Uhhh...wasn't Traficant convicted on felony charges?
Yes and he is serving time for that. Thus due to the double jeopardy clause of the constitution he cannot be arrested for that charge again. Any arrest would have to be a new charge. Of course escaping from custody would most likely be a felony, but leaving to attend a function for which he was duly elected might not be a crime. At least he has an argument in my mind for furlough to attend.
