In earlier interviews, Obama has implied that he had never heard the Rev. Wright say anything untoward, but in the Race Speech he admitted he heard "remarks that could be considered controversial."
On CNN, he said those remarks had to do with things like "infidelity and family life," as if the Rev. Wright never aired his poisonous worldview except in a couple of videotaped sermons acquired by ABC News. This is dubious, which is probably why Obama's campaign is resisting media requests for dates when he attended services.
