Rosie didn't want to stick around and have an intelligent conversation and she has asked for an early exit from her contract at ABC. Throughout the whole argument on the view, Rosie wouldn't let Elizabeth speak and she kept raising her voice.
She is a bitter person.
She is a good actress, has worked on many projects and done some pretty good things in this world. But she has gone of the deep end on this one.
