The House select committee investigating the January 6 Capitol attack is scheduled to hold its inaugural hearing on Thursday and according to the running order obtained by the Guardian, the panel will track the activities of the far-right Proud Boys group before and during the insurrection.

At the start of the hearing, the panel’s chairman Bennie Thompson and vice-chair Liz Cheney will make a series of opening arguments before outlining a general roadmap of how each of the six Watergate-style hearings are expected to unfold.

For the second hour, Thompson and Cheney will hand control of the hearing to Tim Heaphy, the chief investigative counsel for the select committee, who will lead the questioning of two witnesses and walk through the key moments of the Capitol attack.

The select committee is expected to start the questioning with testimony from Nick Quested, a British documentary film-maker who was embedded with the far-right Proud Boys group in the days and weeks leading up to January 6 and caught their activities on camera.

Quested, appearing pursuant to a subpoena, is likely to deliver his own opening remarks and testify about how the Proud Boys planned their January 6 operation in detail in the weeks before the Capitol attack, narrating and analysing the footage that he recorded.

By examining several crucial stages in the lead up to the first breach of the Capitol by the pro-Trump mob – such as the march to the Capitol from the Ellipse and a short stop at the Statue of Peace at the foot of Capitol Hill – the panel will show how the attack came to pass.

The select committee is then expected to focus on the moment that Joseph Biggs, a member of the Proud Boys charged with seditious conspiracy on Monday, had a brief exchange with a man in the crowd near the statue just before the march morphed into the Capitol attack.

Biggs’ exchange with that man, Ryan Samsel, is widely seen as the tipping point that precipitated the riot. Samsel, who has been charged with attacking police, then walks up alone to the barricade and confronts US Capitol Police officers before pushing it over.

The select committee will illustrate Quested’s testimony about how that incident unfolded by playing footage leading up to that moment and a photo Quested took of the moment that Samsel is about to confront and then push past the officers.

Heaphy is expected at that point to have the second witness, US Capitol Police officer Caroline Edwards, testify about her recollections of those key minutes during which she was assaulted by another man who had been speaking with the Proud Boy member.

The testimony by Edwards, who was the first officer injured in the attack, is expected to be harrowing. Edwards, the New York Times reported, was knocked backwards into concrete steps by the surging pro-Trump mob that overturned the bike rack-like barricade on to her.

Heaphy is expected to return to Quested to have him analyse other moments that he caught on camera as the Proud Boys led the charge up to the inaugural platform elected for Biden’s swearing-in weeks later, and then smashed a window in order to enter the Capitol.

But in a notable omission, the select committee is not expected to use Quested’s footage of Enrique Tarrio, the leader of the Proud Boys, meeting with Stewart Rhodes, the leader of the far-right Oath Keepers militia group, at a secret rendezvous the night before.

The justice department has cited that meeting, which took place in an underground parking garage near the Capitol, in seditious conspiracy indictments against Tarrio, Rhodes, and other members of both the Proud Boys and Oath Keepers groups.

Quested is considered the star witness in the select committee’s inaugural hearing, which will be covered live by most of the major US cable news networks, including MSNBC, CNN, CBS and ABC. Fox News will have its top-rated host Tucker Carlson deliver counter-programming.

The Emmy award-winning documentary film-maker spent much of the post 2020 election period filming Tarrio and the Proud Boys – with their permission – and has testified multiple times to the panel in closed-door depositions.

Quested had accompanied the Proud Boys to a number of pro-Trump rallies in Washington DC in November and December 2020, and was with the Proud Boys as some of its members stormed the Capitol. He also filmed Tarrio’s reaction to the riot later on January 6 in Baltimore, MD.
