Two mailings that contained the deadly poison ricin were intercepted at a U.S. Postal Service facility in Spokane this week.
The Spokane Spokesman-Review, quoting the American Postal Workers Union, reported that one was addressed to a federal judge and the other to the Spokane post office.
The FBI is investigating the incident, but providing few details.
The FBI says there have been no reports of illness connected to the letters, which were intercepted Wednesday.
The FBI, along with Postal Service investigators, is searching for the sender of the letters, which were post-marked Tuesday in Spokane.
Ricin is a highly toxic substance made from castor beans. As little as 500 micrograms -- an amount the size of the head of a pin -- can kill an adult.
