[William Clayton ]
... [Sidney Rigdon (a little over a month after the murder of Joseph Smith)] related a vision which the Lord had shown him concerning the situation of the Church and said there must be a Guardian appointed to build the Church up to Joseph as he has begun it. ... Brother Marks had notified the public that next Thursday there would be a meeting to choose a Guardian inasmuch as Mr. Rigdon was in a hurry to go home again. I do not feel satisfied with this move because it is universally understood that the Twelve have been sent for and are expected here every day and it seems a plot laid for the saints to take advantage of their situation.
