I can only think of two people who might have the courage to publically ask them, and that is Sean Hannity (VERY doubtful) and Michael Savage (who would, but would never be given the opprotunity to ask).
Can't you just hear the cacophony from Alan Colmes and the communist guest would launch into IF Hannity ever had the cajones to ask?
Rush? Never. Not his style.
Who else is left?
O'Reilly would do it .. but he would have to have alot of proof before we would do something like that
