Yes. He wasn't by far the only one involved in rumors that the Clintons had something to do with the deaths. Not sure how involved he was, if at all, with the Travel Office. I would have to research that to refresh my memory.Vince Foster who was deeply involved was found dead.
My recollection though was that Robert Fiske, special prosecutor, investigating White Water, also got involved in the investigation of Foster's death and then the Travel Office fiasco too, so maybe there was a connection. Who knows? At any rate when Ken Starr took over from Fiske he investigated all of that stuff and then the Paula Jones scandal surfaced leading to the Lewinsky scandal and it all was a big ugly sordid mess. The prosecutors didn't get Clinton on White Water or the suspicious death, and probably the Travel Office was deemed improper and politically motivated if not flat out illegal. But there were felonies involved re perjury and obstruction of justice charged in the sex scandals.
