Glad I watched this. I had assumed this was a post of a video I watched yesterday - it's not. However, it is another example of how the media is misrepresenting what Trump is saying. Trump did NOT bring up The Apprentice, the interviewer did. Trump did NOT bring up the birth certificate, the interviewer did. I have not seen a single interview where Trump introduced the topic of the birth certificate.
In fact, I believe I may have watched the first time Trump talked about the birth certificate. The segment BEFORE the Trump segment the host of the show (can't remember who, but was male on one of the cable news shows that is not Fox - maybe MSNBC) who had been in attack mode about the birth certificate with a male guest. Back from commercial and the host was still frothing at the mouth and asked Trump if he could believe how stupid people could be to not believe Obama was US born. Trump gave a perfunctory Obama should just show it and end it. The host went off again and gave Trump interest in the subject.
