U.S. District Judge Timothy Kelly postponed the beginning of the trial from August 8 to December 12 after attorneys for many of the men claimed that their clients couldn't get a fair trial by an impartial jury in the midst of televised hearings by the House committee examining the Capitol attack.
They're further waiting for the committee to share documents that could become trial evidence.

Former Proud Boys national chairman Henry "Enrique" Tarrio and four different men are charged with seditious conspiracy for what authorities say was a plot to forcibly oppose the lawful transfer of presidential power throughout the joint session of Congress on Jan. 6, 2021.

Tarrio, 38, of Miami, and his co-defendants - Ethan Nordean, Joseph Biggs, Zachary Rehl and Dominic Pezzola - have been in federal custody for months.
Their trial is expected to last four to six weeks, stretching into next year.
Tarrio questioned Judge Kelly to order his release on bond, yet the judge maintains that the evidence against Tarrio is very strong, despite the ex-Proud Boys leader's claims otherwise.

Biggs, Pezzola and Rehl asked for the trial to be delayed. Biggs' lawyer, J. Daniel Hull, stressed that the House committee isn't expected to release hundreds of deposition and interview transcripts until after an August trial would have begun.

"The transcripts are must-haves for trial preparation," Hull wrote.
Justice Department prosecutors consented to the delay. They announced the House committee's failure to share the deposition and interview transcripts is further hampering their ability to investigate and prosecute January 6 defendants.

Tarrio objected to delaying the trial.
"Tarrio believes that an impartial jury will never be achieved in Washington, D.C., whether the trial is in August, December, or next year," his lawyers wrote.

Nordean's attorneys objected to delaying the trial for months while keeping Proud Boys leaders locked up in pretrial detention.
Police arrested Tarrio in Washington two days ahead of the Capitol riot on Jan. 6, 2021, and charged him with vandalizing a Black Lives Matter banner at a historic Black church throughout a demonstration in December 2020. This led to a judge ordering Tarrio to stay out of the country's capital.
Tarrio then wasn't in Washington when the riot erupted, yet authorities say he helped put into motion the violence that disrupted Congress from certifying Biden's victory over President Donald Trump.
