At the Congressional hearings on bacteria-tainted peanut products, Representative Greg Walden, Republican of Oregon, showed a
jar of peanut butter to Stewart Parnell, owner of the Peanut Corporation of America. The jar was wrapped in "Crime Scene tape". Representative Walden invited Mr. Parnell to eat some of the peanut butter. Mr. Parnell declined to answer his request; invoking the protections afforded him under the U.S. Constitution.
