It's true that nobody wanted trump in office, I doubt there was a conspiracy. Then he repeatedly and egregiously violated just about every law and tradition there is. Russia did interfere in the election in 2016 and the evidence of this is in the Mueller report. The section that talks about this is redacted because, at the time of its release, that information was part of an ongoing investigation. Bill Barr unlawfully obstructed the original investigation and tried to hide it, but he failed.
Several republicans, including a particularly nasty shit heel named Kevin McCarthy, have made threats in the past to this effect. I would not put it past them. McCarthy, McConnell, Paul, Graham, Scott, Boebert, and Blackburn are all snakes. Blackburn is a KKK member. None of these people were happy when trump got handed his buttocks in 2020. They all supported the big lie and faux helped them brainwash the MAGA crowd.
These are the kind of people that would seek retribution.
