Trafficant was expelled from Congress on July 29, 2002. He was convicted on April 11, 2002. So They didn't expel him until 3 and a half months after his conviction.
Traficant didn't really want to go to jail you know so he would have pressed the issue as far as it could be pressed.
BTW, Traficant was my favorite Democrat politician.
Actually, Traficant was the best of the lot.
