In this exclusive story, CBS News chief investigative correspondent Armen Keteyian reports the latest terror attack to America involves the possible use of poisons – simultaneous attacks targeting hotels and restaurants at many locations over a single weekend.
A key Intelligence source has confirmed the threat as “credible.” Department of Homeland Security officials, along with members of the Department of Agriculture and the FDA, have briefed a small group of corporate security officers from the hotel and restaurant industries about it.
The plot uncovered earlier this year is said to involve the use of two poisons – ricin and cyanide – slipped into salad bars and buffets.
