FBI links senate anthrax letters

The FBI believes an anthrax-laced letter to US Senator Patrick Leahy, belatedly found last week, was written by the same person who sent a tainted letter to Senator Tom Daschle last month.

Investigators said yesterday they were also looking into the possibility that the letter to Leahy was misdirected, which could have been the source of anthrax contamination at a State Department mail centre that made one worker ill.
