According to the docket, USA v. Davis proceeded to jury selection on Monday, but the trial was then continued:
Minute Entry for proceedings held before Judge Leonard P. Stark - Jury Selection as to Aaron Davis held on 11/16/2020 (Court Reporter B. Gaffigan.) (etg) (Entered: 11/17/2020)
ORDER: IT IS HEREBY ORDERED that the Jury Trial is CONTINUED. The government shall file a joint status report due by 11/30/2020. A Telephone Conference is set for 12/1/2020 at 01:45 PM before Judge Leonard P. Stark. Time is excluded from 11/17/2020 until 12/1/2020. Signed by Judge Leonard P. Stark on 11/17/2020. (etg) (Entered: 11/17/2020)
The order states only that the trial was continued "for the reasons stated in court November 16, 2020," but I understand that Chief Judge Stark stated in court that he decided to continue the trial due to coronavirus concerns, in light of the Delaware State Courts' decision on Monday to revert to Phase 2 of their re-opening plan and to stop all jury trials.
