Let's talk about the committee, the symbolic, and civics....

A symbolic referral was easily predictable, as are those in his orbit from the Willard Hotel. Do the criminal referrals extend to members of Congress and the Senate? The data still goes, so it matters less, provided that the guilty members are investigated by Mr. Smith. 

The Committee gets an C for referring only 4 members to the Ethics Committee and then, only citing not answering the subpoena. They punted. They also limited the number referred to less than the new majority. They were likely so afraid of being seen as political that they put their thumb on the scale, even though assisting an insurrection was a political act. Not referring these members is a failure to enforce the 14th Amendment.

There is a point when the new Congress convenes to challenge disputed elections. Does being a traitor rise to the level of disputability? We shall see. If they were to go this route, they would have to then refer the members not seated to Ethics anyway and, to not look political, suspend the election for Speaker until members or cleared or a special election is held for each member not seated.

For the moment, Jack Smith is the hope for the 14th Amendment meaning anything. Immediate indictments would be nice, but justice will soon come for insurrectionist members. If they plead guilty or are convicted, they will have to resign or be removed. Again, there will be a special election to fill their vacancy. Because the nation is mostly even, they will likely be replaced with other Republicans. This is why they should simply resign now.

As for certain Insurrectionist Senators, they will be replaced by their governors. In at least two cases, those governors are Democrats. Replacing just one defangs the two conservative Democrats.
