- Allegedly Sidney Blumenthal urged a reporter to investigate where Obama was born, suggesting it was Kenya. This was denied by Blumenthal and appears to be a misread or exaggeration of an email Blumenthal wrote. (http://www.mcclatchydc.com/news/politics-government/election...)
- Mark Penn wrote a strategy memo about Obama's "lack of American roots" in reference to him having lived abroad, which the campaign never acted on. (https://www.theatlantic.com/magazine/archive/2008/09/the-fro...)
- A volunteer coordinator in Iowa forward an email promoting birtherism and was fired for doing so. (http://www.politifact.com/truth-o-meter/article/2015/sep/25/...)
I have a hard time reconciling "very active in birtherism" (or promoting birtherism at all by the campaign, much less Clinton herself) with these incidents. If you've got other references, please share. (Though this is really far off the reservation with respect to the submission.)
