It shouldn't be lost on anyone that Donald Trump us still pulling the strings behind the Republican Party's descent into fascism. This is why Republicans in Congress are fighting tooth and nail to ensure that no commission is set up for investigating the 01/06/2021 attack on the Capitol. Having the commission up and running means that some of them are likely going to be implicated in the attack's prior planning. It'll also illustrate that some figures in the Republicans' congressional leadership had also been in communication with then outgoing Trump about effectively executing the uprising.
Seeing both Kevin McCarthy and Mitch McConnell squirm at the bill's passage in the House of Representatives indicates that they likely know something in how the attempted coup was allowed to happen in the first place. So be sure to watch this pair and their seconds-in-command in the coming days as these 2 are clearly trying to cover up any potential involvement of both themselves and anyone else in their respective conferences. They're also the gateway to Trump himself (who's doing everything he can think of to keep himself out of prison), who's leading the base to force those Republicans in power to be part of his cover up effort.
Don't think that Trump isn't aware of his deteriorating legal situation, or the fact that he's likely going to be in prison, because he definitely is. If a commission is set up by Congress to investigate the uprising of 01/06, it might illustrate his level of involvement in addition to the congressional Republicans' leadership's knowledge of the event's commencement and when they knew about it.
