Well, we already heard this from Rosie and yet, I still feel the need to share what Kathy Griffin, who co-hosted "the View" the day after the big fallout, had to say about it all.
According to TMZ.com: It was the show's technical decision to sensationalize the recent on-air fight between Rosie and Elisabeth Hasselbeck with a split screen graphic. that pushed O'Donnell over the edge. "I said, 'What was it really?'" recalled Griffin. "'The split-screen." She said, 'I don't want to do "Hannity and Colmes."
Griffin also revealed that O'Donnell's hard feelings toward Hasselbeck might not run so deep. When Rosie heard that Donald Trump had called Hasselbeck "stupid," she expressed sadness. "She doesn't even hate Elisabeth," said Griffin.
