started by the hillary clinton campaign in 2008 against barack obama. and i recognize that there are folks online that like to push that issue. >> in a radio interview this morning, clinton was asked about her alleged birtherism as well as a claim that in 2007 she and obama had a heated confrontation over clinton allegedly circulating e-mails claiming obama was muslim. >> did you or your campaign start the whole birther thing? and did you -- >> that is so -- >> did you have a confrontation with the president? >> no, that is so ludicrous, don. you know, i just believe that -- first of all, it's totally untrue. and secondly, you know, the president and i have never had any kind of confrontation like that. >> now, when i was a reporter over at "the nation" in 2007, i reported this out. i took a long look at all the smear rumors circulating around barack obama, including one much forwarded e-mail accusing him of being a secret muslim. and i traced the claim to a 2004 press release by a lawsuit filer who had gone to claim on fox news channel without evidence
