What I remember him saying was he gave some speeches for mannatech, that he speaks before many groups,he didn't know they had his pic on their homepage, and finally that he uses their supplements, and feels they are good products.
My initial interpretation was the moderator was trying to make it appear he had a relationship with a company for whom he had only given a speech for remuneration.
However, as the exchange between the moderator, and Carson continued, I thought he was trying to obfuscate, and his relationship to the company was more than just a paid speech, and a picture they posted of him without his knowledge or permission
Agreed.
