I wonder if he is even a member in good standing of the New York bar.
He was practicing in DC for a while.
He is not listed as being registered to practice in NY.
His bio does not show he ever practiced in NY. He practiced in DC and his practice may be limited to the Federal Courts
The guy is a major asshole, with possibly some psychological issues if his behavior is a clue, but his not being licensed to practice in Florida is insignificant.
