I doubt Judicial Watch has standing to file a complaint insofar as they were not harmed. In any case, I’m very happy that the American public got to witness the whole thing live.
Had the Judiciary committee gone to her the true nature of the events would have been clouded. We should rejoice in their incompetence.
I think you need to be harmed to file a lawsuit, but not a complaint. For example, lawyers can file complaints against judges for judicial misconduct even though the "harm", if any, was to the clients and not the lawyers. I could be wrong, though.
