Chesebro, who was charged alongside Donald Trump and more than a dozen other codefendants with attempting to delay the transfer of power after the 2020 election, was scheduled to stand trial this week. He accepted the offer as jury selection was underway on Friday, and after rejecting an earlier deal.
I think because Powell and Chesebro were the only two that requested a speedy trial. The others cases will still happen, just not until later.
