The lead trial of Oath Keepers founder Stewart Rhodes and four co-defendants charged with seditious conspiracy in the Jan. 6, 2021, Capitol attack will be delayed until late September after a defense expert reported finding evidence of more communications on Rhodes’s phone with accused co-conspirators than those turned over by federal prosecutors.

U.S. District Judge Amit P. Mehta in Washington postponed a July 11 trial date to Sept. 19 or Sept. 26 after defendants said they needed more time to review what they said could be critical texts and encrypted messages involving the most high-profile person charged in the wide-ranging Jan. 6 investigation.
