I just found out the origin of the rivalry/animosity between Donald Trump and Rosie O'Donnell. It dates back to a 2006 episode of The View where Rosie basically badmouths Donald and the Miss USA pageant. The YouTube video clip was re-posted on MSNBC, who quoted Rosie's responses to Donald's debate insult. P.S. — I'm not a fan of O'Donnell, not remotely a fan of Oprah or The View or any such talk shows. But this Donald-Rosie feud is fascinating.
