As federal investigators try to trace the origin of suspected ricin found Monday in the office of Senate Majority Leader Bill Frist, ABCNEWS has learned of an earlier, undisclosed incident in which a ricin-laced letter was intercepted on its way to the White House.
In November, a letter postmarked Chattanooga, Tenn., and addressed to the White House was intercepted at an off-site mail sorting facility in the Washington area, sources told ABCNEWS.
Hmm. Wonder why they kept it secret.
UPDATE: Alex Knapp has suspicions about where the ricin came from. You’d be a fool not to think that way — but bear in mind that ricin isn’t that hard to make.
