Sorry I didn't understand your question.
When on the Senate Floor during debates a Senator will say something and Byrd will respond quite loudly, "THAT IS NOT IN THE CONSTITUTION" or " THAT IS NOT WHAT THE CONSITUTION SAYS."
Then he will proceed to pull out the well worn copy of the Constitution he keeps in his vest pocket, turn right to the exact page and paragraph in question. Everytime I have been watching he was always correct in his assertion
Well, all right, though I don't think any of that qualifies a guy as a "constitutional historian", which to me implies a guy much more solid on background, how constitutional principles were developed, where they came from, etc. Maybe if he had said, "That's NOT what George Mason said during his losing argument about slavery at the Constitutional Convention!" I'd be more impressed.
