...we investigated this and below is a response from Clinton campaign manager Patti Solis Doyle:

"There is no place in our campaign, or any campaign, for this kind of politics. A volunteer county coordinator made the mistake of forwarding an outrageous and offensive chain e-mail. This was wholly unauthorized and we were totally unaware of it. Let me be clear: No one should be engaging in this. We are asking this volunteer county coordinator to step down and are making it clear to every person involved in our campaign that this will not be tolerated."
