Defendants Chesebro and Powell has commenced, those defendants will immediately join the October 23rd trial.
That’s a tough call for Trump and his legal team.
Should he join the October 23 trial or waive his rights to a speedy trial and sit by as prosecutors present evidence in court live on camera of Trump’s role in the RICO crimes.
Chesebro and Powell will of course be represented in court, but their lawyers are not in court to challenge any evidence or testimony against Trump, they are there to defend Chesebro and Powell.
