Congress has no law enforcement authority or jurisdiction.  All Congress can do is make referrals to the DoJ.  I would be surprised if there is any kind of action taken by DoJ against President Trump.  To date I haven't heard anything except speculation, hearsay, and innuendo from the Jan. 6th committee.  If they had actually found any real evidence that he broke a law I think we would have all heard about it by now.  But that's not the point of the Jan. 6th hearings.
