The most important thing to remember about the formation of the select committee to investigate the January 6 Capitol riot is this: Speaker of the House Nancy Pelosi gave Republicans multiple opportunities to act as good faith investigators who want to help reveal the truth, instead of as insurrection co-conspirators who are running interference for Donald Trump.
Democrats tried to create a bipartisan committee through official congressional legislation, but Republicans stopped them. Democrats then went at it by themselves, creating a select committee with the House leadership powers, yet still decided to invite Republicans onto the commission as an act of good faith. All Republicans needed to do was act like adults who believe fascist coups are bad business, instead of a bunch of clowns whose only goal is to disrupt the proceedings. House Minority Leader Kevin McCarthy, however, could not pass this basic "adults or clowns?" test. He picked clowns, including Rep. Jim Jordan of Ohio, who has a pair of the biggest shoes and some of the thickest greasepaint in the highly competitive field of authoritarian buffoons of the GOP. Picking the QAnon shaman would have been a more subtle effort at sabotage, but "subtle" isn't exactly a popular aesthetic in Republican circles today.
And so Pelosi did what any sensible person who wants a real investigation instead of a conspiracy theory circus would have done: She said no thank you to Jordan and Jim Banks, R-Ind., who honks his nose less loudly than Jordan but is no less a far-right saboteur.
