In Washington, the investigation into whether the recent discovery of the deadly toxin 'ricin' in the U.S. Senate is connected to a similar incident that occurred last November at the White House is still ongoing. On Tuesday, sources from law enforcement confirmed that the white powder sent to the White House at that time was ricin -- a deadly toxin derived from castor beans, for which there is no antidote. However, these sources stated that the toxin sent by mail was not very potent and posed no danger to anyone. Senator Bill Frist, the majority leader in the U.S. Senate, stated that three Senate buildings, which were closed last Monday afternoon after the discovery of ricin in his office, will reopen within the next week. Mr. Frist mentioned that none of the individuals who were exposed to the toxic substance in that office became ill.
