Madame Secretary,
You are making the assumption that those of us who have a life outside of the LNC know anything about the "clear wrongdoing of the chair." You have asserted that it's clear in multiple places now, but while it may be clear to you, I have seen no evidence of wrongdoing.
If he signed a letter (as Mr. Hall suggested was his understanding) that attested to the fact that Ms. Jarvis was the state chair, I'm not sure how that is "wrongdoing." There are any number of reasons why they may have needed a letter like that (bank accounts, recognition by the state or other election entity, etc.). This seems like a pretty pro forma action, in and of itself.
Now, if you have any proof that the chair knew that this was going to happen, and that his letter would be used inappropriately, I would suggest you present that evidence. I assume that you have said that it is "clear wrongdoing" that you have evidence to back that up.
It's not at all clear to e that there was anything to bring up to the LNC last week at this time, aside from the assorted grumblings that we were all seeing already online.
Laura
