The House committee investigating the Capitol attack has sent subpoenas for records and testimony from Ali Alexander and Nathan Martin, organizers of the Stop the Steal rally.

A third subpoena was sent to George Coleman, the registered agent of Stop the Steal LLC, and asks for the custodian of records for the entity to produce records and testify before the panel.

“The rally on the Capitol grounds on January 6th, like the rally near the White House that day, immediately preceded the violent attack on the seat of our democracy,” Committee Chairman Bennie Thompson, D-Miss., said in a statement Thursday. “Over the course of that day, demonstrations escalated to violence and protestors became rioters. The Select Committee needs to understand all the details about the events that came before the attack, including who was involved in planning and funding them. We expect these witnesses to cooperate fully with our probe.”

Stop the Steal was a rally and effort to overturn the results of the 2020 presidential election.

Martin’s phone number and email was listed on a permit application that the organization “One Nation Under God” submitted to the Capitol Police for a rally on Jan. 6 at the Capitol concerning “the election fraud in the swing states.” A vendor listed on the permit told Capitol Police he was reporting to Martin and Alexander and that both were affiliated with Stop the Steal. The permit application did not disclose a connection between the Capitol rally and Stop the Steal.

After the deadly insurrection by supporters of former President Donald Trump, Alexander said Stop the Steal obtained the rally permit for the “One Nation Under God” event.

It has been reported that leading up to the Jan. 6 attack Alexander said violence could be used to advance Stop the Steal’s goals and that he said he was in touch with the White House and members of Congress. Alexander, according to reports, spoke at an event on Jan. 5 by the Eighty Percent Coalition in Washington, D.C., where he led a chant that said “victory, or death.”

Martin and Alexander are required to produce records to the committee by Oct. 21 and sit for depositions on Oct. 28 and 29, respectively.

Fifteen subpoenas have been sent in past weeks to others involved in the planning and organizing of events before and on the day of the insurrection, including members of Women for America First, the group that organized the Jan. 6 rally at the Ellipse.

The committee also subpoenaed four people who were close to Trump leading up to or on the date of the attack: Mark Meadows, then the White House chief of staff; Dan Scavino, the White House deputy chief of staff for communications; Kashyap Patel, a former Pentagon official; and Stephen Bannon, a former White House adviser.
