At the very least, Roberts should be asked the same question again, under oath, at his confirmation.
Gee, who would that "oath" be to? Mickey Mouse, Dumbo, or in Hitchens' case, the impersonal and totally meaningless dialectics of history? [irony, sarcasm] What the heck does an anti-Christian atheist care whether it is "under oath" or not? He wins a Twilight Zone Award for that one.
How long till they modify the oath for testimony? Have they done that already?
