Tonight... Get on On the Record with Greta!

A potentially deadly poison has been found in Great Britain today. Anti-terrorist police announced that they arrested six men of North African origin after finding traces of ricin, a deadly poison that in the past has been linked to Al Qaeda and Iraq, in a London property. Could ricin be here in the United States, too? How safe are you and your family? We'll ask a bio-weapons expert.

Plus, President Bush unveiled his plan for the economy today and the 108th Congress began to get down to business. Will the president's plan work? Will Congress be able to accomplish more than ever before? We'll ask Senators Kay Bailey Hutchison (R-Texas) and Jon Corzine (D-NJ).

Also, what's the latest on the crisis with North Korea? Former presidential adviser David Gergen will share his thoughts and we'll also discuss today's developments with our military roundtable.
