They're trying to do an end-run around the 2/3 provision, though. Instead of using that to un-disqualify him, they are trying to get a simple majority to state "He never did those things in the first place", and contradict the Colorado judge.
I'm pretty sure that's not how the law works, though. Congress makes law, and judges interpret it. While there's still an open issue on who gets to declare that the provisions of the amendment have self-executed, Congress can't simply declare "It never happened" and make that declaration have any force.
The only purpose of this resolution is to throw a bone to the MAGAs. Which, ironically, can be seen as inciting another insurrection. So these people might be signing their own disqualification if it leads to another MAGA tantrum on Federal buildings in DC.
