Packages with suspected ricin sent to Pentagon, Navy chiefs

WASHINGTON (AP) — Authorities at a Pentagon mail screening facility found two envelopes suspected of containing ricin, a poison made from castor beans, and turned them over to the FBI for further analysis, officials said Tuesday.

One envelope was addressed to Defense Secretary Jim Mattis, who is traveling in Europe this week, and the other to the Navy's top officer, Adm. John Richardson, a defense official said. The official spoke on condition of anonymity because the official wasn't authorized to speak publicly ahead of FBI release of its findings.

Neither envelope entered the Pentagon. The mail screening facility is on the Pentagon grounds but separate from the main building.
