The incident dates to a meeting of Iowa Republican activists in April, where McCain's Warren County chairman, Chad Workman, is alleged to have made negative comments about The Church of Jesus Christ of Latter-day Saints and the Mormon faith. Romney is a Mormon.
A participant at the meeting said Workman questioned whether Mormons were Christians, and he referenced an article alleging that the Mormon church supports the Islamic militant group Hamas. The participant talked to The Associated Press on Friday on condition of anonymity because he is involved in Iowa politics and wanted to protect his identity.
In response to a question on whether Mormon women were more likely to be stay-at-home mothers, the participant said Workman associated the treatment of Mormon women with the Taliban.
