taped scarborough at 3 am and saw no interview. I did see the local ABC news which reaired and there was the sign held by raoul.
You are right that Raoul was NOT interviewed.
Doctor Raoul and his sign were shown for about ten seconds as they came back from commercial to continue discussion between Scarborough, Carl Bernstein (whose shabby attempts to excuse Clinton's misconduct were demolished by Scarborough), and former House impeachment manager Bill McCollum.
Scarborough said something like, "here's what a heckler said at the book event. My guys want me to read his sign, but you can read it yourself. Clinton may not be able to avoid, these issues."
