Well there’s this
Blitzer: Someone supporting Hillary Clinton was trying to promote this so-called Birther issue? What happened?
Doyle: So we — absolutely, the campaign nor Hillary did not start the Birther movement, period, end of story there. There was a volunteer coordinator, I believe, in late 2007, I believe, in December, one of our volunteer coordinators in one of the counties in Iowa — I don’t recall whether they were an actual paid staffer, but they did forward an email that promoted the conspiracy.
Blitzer: The Birther conspiracy?
Doyle: Yeah, Hillary made the decision immediately to let that person go. We let that person go. And it was so, beyond the pale, Wolf, and so not worthy of the kind of campaign that certainly Hillary wanted to run.
