Ricin…

…in the Dirksen Senate Office Building? That’s what preliminary tests indicate. An envelope containing the suspicious powder was found in Bill Frist’s mail room. Ricin was Ansar al Islam’s specialty. It would be ironic if, at the height of the hysteria over Iraq having no biological weapons, they were to turn up in the Senate Office Building. As far as I know, however, there is no way to trace the source of the toxin, should it turn out to be ricin.
